The '''96 equal divisions of the octave''' ('''96edo''') divides the octave into 96 equal parts of exactly 12.5 [[cent]]s each. | The '''96 equal divisions of the octave''' ('''96edo''') divides the octave into 96 equal parts of exactly 12.5 [[cent]]s each. | ||

As a [[ | As a [[5-limit]] system, 96edo can be characterized by the fact that it tempers out both the [[Pythagorean comma]], 531441/524288, [[Würschmidt's comma]], 393216/390625, the unicorn comma, 1594323/1562500, and the kwazy comma, {{monzo| -53 10 16 }}. It therefore has the same familiar 700-cent fifth as [[12edo]], and has a best major third of 387.5 cents, a bit over a cent sharp. There is therefore nothing to complain of with its representation of the 5-limit and it can be recommended as an approach to the [[Würschmidt family]] of temperaments. It also tempers out the unicorn comma, and serves a way of tuning temperaments in the [[unicorn family]]. | ||
In the [[ | In the [[7-limit]], 96 has two possible mappings for 7/4, a sharp one of 975 cents from the patent val, and a flat one of 962.5 cents from 96d. Using the sharp mapping, 96 tempers out 225/224 and supports 7-limit [[würschmidt]] temperament, and using the flat mapping it tempers out 126/125 and supports [[worschmidt]] temperament. We can also dispense with 7 altogether, and use it as a no-sevens system, where it tempers out [[243/242]] in the 11-limit and [[676/675]] in the 13-limit. If we include 7, then the sharp mapping tempers out [[99/98]] and [[176/175]] in the 11-limit, and [[169/168]] in the 13-limit, and this provides the optimal patent val for the [[Marvel temperaments #Interpental|interpental temperament]]. With the flat 7 it tempers out [[385/384]] in the 11-limit and [[196/195]] and [[364/363]] in the 13-limit, and serves for the various temperaments of the unicorn family. | ||

Since 96edo has a step of 12.5 cents, it also allows one to use its MOS scales as circulating temperaments. It is the first 12''n''-edo which does this and the first edo which allows one to use an MOS scale with a step 20 degrees or larger as a circulating temperament{{clarify}}. | Since 96edo has a step of 12.5 cents, it also allows one to use its MOS scales as circulating temperaments.
