Re: Four Bars per Line/System, again :)

Thanks, David.

There's been a long gap, in which I've been happily using the engraver for
jazz lead-sheets like this:

/% Concert Pitch version

#(define output-suffix "concert")
\book {
  \score {
    <<
      \PieceTranspose { \TheChords }
      \PieceTranspose { \TheHead }
    >>
    \layout {
      \context {
        \Score
        \consists #(custom-line-breaks-engraver '(4 4 4 4
                                                   3 4 4 4
                                                   4 4 4 4
                                                   4 4 4 4))
      }
    }
    \header {
      piece = \markup { \fontsize #-1 "Concert" }
    }
  }
}
/

...but with additional "\book"s for Bb and Eb instruments. I'd like to be
able to avoid the potential for error in dealing with the odd line which
needs to be other than 4 bars long by defining the "4 4 4 4 3 4 ..." as a
variable and then passing the variable to custom-line-breaks-engraver but I
can't work out how to do this.

Regards,

Michael
