The baritone saxophone (sometimes abbreviated to "bari sax") is a member of the saxophone family of instruments, larger (and lower-pitched) than the tenor saxophone, but smaller (and higher-pitched) than the bass. It is the lowest-pitched saxophone in common use — the bass, contrabass and subcontrabass saxophones are relatively uncommon. Like all saxophones, it is a single-reed instrument. It is commonly used in concert bands, chamber music, military bands, big bands, and jazz combos. It can also be found in other ensembles such as rock bands and marching bands. Modern baritone saxophones are pitched in E♭.
