Book excerpt: Claudio Monteverdi (1567-1643) is well known as the composer of the earliest operas still performed today. His Orfeo, Il Ritorno d'Ulisse in Patria, and L'incoronazione di Poppea are internationally popular nearly four centuries after their creation. These seminal works represent only a part of Monteverdi's music for the stage, however. He also wrote numerous works that, while not operas, are no less theatrical in their fusion of music, drama and dance. This is a survey of Monteverdi's entire output of music for the theatre - his surviving operas, other dramatic musical compositions, and lost works.
