I recently tried a music function like this. I wanted it to return a score,
but I always got:
error: music function cannot return #<Score>
I wonder whether music functions can return a score at all, or whether I'm
just doing something wrong? Here's a simple example that produces that error
for me:
\version "2.18.0"
scoreSetup =
#(define-music-function
(parser location letter)
(string?)
#{
\score {
{ a b c d }
}
#})
\scoreSetup "K"
