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!
