Override Notehead on Beam?

[nicholasjconn]

I'm trying to render the Raindrop Prelude and am running into a problem. I can't figure out how to render a half note on the beam (see image below).

Any suggestions? Would it be possible to create it with all eighth notes and then override the glyphs somehow to render as a half note?

Perhaps you can use glyphnote

perhaps you can use glyphnote

There's no way to set the head directly? We could add the 'normal' note heads to Tables.customNoteHeads, then it would work like notehead_tests.

btw @nicholasjconn what is the interpretation of this custom note head? I've not seen it before. I've seen diamond note heads for tremolo.

I went down the rabbit hole and was able to get it to work. In EasyScore, creating a new 'valid code' and then adding it to Tables.durationCodes. This table is kind of a mess - you have to add it for each duration. IMO there should be a more general way of handling note heads.

beam_tests.ts

const voice = score.voice(
    [
    ...
      beam(notes('(cb4 e#4 a4)/8/z, (d4 f4 a4)/8, (ebb4 g##4 b4)/8, (f4 a4 c5)/8', { stem: 'up' })),

tables.ts:

const durationCodes: Record<string, any> = {
...
  '8': { // just for eighth notes
     type: {
...
       z: {code_head: 'noteheadHalf'}

@AaronDavidNewman this last two examples are more related to sharing stem on formatter, are not they?

[AaronDavidNewman]

I'm glad this helped. Feel free to submit a PR if you think this will be generally useful. Maybe we should use a different letter instead of 'z' - maybe 'o' for open? And it can be added to all the closed-note durations (>= '8') in durationCodes.

It should work like your second example if you use a second voice. @rvilarl is it possible to get the head to go in the other direction? I could manually if I create the StaveNote directly but not with easy score.

[AaronDavidNewman]

@rvilarl you're right that would be sharing stem. I was just thinking that voices should do that automatically if they share a note with different duration that starts in the same place.

[rvilarl]

I think that there is a condition that checks that the duration is the same to allow sharing the stem. I will have a look.

I'll plan to create a PR for it sometime in the next few weeks. I'm working on the first release of my app and am moving forward with my workaround for now. Thank you both again.
