Giulio Romolo Caccini (also Giulio Romano) was an Italian composer, teacher, singer, instrumentalist and writer of the very late Renaissance and early Baroque eras. He was one of the founders of the genre of opera, and one of the single most influential creators of the new Baroque style. He was also the father of the composer Francesca Caccini. Caccini wrote music for three operas—Euridice (1600), Il rapimento di Cefalo (1600, excerpts published in the first Nuove Musiche), and Euridice (1602), though the first two were collaborations with others (mainly Peri for the first Euridice). In addition he wrote the music for one intermedio (Io che dal ciel cader farei la luna) (1589). No music for multiple voices survives, even though the records from Florence indicate he was involved with polychoral music around 1610. He was predominantly a composer of monody and solo song accompanied by a chordal instrument (he himself played harp), and it is in this capacity that he acquired his immense fame. He published two collections of songs and solo madrigals, both titled Le nuove musiche, in 1602 (new style) and 1614 (the latter as Nuove Musiche e nuova maniera di scriverle). Most of the madrigals are through-composed and contain little repetition; some of the songs, however, are strophic. Among the most famous and widely disseminated of these is the madrigal Amarilli, mia bella.
