The Fife Companion is a musical role traditionally filled by a drummer. The drummer plays a small, high-pitched flute-like instrument called a fife, which is used to accompany marching bands and other military-style music. The drummer is responsible for keeping the beat and providing a steady rhythm for the rest of the band. The Fife Companion is an important part of any marching band or military-style ensemble, as they provide the backbone of the music.
