Bari Sax

This abbreviation refers to the baritone saxophone, one of the largest members of the saxophone family. It is the lowest-pitched saxophone in common use, and the mouthpiece, reed, and ligature it requires are larger than those of the tenor, alto, and soprano saxophones. The baritone saxophone is commonly used in classical music (such as concert bands, chamber music, and solo repertoire), military bands, marching bands, and jazz (such as big bands, jazz combos, etc.).
