An
organ trio, in a
jazz context, is a group of three jazz musicians, typically consisting of a
Hammond organ player, a
drummer, and either a
jazz guitarist or a
saxophone player. In some cases the
saxophonist will join a trio which consists of an organist, guitarist, and drummer, making it a
quartet. Organ trios were a popular type of jazz ensemble for club and bar settings in the 1950s and 1960s, performing a
blues-based style of jazz that incorporated elements of
R&B. The organ trio format was characterized by long improvised solos and an exploration of different musical "moods".
