GNU LilyPond – Manuel d'initiation: A.7.1 Transcription de musique mensurale

### A.7.1 Transcription de musique mensurale

Dans le cadre de la transcription de musique mensurale, un « incipit » en début de pièce permet d’indiquer tonalité et tempo originaux. Si les musiciens sont aujourd’hui habitués aux barres de mesure qui mettent en évidence la structure rythmique, elles n’étaient pas courantes à l’époque – le mètre variait souvent après quelques notes. Dans une forme de compromis, les barres de mesures sont régulièrement imprimées entre les portées.
