Slashed double flat symbol
rvilarl opened this issue · comments
I was not able to find this symbol, is it supported? Please ignore the plus in pink.
I was also unable to find this ones as a single symbol, are they supported? Please ignore what is not green.
Where do these symbols come from? What accidental system are they part of?
Good question, they are part of vexflow.
@mscuthbert @AaronDavidNewman @ronyeh @sschmidTU @0xfe can you help?
To the first one I found the reference:
If I remember correctly (long ago) the slashed flat was a short-lived alternative form of quarter-tone flat. My vague impression is that it appeared in Ives or Cowell somewhere? It was superseded by the arrow-up/down versions (w/ or w/o the 4) and now almost completely replaced by the backwards flat version.
With this meaning, there's absolutely no reason for a double-half-flat -- one would use a normal flat.
I can't remember if I've seen the either of the latter two, but I can imagine that if the slashed half-flat was used (Turkish music now is coming to mind as another possible searching point?) then the doubled version could be useful, etc. But I think it's at a point where it would need a citation of usage to get it a code point. If it does, it'd probably be a stylistic alternate of other 3/4 sharps and 3/4 flats.
(I've never seen it before, but I do actually like this #+ style of 3/4 sharp as more graphically distinctive than the commonly used triple-crossed hash; like the db style 3/4 flat, it's sort of self explanatory)
They were contributed as individual glyphs by someone > 3 years ago. Maybe someone with more git skills than I can figure out who? Since we've moved the files around, the original contributors were lost.
I implemented them in Smoosic as 2.5 quarter tones, which is most likely nonsense since I wasn't able to find any information about them.
