(b Florence, c.1480; d after 1545). Italian theorist. He claimed to have been associated with Josquin, Obrecht, Isaac, and Agricola while in Florence. From about 1516 he was a priest at Imola, where he remained until 1522. He then served as maestro da casa in the household of Sebastiano Michiel in Venice before entering the monastery of S. Leonardo at Bergamo in 1536. Although his writings on music were largely influenced by earlier theorists such as Tinctoris, he made a valuable contribution to modal theory and was the first to apply the system of eight modes to polyphonic music in his Trattato (Venice, 1525). His explanations of counterpoint are considered to be the best of those in the generation before Zarlino.
