Anyway, the character selection window for accidentals only shows 136 at the time but there's a character range menu that has a list that starts like this: 1: U+0...U+7F 2: U+80...U+FF 3: U+100...U+17F and so on; there are 512 ranges like that on the menu. However, on none of them can I see any more Sagittal symbols when the Bravura font has been selected - only in the first 'range'.
That's very strange, because when I install Mus2 and go to Score > Symbols, click the Add button, select "New Accidental", click Acquire from Font, select Font: Bravura and Character Range: 456: U+E380...U+E3FF, I see the expected Sagittals.
Incidentally, you can get to that character range quickly by clicking in the Character Range field and typing "456↵" with no pause between digits. The more common Sagittals are in Character Range: 455: U+E300...U+E37F.
About the notation. So 15edo is notated as three circles of fifths a syntonic comma apart where the tuning is such that the fifth is 720 cents and the syntonic comma is so big that it's close to a 12edo half-step, ie. 80 cents? A Pythagorean third, then is 480 c, enharmonically a fourth, and when that's narrowed by the comma, we'll get a "5/4" of 400 cents (as it's also tuned in 12et). Yes?
Yes. That is all correct. Of course this is only one way of notating these 5n edos—the way that William asked for. They could instead be notated as subsets of 60-edo. In that case the notational fifth would be 700c as in 12edo.
So, what's the rationale behind the 35M diesis symbol in 10edo?
Gai
is actually being used there in its secondary role as the 13 M-diesis symbol (or you can say we dropped the accent mark), because 10edo has a very good (within 0.5 cent) approximation of 13/8, at 7 degrees, e.g. C : A
. Strictly-speaking, in that example it is behaving as the 13 L-diesis (26:27) but in 10edo both 13M and 13L map to 1 degree, so we only need the one 13 symbol.
