I have a bunch of repeated things like this
d f \mark \markup \italic \magnify #0.7 "(tenor & trp.)" r16
where I put a little instruction over the melody
I'd like to have a little function to call instead of \mark \markup \italic \magnify #0.7 "blah", with the "blah" as a parameter.
So I tried this
#(define-markup-command (instruct layout props text ) (markup?)
(intepret-markup layout props
\markup \italic \magnify #0.7 #text
and then put this in my code
d f \mark \instruct "(tenor & trp.)" r16
But it doesn't like it!
I am sure this is very easy, and maybe I should be using a music-function instead of the markup command definition.
Can someone help me?
