A.4.2 String quartet parts

The “String quartet template” snippet produces a nice string quartet, but what if you needed to print parts? This new template demonstrates how to use the \tag feature to easily split a piece into individual parts.

You need to split this template into separate files; the filenames are contained in comments at the beginning of each file. piece.ly contains all the music definitions. The other files – score.ly, vn1.ly, vn2.ly, vla.ly, and vlc.ly – produce the appropriate part.

Do not forget to remove specified comments when using separate files!

%%%%% piece.ly
%%%%% (This is the global definitions file)

global= {
  \time 4/4
  \key c \major
}

Violinone = \new Voice { \relative c''{
  \set Staff.instrumentName = #"Violin 1 "

  c2 d e1

\bar "|." }}   %*********************************
Violintwo = \new Voice { \relative c''{
  \set Staff.instrumentName = #"Violin 2 "

  g2 f e1

\bar "|." }}   %*********************************
Viola = \new Voice { \relative c' {
  \set Staff.instrumentName = #"Viola "
  \clef alto

  e2 d c1

\bar "|." }}   %*********************************
Cello = \new Voice { \relative c' {
  \set Staff.instrumentName = #"Cello "
  \clef bass

  c2 b a1

\bar "|."}}   %**********************************

music = {
  <<
    \tag #'score \tag #'vn1 \new Staff { << \global \Violinone >> }
    \tag #'score \tag #'vn2 \new Staff { << \global \Violintwo>> }
    \tag #'score \tag #'vla \new Staff { << \global \Viola>> }
    \tag #'score \tag #'vlc \new Staff { << \global \Cello>> }
