ABSTRACT:
A harmonica with increased musical range and volume is disclosed. The technique used to produce some of the additional notes is called bending. To increase the musical range of the instrument, the harmonica has four reeds per reed cell. Two of the reeds are traditional blow and draw reeds and the other two reeds are enabler reeds for enabling the blow and draw reeds to both be bent to lower frequencies. All four reeds have check valves which are essential for the enabler reeds to preclude unwanted sympathetic vibration in adjacent cells. One embodiment permits a single valve to serve two reeds.
