So it sounds like this is a "history of music notation" question, rather 
than a character encoding question. And it looks like this is just 
passing on the question from @gro-tsen.bsky.social, rather than asking a 
different question. Is this the question to be passed on to the W3C 
Music Notation Community Group and the MEI group?

Who wants to hear the reply?  If it is @gro-tsen.bsky.social, and if the 
person who knows the answer is not on BlueSky, to whom do they reply?

If I know how to reply, I can pass on a question like this:
