The '''Delta scale''' is the equal division of the classic diatonic semitone ([[16/15]]) into eight parts of 13.9664 cents each, corresponding to 85.9204 [[edo]]. It is [[inconsistent]] to the 5-limit and higher, as the [[direct approximation]]s of 3/2, 5/4, and 6/5 are the 50th, 28th, and 23rd steps, respectively (and 28 + 23 ≠ 50).

English Wikipedia has an article on:

The Delta scale is the equal division of the classic diatonic semitone (16/15) into eight parts of 13.9664 cents each, corresponding to 85.9204 edo. It is inconsistent to the 5-limit and higher, as the direct approximations of 3/2, 5/4, and 6/5 are the 50th, 28th, and 23rd steps, respectively (and 28 + 23 ≠ 50).

Lookalikes: 86edo, 136edt, 50edf
