ABSTRACT:
A piano type music instrument having playable keys provided in the front of the box, with a sound maker connecting to the keys to make a sound corresponding to the key pressed. A music scale is printed on the box, and in the scale holes are located in the positions corresponding to the music scale notes. A rod inserted in each hole is supported by a link or a pliable tongue member made of thin metal, hard paper of plastic material. The tail ends of the keys are located beneath the pliable tongue or the rod so as to push up and down on the rods smoothly. When a key is pressed down, a corresponding note rod is made to protrude up through a corresponding hole in the printed musical scale, to identify the musical note played and sounded.
