An automatic musical instrument includes a tine, a rotor, an actuatable arm, and a rotatable cam. The tine emits an audible sound when vibrated. The rotor has plural picks extending radially outwardly therefrom, and the actuatable arm is disposed to displace the rotor when the actuator arm is pivoted between a normal position and an actuated position. The rotatable cam has at least one protrusion extending outwardly from a surface thereof, and is disposed to contact a pick on the rotor when the rotor is displaced by the actuatable arm. The contact of the rotating cam with the pick of the rotor further displaces the rotor, causing a pick on the rotor to vibrate the tine, emitting the audible sound.
