Definition still wrong
Despite my earlier attempt to frame Gene's definition for identifying essentially tempered triads (and excluding tetrads), now I find it also fails this task.
For example, 121/120 induces essentially tempered triads. One of them is 1-11/8-5/3 with steps 11/8-11/9-6/5. Although 11/10 and 12/11 are interchangeable in the chord construction, 11/8 and 15/11 aren't since 11/8 is 11-odd-limit and 15/11 isn't, which constitutes the source of the tempering essence.
Further investigation suggests that the definition is probably a sufficient (and not necessary) condition for identifying essentially tempered chords.
My revised definition:
- There are three ratios r1, r2, and r3 in S such that c = r1r2/r3, and
- cnri is not a member of S for i = 1, 2, 3, where n is a nonzero integer.
