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 2.3.7-subgroup comma for the gamelismic clan is the gamelisma, 1029/1024, with monzo [-10 1 0 3⟩. For any member of the clan, for the rank-3 gamelismic temperament itself, and for the rank-2 2.3.7 temperament slendric (a.k.a. gamelic), this means three ~8/7 intervals give a fifth, 3/2. In fact, we find that 3/2 = (8/7)3⋅(1029/1024). From this it follows that gamelismic temperaments tend to flatten both the fifth and the harmonic seventh, or if they do not, the other of the pair must be flattened even more. 36edo is a good tuning for slendric, though if the full 7-limit is desired, 72edo, 77edo, or 118edo might be preferred.

Overview to extensions

Full 7-limit extensions

To the gamelisma itself we need to add the comma which appears next on the modified normal comma list for the full 7-limit. The second comma on the list for mothra is 81/80, for rodan 245/243, for guiron 32805/32768, for gorgo 36/35, and for gidorah 256/245. These all use ~8/7 as a generator, though in the case of gidorah that is the same as ~6/5.

Miracle adds 33075/32768 and uses the secor, half an ~8/7, as generator. Lemba adds 525/512 to the list, and has a half-octave period. Valentine adds 6144/6125 with a generator of ~21/20 and superkleismic adds 875/864 with a generator of ~6/5. Unidec adds 4375/4374, and has a generator of ~10/9 with a half-octave period. Hemithirds adds 65625/65536 with a generator half of a classical major third. Finally, tritikleismic adds 15625/15552 and has a generator of 6/5 with a 1/3-octave period.

The rest are considered below.

Subgroup extensions

No-five subgroup extensions of slendric include radon, a 2.3.7.11-subgroup extension that may be viewed as no-five rodan, considered below, euslendric, a 2.3.7.13-subgroup extension, baladic, a weak 2.3.7.13.17-subgroup extension, and gigapyth, a 2.3.7.85-subgroup extension, considered in #Other subgroup extensions. Dicussed elsewhere is trisect in the 2.3.7.11/5 subgroup.

Radon

Mothra

Main article: Mothra

Mothra tempers out 81/80 and finds the prime 5 at a stack of four fifths as does any temperament in the meantone family. It also tempers out 1728/1715, the orwellisma. It can be described as the 26 & 31. Using 31edo with a generator of 6/31 is an excellent tuning choice. However, a pure mos mothra scale is often described as directionless and has limited chord-building potential[1], so something other than a mos may be used as a scale to get the most out of mothra. There are examples of non-mos mothra scales in 31edo in the article on strictly proper 7-tone 31edo scales.

Note that mothra is also called cynder in the 7-limit, which can be a little confusing sometimes.

Its S-expression-based comma list is {S6/S7, S7/S8, (S6/S8 = S9)}, taking advantage of the fact that 81/80 is a semiparticular.

Undecimal mothra

Undecimal mothra is the extension of 7-limit cynder which tempers out 385/384 as is natural in slendric temperaments. It is the simplest extension, supported within a reasonable tuning range (between 26edo and 31edo), and is supported by the patent val of 5edo, which implies that it is better behaved as a cluster temperament. It is also notable for being supported by the just tuning of 8/7, and has a restriction to the 2.7.11 subgroup, namely amaranthine, that is a microtemperament.

Rodan

Main article: Rodan
For the 5-limit version, see Syntonic–diatonic equivalence continuum #Rodan (5-limit).

Rodan tempers out 245/243 and can be described as the 41 & 46 temperament. This temperament is more accurate than mothra and extends neatly to the 13-limit, though the perfect fifth is sharper than ideal for slendric. 87edo is excellent for this, with the 17\87 generator missing the 13-limit CWE tuning by less than a millicent.

Guiron

Guiron tempers out the schisma, and finds the prime 5 at the diminished fourth as does any temperament in the schismatic family. It can be described as the 36 & 41 temperament. It is more complex than rodan, but the optimal tuning is closer to optimal slendric.

Gorgo

For the 5-limit version, see Syntonic–diatonic equivalence continuum #Laconic.
See also: Llywelynsmic clan

Gorgo tempers the generator of ~8/7 together with ~10/9. It can be described as the 16 & 21 temperament.

If we discard the inaccurate mapping of prime 3, we get shoe, so that the large commas of gorgo are explained practically entirely by the inaccurate 3.

Miracle

Main article: Miracle
For the 5-limit version, see Syntonic–31 equivalence continuum #Ampersand.

Miracle is one of the most important entries of this temperament clan. It tempers out 225/224, splitting the ~8/7 generator of slendric into 15/14~16/15, and can be described as the 31 & 41 temperament. Its ploidacot is hexacot. It is then extremely natural to equate the neutral third, three generators up, to 11/9 and thereby extend miracle to the full 11-limit with essentially no further damage. 72edo makes for an excellent tuning.

Valentine

Main article: Valentine
For the 5-limit version, see Syntonic–31 equivalence continuum #Valentine (5-limit).

Valentine tempers out 126/125 and 6144/6125 as well as 1029/1024. It has a generator of ~21/20, three of which make the slendric generator ~8/7. 21/20 can be stripped of its 2 and taken as 3 × 7/5. In this respect it resembles miracle, with a generator of 3 × 5/7, and casablanca, with a generator of 5 × 7/3. These three generators are the simplest in terms of the relationship of tetrads in the lattice of 7-limit tetrads. Valentine can be described as the 31 & 46 temperament; its ploidacot is enneacot. 77edo, 108edo, or 185edo make for excellent tunings, which also happen to be excellent tunings for starling, the rank-3 temperament tempering out 126/125. Hence 7-limit valentine can be used whenever starling is wanted, with the extra tempering out of 1029/1024 having no discernible effect on tuning accuracy. Another tuning for valentine uses (3/2)1/9 as a generator, giving pure 3/2 fifths. Valentine extends naturally to the 11-limit, tempering out 121/120 and 441/440; 46edo has a valentine generator 3\46 which is only 0.0117 cents sharp of the minimax generator, (11/7)1/10.

Valentine has a very straighforward S-expression-based comma list in the 11-limit add-23 (i.e. the 2.3.5.7.11.23 subgroup) of {(S8/S10 = S22 × S23 × S24, S11), S21, S22, S23, S24}, so it is the temperament that equalizes the 20::25 segment of the harmonic series.

Superkleismic

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

Superkleismic tempers out the keema, 875/864, and can be described as the 15 & 26 temperament. It splits the ~7/4 into three ~6/5 generators of around 322 cents. This is noticeably sharper than the kleismic generator, hence the name.

In the 11-limit, two generator steps can be identified with ~16/11, and in the 13-limit, the same step can be treated as ~13/9. The S-expression-based comma list of 13-limit superkleismic is {S5/S6, S7/S8, S10, S12, (S21)}. Through careful observation of the equivalences therein one can derive the mapping of the full 13-limit.

Note that the generator is given as 6/5's octave complement, 5/3, in the data that follow, since a stack of 9 such generators octave-reduced is the perfect fifth; the ploidacot of superkleismic is wau-enneacot.

Superkleismic also sets two intervals of 21/20 equal to 10/9; as 10/9 = (20/19)⋅(19/18), we can identify 21/20, 20/19, and 19/18 together to add prime 19, tempering out 361/360 (S19) and 400/399 (S20). This structure is preserved within the entire superkleismic tuning range between 15edo and 26edo, while extensions for primes 13 and 17 bifurcate and are of higher complexity and lower accuracy.

41edo gives an obvious tuning in all the subgroups.

Unidec

Main article: Unidec

Unidec tempers out the ragisma, 4375/4374, and may be described as the 26 & 46 temperament. It has a semi-octave period and a generator of ~80/63, two of which minus a period make slendric's generator; its ploidacot is therefore diploid gamma-hexacot. In the 11-limit, the generator represents 14/11. 190edo makes for an excellent tuning in both the 7-limit and 11-limit.

Euslendric (2.3.7.13)

Forms of slendric in the most optimal range for the 2.3.7 temperament (36 & 77) lack an obvious strong mapping of prime 5 or prime 11. However, slendric can extend well to the no-fives no-elevens 29-limit by tempering out 273/272, 343/342, 378/377, 392/391, 513/512, and 729/728, or a comma basis defined in terms of S-expressions as {S7/S8, S14/S16, S15/S20, S24/S26, S27, S28}. 113edo is an obvious tuning.

Baladic (2.3.7.13)

Baladic is a 2.3.7.13.17-subgroup temperament that attempts to approximate the Maqam Sikah Baladi scale. It tempers out 169/168 (S13), which splits 7/6 in half (13/12~14/13) and one finds that the octave is therefore split in half via the interval 91/64, which is then equated to 17/12. 36edo is an excellent baladic tuning.
