Abstract
A mouth organ having suction-excited and pressure-excited reeds which cooperate with slotted plates is provided with a pair one-way of valve defining members formed from sheet material. The first valve member defining includes plural integral flaps which respectively act as individual valves to control air flow over associated suction-excited reeds. The second valve defining member is in the form of a single flap which is loosely disposed to move perpendicularly relative to the slotted plate with which the pressure-excited reeds cooperate.
