is a saxophone a woodwind or brass instrument
Saxophone The saxophone (also referred to as the sax) is a family of woodwind instruments. Saxophones are usually made of brass and played with a single-reed mouthpiece similar to that of the clarinet.[2] Like the clarinet, saxophones have holes in the instrument which the player closes using a system of key mechanisms. When the player presses a key, a pad either covers a hole or lifts off a hole, lowering or raising the pitch, respectively.
Sousaphone The sousaphone is a valved brass instrument with the same tube length and musical range as other tubas. The sousaphone's shape is such that the bell is above the tubist's head and projecting forward. The valves are situated directly in front of the musician slightly above the waist and all of the weight rests on the left shoulder. The bell is normally detachable from the instrument body to facilitate transportation and storage. Except for the instrument's general shape and appearance, the sousaphone is technically similar to a tuba.
