A saxophone is a woodwind instrument, despite being made of brass. Invented by Adolphe Sax in the 1840s, it combines features of both brass and woodwind instruments. The saxophone has a single-reed mouthpiece similar to that of a clarinet, which produces sound when the player blows into it. It comes in various sizes, including soprano, alto, tenor, and baritone, and is widely used in jazz, classical, and popular music. Its expressive tone and versatility have made it a favorite among musicians across different genres.
