Fife and drum blues is an American folk music form derived from country blues, martial music tradition, and African rhythms. It is performed typically with one lead fife player and a troop of drummers. Unlike a drum corps, the drum troop is loosely structured. As such, a fife and drum band may have a variable number of snare, tom, and bass drum players. A large military-style bass drum is preferred. Fife and drum performances are often family affairs held at reunions, summer community picnics, and on holidays.
