A keyboard-type percussion instrument having sounding members arranged to correspond to respective ones of keys and capable of improving musical performance in soft tone. When a soft pedal is stepped on, a pedal connecting rod is moved upward to move an arm portion of a lifting arm upward, whereby the lifting arm is pivoted to cause capstan screws to be inserted into through holes of a key frame, thus moving a lifting bar upward so that an upper surface of the lifting bar projects from the key frame to push rear end portions of all the keys upward. As a result, standby positions of hammer felts are moved toward the sounding members, whereby the volume of a tone generated by a sounding member struck by a hammer felt corresponding to a depressed key is decreased.
