It works for me if I put it in a \header in the score block

Paul thanks for that (and Eluze)..
However breakbefore still seems rather vague on what it supposed to do.
For example
\book {
\header { title = "Hello" }
\score {
\repeat unfold 10 { e'' e'' e'' e'' }
\header { breakbefore = ##t }
}
\score {
\repeat unfold 10 { b' b' b' b' }
}
}
Gives me a 'Hello" on its own and then score starts on the next page, and the
next score on the next page. So I get 3 pages in total.
However if I move the \header { breakbefore = ##t } anywhere else from this
specific place I get an 'unexepcted \header' error.. for instance:
\book {
\header { title = "Hello" }
\score {
\header { breakbefore = ##t }
\repeat unfold 10 { e'' e'' e'' e'' }
}
\score {
\repeat unfold 10 { b' b' b' b' }
}
}
The header is still inside the \score { } but this fails.
Also if I put it in the second \score construct like so:
\book {
\header { title = "Hello" }
\score {
\repeat unfold 10 { e'' e'' e'' e'' }
}
\score {
\repeat unfold 10 { b' b' b' b' }
\header { breakbefore = ##t }
}
}
I get the title on the page 1 with the first score and the second score on a
new page - 2 pages instead of 3.
If I add a second 'header' making the assumption that the breakbefore will
break the *previous* header, then this:
\book {
\header { title = "hello" }
\score {
\repeat unfold 10 { e'' e'' e'' e'' }
\header { title = "goodbye" }
}
\score {
\repeat unfold 10 { b' b' b' b' }
\header { breakbefore = ##t }
}
}
Outputs the same as the one previous (I get no "goodbye" in my title).
If I try to move my real header inside the \score { }
\book {
\score {
\repeat unfold 10 { e'' e'' e'' e'' }
\header { title = "goodbye" }
}
\score {
\repeat unfold 10 { b' b' b' b' }
\header { breakbefore = ##t }
}
}
Then I get 2 pages but no titles at all.
So I really don't know what use this is as
1. It only allows one \header { } title to be displayed - even if you add
different \header { } components (i.e. poet = or instrument = etc) they don't
print.
2. You must put the \breakbefore in a *very* specific place else it does
nothing or gives you a compilation error. You cannot just put it 'anywhere'
inside the score and you have to put it in the 'first' and then in a place
after the notes.
So I'm struggling to see the point of this breakbefore and wonder if anyone
really uses it in this context.
James
