160edo: Difference between revisions

Line 1:

~~'''160edo''' is the [[~~EDO|~~equal division of the octave]] into~~ 160 ~~parts of exact 7.5 cents each.~~

It is closely related to [[80edo]], but the patent ~~vals~~ differ on the mapping for 7. It is [[contorted]] in the 5-limit, tempering out [[2048/2025]] (diaschisma) and 390625000/387420489 (quartonic comma).

160edo is closely related to [[80edo]], but the [[patent val]]s differ on the mapping for 7. It is [[contorted]] in the 5-limit, tempering out [[2048/2025]] (diaschisma) and 390625000/387420489 (quartonic comma).

Using the [[patent val]] {{val| 160 254 372 449 554 592 }}, it tempers out [[245/243]], [[6144/6125]], and 3176523/3125000 in the 7-limit; [[441/440]], [[2200/2187]], [[4000/3993]], and 6912/6875 in the 11-limit; 196/195, 325/324, 352/351, 832/825, and 3146/3125 in the 13-limit.

Line 9:

Using the 160ce val {{val| 160 254 '''371''' 449 '''553''' 592 }}, it tempers out [[1638400/1594323]] and 2197265625/2147483648 in the 5-limit; [[875/864]], [[2401/2400]], and 2097152/2066715 in the 7-limit; [[896/891]], 3388/3375, 4125/4096, and 12005/11979 in the 11-limit; 275/273, 572/567, 847/845, 1573/1568, and 3185/3168 in the 13-limit.

As every other step of [[320edo]], a comprehensive full 19-limit system, 160edo might make more sense as a 2.9.7.13.17 subgroup temperament, where it tempers out [[729/728]], [[833/832]] and [[5832/5831]].

Since 160 factors into 2<sup>5</sup> × 5, 160edo has subset edos {{EDOs| 2, 4, 5, 10, 16, 20, 32, 40, and 80 }}.
