A part song — or part-song or partsong — is a form of choral music which consists of a secular song which has been written or arranged for several vocal parts, commonly SATB choir, but also for an all-male or all-female ensemble. It is usually primarily homophonic, with the highest part carrying the melody and the other voices supplying the accompanying harmonies, rather than contrapuntal like a madrigal. Part songs are intended to be sung unaccompanied unless an instrumental accompaniment is specified.
