The [[5-limit]] parent comma for the '''schismatic''' (or '''schismic''') '''family''' is the [[schisma]] of 32805/32768, which is the amount by which the [[Pythagorean comma]] exceeds the [[syntonic comma]] (81/80), or alternatively put, the difference between a [[5/4|just major third]] and a [[8192/6561|Pythagorean diminished fourth]]. | |||

{{Main| Schismic }} | |||
The 5-limit version of the temperament is a [[microtemperament]], called ''schismic'', ''schismatic'', or ''helmholtz''. The generator is a fifth, flattened by a fraction of a schisma, and 5/4 is represented by a diminished fourth. This defies the tradition of {{w|tertian harmony}}, as the [[just major triad]] on C is C–F♭–G, for example. One may want to adopt an additional module of accidentals such as arrows to represent the comma step, allowing them to write the chord above as C–vE–G. | |||
The 5-limit version of the temperament is a [[microtemperament]], | |||
As a 5-limit system, schismic is far more accurate than [[meantone]] but still with manageable [[complexity]]. [[53edo]] is a possible tuning for schismic, but you need [[118edo]] if you want to get the full effect. In exact analogy with [[1/4-comma meantone]] there is also 1/8 schismic, with pure major thirds and fifths flattened by 1/8 schisma. Since 1/8 of a schisma is 0.244{{cent}}, this falls into the range of microtempering. You could also try 1/9 schisma, with pure minor thirds and a minutely better fifth, or 2/17 schisma, with both thirds flat by 1/17 of a schisma, although the differences would be very hard to distinguish unless using a large gamut. Simply leaving the fifths just would also make for a viable tuning, thus collapsing schismic to a simple relabeling of the 3-limit. | |||

== | == Schism == | ||
See [[Archytas clan #Schism]]. | |||
Schism is a relatively low-accuracy extension as it tempers out the septimal comma. The 7/4 is found at -2 fifths, represented by the minor seventh (C–B♭). 12edo is recommendable tuning, though 29edo (29d val), 41edo (41d val), and 53edo (53d val) can be used. | |||
== Bischismic == | |||
Bischismic tempers out 3136/3125, the [[hemimean comma]], as well as 321489/320000, the [[varunisma]], and may be described as the {{nowrap| 118 & 130 }} temperament. The octave is split in halves, so the [[ploidacot]] of this temperament is diploid monocot. In schismic, -10 fifths make the interval class of 10/9. Bischismic then finds [[7/4]] by a stack of two [[10/9]]'s plus a semi-octave period, and in the [[11-limit]], it simply finds [[11/8]] by a stack of three [[10/9]]'s. [[248edo]] and [[378edo]] make for excellent tunings in both cases. | |||

Kleischismic tempers out 1500625/1492992, the [[uniwiz comma]], and may be described as the {{nowrap| 94 & 118 }} temperament. The generator is a infrafifth, two of which plus a semi-octave period make the [[3/1|3rd]] [[harmonic]]; its [[ploidacot]] is thus diploid alpha-dicot. In schismic, 10 fifths make the interval class of [[9/5]]. Kleischismic then finds [[7/4]] by that minus a [[36/35]] quartertone, which is the aforementioned generator minus a semi-octave period. The generator stands in for [[16/11]] and the quartertone stands in for [[33/32]] in the [[11-limit]]. [[212edo]] and [[330edo]] in the 330e val may be recommended as tunings. | |||

== | == Term == | ||
Term tempers out the [[landscape comma]], mapping [[63/50]] to the 1/3-octave period. It can be described as {{nowrap| 12 & 171 }}, and is the unique temperament that tempers together the syntonic and Pythagorean commas and equates it with a stack of three [[marvel comma]]s. A [[septimal comma]] is then found as a stack of four marvel commas. In certain 7-limit adaptive-tuning practice, the marvel comma corresponds to a melodic unit called a [[kleisma #As an interval region|kleisma]], with three kleismas making a comma, so this temperament may be useful for modeling that. [[171edo]] makes for an excellent tuning. | |||

Named by [[Xenllium]] in 2021, quadrant tempers out 390625/388962, the [[dimcomp comma]], and maps [[25/21]] to the 1/4-octave period. It may be described as the {{nowrap| 12 & 212 }} temperament; its ploidacot is tetraploid monocot. Just as [[#Term|term]] equates the syntonic~Pythagorean comma with three [[marvel comma]]s, quadrant equates the syntonic~Pythagorean comma with four.

== Septiquarschis == | |||
Named by [[Xenllium]] in 2021, septiquarschis tempers out [[829440/823543]] (mynaslender comma) and [[67108864/66706983]] (septiness comma), and may be described as the {{nowrap| 89 & 94 }} temperament. It splits septimal minor seventh ([[7/4]]) into four generators. Note that in the data below, the generator is the [[octave complement]] so that seven of them minus five octaves make a [[3/2|perfect fifth]]; its [[ploidacot]] is thus epsilon-heptacot. | |||

Proposed by [[Eufalesio]] in 2026, tridecaschismic adds the [[325/324|marveltwin comma]] to the comma list, or equivalently, the [[tridecapyth comma]]. It benefits from a fifth that is just, or practically indistinguishable from just, like in 53edo. It is one of the lowest badness schismic extensions. It is also equivalent to the 2.3.5.13 [[restriction]] of 13-limit [[cassandra]]. | |||

=== Nestoria (2.3.5.19) === | |||

Nestoria is notable for having one of the lowest-badness subgroup extensions of schismic. Note that despite prime [[19/1|19]] being optimized by a flatter fifth, the fifth in optimal tunings of nestoria is generally not flatter than the fifth in optimal schismic due to its optimization considering intervals like [[19/10]] and [[19/15]]. However, the dyadic tuning sensitivity of [[19/16]] suggests using tunings like [[65edo]] and [[77edo]] to optimize in favour of prime 19 (especially the minor triad ~16:19:24 which is equated with the Pythagorean minor triad), as [[171edo]] is already arguably undertempered for it despite being the optimal patent val. | |||

- 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 5-limit parent comma for the schismatic (or schismic) family is the schisma of 32805/32768, which is the amount by which the Pythagorean comma exceeds the syntonic comma (81/80), or alternatively put, the difference between a just major third and a Pythagorean diminished fourth.
Schismic, schismatic, a.k.a. helmholtz
The 5-limit version of the temperament is a microtemperament, called schismic, schismatic, or helmholtz. The generator is a fifth, flattened by a fraction of a schisma, and 5/4 is represented by a diminished fourth. This defies the tradition of tertian harmony, as the just major triad on C is C–F♭–G, for example. One may want to adopt an additional module of accidentals such as arrows to represent the comma step, allowing them to write the chord above as C–vE–G.
As a 5-limit system, schismic is far more accurate than meantone but still with manageable complexity. 53edo is a possible tuning for schismic, but you need 118edo if you want to get the full effect. In exact analogy with 1/4-comma meantone there is also 1/8 schismic, with pure major thirds and fifths flattened by 1/8 schisma. Since 1/8 of a schisma is 0.244 ¢, this falls into the range of microtempering. You could also try 1/9 schisma, with pure minor thirds and a minutely better fifth, or 2/17 schisma, with both thirds flat by 1/17 of a schisma, although the differences would be very hard to distinguish unless using a large gamut. Simply leaving the fifths just would also make for a viable tuning, thus collapsing schismic to a simple relabeling of the 3-limit.

Overview to extensions
The second comma of the normal comma list defines which 7-limit family member we are looking at. Garibaldi adds [25 -14 0 -1⟩, grackle adds [-44 26 0 1⟩, pontiac adds [-59 39 0 -1⟩, and schism adds [6 -2 0 -1⟩. Those all have a fifth as generator.
Bischismic adds [-69 40 0 2⟩ and has a fifth generator with a half-octave period. Salsa adds [15 -13 0 2⟩ and has a hemififth generator. Hemischis adds [-34 25 0 -2⟩ and has a hemitwelfth generator. Guiron adds [-10 1 0 3⟩, with an ~8/7 generator, three of which give the fifth. Term adds [-94 54 0 3⟩ with a 1/3-octave period. Squirrel, tertiaschis, and countertertiaschis each has a generator that is 1/3 of the fourth. Quadrant adds [-119 68 0 4⟩ with a 1/4-octave period. Kleischismic adds [49 -38 0 4⟩ with a half-octave period and also a bisect generator. Sesquiquartififths adds [-35 15 0 4⟩ and slices the fifth in four.
Temperaments involving larger splits include tsaharuk, quanharuk, quintilipyth, quintaschis, altinex, pogo, sextilifourths, septant, octant, nonant, septiquarschis, and tridecafifths. Those split the schismic structure into five to thirteen parts.
Temperaments discussed elsewhere include:
- Guiron (+1029/1024) → Gamelismic clan
- Pogo (+118098/117649) → Stearnsmic clan
Considered below are garibaldi, pontiac, grackle, schism, bischismic, kleischismic, salsa, hemischis, term, altinex, squirrel, tertiaschis, countertertiaschis, quadrant, sesquiquartififths, tsaharuk, quanharuk, quintilipyth, quintaschis, sextilifourths, septant, octant, nonant, septiquarschis, and tridecafifths.
The schismatic family boasts a variety of remarkable extensions to subgroups in high prime limits. These are listed at the bottom of this page, in #Subgroup extensions.
Garibaldi
Garibaldi tempers out the garischisma, equating the septimal comma with both the syntonic comma and the Pythagorean comma. The 7/4 is found at -14 fifths, represented by the double-diminished octave (C–C𝄫), or down-minor seventh (C-vB♭) with the down-arrow representing the comma step. It necessitates a sharper fifth than pure. Its S-expression-based comma list is {S8/S9, S15}.

Schism
Schism is a relatively low-accuracy extension as it tempers out the septimal comma. The 7/4 is found at -2 fifths, represented by the minor seventh (C–B♭). 12edo is recommendable tuning, though 29edo (29d val), 41edo (41d val), and 53edo (53d val) can be used.
Bischismic
Bischismic tempers out 3136/3125, the hemimean comma, as well as 321489/320000, the varunisma, and may be described as the 118 & 130 temperament. The octave is split in halves, so the ploidacot of this temperament is diploid monocot. In schismic, -10 fifths make the interval class of 10/9. Bischismic then finds 7/4 by a stack of two 10/9's plus a semi-octave period, and in the 11-limit, it simply finds 11/8 by a stack of three 10/9's. 248edo and 378edo make for excellent tunings in both cases.

Kleischismic
Kleischismic tempers out 1500625/1492992, the uniwiz comma, and may be described as the 94 & 118 temperament. The generator is a infrafifth, two of which plus a semi-octave period make the 3rd harmonic; its ploidacot is thus diploid alpha-dicot. In schismic, 10 fifths make the interval class of 9/5. Kleischismic then finds 7/4 by that minus a 36/35 quartertone, which is the aforementioned generator minus a semi-octave period. The generator stands in for 16/11 and the quartertone stands in for 33/32 in the 11-limit. 212edo and 330edo in the 330e val may be recommended as tunings.

Hemischis
Hemischis tempers out 6144/6125, the porwell comma, as well as 19683/19600, the cataharry comma, and may be described as the 53 & 130 temperament. Its ploidacot is alpha-dicot.

Term
Term tempers out the landscape comma, mapping 63/50 to the 1/3-octave period. It can be described as 12 & 171, and is the unique temperament that tempers together the syntonic and Pythagorean commas and equates it with a stack of three marvel commas. A septimal comma is then found as a stack of four marvel commas. In certain 7-limit adaptive-tuning practice, the marvel comma corresponds to a melodic unit called a kleisma, with three kleismas making a comma, so this temperament may be useful for modeling that. 171edo makes for an excellent tuning.

Named by Xenllium in 2021, sextilifourths (also known as sextilischis, formerly sextilififths) slices the perfect fourth into six small semitones, which serves as both 21/20 and 22/21. It may be described as 130 & 159, and its ploidacot is omega-hexacot. 289edo gives a highly recommendable tuning.

Septiquarschis
Named by Xenllium in 2021, septiquarschis tempers out 829440/823543 (mynaslender comma) and 67108864/66706983 (septiness comma), and may be described as the 89 & 94 temperament. It splits septimal minor seventh (7/4) into four generators. Note that in the data below, the generator is the octave complement so that seven of them minus five octaves make a perfect fifth; its ploidacot is thus epsilon-heptacot.

Subgroup extensions
Tridecaschismic (2.3.5.13)
Proposed by Eufalesio in 2026, tridecaschismic adds the marveltwin comma to the comma list, or equivalently, the tridecapyth comma. It benefits from a fifth that is just, or practically indistinguishable from just, like in 53edo. It is one of the lowest badness schismic extensions. It is also equivalent to the 2.3.5.13 restriction of 13-limit cassandra.

Nestoria (2.3.5.19)
- See also: No-elevens subgroup temperaments #Garibaldia and #Pontia
Nestoria is notable for having one of the lowest-badness subgroup extensions of schismic. Note that despite prime 19 being optimized by a flatter fifth, the fifth in optimal tunings of nestoria is generally not flatter than the fifth in optimal schismic due to its optimization considering intervals like 19/10 and 19/15. However, the dyadic tuning sensitivity of 19/16 suggests using tunings like 65edo and 77edo to optimize in favour of prime 19 (especially the minor triad ~16:19:24 which is equated with the Pythagorean minor triad), as 171edo is already arguably undertempered for it despite being the optimal patent val.
