Italian composer. A pupil of Palestrina whom he succeeded as rnaestro di cappella at S. Maria Maggiore in Rome, he later held similar posts at S. Luigi dei Francesi (from 1375) and the Sistine Chapel (from 1604) and was also a Papal singer. In 1580 he started a music school, where the composition teachers included Palestrina as well as himself and his brother Giovanni Bernardino Nanino. One of the best of the Roman composers who adopted the Palestrina style, he published madrigals, canzonets and church music; his remarkable set of 157 counterpoints and canons in up to eleven parts on a cantus firmus by Costanzo Festa survives in MS.
