Major second: Difference between revisions

Line 219:

* The generator of the 7L 1s scale can be interpreted as a [[10/9]] major second, that is equated to [[11/10]] and [[12/11]] [[neutral second]]s by [[porcupine]], so that three generators reach [[4/3]]. Its tuning range is therefore somewhat ambiguous between major and neutral second.

* The generator of the 6L 1s and 7L 6s scales can be interpreted as a 10/9 major second in [[tetracot]], where four of these seconds reach [[3/2]].

* The generator of the 6L 1s and 7L 6s scales can be interpreted as a 10/9 major second in [[tetracot]] (and sometimes equated to [[11/10]]), where four of these seconds reach [[3/2]].

* The generator of the 6L 1s and 6L 7s scales can be interpreted in terms of [[2.5.7 subgroup|2.5.7]] [[didacus]], whose generator represents [[28/25]] and which splits the septimal tritone [[7/5]] in three, with one step making the generator 28/25 and two making [[5/4]]. This generator can also stand in for 10/9 and [[9/8]] in the 2.9.5.7 [[subgroup]], if it is treated as an index-2 restriction of [[septimal meantone]].

* The generator of the 5L 6s scale can be interpreted as [[8/7]] in [[2.3.7 subgroup|2.3.7]] [[slendric]], where three of them are equated to 3/2.
