Re: define \header

[address@hidden]

Ok, I'll try to clarify:

First off, Marek is correct, \header can appear within \score{} and is useful 
especially when printing all headers as I'm doing.

My initial music input files essentially look like this:


one-global = \relative {
  <key/clef/repeats/etc>
}

one-first = \relative c' {
   <top part music>
}

one-second = \relative c' {
  <second part music>
}

one-third = \relative c' {
  <third part music>
}

one-fourth = \relative c {
  <bottom part music>
}

The second chorale is in the same file.  The above blocks are the same except 
that they start with 'two-'

My score definitions are in another file:

chor-one = {
  \context StaffGroup <<
    \new Staff <<
      \one-global
      \context Voice = "first"  <<
        \voiceOne \one-first
      >>
      \new Voice = "second" <<
        \voiceTwo \one-second
      >>
    >>
    \new Staff <<
      \one-global
      \context Voice = "third"  <<
        \voiceOne \one-third
      >>
      \new Voice = "fourth" <<
        \voiceTwo \one-fourth
      >>
    >>
  >>
}

Again, the next chorale's score block has 'one-' replaced with 'two-' (except 
at the top of the block where it's '-two' instead of '-one')

So far, so good.

Now, the file which is actually going to produce the PDF:

\book {
  \paper {
    print-all-headers = ##t
  }
  \bookpart {
    \score{
      \chor-one
      \header {
        title = "Title 1"
        subtitle = "Subtitle 1"
        composer = "Composer 1"
        }
    }
    \score{
      \chor-two
      \header {
        title = "Title 2"
        subtitle= "Subtitle 2"
        composer = "Composer 2"
      }
    }
    \paper {
      page-count = #1
    }
  } %% end bookpart
}


The above series of files work just fine but I would like to move the actual 
header information out of this file.  If I put it in the score blocks in the 
second file I get syntax errors.  I had thought that since I could have the 
\header block inside a score block I could simply keep it with the defined 
score block.  Evidently I was wrong.

Is there a way of doing this?

I still don't have a sufficient picture of your material,
but you may try another approach:

If your initial concern was to clean up the 'master' .ly file you may:
- define each chorale in one file:
  - write your music definitions
  - write a \header block
  - write a \score block
- In the master file you can \include the individual chorale files so you have 
only one line per chorale.

Of course the included chorale doesn't have to be completely defined in one 
single file but can also use includes.

One question that isn't clear from your initial post:
Do you write the \score blocks manually for each chorale?
Or do you have a default block that you include?
