where does the reed go on a saxophone
Reed (mouthpiece) Single reeds are used on the mouthpieces of clarinets and saxophones. The back of the reed is flat and is placed against the mouthpiece, the rounded top side tapers to a thin tip. These reeds are roughly rectangular in shape except for the thin vibrating tip, which is curved to match the curve of the mouthpiece tip. All single reeds are shaped similarly but vary in size to fit each instrument's mouthpiece.
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.
