By 1560 he had come to northern Italy, where he held a succession of mostly short posts; there are gaps in the record for some portions of his career.
On January 1, 1562, he became maestro di cappella, music director, of the prestigious Accademia Filarmonica of Verona, succeeding Francesco Portinaro, who had held the post the preceding year.
In 1565 he was in Vicenza; 1566, Treviso; and he held a longer post as maestro di cappella in Udine from 1567 to 1570, and then again from 1574 to 1577, though his whereabouts between 1570 and 1574 are unknown.
He dedicated his first book, Il primo libro di madrigali for five voices, to the Count of Salò, Giberto Sanvitale, and the next book, Il primo libro di madrigali for four voices, to Gian Giacomo Trivultio.
