Emilio de' Cavalieri was an Italian composer and organiser of court spectacles active from the 1580s until his death in 1602, associated with late Renaissance and early Baroque sacred and secular vocal music. He employed emerging monodic and recitative techniques in intermedi and sacred drama, and his staged sacred work Rappresentatione di Anima et di Corpo is regarded as part of the cultural shift from Renaissance polyphony to early Baroque theatrical and devotional forms.
