Patron and composer. Sponsored and participated in practical discussions and experiments that led to the beginnings of opera. Giovanni de' Bardi, whose Camerata was more concerned with theoretical and philosophical matters, had moved to Rome in 1592, leaving Corsi the most prominent patron of music in Florence after the Medicis. With Jacopo Peri he composed the musical setting of Ottavio Rinuccini's Dafne, first performed in 1598 (only a few excerpts survive, two definitely by Corsi). In 1600 he sponsored and played harpsichord in the first performance of Peri's Euridice.
