Italian composer. In 1511 he became choirmaster at Florence cathedral and baptistery, and a few years later was made a member of the Papal choir by the Medici Pope Leo X. In 1520 he settled in Rome as a Papal diplomat and informer. He is noted for his volume of Petrarch settings of 1520, the first that Petrucci published of a single Italian composer's works and an important document of the emerging madrigal style in its experimentation with freer poetic forms and imitative writing. Other secular works and Lamentations of his survive in Florentine manuscripts.
