ABSTRACT:
An injection molded saxophone. A main frame of the saxophone comprises a number of injection molded parts. The injection molded parts are namely a neck, an upper body, a main body, a left bell and bow and a right bell and bow. The injection molded parts are preferably made from a substantially plastic polymer. The neck comprises an octave vent for allowing moisture removal. At least one of the injection molded parts has a number of holes formed therein. A keyworks assembly is couplable to the main frame. The keyworks assembly comprises a number of tone hole cover structures, a number of keys and a number of rods. Each tone hole cover structure comprises a lid shaped for covering its corresponding hole. Each tone hole cover structure has an end ring with an end hole that is shaped and dimensioned to fit with an external profile of one of the number of rods. Operation of the rod varies at least one hole between the open state and the closed state to thereby vary pitch of generated sound.
