Diamond-mos notation: Difference between revisions

Line 100:

* There’s an exception to the rule that diamond-mos notation is always based on an edo. There is also the option of specifying a mos tuning which does not come from an edo. At the top of the score, write “Non-edo mos tuning” and specify the exact size of the generator. Instead of writing the mos mode in edosteps, use generic mos pattern notation, e.g. “LLsLsLs”. When using non-edo notation, ^/v have no meaning and are disallowed. The only available accidentals are the mos-based &/@/e/a accidentals (or #/b/t/d if using 5L 2s). Since non-edo notation doesn’t use a fixed, finite set of pitches, retuning to an arbitrary scale is disallowed.

* It is acceptable to treat equal scales (sub-edos of the edo used for notation) as mosses for notation in diamond-mos, for example 9edo in 18edo. In that case, &/@ have no meaning and are disallowed. There are also no boxes on the staff. The only non-~~modmos~~ key signatures allowed are all-up (^) key signatures or similar.

In that case, &/@ have no meaning and are disallowed. There are also no boxes on the staff. The only non-altered key signatures allowed are all-up (^) key signatures or similar.

* It is acceptable to use 5L 2s-based notation even for edos where the best fifth is 4\7 or 3\5. This is for consistency with existing microtonal notation that allows this. In the case of 4\7, #/b technically alter notes by zero edosteps, so they’re disallowed. [[TAMNAMS#Step ratio spectrum|Equalized]] and [[TAMNAMS#Step ratio spectrum|paucitonic]] tunings are only allowed for 5L 2s, not other mosses.
