Concertato

Concertato is a term in early Baroque music referring to either a genre or a style of music in which groups of instruments or voices share a melody, usually in alternation, and almost always over a basso continuo. The term derives from Italian concerto which means "playing together" —hence concertato means "in the style of a concerto." In contemporary usage, the term is almost always used as an adjective, for example "three pieces from the set are in concertato style."
