I suppose you could use a music property, but you wouldn't add it to
this object's definition.

A good example would be afterGraceFraction, which is basically an
identifier \afterGrace accesses via parser lookup.  Of course, what I
said earlier about using such variables is incorrect: you *can* change
them within music, as long as you use define or set! (the docs for
\afterGrace use define, but it would make more sense to use set!,
since afterGraceFraction is already defined in
music-functions-init.ly).
