Lériendil: added white dwarf

This page collects deleted entries of [[regular temperament]]s from the Xenharmonic Wiki due to not meeting our [[Xenharmonic Wiki: Notability guidelines|notability guidelines]], although other materials may still reference them. We recommend to refer to these temperaments with an ET [[join]] (e. g. "11-limit 12 & 85") or as a [[restriction]] of a different temperament (e. g. "no-7's cassandra").

== Extensions ==
It makes little sense to consider gaster as a full 41-limit temperament. I think it's best to clip it after the 23-limit since the 29-limit sees a relative large increment in badness, and since prime 29 is on the opposite side of most other primes in the generator chain.

This temperament is also signficantly less accurate in the 7-limit than the 5-limit, so one of them should have its name changed. I think it's best to change the name of the 5-limit temp.

=== Overview to extensions ===
The full 7-limit extensions' relation to canopus is clearer if the mapping is normalized in terms of 3.5.7.2. In fact, the strong extensions are nusecond and octoid. These temperaments are distributed into different temperament collection pages.
* ''[[Nusecond]]'' (+126/125) → [[Starling temperaments #Nusecond|Starling temperaments]]
* ''[[Octoid]]'' (+4375/4374) → [[Ragismic microtemperaments #Octoid|Ragismic microtemperaments]]

The others are weak extensions. Mirkat tempers out [[19683/19600]], splitting the generator in two with a semitwelfth period. Sqrtphi tempers out [[15625/15552]], splitting the period in six. Semisept tempers out [[1728/1715]] and [[3136/3125]], splitting the generator in six. Miracle tempers out [[225/224]]. Pluto tempers out [[4000/3969]]. These split the generator in five. Kwai tempers out [[5120/5103]], splitting the generator in ten. Quanharuk tempers out [[32805/32768]], splitting the generator in three with a 1/5-twelfth period. Grendel tempers out [[6144/6125]], splitting the generator in eleven. Finally, eris tempers out [[65625/65536]], splitting the generator in sixteen.

== Gaster ==
: ''For the 5-limit version, see [[Very high accuracy temperaments #Gaster]].''
{{Main| Gaster temperament }}

Gaster tempers out {{monzo| -70 72 -19 }} in the 5-limit, mirkwai comma (16875/16807) and [[scheme comma]] (14348907/14336000) in the 7-limit, and may be described as the {{nowrap| 111 & 113 }} temperament.

It was named by [[Xenllium]] in 2022; the word "[[Wiktionary: gaster|gaster]]" means [[Wiktionary: abdomen|abdomen]] or [[Wiktionary: stomach|stomach]], but also a restructuring of the words "gassormic tritone", which is a generator of this temperament. This temperament is sufficient to obtain high prime limit harmonics like a stomach, so that patent vals [[111edo|111]], [[113edo|113]] and [[224edo|224]] support it even in the 41-limit.

== Browser ==
{{See also| Sensipent family }}

Named by [[Xenllium]] in 2022, browser may be described as the {{nowrap| 103 & 111 }} temperament.

This can also be considered a [[non-over-1 temperament]], with considerable scope for harmony in the 2.5/3.7/3.11/3.13/3.17/3 subgroup with mos scales of 8, 15, 23, and 31 notes despite no harmonics from the root. It can be considered a detemperament of 8d-et, with a generator very slightly flat of 7\8.

The '''canopus comma''' ([[ratio]]: 16875/16807, {{monzo|legend=1| 0 3 4 -5 }}), also known as the ''mirkwai comma'' or ''small BP diesis'', is a [[small comma|small]] [[7-limit]] [[comma]] measuring about 6.99 [[cent]]s.

== Temperaments ==
Tempering this comma out alone in the 7-limit leads to the rank-3 [[canopic]] temperament and the [[canopus family]]. It is tempered out in rank-2 temperaments such as [[miracle]], [[octoid]], [[semisept]], [[grendel]], [[kwai]], [[pluto]], and [[mirkat]], which comprise the [[canopus clan]] for a collection of rank-2 temperaments where it is tempered out.

== Etymology ==
''Canopus'' is named after the 3.5.7 temperament [[canopus]], following a convention of naming tritave-based regular temperaments after stars.

The name ''mirkwai'' was given by [[Gene Ward Smith]] in 2005 as a contraction of ''[[miracle]]'' and ''[[kwai]]''<ref>[https://yahootuninggroupsultimatebackup.github.io/tuning-math/topicId_12900.html Yahoo! Tuning Group | ''Seven limit comma names from pairs of temperament names'']</ref>.

The name ''small BP diesis'' was given in <ref>[https://www.huygens-fokker.org/bpsite/names.html The Bohlen-Pierce Site | ''BP Names and Definitions'']</ref>.

Talk:5120/5103

2026-06-01T20:18:00Z

Lériendil: /* Petition to officialize aberschisma, and change hemifamity to aberschismic */

== "Universal" name for 5120/5103 ==

I've noticed the conversation on the XA Discord about picking a name to replace "hemifamity comma". Suggestions I've seen include ''argent comma'' and ''pele comma''. I'm a bit biased towards ''aberschisma'' since I coined the name, but MidnightBlue pointed out that 6¢ is quite wide to be calling it a schisma, which I've also thought about. Maybe ''aberkleisma'' or even ''pentasept comma''?

: I'm not too invested into this comma, but will add my <strike>schisma</strike> 2c after seeing the Discord convo: ''pele comma'' and ''peleisma'' are fine with me, whereas I'm afraid ''argent comma'', while logical, may be confused with the [[argyria]] (which is more of an ''arg''ument for renaming the latter).

: On a side note, 5120/5103 does function like a kleisma for me, particularly because the ratio of the pental kleisma to it is the [[horwell comma]], which is among the staple commas in my 7-limit analysis of edos incl. 53. Because schismic x kleismic product words are among the best ways to make well-tempered 53-note scales, the pental kleisma is a chroma there, and when horwell tempered, it turns into 5120/5103 and is, among other roles, the scale-chroma between the 81/80 and 64/63 steps.

: Meanwhile, the ratio of 5120/5103 to the pental schisma is the [[garischisma]]. So for fans of the latter, which I'm not, it may act like a schisma instead, but that's less likely because the pental schisma flattens the fifth while the garischisma sharpens it, so if anything, the latter and 5120/5103 would be seen as 'negative schismas', which, btw, brings us to the concept of [[counterpyth]].

: Afaik, counterpyth has never been considered under this name without 5120/5103, whereas [[1216/1215]] works well together with other commas that stack slightly sharp fifths, such as the [[wilschisma]] and the [[symbiotic comma]], and the name ''Eratosthenes' comma'' is good, so I disagree with the assignment of the counterpyth family label to any temp with 1216/1215 in sintel's finder. I.e., to me, 5120/5103 is more related to counterpyth than 1216/1215 is. But I can't be sure of my judgment on this without FloraC's opinion. Either way, I don't mind ''counterpyth comma'' for 5120/5103, its 7-limit rank-3 then called counterpyth like its canonical extension to 2.3.5.7.19 already is.

: --[[User:VIxen|VIxen]] ([[User talk:VIxen|talk]]) 23:55, 1 June 2025 (UTC)

:: I'm all for ''argent comma''. The similarity with ''argyria'' isn't high enough to worry me. I'm against ''pele comma'' cuz that would set pele as canon which I don't think we should ever do. For the same reason I'd hesitate to call it ''counterpyth comma''. [[User:FloraC|FloraC]] ([[User talk:FloraC|talk]]) 14:17, 2 June 2025 (UTC)

::: OK, then I settle on ''argent comma'' too. That matches my view of argent fifths as a distinct region that's roughly [65\111, 17\29] and sharp of the olympic / garischismic / symbiotic / wilschismic fifths region that's roughly [55\94, 65\111]. --[[User:VIxen|VIxen]] ([[User talk:VIxen|talk]]) 18:38, 2 June 2025 (UTC)

:::: What about 41edo and 46edo? Those are both notable tunings that temper out the comma and have fifths that fall outside of your *argent* range. -- [[User:Tristanbay|Tristanbay]] ([[User talk:Tristanbay|talk]]) 00:35, 12 June 2025 (UTC)

::::: On my part I include 41edo within the argent range; and there's a case to be made that 46edo and 53edo, while notable, aren't truly representative of the intonation of tempering out 5120/5103. "Argent" strictly speaking refers not to a particular tuning range, anyhow, but to a specific tuning that sets the logarithmic ratio of the perfect fifth to the perfect fourth to be sqrt(2):1, for which one can define bands of tolerance around, but which very closely corresponds to the most accurate tunings that temper out this comma. Perhaps "argentisma" -> argentic, argentismic would be clearer, so as not to imply an RTT interpretation for the term "argent temperament" which is already in use.

::::: Compare this to the intonation of counterpyth, which quite distinctly favors tunings of 3/2 far flatter than the optimum of tempering out 5120/5103 by itself: just 19/15 gives us roughly 1/16-comma hemifamity as opposed to just 15/14, 7/5, or 21/20 which provide 1/5, 1/6, and 1/7-comma tunings. For this reason, I oppose seeing counterpyth as a canonical extension to the 7-limit rank-3 {5120/5103} temperament. -- [[User:Lériendil|Lériendil]] ([[User talk:Lériendil|talk]]) 01:24, 12 June 2025 (UTC)

::::: I did think about making 24\41 the boundary instead, as rank-3 microtemps tend to have flatter fifths than that even if 152fg or 111 support them. My flat end of argent is surely not flatter than 24\41 and not sharper than 41\70. Between those are kwai fifths... that I may consider too damaged indeed on second thought, and so belonging to the "slightly exo" range codenamed argent. [[User:VIxen|VIxen]] ([[User talk:VIxen|talk]]) 20:23, 19 June 2025 (UTC)

: I have a dumb idea. Why not call it the *pell comma* after the Pell sequence of numbers, whose convergent ratio gives the approximate ratio between an octave and a perfect fourth for the optimal tuning of the temperament? [[User:Tristanbay|Tristanbay]] ([[User talk:Tristanbay|talk]]) 20:59, 18 September 2025 (UTC)

:: I think referencing the Pell sequence makes way more sense for a member of the family of commas going 50/49, 289/288, 1682/1681, 9801/9800, etc. The only relation of Pell numbers to 5120/5103 is the edo sequence, which seems rather secondary, as much as I'm a promoter of 239edo. --[[User:Lériendil|Lériendil]] ([[User talk:Lériendil|talk]]) 22:42, 18 September 2025 (UTC)

: I propose the name "interkleisma", since 5120/5103 is the difference between 64/63 and 81/80 (the main formal commas for primes 5 and 7), and is around a kleisma in size.--[[User:Overthink|Overthink]] ([[User talk:Overthink|talk]]) 03:02, 13 February 2026 (UTC)

:: It's a half kleisma in 270edo (and 311edo if you consider other kleismata such as 1029/1024) tho. —[[User:FloraC|FloraC]] ([[User talk:FloraC|talk]]) 09:20, 13 February 2026 (UTC)

::: Your essay on the 13-limit JI space considers 5120/5103~352/351~847/845, 325/324~385/384, 364/363~441/440, 540/539~729/728, and 351/350 as kleismas. Even if it is a half-kleisma in 270edo, the comma is close enough to the rough interval region, and also no single edo should decide the name.--[[User:Overthink|Overthink]] ([[User talk:Overthink|talk]]) 16:58, 13 February 2026 (UTC)

:::: Oh wow, my bad. I'll change them to hemikleismata. —[[User:FloraC|FloraC]] ([[User talk:FloraC|talk]]) 21:39, 13 February 2026 (UTC)

Should we do a poll here? The name was basically pre-maturely changed according to a poll on XA Discord. Besides, we need to decide what to do with the temp's name. —[[User:FloraC|FloraC]] ([[User talk:FloraC|talk]]) 12:51, 22 January 2026 (UTC)

: If enough people want to, then I guess. I like the current name of this comma, and I was thinking of the associated full 7-limit temperament being "argentic" and the 2.3.7/5 subgroup one being "argic". [[User:Tristanbay|Tristanbay]] ([[User talk:Tristanbay|talk]]) 06:12, 27 January 2026 (UTC)

: Why not [[64/63|S8]]/[[81/80|S9]]? Are there many properties of this comma that aren't explained by it being ((8/7)/(9/8)) / ((9/8)/(10/9)) = (64/63) / (81/80) and hence ([[10/7]])/([[9/8]])3? --[[User:Godtone|Godtone]] ([[User talk:Godtone|talk]]) 12:27, 16 February 2026 (UTC)

=== Petition to officialize ''aberschisma'', and change ''hemifamity'' to ''aberschismic'' ===
At this point, ''aberschisma'' and ''aberschismic'' seem like the most widely liked and used names in xenharmonic communities. Thereby I request ''aberschisma'' be set as the permanent, main name for 5120/5103, and ''hemifamity'' be officially changed to ''aberschismic''.

Gammic family

Lériendil: the 7-limit header should still be there because it has subgroup temps under it

{{Technical data page}}
The [[Carlos Gamma]] rank-1 temperament divides 3/2 into 20 equal parts, 11 of which give a 5/4. This is closely related to the rank-2 microtemperament tempering out {{monzo| -29 -11 20 }}, the [[gammic comma]]. This temperament, '''gammic''', takes 11 [[generator]] steps to reach 5/4, and 20 to reach 3/2. The generator in question is 1990656/1953125 = {{monzo| 13 5 -9 }}, which when suitably tempered is very close to 5/171 octaves, which makes for an ideal gammic tuning. As a 5-limit temperament supported by [[171edo]], [[Schismatic family|schismatic]] temperament makes for a natural comparison. Schismic, tempering out {{monzo| -15 8 1 }}, the [[schisma]], is plainly much less complex than gammic, but people seeking the exotic might prefer gammic even so. The 34-note mos is interesting, being a 1L 33s refinement of the [[34edo]] tuning. Of course gammic can be tuned to 34, which makes the two equivalent, and would rather remove the point of Carlos Gamma if used for it.

Because 171 is such a strong [[7-limit]] system, it is natural to extend gammic to the 7-limit. This we may do by adding [[4375/4374]] to the comma list. 96 gammic generators finally reach 7, which is a long way to go compared to the 39 generator steps of pontiac. If someone wants to make the trip, a 103-note mos is possible.

== Neptune ==
A more interesting extension is to neptune, which divides an octave plus a gammic generator in half, to get a 10/7 generator. Neptune adds [[2401/2400]] to the gammic comma, and may be described as the 68&171 temperament. The generator chain goes merrily on, stacking one 10/7 over another, until after eighteen generator steps 6/5 (up nine octaves) is reached. Then in succession we get 12/7, the neutral third, 7/4 and 5/4. Two neutral thirds then gives a fifth, and these intervals with their inverses are the full set of septimal consonances. [[171edo]] makes a good tuning, and we can also choose to make any of the consonances besides 7/5 and 10/7 just, including the fifth, which gives a tuning extending [[Carlos Gamma]].

Adding 385/384 or 1375/1372 to the list of commas allows for an extension to the [[11-limit]], where (7/5)3 equates to 11/4.

[[Gene Ward Smith]] once described [https://yahootuninggroupsultimatebackup.github.io/tuning-math/topicId_6001.html neptune as an analog of miracle].

==== 2.3.5.7.17.31 subgroup ====
Since neptune splits the interval of [[5/3]] into two, we can accurately map each part to [[40/31]]~[[31/24]] by tempering out [[961/960]] (S31). This is especially natural, as combined with tempering out 1225/1224 (S35) and 24576/24565 (S16/S17), we can map (17/16)2 (6 gammic generators) to [[35/31]]. This also gives us its complement with respect to [[5/4]], the interval of 5 gammic generators representing a quarter of a perfect fifth, as [[31/28]].

Subgroup temperaments

Lériendil: /* Tridecimal guanyintet */

{{Technical data page}}
A '''subgroup temperament''' is a regular temperament defined on a [[just intonation subgroup]] that is not a full ''p''-limit group.

For temperaments that omit various prime harmonics, see:
* [[No-thirteens subgroup temperaments]]
* [[No-elevens subgroup temperaments]]
* [[No-sevens subgroup temperaments]]
* [[No-fives subgroup temperaments]]
* [[No-threes subgroup temperaments]]
* [[No-twos subgroup temperaments]] (additionally, [[Catalog of 3.5.7 subgroup rank two temperaments]]).

Below are some temperaments for composite subgroups and fractional subgroups. Obviously, no attempt has been made at completeness; attention is focused on subgroups containing interesting chords. The reader may also want to consult the page on [[Chromatic pairs]].

=== Commatose ===
Commatose is a [[Dual-fifth temperaments|dual-fifth temperament]] which uses the Pythagorean comma as a generator. It was developed by [[Eliora]] to highlight the near-perfect expression of 9/8 by [[1789edo]], while at the same time the fact that it completely misses 3/2. It is described as the 460 & 1329 temperament. In the 13-limit extension 24 generators are equal to [[~]][[13/9]].

Daemotertiaschis is produced by taking every other generator of tertiaschis, and the subgroup is chosen so it tempers out exactly the same commas. It is notable due to offering a [[7L 4s|daemotonic 7L 4s]] scale of reasonable hardness, which is notoriously difficult to approximate with simple JI or RTT methods.

=== Demon ===
Demon is a temperament which equates 3 [[11/9]] with [[16/9]], or equivalently 3 [[18/11]] with [[9/8]], tempering out [[1331/1296]]. This results in [[11/9]] being tuned flat to a supraminor third, and [[27/22]] being tuned sharp to a submajor third. It was discovered by [[User:CompactStar|CompactStar]] while searching for temperaments assosciated with the [[7L 4s]] ("daemotonic") MOS, known for its lack of representation of simple temperaments. The optimal tuning for demon temperament is near the basic tuning of 7L 4s (13\18), and indeed [[18edo]] supports demon temperament.

=== Fourwar ===
The 23-limit version of Fourwar was created first, as an attempt to approximate subgroup 4.6.5.7.11.13.17.19.23 as accurately as possible using 25 to 35 notes per equave. Then the lower limit versions were created by simply extrapolating the temperament downwards.

Fourwar is named after the closely related [[hemiwar]] temperament.

== 8.9.7 subgroup ==
=== Sixscared ===
Sixscared is a tuning which still maintains some consonance, while eviscerating the rules of conventional 12-tone harmony. The familiar major, minor and perfect intervals are nowhere to be found, and octaves are far and few between, so the seventh harmonic becomes the backbone of harmony. Approximating the harmonics 7, 8, 9, Sixscared is named for the classic dad joke: "Why was six scared? Because seven ate nine."

=== Fiventeen ===
Fiventeen tempers out [[136/135]] ({{monzo| 3 -3 1 }}) in 2.3.17/5. It equates [[17/15]] with [[9/8]], so it implies a [[supersoft]] [[pentic]] [[pentad]] of [[~]]30:34:40:45:51. [[17edo]] makes a good tuning especially for its size, which gives a [[supersoft]] pentic scale corresponding approximately to a just [[20/17]] tuning, although [[80edo]] might be preferred for an approximately just [[51/40]] to optimize plausibility slightly more, and [[97edo]] (= 80 + 17) and [[114edo]] (= 97 + 17) do even better in striking a balance between 80edo's more stable tuning and that having 20/17 more accurate (as in 17edo) is useful because of the more convincing suggestion of the two 15:17:20 chords present in the fiventeen pentad. The same is true of the related rank-3 temperament diatic, for which the [[optimal ET sequence]] is much more characteristic of optimized tunings, finding [[34edo]], then [[80edo]], then [[114edo]] (= 34 + 80) and even [[194edo|194bc-edo]] (= 80 + 114), though because of its focus on primes 5 and 17 it misses 97edo as a tuning, and slightly less optimized though still interesting [[63edo]] and [[143edo]] (= 63 + 80) tunings are found in the optimal ET sequence for fiventeen.

Subgroup temperaments

Lériendil: added tridecimal guanyintet

{{Technical data page}}
A '''subgroup temperament''' is a regular temperament defined on a [[just intonation subgroup]] that is not a full ''p''-limit group.

For temperaments that omit various prime harmonics, see:
* [[No-thirteens subgroup temperaments]]
* [[No-elevens subgroup temperaments]]
* [[No-sevens subgroup temperaments]]
* [[No-fives subgroup temperaments]]
* [[No-threes subgroup temperaments]]
* [[No-twos subgroup temperaments]] (additionally, [[Catalog of 3.5.7 subgroup rank two temperaments]]).

Below are some temperaments for composite subgroups and fractional subgroups. Obviously, no attempt has been made at completeness; attention is focused on subgroups containing interesting chords. The reader may also want to consult the page on [[Chromatic pairs]].

=== Commatose ===
Commatose is a [[Dual-fifth temperaments|dual-fifth temperament]] which uses the Pythagorean comma as a generator.

It is described as the 460 & 1329 temperament. In the 13-limit extension 24 generators are equal to [[~]][[13/9]].

== 2.9.11 subgroup ==
=== Demon ===
Demon is a temperament which equates 3 [[11/9]] with [[16/9]], or equivalently 3 [[18/11]] with [[9/8]], tempering out [[1331/1296]]. This results in [[11/9]] being tuned flat to a supraminor third, and [[27/22]] being tuned sharp to a submajor third. It was discovered by [[User:CompactStar|CompactStar]] while searching for temperaments assosciated with the [[7L 4s]] ("daemotonic") MOS, known for its lack of representation of simple temperaments. The optimal tuning for demon temperament is near the basic tuning of 7L 4s (13\18), and indeed [[18edo]] supports demon temperament.

=== Fourwar ===
The 23-limit version of Fourwar was created first, as an attempt to approximate subgroup 4.6.5.7.11.13.17.19.23 as accurately as possible using 25 to 35 notes per equave. Then the lower limit versions were created by simply extrapolating the temperament downwards.

Fourwar is named after the closely related [[hemiwar]] temperament.

== 8.9.7 subgroup ==
=== Sixscared ===
Sixscared is a tuning which still maintains some consonance, while eviscerating the rules of conventional 12-tone harmony. The familiar major, minor and perfect intervals are nowhere to be found, and octaves are far and few between, so the seventh harmonic becomes the backbone of harmony. Approximating the harmonics 7, 8, 9, Sixscared is named for the classic dad joke: "Why was six scared? Because seven ate nine."

=== Fiventeen ===
Fiventeen tempers out [[136/135]] ({{monzo| 3 -3 1 }}) in 2.3.17/5. It equates [[17/15]] with [[9/8]], so it implies a [[supersoft]] [[pentic]] [[pentad]] of [[~]]30:34:40:45:51. [[17edo]] makes a good tuning especially for its size, which gives a [[supersoft]] pentic scale corresponding approximately to a just [[20/17]] tuning, although [[80edo]] might be preferred for an approximately just [[51/40]] to optimize plausibility slightly more, and [[97edo]] (= 80 + 17) and [[114edo]] (= 97 + 17) do even better in striking a balance between 80edo's more stable tuning and that having 20/17 more accurate (as in 17edo) is useful because of the more convincing suggestion of the two 15:17:20 chords present in the fiventeen pentad. The same is true of the related rank-3 temperament diatic, for which the [[optimal ET sequence]] is much more characteristic of optimized tunings, finding [[34edo]], then [[80edo]], then [[114edo]] (= 34 + 80) and even [[194edo|194bc-edo]] (= 80 + 114), though because of its focus on primes 5 and 17 it misses 97edo as a tuning, and slightly less optimized though still interesting [[63edo]] and [[143edo]] (= 63 + 80) tunings are found in the optimal ET sequence for fiventeen.

Subgroup temperaments

Lériendil: decanonicalized "edson" for hemifamity

{{Technical data page}}
A '''subgroup temperament''' is a regular temperament defined on a [[just intonation subgroup]] that is not a full ''p''-limit group.

For temperaments that omit various prime harmonics, see:
* [[No-thirteens subgroup temperaments]]
* [[No-elevens subgroup temperaments]]
* [[No-sevens subgroup temperaments]]
* [[No-fives subgroup temperaments]]
* [[No-threes subgroup temperaments]]
* [[No-twos subgroup temperaments]] (additionally, [[Catalog of 3.5.7 subgroup rank two temperaments]]).

Below are some temperaments for composite subgroups and fractional subgroups. Obviously, no attempt has been made at completeness; attention is focused on subgroups containing interesting chords. The reader may also want to consult the page on [[Chromatic pairs]].

=== Commatose ===
Commatose is a [[Dual-fifth temperaments|dual-fifth temperament]] which uses the Pythagorean comma as a generator. It was developed by [[Eliora]] to highlight the near-perfect expression of 9/8 by [[1789edo]], while at the same time the fact that it completely misses 3/2. It is described as the 460 & 1329 temperament. In the 13-limit extension 24 generators are equal to [[~]][[13/9]].

Daemotertiaschis is produced by taking every other generator of tertiaschis, and the subgroup is chosen so it tempers out exactly the same commas. It is notable due to offering a [[7L 4s|daemotonic 7L 4s]] scale of reasonable hardness, which is notoriously difficult to approximate with simple JI or RTT methods.

== 2.9.11 subgroup ==
=== Demon ===
Demon is a temperament which equates 3 [[11/9]] with [[16/9]], or equivalently 3 [[18/11]] with [[9/8]], tempering out [[1331/1296]]. This results in [[11/9]] being tuned flat to a supraminor third, and [[27/22]] being tuned sharp to a submajor third. It was discovered by [[User:CompactStar|CompactStar]] while searching for temperaments assosciated with the [[7L 4s]] ("daemotonic") MOS, known for its lack of representation of simple temperaments. The optimal tuning for demon temperament is near the basic tuning of 7L 4s (13\18), and indeed [[18edo]] supports demon temperament.

=== Fourwar ===
The 23-limit version of Fourwar was created first, as an attempt to approximate subgroup 4.6.5.7.11.13.17.19.23 as accurately as possible using 25 to 35 notes per equave. Then the lower limit versions were created by simply extrapolating the temperament downwards.

Fourwar is named after the closely related [[hemiwar]] temperament.

== 8.9.7 subgroup ==
=== Sixscared ===
Sixscared is a tuning which still maintains some consonance, while eviscerating the rules of conventional 12-tone harmony. The familiar major, minor and perfect intervals are nowhere to be found, and octaves are far and few between, so the seventh harmonic becomes the backbone of harmony. Approximating the harmonics 7, 8, 9, Sixscared is named for the classic dad joke: "Why was six scared? Because seven ate nine."

== 2.….17/5.… subgroups ==
=== Fiventeen ===
Fiventeen tempers out [[136/135]] ({{monzo| 3 -3 1 }}) in 2.3.17/5. It equates [[17/15]] with [[9/8]], so it implies a [[supersoft]] [[pentic]] [[pentad]] of [[~]]30:34:40:45:51. [[17edo]] makes a good tuning especially for its size, which gives a [[supersoft]] pentic scale corresponding approximately to a just [[20/17]] tuning, although [[80edo]] might be preferred for an approximately just [[51/40]] to optimize plausibility slightly more, and [[97edo]] (= 80 + 17) and [[114edo]] (= 97 + 17) do even better in striking a balance between 80edo's more stable tuning and that having 20/17 more accurate (as in 17edo) is useful because of the more convincing suggestion of the two 15:17:20 chords present in the fiventeen pentad. The same is true of the related rank-3 temperament diatic, for which the [[optimal ET sequence]] is much more characteristic of optimized tunings, finding [[34edo]], then [[80edo]], then [[114edo]] (= 34 + 80) and even [[194edo|194bc-edo]] (= 80 + 114), though because of its focus on primes 5 and 17 it misses 97edo as a tuning, and slightly less optimized though still interesting [[63edo]] and [[143edo]] (= 63 + 80) tunings are found in the optimal ET sequence for fiventeen.

Lériendil: replaced quasitemp with superkleismic, since it's generated by 6/5 like myna and demonstrates the keemic equivalence better; also I believe it to be more known than quasitemp

'''Myna''' is a [[rank-2]] [[regular temperament|temperament]] that is [[generator|generated]] by a flattened minor third of [[~]][[6/5]], so that seven generators reach [[7/4]], nine reach [[5/4]] and ten reach [[3/2]]. It can be thought of in terms of a series of equidistances between thirds, that is, making [[8/7]]–[[7/6]]–6/5–[[49/40]]–[[5/4]]–[[9/7]]–[[21/16]] all equidistant (the distances between which are [[36/35]], [[49/48]], and [[50/49]]), or otherwise tuning the pental thirds outwards so that the chroma between them ([[25/24]]) is twice the size of the interval between the pental and septimal thirds, 36/35. This is one of two major options for how the thirds are organized in [[edo]]s of medium size – the other one being [[keemic temperaments]], such as [[superkleismic]], where the gap between 6/5 and 5/4 is compressed to equal that between 7/6 and 6/5 instead of widened to equal twice it. In either case, by tempering the septimal dieses together, there is an exact neutral third in between 6/5 and 5/4. [[11-limit]] myna then arises from equating this neutral third to [[11/9]] and 13-limit myna adds the interpretation of [[16/13]] to it as well.

[[27edo|27e-edo]] and [[31edo]] represent natural endpoints of myna's tuning range, and 27 + 31 = [[58edo]] and 58 + 31 = [[89edo]] are very good tunings. In terms of [[commas]], the most characteristic comma that myna [[tempering out|tempers out]] is [[126/125]], the starling comma, so that two generators reach [[10/7]] and four reach the distinctive 36/35~50/49 chroma. Additionally, [[1728/1715]] ([[S-expression|S6/S7]]), the orwellisma, is tempered out to equate 36/35 with 49/48, and so is [[2401/2400]], the breedsma, to equate 49/48 and 50/49 (and find a neutral third at 49/40~60/49). In the 11-limit, [[176/175]], [[243/242]], [[441/440]], and [[540/539]] are tempered out; in the 13-limit, [[144/143]] and [[352/351]] are additionally tempered out.

Note: "myna" is pronounced /'maɪnə/, like {{w|myna|the bird}}, but is also as a pun on "minor".

Ed5/3

Lériendil:

The '''equal division of 5/3''' ('''ed5/3''') is a [[tuning]] obtained by dividing the [[5/3|just major sixth (5/3)]] into a number of [[equal]] steps.

== Properties ==
Division of 5/3 into equal parts does not necessarily imply directly using this interval as an [[equivalence]]. Many, though not all, ed5/3 scales have a perceptually important [[Pseudo-octave|false octave]], with various degrees of accuracy.

5/3 is the most consonant interval in between 3/2 and 2/1, so this suggests it could be useful either as an equivalence, or as just an important structural feature.

[[Joseph Ruhf]] suggested the use of the 6:7:8:(10) chord as the fundamental complete sonority in a very similar way to the 4:5:6:(8) chord in meantone as a way to evoke 5/3-equivalence. Though it could also be used just as a useful sonority, even without equivalence. Whereas in meantone it takes four 3/2 to get to 5/1, here it takes four 4/3 to get to 8/7 (tempering out the comma 225/224). So, doing this yields 7-, 9-, and 16-note [[mos]] either way, the 16-note mos being 7L 9s. While the notes are rather closer together, the scheme is uncannily similar to meantone. "Microdiatonic" might be a good term for it (even better than for [[edf]]s as the generator it uses is an excellent fit for heptatonic mos) though it is, technically speaking, micro-[[7L 2s|armotonic]].

If we instead opt to continue using 4:5:6 as the fundamental sonority, then it will take three 3/2 to get to 5/4, resulting in [[Blackcomb]] temperament that tempers out the comma 250/243. This yields mos scales of 4, 5, 6, 11, 16, and 21 notes. Although, it should be noted that doing this will often create a pseudo-octave unlike the 6:7:8 approach.

ED5/3 tuning systems that accurately represent the intervals 5/4 and 4/3 include: [[7ed5/3]] (7.30 cent error), [[9ed5/3]] (6.73 cent error), and [[16ed5/3]] (0.59 cent error).

[[7ed5/3]], [[9ed5/3]], and [[16ed5/3]] are to the [[Ed5/3|division of 5/3]] what [[5edo]], [[7edo]], and [[12edo]] are to the [[EDO|division of 2/1]].

'''24192/24167''', the '''navicular comma''' is a no-fives [[13-limit]] comma that is the difference between three [[13/12]]s and one [[14/11]]. It is tempered out in some EDOs such as [[17edo|17]], [[26edo|26]], [[77edo|77]], [[94edo|94]], [[104edo|104]], [[130edo|130]], [[207edo|207]] and [[224edo|224]].

85edo

Lériendil: /* Theory */

{{Infobox ET}}
{{ED intro}}

== Theory ==
Since 85 {{=}} 5 × 17, 85edo shares the same 3.9-cent-sharp fifth as [[17edo|17]], [[34edo|34]], and [[68edo|68]]. 3/1 is therefore divisible into 5, and the [[patent val]] correspondingly supports [[magic]], [[tempering out]] [[3125/3072]] in the [[5-limit]] and [[225/224]], [[245/243]], and [[875/864]] in the [[7-limit]]. It tempers out [[100/99]] and [[385/384]] in the [[11-limit]], supporting 11-limit magic, and [[847/845]], [[1188/1183]], and [[1575/1573]] in the 13-limit. It provides the [[optimal patent val]] for the 13-limit 36ce & 49f temperament tempering out 100/99, 540/539, 847/845 and 1575/1573. The 85c val, with a very sharp 5/4 of 395.3{{c}}, supports 7-limit [[myna]].

=== Odd harmonics ===
{{Harmonics in equal|85}}

=== Subsets and supersets ===
85edo contains [[5edo]] and [[17edo]] as subsets. [[255edo]], which triples it, is a notable tuning.

Valinorsmic clan

2026-05-13T21:55:27Z

Lériendil: /* Valinor */

{{Technical data page}}
The '''valinorsmic clan''' of [[rank-3 temperament|rank-3]] [[regular temperament|temperaments]] [[tempering out|tempers out]] the valinorsma, [[176/175]], which equates [[48/35]] with [[15/11]] (rather than [[11/8]], which is what the keenanisma [[385/384]] does).

For the rank-4 valinorsmic temperament, see [[Rank-4 temperament #Valinorsmic (176/175)]].

== Valinor ==
''Valinor'' is the 2.5.7.11 temperament defined by tempering out 176/175. When extending to prime 13, two strong extensions are considerable: ''valimar'' and ''valarin''; these intersect in [[Hemimean clan #tridecimal didacus|tridecimal didacus]].

[[Badness]] (Sintel): 0.0793

=== Valimar ===
This extension to the no-threes 13-limit is motivated by extending the valinorsmic chain of 5/4s, where two form 11/7, so that four form 16/13. This logic is supported by rank-2s such as tridecimal didacus and the 13-limit [[magus]]/[[amigo]] extensions, as well as [[Orwell extensions|winston]] and [[Valentine extensions|valentino]]. This is also natural considering [[S-expression]]s, noting that 176/175 = S8/S10 is (nontrivially) equivalent to (S11*S12)/(S14*S15), and this extension tempers out S11/S14 = [[1573/1568]], and S12/S15 = [[3584/3575]]. It remains well-tuned in ETs with optimal valinorsmic 5/4s (such as [[37edo|37]], [[40edo|40]], and [[43edo|43]]).

{{Optimal ET sequence|legend=1| TBD }}

[[Badness]] (Sintel): 0.336

=== Valarin ===
This extension equates two, ideally slightly flattened, [[8/7]]s to [[13/10]], which is also natural given valinorsmic's tuning tendency towards sharpening [[7/4]]. This extension is supported by rank-2 temperaments including tridecimal didacus, [[Orwell extensions|tridecimal orwell]], [[Valentine extensions|lupercalia]] (an extension of [[valentine]]), and [[llywelyn]].

=== Overview to extensions ===
The second comma in the comma list determines how we extend the no-3 subgroup temperament to include the harmonic 3. Zeus adds [[121/120]] as well as 385/384, and shares the same lattice structure as no-3 valinorsmic. Varda, adds [[896/891]], slicing the first generator in two with a semi-octave period. Nickel adds [[36/35]] as well as [[45/44]]. Ares adds [[64/63]]. Minerva adds [[99/98]]. Thrush adds [[126/125]]. These slice the last generator in two. Guanyin adds [[540/539]], slicing the first generator in three. Manwe adds [[1331/1323]], slicing the last generator in three. Clio adds [[81/80]], slicing the first generator in four. Lono adds [[5120/5103]], slicing the last generator in six. Mandos adds [[243/242]]. Shrusus adds [[245/243]]. These slice the last generator in five. Ulmo adds [[2200/2187]], slicing the last generator in seven. Finally, draco adds [[19683/19600]], slicing the last generator in nine. Most of these have natural extensions to the [[13-limit]] via tempering out both [[351/350]] and [[352/351]].

Valinorsmic clan

2026-05-13T21:42:53Z

Lériendil: added description

{{Technical data page}}
The '''valinorsmic clan''' of [[rank-3 temperament|rank-3]] [[regular temperament|temperaments]] [[tempering out|tempers out]] the valinorsma, [[176/175]], which equates a stack of two [[5/4]]s with [[11/7]]; ideally, 5/4 is slightly sharpened to make this equivalence. The valinorsma can also be seen as equating [[35/32]] with [[11/10]] (rather than [[12/11]], which is what the keenanisma [[385/384]] does).

For the rank-4 valinorsmic temperament, see [[Rank-4 temperament #Valinorsmic (176/175)]].

== Valinor ==
''Valinor'' is the 2.5.7.11 temperament defined by tempering out 176/175.

=== Overview to extensions ===
The second comma in the comma list determines how we extend the no-3 subgroup temperament to include the harmonic 3. Zeus adds [[121/120]] as well as 385/384, and shares the same lattice structure as no-3 valinorsmic. Varda, adds [[896/891]], slicing the first generator in two with a semi-octave period. Nickel adds [[36/35]] as well as [[45/44]]. Ares adds [[64/63]]. Minerva adds [[99/98]]. Thrush adds [[126/125]]. These slice the last generator in two. Guanyin adds [[540/539]], slicing the first generator in three. Manwe adds [[1331/1323]], slicing the last generator in three. Clio adds [[81/80]], slicing the first generator in four. Lono adds [[5120/5103]], slicing the last generator in six. Mandos adds [[243/242]]. Shrusus adds [[245/243]]. These slice the last generator in five. Ulmo adds [[2200/2187]], slicing the last generator in seven. Finally, draco adds [[19683/19600]], slicing the last generator in nine. Most of these have natural extensions to the [[13-limit]] via tempering out both [[351/350]] and [[352/351]].

{{Infobox ET}}
{{ED intro}} The chord [0 5 9]\15ed7/3, closely resembling the 5-limit major triad of [[15edo]], is a close approximation in this tuning system to [[3:4:5]]. A potentially tempered 15ed7/3 chain with octaves as the equivalence results in [[passion]] temperament, with 3:4:5:7 located on the same position that it is in 15ed7/3.

{{todo|inline=1|cleanup|explain edonoi|text=Most people do not think 7/3 sounds like an equivalence, so there must be some other reason why people are dividing it — some property ''other than'' equivalence that makes people want to divide it. Please add to this page an explanation of what that reason is... The page also needs a general overall cleanup.}}

The '''equal division of 7/3''' ('''ed7/3''') is a [[tuning]] obtained by dividing the [[7/3|septimal minor tenth (7/3)]] in a certain number of [[equal]] steps.

== Applications ==
Division of 7/3 into equal parts does not necessarily imply directly using this interval as an [[equivalence]]. Many, though not all, ed7/3 scales have a perceptually important [[Pseudo-octave|false octave]], with various degrees of accuracy.

The structural utility of 7/3 (or another tenth) is apparent by being the absolute widest range most generally used in popular songs{{citation needed}} (and even the range of a {{w|Dastg%C4%81h-e_M%C4%81hur|dastgah}}{{citation needed}}).

== Chords and harmonies ==
{{main|Pseudo-traditional harmonic functions of enneatonic scale degrees}}
[[:Category:9-tone scales|Enneatonic scale]]s, especially those equivalent at 7/3, can sensibly take [[tetrad]]s as the fundamental complete sonorities of a pseudo-traditional functional harmony due to their seventh degree being as structurally important as it is. Many, though not all, of these scales have a perceptually important [[Pseudo-octave|pseudo (false) octave]], with various degrees of accuracy.

Incidentally, one way to treat 7/3 as an equivalence is the use of the 3:4:5:(7) chord as the fundamental complete sonority in a very similar way to the 4:5:6:(8) chord in [[meantone]]. Whereas in meantone it takes four [[3/2]] to get to [[5/1]], here it takes two [[28/15]] to get to [[7/2]] (tempering out the comma [[225/224]]). So, doing this yields 15-, 19-, and 34-note [[mos]] 2/1 apart. While the notes are rather farther apart, the scheme is uncannily similar to meantone. [[Joseph Ruhf]] named this scheme "macrobichromatic".

'''Ed7/3''' means '''Division of the septimal minor tenth ([[7/3]]) into n equal parts'''.

== Properties ==
Division of 7/3 into equal parts can be conceived of as to directly use this interval as an equivalence, or not. The question of [[equivalence]] has not even been posed yet. The utility of 7:3 (or another tenth) as a base though, is apparent by being the absolute widest range most generally used in popular songs (and even the range of a [https://en.wikipedia.org/wiki/Dastg%C4%81h-e_M%C4%81hur dastgah]) as well as a fairly trivial point to split the difference between the octave and the tritave (which is why I have named the region of intervals between 6 and 7 degrees of 5edo the "Middletown valley", the proper Middletown temperament family being based on an enneatonic scale generated by a third or a fifth optionally with a period of a wolf fourth at most 560 cents wide) and, as is the twelfth, an alternative interval where [[wikipedia:Inversion_(music)#Counterpoint|invertible counterpoint]] has classically occurred. Incidentally [[Pseudo-traditional harmonic functions of enneatonic scale_degrees|enneatonic scales]], especially those equivalent at e. g. 7:3, can sensibly take tetrads as the fundamental complete sonorities of a pseudo-traditional functional harmony due to their seventh degree being as structrally important as it is. Many, though not all, of these scales have a perceptually important pseudo (false) octave, with various degrees of accuracy.

Incidentally, one way to treat 7/3 as an equivalence is the use of the 3:4:5:(7) chord as the fundamental complete sonority in a very similar way to the 4:5:6:(8) chord in meantone. Whereas in meantone it takes four 3/2 to get to [[5/1]], here it takes two [[28/15]] to get to 7/2 (tempering out the comma 225/224). So, doing this yields 15, 19, and 34 note MOS 2/1 apart. While the notes are rather farther apart, the scheme is uncannily similar to meantone. "Macrobichromatic" might be a practically perfect term for it if it hasn't been named yet.

The branches of the Middletown family are named thus:

* 3&6: Tritetrachordal
* 4&5: Montrose (between 5\4edo and 4\3edo in particular, MOS generated by [pseudo] octaves belong to this branch)
* 2&7: Terra Rubra

The family of interlaced octatonic scale based temperaments in the "Middletown valley" is called Vesuvius (i. e. the volcano east of Naples).

The Middlebury temperament falls in the "Middletown valley", but its enneatonic scales are "generator-remainder".

The temperaments neighboring Middletown proper are named thus:

* 5&6: Rosablanca
* 4&7: Saptimpun (10 1/2)
* 5&7: 8bittone (Old Middetown)

Sort of unsurprisingly, though not so evidently, the pyrite tuning of edXs will turn out to divide a barely mistuned 5:2 of alomst exactly 45\34edo.

Lériendil: /* Deletion, again */

Anybody know what this is about? I propose we delete it, or else someone should really break it down and explain what this is. [[User:Keenan Pepper|Keenan Pepper]] ([[User talk:Keenan Pepper|talk]]) 23:35, 20 September 2018 (UTC)

== Request for deletion ==

Since the comment above was never adressed, I will just say we rewrite this current page (I'm willing to take a shot), and delete these:
* [[8edX]]
* [[9edX]]
* [[15edX]]
* [[16edX]]
* [[17edX]]
* [[19edX]]

As they are all nonsensical tables with no practical use. If someone wants to replace them with a simple templated table that generates the intervals (as on the EDO pages) that'd be fine too.

EDIT: signed -- [[User:Sintel|Sintel]] ([[User talk:Sintel|talk]]) 21:16, 19 January 2022 (UTC)

: I do not like all these mentioned tables in any way, and for me personally their value is not evident, at all am against trying to prove hypotheses by handmade tables. But since users have spent time on these tables, I am against simply deleting the pages in question. I would rather move them to the main editor's username space, where they will have time to elaborate them so that they are ready for the article namespace from the other users' point of view as well. I am doing the necessary work for this right now... --[[User:Xenwolf|Xenwolf]] ([[User talk:Xenwolf|talk]]) 13:43, 26 February 2022 (UTC)

== Deletion, again ==
Almost all ed7/3 pages are completely devoid of information, and this page itself is filled with what is clearly nonsense.
Since MMTM has been banned, and apparently nobody cares about any of this, I think we should revisit this.

– [[User:Sintel|Sintel🎏]] ([[User_talk:Sintel|talk]]) 00:36, 13 May 2026 (UTC)

: What about ed5/3? —[[User:FloraC|FloraC]] ([[User talk:FloraC|talk]]) 09:27, 13 May 2026 (UTC)

:: Probably same story. Honestly I think we should be somewhat careful in applying [[XW:NG]] retroactively, but the part about:
:::Entries consisting solely of automatically generated content (e.g. interval tables, infoboxes) without context or explanation can be deleted without relocation.
:: Can be enforced without much issues, since we don't lose anything.
:: – [[User:Sintel|Sintel🎏]] ([[User_talk:Sintel|talk]])

::: I'm in support of deleting most of the ed5/3 and ed7/3 pages based on that guideline. I think this page itself should be considered under a different standard, and we'll have a clearer idea if we clean it up from MMTMisms (like "Middletown Valley" etc.).

'''Mothra''', also known as '''cynder''', is a temperament of the [[7-limit]] that is a strong extension to [[slendric]], which is defined by splitting a perfect fifth representing [[3/2]] into three intervals of [[8/7]], tempering out [[1029/1024]]. The fifth of mothra is flattened to a [[meantone]] fifth, so that it reaches [[5/4]] when stacked four times and [[81/80]] is tempered out, unlike that of the other slendric extension [[rodan]], which is sharpened from just. This has the effect of bringing the generator 8/7 considerably closer to just, and also allowing [[MOS scale]]s of mothra to be more melodically usable than those of other forms of slendric, as the structurally-pervasive small step known as the [[quark]] (the residue between the octave and 5 generators, representing [[49/48]], [[64/63]], and in mothra also [[36/35]]) is larger here. [[EDOs]] that support mothra include [[26edo]], [[31edo]], and [[36edo]], and 31 is a particularly good tuning.

In the [[11-limit]], two extensions are of note: undecimal mothra (26 & 31), which tempers out [[99/98]], [[385/384]] and [[441/440]] to find the 11th harmonic at 8 generators down, and mosura (31 & 36), which tempers out [[176/175]] to find the 11th harmonic at 23 generators up. These two mappings merge at 31edo, which is therefore a uniquely suitable tuning for 11-limit mothra.

In higher limits, one may note that the two-generator interval closely approximates [[17/13]], and that the six-generator interval - the meantone whole tone of [[9/8]][[~]][[10/9]], approximates [[19/17]] - so that the 13:17:19 chord is well-represented; it is worth noting also that this chord is entirely included within the subtemperament obtained from taking every other generator of mothra, which is [[A-team]] (the crawma, [[83521/83486]], is the relevant comma tempered out here). This can be combined with the canonical mapping of 13 for each undecimal extension, which tempers out [[144/143]], to provide a natural route to the [[19-limit]].

For technical data, see [[Gamelismic clan #Mothra]].

== Intervals ==
As a strong extension of slendric, mothra's intervals can be expressed using the same system of extended diatonic interval naming [[Slendric #Interval categories|used for slendric]]. It is particularly convenient to use diatonic conventions for mothra, because its chain of fifths is meantone, and therefore 5/4 is simply read as a major third.

In the following table, odd harmonics and subharmonics 1–21 are labeled in '''bold'''.

'''456/455''', the '''abnobisma''', is a [[19-limit]] [[Superparticular ratio|superparticular comma]] of about 3.8 [[cent]]s. It is the amount by which a stack consisting of [[7/6]] and [[20/19]] falls short of [[16/13]], and the difference between [[35/24]] = (7/6)([[5/4]]) and [[19/13]]. By tempering it out is defined the '''abnobismic temperament''', which enables the [[abnobismic chords]].

== Etymology ==
The name ''abnobisma'' was named by [[User:Xenllium|Xenllium]] in 2023. It refers to [[Wikipedia:456 Abnoba|456 Abnoba]], the asteroid. Which in turn was named after a Celtic goddess.

'''90/77''', the swetismic subminor third, is 540/539 (3.2 cents) sharp of [[7/6]]. It arises in 11-limit scales as the interval between 11/10 and 9/7, 7/6 and 15/11, 11/9 and 10/7, and their inversions.

Additionally, it is [[385/384]] (4.5 cents) flat of [[75/64]], the classic augmented second.

It is very closely approximated in [[40edo]], which contextualizes it further as the product of [[15/14]] and [[12/11]].

Lériendil: /* Minimax tunings */

== Minimax tunings ==
Although I'd like to have any excuse for the 7th harmonic to be more in tune, I don't think it makes much sense to call the tuning with eigenmonzo 7/6 the "7-odd-limit minimax".

If I understand correctly, this generator size was chosen because it balances 10/7, which is 17.5 cents flat, with 6/5, which is 17.5 cents sharp, but in pajara 10/7 is always 17.5 cents flat, so there is no point in balancing it. With the same reasoning you can say that the tuning where 5/4 is eigenmonzo, with a fifth of 706.843 cents, is the 7-odd limit minimax, because it balances the two worst intervals – 10/7 with 7/4, which are both, again, 17.5 cents sharp/flat respectively. If you take the term "minimax" literally, i.e. "The tuning in which the maximal error of any consonance is minimal", you get that any tuning between them is also a minimax, because in all of them the maximal error is 17.5 cents – that of 10/7.

I suggest labeling the tuning with eigenminzo 48/35 the 7-odd limit minimax, because that's where 6/5 and 8/7 are balanced. That's also what you get if you take the minimum of the [https://en.wikipedia.org/wiki/Norm_(mathematics)#p-norm p-norm (Wikipedia)] of the errors when p approaches infinity. I haven't checked but some other odd-limit minimax tunings may be changed too. [[User:Roeesi|Roeesi]] ([[User talk:Roeesi|talk]]) 13:56, 16 October 2022 (UTC)

Different from what? Is this talking about Pajara[10] or Pajara[12]? Afaik pajara doesn't have an exact hemifourth.

> A unique feature of pajara is [1–6/5–3/2–12/7] as an essentially tempered alteration to [1–5/4–3/2–7/4] where both the third and the harmonic seventh are flattened by a chroma.

Isn't it a feature of all jubilismic temperaments? Also "essentially tempered alteration" doesn't make sense to me.

: Pajara has "~900-1000c" as an interval category. The meaning of "essentially tempered alteration" is clear. Flattening these two intervals by the same amount cannot produce this chord in JI. And be free to rewrite that section in terms of jubilismic temperaments.

::: There's a difference between an edo and its patent val; the val describes the corresponding rank-1 temperament. See [[EDO vs ET]]. Sometimes it's better to use the second-best approximation for a prime harmonic; for example, it's much better to use the 34d val than the patent val when using prime [[7/1|7]] in 34edo. In the patent val all of [[7/6]], [[7/5]], [[9/7]], [[14/11]], [[14/13]], [[15/14]], and their [[octave complement]]s are inconsistent, while in the 34d val only [[7/4]] and [[8/7]] are inconsistent. The ratios between harmonics are just as important as the harmonics themselves, and even more so when one realizes that there's much more of them. Also, the 34d val is much more useful than the 32edo or 54edo patent val.--[[User:Overthink|Overthink]] ([[User talk:Overthink|talk]]) 09:14, 25 December 2025 (UTC)

Semicomma family

Lériendil: /* Newspeak */

{{Technical data page}}
The [[5-limit]] parent [[comma]] for the '''semicomma family''' of [[regular temperament|temperaments]] is the [[semicomma]] ({{monzo|legend=1| -21 3 7 }}, [[ratio]]: 2109375/2097152). This is the amount by which three pure 3/1 twelfths exceed seven pure 8/5 minor sixths.

== Orson ==
'''Orson''', first discovered by [[Erv Wilson]]{{citation needed}}, is the [[5-limit]] temperament [[tempering out]] the semicomma. It has a [[generator]] of [[~]][[75/64]], seven of which give the [[3/1|perfect twelfth]]; its [[ploidacot]] is alpha-heptacot. The generator is sharper than [[7/6]] by [[225/224]] when untempered, and less sharp than that in any good orson tempering, for example [[53edo]] or [[84edo]]. These give tunings to the generator which are sharp of 7/6 by less than five [[cent]]s, making it hard to treat orson as anything other than an (at least) 7-limit system, leading to orwell.

=== Overview to extensions ===
The second comma of the [[Normal lists #Normal interval list|normal comma list]] defines which 7-limit family member we are looking at. Adding 65625/65536 (or 225/224) leads to orwell, but we could also add
* 1029/1024, leading to the {{nowrap| 31 & 159 }} temperament (triwell), or
* 2401/2400, giving the {{nowrap| 31 & 243 }} temperament (quadrawell), or
* 4375/4374, giving the {{nowrap| 53 & 243 }} temperament (sabric).

== Orwell ==
{{Main| Orwell }}

So called because 19\84 (as a fraction of the octave) is a possible generator of this temperament, orwell divides the interval of a twelfth (a tempered 3/1 frequency ratio) into 7 equal steps. It is compatible with [[22edo|22]], [[31edo|31]], [[53edo|53]] and [[84edo|84]] equal, and may be described as the {{nowrap| 22 & 31 }} temperament. It is a good system in the [[7-limit]] and naturally extends into the [[11-limit]]. [[84edo]], with the 19\84 generator, provides a good tuning for the 5-, 7- and 11-limit, but it does use its second-closest approximation to 11. However, the 19\84 generator is remarkably close to the 11-limit [[POTE tuning]], as the generator is only 0.0024 cents sharper, and it is a good approximation to the 7-limit POTE generator also; hence 84 may be considered the most recommendable tuning in the 7-limit. [[53edo]] might be preferred in the 5-limit because of its nearly pure fifth and in the 11-limit because of its slightly better 11, though most of its 11-limit harmony is actually worse. Aside from the semicomma and 65625/65536, 7-limit orwell tempers out [[2430/2401]] (the nuwell comma), [[1728/1715]] (the orwellisma), [[225/224]] (the marvel comma or septimal kleisma), and [[6144/6125]] (the porwell comma).

The 11-limit version of orwell tempers out [[99/98]], which means that two of its sharpened 7/6 generators give a flattened 11/8, as well as 121/120, 176/175, 385/384 and 540/539. Despite lowered tuning accuracy, orwell comes into its own in the 11-limit, giving acceptable accuracy and relatively low complexity. Tempering out the orwellisma, 1728/1715, means that orwell interprets three stacked 7/6 generators as an 8/5, and the tempered 1–7/6–11/8–8/5 chord is natural to orwell.

Orwell has [[mos scale]]s of size 9, 13, 22 and 31. The 9-note mos is small enough to be retained in the mind as a genuine scale, is pleasing melodically, and has [[Retuning 12edo to Orwell9|considerable harmonic resources]] despite its absence of 5-limit triads. The 13-note mos has those, and of course the 22- and 31-note mos are very well supplied with everything.

==== Doublethink ====
Doublethink is a weak extension of orwell to the 13-limit. It splits the generator of ~7/6 into two [[13/12]]~[[14/13]]'s by tempering out their difference, [[169/168]]. Its ploidacot is alpha-14-cot.

=== Newspeak ===
In newspeak, the simplicity of obtaining ~[[11/8]] by stacking the generator ~[[7/6]] twice (as in basic 11-limit orwell) is sacrificed to gain accuracy for larger equal temperaments (such as [[84edo]] and [[115edo]]), at the cost of much higher complexity: it is reached only after stacking the generator 33 times and octave-reducing. Newspeak intersects with undecimal orwell at [[31edo]].

Hemimean clan

2026-03-01T04:51:20Z

Lériendil: /* Rectified hebrew */

{{Technical data page}}
The '''hemimean clan''' [[Tempering out|tempers out]] the hemimean comma, [[3136/3125]], with [[monzo]] {{monzo| 6 0 -5 2 }}, such that [[7/4]] is split into five steps, of which two make [[5/4]] and three make [[7/5]]; this defines the [[2.5.7 subgroup]] temperament [[didacus]], generated by a tempered hemithird of [[28/25]].

The second comma of the comma list determines which 7-limit family member we are looking at. These [[extension]]s, in general, split the [[syntonic comma]] into two, each for [[126/125]]~[[225/224]], as 3136/3125 = (126/125)/(225/224). Hemiwürschmidt adds [[2401/2400]]; hemithirds adds [[1029/1024]]; spell adds [[49/48]]. These all use the same nominal generator as didacus.

Septimal passion adds [[64/63]], splitting the hemithird into a further two. Septimal meantone adds [[81/80]] as well as [[126/125]] and [[225/224]], splitting an octave plus the hemithird into two perfect fifths. Sycamore adds [[686/675]], splitting the hemithird into three. Semisept adds [[1728/1715]], splitting an octave plus the hemithird into three. Mohavila adds [[135/128]], whereas cohemimabila adds [[65536/64827]], both splitting two octaves plus the hemithird into three. Emka adds [[84035/82944]], splitting two octaves plus the hemithird into four. Bidia adds [[2048/2025]] with a 1/4-octave period. Misty adds [[5120/5103]] with a 1/3-octave period. Bischismic adds [[32805/32768]] with a semioctave period. Hexe adds [[50/49]] with a 1/6-octave period. Clyde adds [[245/243]] with a generator of ~9/7, five of which make the original. Parakleismic adds [[4375/4374]] with a generator of ~6/5. Arch adds [[5250987/5242880]] with a generator of ~64/63. For these seven generators make the original. Sengagen adds [[420175/419904]] with a generator of ~686/675, splitting the hemithird into eight. Subpental adds [[19683/19600]] with a generator of ~56/45, nine of which make the original.

Didacus has canonical subgroup extensions to primes 11 and 13, at [[#Undecimal didacus|undecimal didacus]]. Other subgroup extensions include rectified hebrew and isra.

'''Hemiwürschmidt''' (sometimes spelled '''hemiwuerschmidt''') is not only one of the more accurate extensions of didacus, but also the most important extension of 5-limit [[würschmidt]], even with the rather large complexity for the fifth. It tempers out [[2401/2400]], [[3136/3125]], and [[6144/6125]]. [[68edo]], [[99edo]] and [[130edo]] can all be used as tunings, but 130 is not only the most accurate, it shows how hemiwürschmidt extends to a higher limit temperament, mapping 11 to 40 generators and 13 to -39.

=== Quadrawürschmidt ===
This has been documented in Graham Breed's temperament finder as ''semihemiwürschmidt'', but ''quadrawürschmidt'' arguably makes more sense.

The generator of quadrawürschmidt is essentially a [[septimal meantone]] fifth. However, it is not used to represent [[3/2]], as 3/2 is found at the hemiwürschmidt position, 16 wholetones up. The small comma between the generator and 3/2 is taken to represent [[441/440]].

== Semisept ==
: ''For the 5-limit version of this temperament, see [[High badness temperaments #Semisept]].''

The minimal generator of semisept is half a tempered septimal major sixth (12/7), hence the name. Three such generator steps minus an octave give the hemithird, and six give the classical major third. It can be described as the 31 & 80 temperament, and as one may expect, [[111edo]] makes for a great tuning.

: ''For the 5-limit version, see [[Syntonic–chromatic equivalence continuum #Undetrita (5-limit)]].''

The undetrita temperament (111 & 118) tempers out the hemimean comma (3136/3125) and [[scheme comma]] (14348907/14336000) in the 7-limit; 3025/3024, 3388/3375, and 8019/8000 in the 11-limit. This temperament is related to [[11edt]], and the name ''undetrita'' is a play on the words ''undecimus'' (Latin for "eleventh") and ''[[tritave]]'' (3rd harmonic). It is also related to the [[Subgroup temperaments #No-sevens subgroup|twentcufo temperament]], which is no-sevens version of 111 & 118.

== Undecimal didacus ==
In the no-3's [[11-limit]], there is a natural extension with prime 11 by equating [[25/16]] (which is already tuned sharp anyways) with [[11/7]] by tempering out [[176/175]], which is the same route that [[undecimal meantone]] uses, as this is essentially a no-3's restriction of undecimal meantone in the 11-limit, except that undecimal meantone finds ~[[28/25]] at 2 generators (as a flat ~[[9/8]]) while here it is the generator. This is equivalent to finding [[11/4]] as ([[7/5]])3. In the no-3's 19-limit extension "mediantone", this whole tone generator serves as the two simplest [[mediant]]s of [[9/8]] and [[10/9]], namely [[19/17]] and [[28/25]], while in undecimal didacus and its extension to the no-3's 13-limit only the latter interpretation is relevant.

=== Tridecimal didacus ===
Tridecimal didacus (formerly ''roulette''; that name has now been reassigned to the no-threes 19-limit extension 37 & 68) is equivalent to [[hemiwur]] or [[grosstone]] with no mapping for prime 3. The mapping of prime 13 is somewhat strange, because it is the only mapping that requires a negative amount of generators (and a large amount of them), but it can be rationalized in a variety of ways, such as that because [[~]][[8/7]] is already tuned almost 3{{cent}} flat, it makes sense to equate two of it with [[~]][[13/10]] (tempering out the 8{{cent}} [[huntma]]). This mapping of 13 increases the [[badness]] of the temperament, but as it does not noticeably affect the optimal generators, it is usually a safe extension to didacus if prime 3 is not included.

==== Mediantone ====
Mediantone is named after its whole tone generator serving as the [[mediant]] of [[9/8]] and [[10/9]], namely [[19/17]], in addition to [[28/25]], as well as by the observation that this temperament seems to have been repeatedly rediscovered in parts in a variety of contexts, so that it seems to exist as a "median" of all of these temperaments' logics. It is also an intentional play on "[[meantone]]", as the context one is most likely to first discover this logic is when the tone also represents [[~]][[10/9]][[~]][[9/8]].

In the full no-3's [[19-limit]], this temperament is a structure common to quite a few temperaments. It is a rank-2 version of [[orion]] with a mapping for primes 11 and 13. It is a no-3's version of 19-limit [[grosstone]] which can be seen as an extension of [[undecimal meantone]] according to the "mediant-tone" logic of this temperament, and which as aforementioned effectively doubles the complexity of the temperament as a result of finding the generator of [[~]][[19/17]][[~]][[28/25]] as ([[~]][[3/2]])2/[[2/1|2]]. It does not work so well as an extension for [[hemiwur]] to the full 19-limit, but if you want to try anyway (at the cost of primes 17 and 19), a notable patent-val tuning is [[37edo]], which finds prime 3 through the [[würschmidt]] mapping so that [[6/1]] is found at 16 generators.

Roulette is an alternative no-threes 19-limit extension of tridecimal didacus to mediantone (the two mappings converging at [[37edo]]), equating (8/7)2 to [[17/13]] in addition to 13/10, tempering out [[170/169]] and [[833/832]]; in doing so, it also tempers out the micro-comma [[2000033/2000000]] so that ([[50/49]])3 is equated to [[17/16]]. The generator is then equated to 19/17 in the same way as in mediantone.

Hemimean clan

Lériendil: sycamore

{{Technical data page}}
The '''hemimean clan''' [[Tempering out|tempers out]] the hemimean comma, [[3136/3125]], with [[monzo]] {{monzo| 6 0 -5 2 }}, such that [[7/4]] is split into five steps, of which two make [[5/4]] and three make [[7/5]]; this defines the [[2.5.7 subgroup]] temperament [[didacus]], generated by a tempered hemithird of [[28/25]].

The second comma of the comma list determines which 7-limit family member we are looking at. These [[extension]]s, in general, split the [[syntonic comma]] into two, each for [[126/125]]~[[225/224]], as 3136/3125 = (126/125)/(225/224). Hemiwürschmidt adds [[2401/2400]]; hemithirds adds [[1029/1024]]; spell adds [[49/48]]. These all use the same nominal generator as didacus.

Septimal passion adds [[64/63]], splitting the hemithird into a further two. Septimal meantone adds [[81/80]] as well as [[126/125]] and [[225/224]], splitting an octave plus the hemithird into two perfect fifths. Sycamore adds [[686/675]], splitting the hemithird into three. Semisept adds [[1728/1715]], splitting an octave plus the hemithird into three. Mohavila adds [[135/128]], whereas cohemimabila adds [[65536/64827]], both splitting two octaves plus the hemithird into three. Emka adds [[84035/82944]], splitting two octaves plus the hemithird into four. Bidia adds [[2048/2025]] with a 1/4-octave period. Misty adds [[5120/5103]] with a 1/3-octave period. Bischismic adds [[32805/32768]] with a semioctave period. Hexe adds [[50/49]] with a 1/6-octave period. Clyde adds [[245/243]] with a generator of ~9/7, five of which make the original. Parakleismic adds [[4375/4374]] with a generator of ~6/5. Arch adds [[5250987/5242880]] with a generator of ~64/63. For these seven generators make the original. Sengagen adds [[420175/419904]] with a generator of ~686/675, splitting the hemithird into eight. Subpental adds [[19683/19600]] with a generator of ~56/45, nine of which make the original.

Didacus has canonical subgroup extensions to primes 11 and 13, at [[#Undecimal didacus|undecimal didacus]]. Other subgroup extensions include rectified hebrew and isra.

'''Hemiwürschmidt''' (sometimes spelled '''hemiwuerschmidt''') is not only one of the more accurate extensions of didacus, but also the most important extension of 5-limit [[würschmidt]], even with the rather large complexity for the fifth. It tempers out [[2401/2400]], [[3136/3125]], and [[6144/6125]]. [[68edo]], [[99edo]] and [[130edo]] can all be used as tunings, but 130 is not only the most accurate, it shows how hemiwürschmidt extends to a higher limit temperament, mapping 11 to 40 generators and 13 to -39.

=== Quadrawürschmidt ===
This has been documented in Graham Breed's temperament finder as ''semihemiwürschmidt'', but ''quadrawürschmidt'' arguably makes more sense.

The generator of quadrawürschmidt is essentially a [[septimal meantone]] fifth. However, it is not used to represent [[3/2]], as 3/2 is found at the hemiwürschmidt position, 16 wholetones up. The small comma between the generator and 3/2 is taken to represent [[441/440]].

== Semisept ==
: ''For the 5-limit version of this temperament, see [[High badness temperaments #Semisept]].''

The minimal generator of semisept is half a tempered septimal major sixth (12/7), hence the name. Three such generator steps minus an octave give the hemithird, and six give the classical major third. It can be described as the 31 & 80 temperament, and as one may expect, [[111edo]] makes for a great tuning.

== Undecimal didacus ==
In the no-3's [[11-limit]], there is a natural extension with prime 11 by equating [[25/16]] (which is already tuned sharp anyways) with [[11/7]] by tempering out [[176/175]], which is the same route that [[undecimal meantone]] uses, as this is essentially a no-3's restriction of undecimal meantone in the 11-limit, except that undecimal meantone finds ~[[28/25]] at 2 generators (as a flat ~[[9/8]]) while here it is the generator. This is equivalent to finding [[11/4]] as ([[7/5]])3. In the no-3's 19-limit extension "mediantone", this whole tone generator serves as the two simplest [[mediant]]s of [[9/8]] and [[10/9]], namely [[19/17]] and [[28/25]], while in undecimal didacus and its extension to the no-3's 13-limit only the latter interpretation is relevant.

=== Tridecimal didacus ===
Tridecimal didacus (formerly ''roulette''; that name has now been reassigned to the no-threes 19-limit extension 37 & 68) is equivalent to [[hemiwur]] or [[grosstone]] with no mapping for prime 3. The mapping of prime 13 is somewhat strange, because it is the only mapping that requires a negative amount of generators (and a large amount of them), but it can be rationalized in a variety of ways, such as that because [[~]][[8/7]] is already tuned almost 3{{cent}} flat, it makes sense to equate two of it with [[~]][[13/10]] (tempering out the 8{{cent}} [[huntma]]). This mapping of 13 increases the [[badness]] of the temperament, but as it does not noticeably affect the optimal generators, it is usually a safe extension to didacus if prime 3 is not included.

==== Mediantone ====
Mediantone is named after its whole tone generator serving as the [[mediant]] of [[9/8]] and [[10/9]], namely [[19/17]], in addition to [[28/25]], as well as by the observation that this temperament seems to have been repeatedly rediscovered in parts in a variety of contexts, so that it seems to exist as a "median" of all of these temperaments' logics. It is also an intentional play on "[[meantone]]", as the context one is most likely to first discover this logic is when the tone also represents [[~]][[10/9]][[~]][[9/8]].

In the full no-3's [[19-limit]], this temperament is a structure common to quite a few temperaments. It is a rank-2 version of [[orion]] with a mapping for primes 11 and 13. It is a no-3's version of 19-limit [[grosstone]] which can be seen as an extension of [[undecimal meantone]] according to the "mediant-tone" logic of this temperament, and which as aforementioned effectively doubles the complexity of the temperament as a result of finding the generator of [[~]][[19/17]][[~]][[28/25]] as ([[~]][[3/2]])2/[[2/1|2]]. It does not work so well as an extension for [[hemiwur]] to the full 19-limit, but if you want to try anyway (at the cost of primes 17 and 19), a notable patent-val tuning is [[37edo]], which finds prime 3 through the [[würschmidt]] mapping so that [[6/1]] is found at 16 generators.

==== Roulette ====
{{See also | Chromatic pairs #Roulette }}

Roulette is an alternative no-threes 19-limit extension of tridecimal didacus to mediantone (the two mappings converging at [[37edo]]), equating (8/7)2 to [[17/13]] in addition to 13/10, tempering out [[170/169]] and [[833/832]]; in doing so, it also tempers out the micro-comma [[2000033/2000000]] so that ([[50/49]])3 is equated to [[17/16]]. The generator is then equated to 19/17 in the same way as in mediantone.
