I'm afraid you can't understand this mail because of my poor English.
Please look at the picture at:

I'm writing a suite that consists of 3 movements (Holst's First Suite) .

I want to print the first movement on the first page , the second
movement and the third movement on the second page ,and the rest of
third movement on the third page.

So I wrote like this:

----------------------------------
\bookpart {
\header {
title = \markup {"First Suite in E" \super \flat "for Military Band"}
composer = \markup {"Gustav Holst"}
subtitle = "I. Chaconne."
}

\score {
<<
\new Staff \FirstMov
>>
}
}


\bookpart {
\header {
subtitle = "II. Intermezzo."
}

\score {
<<
\new Staff \SecondMov
>>
}
}

\bookpart {
\header {
subtitle = "III. March."
}

\score {
<<
\new Staff \ThirdMov
>>
}
}
----------------------------------
But on Lilypond's output there were the first movement on the first
page,the second movement on second page,the third movement on the
third and forth page.

What should I write?
Please tell me.
