Revision as of 12:32, 9 September 2025

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 gravity family of temperaments tempers out the graviton (monzo: [-13 17 -6⟩, ratio: 129140163/128000000).

Gravity

Main article: Gravity

The generator for the gravity temperament is a grave fifth of ~40/27, and hence the name. However, the functional generator is the acute fourth of ~27/20, six of which reach the 6th harmonic; the ploidacot for gravity is beta-hexacot. Gravity is part of the syntonic–chromatic equivalence continuum with n = 6, so it equates a Pythagorean apotome with a stack of six syntonic commas.

Overview to extensions

Full 7-limit extensions of gravity include marvo (65d & 72), zarvo (65 & 72), gravid (58 & 65), and harry (58 & 72), all considered below. A notable subgroup extension is larry.

There is also an unnamed 58 & 65d extension by tempering out 176/175 to extend larry to include prime 7 and tempering out 847/845 to extend it to the 13-limit, with an S-expression-based comma list of {S8/S9, S9/S10, S10/S11, (S11/S13,) S12}.

Harry

Main article: Harry

Harry adds the breedsma, 2401/2400, and the cataharry comma, 19683/19600, to the set of commas, and may be described as the 58 & 72 temperament. The period is half an octave, and the generator ~21/20, with generator tunings of 9\130 or 14\202 being good choices. Mos of size 14, 16, 30, 44 or 58 are among the scale choices.

It becomes much more interesting as we move to the 11-limit, where we can add 243/242, 441/440 and 540/539 to the set of commas. 9\130 and especially 14\202 still make for good tuning choices.

Similar comments apply to the 13-limit, where we can add 351/350, 364/363, and 729/728 to the commas. 130edo is again a good tuning choice, but even better might be tuning the harmonic 7 justly, which can be done via a generator of 83.1174 cents. 72 notes of harry gives plenty of room even for the 13-limit harmonies.
