Abstract
A grand piano is equipped with a sound controller for controlling qualities of a sound to be produced in a sound board and top boards of the grand piano, and the sound controller comprises a parameter switches for providing parameters indicative of qualities of a modified sound, sensors for detecting the qualities of the sound originally produced in the boards, a data processor responsive to the parameters for producing an actuating signal, and actuators associated with the boards for producing additional vibrations therein, wherein the additional vibrations are overlapped with the vibrations originally produced so that composite vibrations with the qualities indicated by the parameters take place in the boards, thereby controlling the acoustic sounds.
