B flat clarinet

A B-flat clarinet is a common woodwind instrument that sounds a whole step (two semitones) lower than the written pitch. When a player reads a note on sheet music, they must play it a tone higher to produce the correct sound. It features a straight cylindrical tube with a curved bell, mouthpiece, and a system of keys that open and close to produce different notes. The B-flat clarinet is popular for its warm tone and versatility across many musical genres, making it a staple in bands, orchestras, and chamber groups.
