no:
- music is already a music object, so no need for make-music.
- let returns the value of the last expression, read any scheme manual for
details.
So if you want to do side-effects, you'll want do do something like:
(define-music-function (variables)
(let ((music #{ LilyPond code #}))
(other Scheme code)
music))
