GNU LilyPond – Manuel d'initiation: A.6.1 Orchestre, chœur et piano

### A.6.1 Orchestre, chœur et piano

Ce canevas illustre l’utilisation de contextes `StaffGroup` pour regrouper les instruments selon leur famille, imbriqués dans un `GrandStaff`, ainsi que le recours à la fonction `\transpose` pour les instruments transpositeurs. Dans tous les identificateurs, la musique est stockée en ut. Les notes peuvent tout aussi bien être saisies en ut ou dans la tonalité particulière de l’instrument avant d’être transposées puis affectées à une variable.
