Italian composer, brother and pupil of Giovanni Maria Nanino. Maestro di cappella at S. Luigi dei Francesi in Rome from 1591 to 1608 and later at S. Lorenzo in Damaso; taught at his brother's music school in Rome where his pupils included his son-in-law, Paolo Agostini, and Allegri. He published 5-part madrigals and church music, including small-scale motets; he was one of the first Roman composers to use the basso continuo, but though his music is of high quality, his reputation is overshadowed by that of his better-known brother.
