A
jazz trio is a group of three
jazz musicians, often a piano trio comprising a
pianist, a
double bass player and a
drummer. The pianist is usually considered the leader of these trios, and trios are usually named after their pianist. Famous examples include the
Bill Evans Trio with
Scott LaFaro on bass and
Paul Motian on drums; and the
Vince Guaraldi trio, featuring Fred Marshall and Jerry Granelli.
