Wait a second, then why can't we just do something like this:

143 NOTECOMMAND     \\({A}|{N}|[-_])+

I'm sure I don't have it quite right, but it's the idea I'm
interested in. Then we could do this:

"violin1" = { c''4 }
"violin2" = { c'4 }

\score <<

I must be missing something, because this looks way too easy.
Could this idea work (if coded the right way)?
