### 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. Les musiciens sont maintenant habitués aux barres de mesure, ce qui n’était pas le cas à l’époque. Dans une forme de compromis, les barres de mesures sont souvent imprimées entre les portées, mise en forme que l’on appelle « lignes de mensuration ».
