Although musical drama, such as The Play of Daniel (12th cent.), had previously existed, it was in the year 1600 that opera came into being. It began in Florence, Italy, fostered by the camerata [society], a group of scholars, philosophers, and amateur musicians that included the librettist Ottavio Rinuccini (1562-1621) and the composers Vincenzo Galilei , Emilio del Cavaliere (c.1550-1602), Jacopo Peri , and Giulio Caccini . It was their aim to promote the principle of monodic musical declamation, i.e., a single melodic line with modest accompaniment inspired by the example of ancient Greek drama; accordingly, the earliest operas took their plots from mythology, the legend of Orpheus and Eurydice being one of the most popular.
Because the story hinges on the expressive power of music and solo song, the early composers referred to their work as dramma per musica [drama through music], and operas of the 17th and 18th cent. used myth at first and plots about historical figures later. It had both lofty and comic strains, which were in time separated into distinct genres, the opera seria (serious opera) and the opera buffa (comic opera). Although fragments of Jacopo Peri's Dafne (c.1597) exist, the same composer's Euridice (1600), set to verse by Ottavio Rinuccini, is generally considered the first opera.
