Book excerpt: This second selection of studies by Frank D’Accone, again based principally on the documentary evidence, follows the development through the mid 16th century of musical chapels at the Cathedral and the Baptistery of Florence and of musical establishments at the Santissima Annunziata and San Lorenzo. The lives, careers and works of composers associated with these churches are illustrated and their works analyzed, particularly the theoretical treatise by Fra Mauro, the madrigals of Mauro Matti and the ambitiously conceived canzone cycle of Mattia Rampollini. The final studies, moving into the 17th century, look at the music for Holy Week, and the unprecedented programme of performances at Santa Maria Novella.
