However, why jump through such Scheme hoops when LilyPond syntax is more
direct?
Thank you Aaron. I used a misleading topic, sorry. I wanted a set of layout properties which is shared by all the scores I edit. So I can simply import it with \include.
I thought that it was necessary to replicate these props in all the layout blocks of all the scores. Then I asked for a "Scheme solution"
But this is not true:
%%%%%%%%%%%%%%%
\version "2.19.45"
\layout {
\context {
\Staff
\override StaffSymbol.color = #red
}
}
\layout {
\context {
\Staff
\override StaffSymbol.line-count = 3
}
}
<< \new Staff { b'4 } \new Staff { b'4 } >>
%%%%%%%%%%%%%%%
