Special noteheads for percussion or cue #249

Open clnoel opened 3 years ago

clnoel commented 3 years ago

A quick look did not find any issue that was about giving a note a "diamond" or an "X" or any other notehead other than the standard open/filled oval. This is going to be vital for representing percussion. This is the place for figuring out any kind of variation of noteheads from the standard closed/open/whole options, such as X, diamond, letter-note, cue-sized, colored, etc.

We might be able to do some of this this with SmufL codes on the notes, and we might also need to do some of this this in <part-layout> element if it needs to be combined in an odd way.

184 contains an interesting discussion about the use of Unicode characters to code accidentals. I think noteheads and accidentals should be handled similarly.

Is there any problem in following the MusicXML approach and using a <notehead> element?

joeberkovitz commented 3 years ago

@cecilios Yes, there is a problem at least for cue notes which are not merely a variation in notehead size/appearance, but have a semantic aspect as well: the notes in question are actually the part of another instrument and aren't intended for performance by the reader.

There is also a whole question of whether to incorporate cues by reference to a run of notes in some other part, instead of by value i.e. creating a duplicate copy of the other part's notes. Some notation programs support this.

I would suggest breaking out cues into a separate issue because of these important differences.

@joeberkovitz Thank you for the explanation. Then I understand that there are two issues:

  1. How to represent cue notes. I agree that a specific issue should be open.
  2. How to specify a different symbol for the notehead and how to inherit it from <part-layout>. I understand that this is the topic for this issue #249. If this is the case, the MusicXML approach works well for specifying the symbol, I didn't find any problem with it and also allows to specify a SMuFL glyph. But in any case I'm open to other solutions. As to how to inherit it ... an element <notehead-layout> analogous to the <stemming-layout>?

There is an existing cue-related issue: #102
