Definition column[edit]

Definition	Legend
c	syntonic comma
D	diesis
x	lesser chromatic semitone
Λ	Pythagorean minor second
X	greater chromatic semitone
S	(small) limma
L	large limma
t	lesser tone
T	greater tone

The use of "Pythagorean Minor Seventh" as a label for one of the ordinary minor sevenths is misleading. I don't want to simply edit it away, since it is linked to another page. But a far better name for the two ordinary minor sevenths would be as parallels to the two ordinary major seconds: greater minor seventh complement of lesser tone and lesser minor seventh complement of greater tone. The 'greater minor seventh' is found in any simple diatonic (just) scale between MI and RE. The 'lesser minor seventh' is found between SOL and FA.

This article lacks a key or an explanation for the Definition column, and I don't know enough to complete it 66.108.39.64 (talk) 04:02, 27 October 2010 (UTC)Alan[reply]

The table itself explains the "definition" column, though it may be poorly named (perhaps "construction"?). I added the table to the right, which makes a more direction connection between the names and the letters. I'll try bolding the individual letters ("T") to make them stick out from the addition and subtraction ("T-t"). Hyacinth (talk) 05:49, 19 August 2015 (UTC)[reply]

RE: "The table below shows how these steps map to the first 31 scientific harmonics, transposed into a single octave."[edit]

It is perhaps too misleading to find intervals in the overtone series ("31 scientific harmonics") that are close to 5-limit just intonation intervals and then take the interval name from the 5-limit table and apply it to the approximate overtone interval. Is that table really necessary or desirable? I'd propose deleting it, or moving it to another page that is dedicated to the overtone series.
