There is provided a performance apparatus that can reduce energy consumption
while allowing sounding elements to appropriately generate sound. A CPU supplies
driving energy to an actuator to drivingly control the same based on pulse width
modulation. A rotary pick is rotatively driven by the actuator to pluck reeds to
generate sound. The CPU sets the duty of a driving pulse for driving the rotary
pick during time points t3 and t4. Thus, higher driving energy is
supplied to the actuator in timing in which the rotary pick plucks any of the reeds
than in timing in which the rotary pick does not pluck any of the reeds.
