Sousaphone

The sousaphone is a brass instrument in the same family as the more widely known Tuba. Unlike the tuba, the instrument is bent in a circle to fit around the body of the musician; it ends in a large flaring bell that is pointed forward, projecting the sound ahead of the player. Because of the ease of carrying and the direction of sound. It is widely employed in marching bands. Sousaphones were originally made out of brass but in the mid-20th century they started to be made from lighter materials like fiberglass.
