Italian composer best known for his madrigal-comedy (madrigal comedy) L'Amfiparnaso and other entertainment music.

Vecchi served as maestro di cappella at the cathedrals of Salò and Modena and as canon at Correggio cathedral before his appointment as maestro at the Modena ducal court (1598). Vecchi composed masses, motets, canzonets, and madrigals. His most original work, L'Amfiparnaso (1597), which has been called a “madrigal opera,” is a set of 15 pieces, dramatic in nature but not intended to be staged. Although this work stands entirely apart from the path opera was to take, Vecchi's sense of drama and contrast made him a pioneer of dramatic music.
