Caccini, Giulio
´lyō kät-chē´nē), c.1546–1618, Italian composer and singer. Both he and Peri composed settings of Ottavio Rinuccini's Euridice (1600), the earliest operas of which the music is extant. Nuove musiche (1601), a collection of his madrigals and arias, is the most important collection among the early examples of monodic style.
