Abstract:
    A grand piano have a keyboard implemented by white and black keys selectively depressed by a player for specifying the notes of tones to be generated, and action units are linked with the white and black keys so as to give rise to free rotation of associated hammers through escape, wherein a key-touch regulator is provided between the key frame and the white and black keys for partially canceling the moment initially exerted on the white and black keys due to the self-weight of the action units and the hammers so that any lead weights is not required for regulating the key-touch.
