This category focuses on the saxophone, a woodwind instrument with a typically curved metal body, a flared bell, and a system of keys. Despite its brass construction, it produces sound when a single reed vibrates against the mouthpiece; the keys open and close tone holes to change pitch. Saxophones are known for a broad expressive range, from mellow, rounded tones to brighter, more forceful sounds. The instrument family includes soprano, alto, tenor, and baritone saxophones, which differ in size, pitch, and musical role.
