I compile a large song book, and for that I would like to have many local definitions of functions, that will, in the end, be in an \include d file, but that makes no difference here. For this, I need to define the functions inside \score{ ... } scope. However, LilyPond keeps throwing errors.
The non-working example:
\version "2.17.26"
\book {
\header {
title = "This is a book"
}
\score {
xyz = { a' b' c'' }
abc = #(define-music-function
( parser location musicnotes )
( ly:music? )
#{
c' $musicnotes e'
#}
)
{ \abc { d' } f' \xyz }
\header {
piece = "First piece"
opus = "op. 1024"
}
}
\score {
xyz = { a' a' a' }
abc = #(define-music-function
( parser location musicnotes )
( ly:music? )
#{
e' $musicnotes c'
#}
)
{ \abc { d' } f' \xyz }
\header {
piece = "Second piece"
opus = "op. 1025"
}
}
}
Throws an error:
test.ly:10:17: error: unrecognized string, not in text script or \lyricmode xyz = { a' b' c'' }
The following works, however, I have to give the functions unique names, which is frowned upon.
\version "2.17.26"
xyz = { a' b' c'' }
abc = #(define-music-function
( parser location musicnotes )
( ly:music? )
#{
c' $musicnotes e'
#}
)
xxyz = { a' a' a' }
aabc = #(define-music-function
( parser location musicnotes )
( ly:music? )
#{
e' $musicnotes c'
#}
)
\book {
\header {
title = "This is a book"
}
\score {
{ \abc { d' } f' \xyz }
\header {
piece = "First piece"
opus = "op. 1024"
}
}
\score {
{ \aabc { d' } f' \xxyz }
\header {
piece = "Second piece"
opus = "op. 1025"
}
}
}
