The baritone saxophone or "bari sax" (commonly abbreviated bs or bars to distinguish it from the less frequently used bass saxophone) is one of the largest members of the saxophone family, only being smaller than the bass, contrabass and subcontrabass saxophones. It is the lowest-pitched saxophone in common use, and uses a mouthpiece, reed, and ligature that are larger than the tenor, alto, and soprano saxophones, the other commonly found members of the family.
