== Sensi ==
=== Overview to extensions ===
{{main| Sensi }}
The full 7-limit extensions' relation to BPS is clearer if the mapping is normalized in terms of 3.5.7.2. In fact, the strong extensions are sensi, cohemiripple, hedgehog, and fourfives.
{{see also| Sensipent family #Sensi }}


Sensi tempers out [[126/125]], [[686/675]] and [[4375/4374]] in addition to [[245/243]], and can be described as the 19&27 temperament. It has as a generator half the size of a slightly wide major sixth, which gives an interval sharp of 9/7 and flat of 13/10, both of which can be used to identify it, as 2.3.5.7.13 sensi (sensation) tempers out 91/90. 22/17, in the middle, is even closer to the generator. [[46edo]] is an excellent sensi tuning, and MOS of size 11, 19 and 27 are available. The name "sensi" is a play on the words "semi-" and "sixth."
These temperaments are distributed into different family pages.
* [[Sensi]] (+126/125) → [[Sensipent family #Sensi|Sensipent family]]
* ''[[Hedgehog]]'' (+50/49) → [[Porcupine family #Hedgehog|Porcupine family]]
* ''[[Cohemiripple]]'' (+1323/1250) → [[Ripple family #Cohemiripple|Ripple family]]
* ''[[Fourfives]]'' (+235298/234375) → [[Fifive family #Fourfives|Fifive family]]


=== Septimal sensi ===
The others are weak extensions. Father tempers out [[16/15]], splitting the generator in two. Godzilla tempers out [[49/48]] with a hemitwelfth period. Sidi tempers out [[25/24]], splitting the generator in two with a hemitwelfth period. Clyde tempers out [[3136/3125]] with a 1/6-twelfth period. Superpyth tempers out [[64/63]], splitting the generator in six. Magic tempers out [[225/224]] with a 1/5-twelfth period. Octacot tempers out [[2401/2400]], splitting the generator in five. Hemiaug tempers out [[128/125]]. Pentacloud tempers out [[16807/16384]]. These split the generator in seven. Bamity tempers out [[64827/64000]], splitting the generator in nine. Rodan tempers out [[1029/1024]], splitting the generator in ten. Shrutar tempers out [[2048/2025]], splitting the generator in eleven. Salsa tempers out [[32805/32768]], splitting the generator in fifteen. Finally, escaped tempers out [[65625/65536]], splitting the generator in sixteen.

Bohpier tempers out 3125/3087 and may be described as the {{nowrap| 41 & 49 }} temperament. It is named after its interesting [[relationship between Bohlen–Pierce and octave-ful temperaments|relationship with the non-octave Bohlen–Pierce equal temperament]].


POTE generator: ~9/7 = 443.294
[[41edo]] itself makes for an excellent tuning, though [[90edo]] and [[131edo]] are interesting alternatives. Another notable tuning is given by [[TE]], [[CTE]] and [[POTE]], all coinciding at 146.4741{{c}} with pure octaves since prime 2 is not involved in the comma to begin with, though its difference from [[WE]] and/or [[CWE]] (shown below) is largely unnoticeable.

This temperament is also called as "sensa" because it tempers out 245/243, 352/351, and 385/384 as a sensamagic temperament. ''Not to be confused with 19e&27 temperament (sensi extension).''
Pycnic is related to [[triton]], but its mapping differs for the [[7/1|7th harmonic]]. It is also related to [[liese]], from which its mapping differs for the [[5/1|5th harmonic]].


Subgroup: 2.3.5.7
The fifth of pycnic in size is a meantone fifth, but four of them are not used to reach 5. This has the effect of making the Pythagorean major third, nominally 81/64, very close to 5/4 in tuning, being two cents sharp of it in the CWE tuning for instance. Pycnic has [[mos]] of size 9, 11, 13, 15, 17… which contain these alternative thirds, leading to two kinds of major triads, an official one and a nominally Pythagorean one which is actually in better tune.

Badness: 0.031366
Magus temperament tempers out [[50331648/48828125]] in the 5-limit. This temperament can be described as {{nowrap| 46 & 49 }} temperament, which tempers out the sensamagic and [[28672/28125]]. The alternative extension [[starling temperaments #Amigo|amigo]] ({{nowrap| 43 & 46 }}) tempers out the same 5-limit comma as the magus, but with the [[126/125|starling comma]] (126/125) rather than the sensamagic tempered out.


== Salsa ==
Magus has a generator of a sharp ~5/4, and ~[[25/16]] is twice as sharp so that it makes sense to equate with [[11/7]] by tempering out [[176/175]]), so that three reaches [[128/125]] short of the octave, where 128/125 is tuned narrow; this is significant because magus reaches [[3/2]] as ([[25/16]])/([[128/125]])<sup>3</sup>, that is, {{nowrap| 2 + 3 × 3 {{=}} 11 }} generators. Therefore, it implies that [[25/24]] is split into three [[128/125]]'s. Therefore, in the 5-limit, magus can be thought of as a higher-complexity and sharper analogue of [[würschmidt]] (which reaches [[3/2]] as (25/16)/(128/125)<sup>2</sup> implying 25/24 is split into two 128/125's thus having a guaranteed neutral third), which itself is a higher-complexity and sharper analogue of [[magic]] (which equates 25/24 with 128/125 by flattening 5). For more details on these connections see [[Würschmidt comma]].

This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

The sensamagic clan of temperaments tempers out the sensamagic comma, 245/243, a triprime comma with no factors of 2, ⟨0 -5 1 2] to be exact.

Tempering out 245/243 alone in the full 7-limit leads to a rank-3 temperament, sensamagic, for which 283edo is the optimal patent val.

BPS

Main article: BPS

BPS, for Bohlen–Pierce–Stearns, is the 3.5.7-subgroup temperament tempering out 245/243. This subgroup temperament was formerly called the lambda temperament, which was named after the lambda scale.

Subgroup: 3.5.7

Comma list: 245/243

Subgroup-val mapping: [⟨1 1 2], ⟨0 2 -1]]

mapping generators: ~3, ~9/7

Optimal tunings:

  • WE: ~3 = 1903.7398 ¢, ~9/7 = 440.9014 ¢
error map: ⟨+1.785 -0.771 -2.248]
  • CWE: ~3 = 1901.9550 ¢, ~9/7 = 440.6646 ¢

Badness (Sintel): 0.0659

Overview to extensions

The full 7-limit extensions' relation to BPS is clearer if the mapping is normalized in terms of 3.5.7.2. In fact, the strong extensions are sensi, cohemiripple, hedgehog, and fourfives.

These temperaments are distributed into different family pages.

The others are weak extensions. Father tempers out 16/15, splitting the generator in two. Godzilla tempers out 49/48 with a hemitwelfth period. Sidi tempers out 25/24, splitting the generator in two with a hemitwelfth period. Clyde tempers out 3136/3125 with a 1/6-twelfth period. Superpyth tempers out 64/63, splitting the generator in six. Magic tempers out 225/224 with a 1/5-twelfth period. Octacot tempers out 2401/2400, splitting the generator in five. Hemiaug tempers out 128/125. Pentacloud tempers out 16807/16384. These split the generator in seven. Bamity tempers out 64827/64000, splitting the generator in nine. Rodan tempers out 1029/1024, splitting the generator in ten. Shrutar tempers out 2048/2025, splitting the generator in eleven. Salsa tempers out 32805/32768, splitting the generator in fifteen. Finally, escaped tempers out 65625/65536, splitting the generator in sixteen.

Discussed elsewhere are

For no-twos extensions, see No-twos subgroup temperaments #BPS.

Considered below are bohpier, pycnic, superenneadecal, superthird, magus and leapweek.

Bohpier

Main article: Bohpier
For the 5-limit version, see Miscellaneous 5-limit temperaments #Bohpier.

Bohpier tempers out 3125/3087 and may be described as the 41 & 49 temperament. It is named after its interesting relationship with the non-octave Bohlen–Pierce equal temperament.

41edo itself makes for an excellent tuning, though 90edo and 131edo are interesting alternatives. Another notable tuning is given by TE, CTE and POTE, all coinciding at 146.4741 ¢ with pure octaves since prime 2 is not involved in the comma to begin with, though its difference from WE and/or CWE (shown below) is largely unnoticeable.

Pycnic

For the 5-limit version, see Syntonic–kleismic equivalence continuum #Stump.

Pycnic is related to triton, but its mapping differs for the 7th harmonic. It is also related to liese, from which its mapping differs for the 5th harmonic.

The fifth of pycnic in size is a meantone fifth, but four of them are not used to reach 5. This has the effect of making the Pythagorean major third, nominally 81/64, very close to 5/4 in tuning, being two cents sharp of it in the CWE tuning for instance. Pycnic has mos of size 9, 11, 13, 15, 17… which contain these alternative thirds, leading to two kinds of major triads, an official one and a nominally Pythagorean one which is actually in better tune.

Subgroup: 2.3.5.7

Comma list: 245/243, 525/512

Mapping: [⟨1 0 6 -3], ⟨0 3 -7 11]]

Badness (Sintel): 1.87

Xenia

For the 5-limit version, see Syntonic–kleismic equivalence continuum #Xenial.

Xenia is related to xenial, but its mapping differs for the 7th harmonic. It may be described as 19 & 51c or 19 & 70d, which tempers out the sensamagic and keega, 1029/1000.

Subgroup: 2.3.5.7

Comma list: 245/243, 1029/1000

Mapping: [⟨1 -6 -12 -9], ⟨0 9 17 14]]

  • WE: ~2 = 1201.0862 ¢, ~9/5 = 1012.0503 ¢

error map: ⟨0.000 -0.976 +4.424 -11.748]

Optimal ET sequence: 19, 70d, 89d

Badness (Sintel): 2.25

Magus

For the 5-limit version, see Miscellaneous 5-limit temperaments #Magus.

Magus temperament tempers out 50331648/48828125 in the 5-limit. This temperament can be described as 46 & 49 temperament, which tempers out the sensamagic and 28672/28125. The alternative extension amigo (43 & 46) tempers out the same 5-limit comma as the magus, but with the starling comma (126/125) rather than the sensamagic tempered out.

Magus has a generator of a sharp ~5/4, and ~25/16 is twice as sharp so that it makes sense to equate with 11/7 by tempering out 176/175), so that three reaches 128/125 short of the octave, where 128/125 is tuned narrow; this is significant because magus reaches 3/2 as (25/16)/(128/125)3, that is, 2 + 3 × 3 = 11 generators. Therefore, it implies that 25/24 is split into three 128/125's. Therefore, in the 5-limit, magus can be thought of as a higher-complexity and sharper analogue of würschmidt (which reaches 3/2 as (25/16)/(128/125)2 implying 25/24 is split into two 128/125's thus having a guaranteed neutral third), which itself is a higher-complexity and sharper analogue of magic (which equates 25/24 with 128/125 by flattening 5). For more details on these connections see Würschmidt comma.
