Porwell temperaments: Difference between revisions

Latest revision as of 10:17, 28 May 2026

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.

This is a collection of temperaments that temper out the porwell comma (monzo: [11 1 -3 -2⟩, ratio: 6144/6125).

Temperaments discussed elsewhere are:

Armodue (+36/35) → Mavila family
Mohajira (+81/80) → Meantone family
Hemischis (+19683/19600) → Schismatic family
Porcupine (+64/63) → Porcupine family
Alphatrident (+14348907/14336000) → Alphatricot family
Shrutar (+245/243) → Diaschismic family
Amity (+4375/4374 or 5120/5103) → Amity family
Orwell (+225/224) → Semicomma family
Twilight (+[19 -22 2 4⟩) → Undim family
Valentine (+126/125) → Starling temperaments
Freivald (+6272/6075) → Passion family
Decimaleap (+[15 -18 1 4⟩) → Quintaleap family
Hemikleismic (+4000/3969) → Kleismic family
Bison (+78732/78125) → Sensipent family
Quinkee (+1029/1000) → Cloudy clan
Hemiwürschmidt (+2401/2400 or 3136/3125) → Hemimean clan
Septisuperfourth (+118098/117649) → Escapade family
Hemimabila (+117649/116640) → Mabila family
Countermiracle (+823543/819200) → Quince clan
Hemimaquila (+[-5 10 5 -8⟩) → Maquila family

Considered below are hendecatonic, nessafof, grendel, twothirdtonic, aufo, absurdity, polypyth, whoops, dodifo, and icositritonic, in the order of increasing badness.

Hendecatonic

For the 5-limit version, see 11th-octave temperaments #Hendecapent.

The hendecatonic temperament has a period of 1/11 octave, which represents 16/15 and four times of which represent 9/7. It tempers out 10976/10935, the hemimage comma, and may be described as the 22 & 99 temperament, with 99edo giving an almost perfect tuning.

Nessafof

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

Cryptically named by Petr Pařízek in 2011^[1], nessafof adds the landscape comma and has a third-octave period. The name actually refers to the fact that it has a neutral-second generator, and that a semi-augmented fourth, stacked five times, makes 5/1^[2].

Grendel

For the 5-limit version, see Syntonic–31 equivalence continuum #Counterwürschmidt.

Grendel tempers out 16875/16807, the mirkwai comma, and may be described as the 31 & 152 temperament. 152edo, 183edo and especially 335edo serve as good tunings.

Twothirdtonic

Twothirdtonic tempers out 686/675, the senga, in addition to the porwell comma, and may be described as the 37 & 46 temperament, generated by one third of a classical major third that represents 15/14, 14/13, and 13/12 in the 13-limit interpretation. Note that in the data below, the generator is taken to be its octave complement, thirteen of which octave reduced make the perfect fifth; it follows that the ploidacot for this temperament is 11-sheared 13-cot. 46edo may be recommended as a tuning.

Semaja

See also: Llywelynsmic clan

Cryptically named by Petr Pařízek in 2011, semaja adds the gariboh comma to the comma list, and may be described as the 37 & 53 temperament. Its ploidacot is gamma-19-cot (or alpha-heptaseph due to a much simpler 2.5.7-subgroup restriction). The name actually refers to the fact that two of its ~8/7 generator steps reach a ~13/10^[2].

Aufo

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

Also named by Petr Pařízek in 2011, aufo refers to the augmented fourth, which is a generator of this temperament^[2]. The functional generator however is the 64/45 diminished fifth, and like its untriton variant, nine generator steps give the interval class of 3. The ploidacot for this temperament is delta-enneacot.

Polypyth

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

Polypyth tempers out the same 5-limit comma as leapday, with which it shares the similarly sharp perfect-fifth generator, but the porwell comma (6144/6125) rather than the hemifamity comma (5120/5103) is tempered out here. It may be described as the 46 & 121 temperament, and 121edo and 167edo make for good tunings.

Whoops

For the 5-limit version, see Very high accuracy temperaments #Whoosh.

Dodifo

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

Also named by Petr Pařízek in 2011, dodifo refers to the (tetraptolemaic) double-diminished fourth, which is a generator of this temperament^[2]. The extension here is a less accurate 7-limit interpretation.

Icositritonic

See also: 23rd-octave temperaments

Icositritonic has a period of 1/23 octave, so six period represents 6/5 and nine period represents 21/16. It may be described as 46 & 161. It was named by Xenllium in 2019 for its number of periods per octave.

+Icositritonic has a period of 1/23 octave, so six period represents [[6/5]] and nine period represents [[21/16]]. It may be described as {{nowrap| 46 & 161 }}. It was named by [[Xenllium]] in 2019 for its number of periods per octave.
