Talk:Essential tempering comma
This page also contains archived Wikispaces discussion.
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.
Can anyone check it out? FloraC (talk) 14:44, 7 January 2022 (UTC) -- Updated FloraC (talk) 12:28, 11 March 2022 (UTC)
Not a definition, but a derivation?
It seems it's more appropriate to label Gene's formula a method, or a derivation to approach what it intends to find. Editing the page accordingly. FloraC (talk) 13:21, 11 March 2022 (UTC)
