Italian composer. A pupil of Palestrina, whom he succeeded in 1594 as maestro di cappellaat St Peter's, Rome, he also held similar posts at S. Luigi dei Francesi, the German College and, from 1614, the Sistine Chapel. His many books of madrigals, villanellas and canzonets were much reprinted, but he is in fact more notable for his church music, most of which survives in manuscript, though he did publish two volumes of motets.
