'''[[Ed6|Division of the sixth harmonic]] into 31 equal parts''' (31ED6) is very nearly identical to [[12edo|12 edo]], but with the [[6/1]] rather than the 2/1 being just. The octave is about 0.7568 [[cent]]s stretched and the step size is about 100.0631 cents.

== Division of 6/1 into 31 equal parts ==
== Theory ==
31ed6 is not a true xenharmonic tuning; it is a slightly stretched version (with an octave of 1200.8 cents) of the normal [[12edo]], similar to [[19ed3]]. It is very nearly identical to [[12edo]], but with the [[6/1]] rather than the 2/1 being just.


Note: 31 equal divisions of the hexatave is not a "real" xenharmonic tuning; it is a slightly stretched version (with an octave of 1200.8 cents) of the normal [[12edo|12-tone scale]], similar to [[19ED3]].

31ed6 is the 11th [[prime equal division|prime ed6]], following [[29ed6]] and before [[37ed6]].
