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.
