I am writing a score that has a few notes with cross heads. It would be
helpful to define \cross such that
\cross { c8 c8 c8 }
would expand to:
\override NoteHead.style = #'cross
c8 c8 c8
\revert NoteHead.style
Is that possible?
Yes:
cross =
#(define-music-function (parser location music)(ly:music?)
#{
\temporary\override NoteHead.style = #'cross
$music
\revert NoteHead.style
#}
)
{
\cross { c8 c8 c8 }
}
(I don't know when (recently) the \temporary was included (I think
somewhere in 2.17). This ensures that NoteHead.style won't be reverted
to its _default_ value but to the value that was active _immediately
before_.
