Abstract
A keyboard musical instrument comprises a plurality of juxtaposed movable key units and a plurality of juxtaposed strings, each of which has one end fixed to the corresponding key unit and the other end immovably attached to the body of the key board musical instrument and is vibrated at a prescribed frequency upon operation of the corresponding key unit, wherein each string is prevented from making vibration by a stationary damping member while the corresponding key unit remains inoperative and commences vibrations at a prescribed frequency upon operation of the key unit; and the vibrations are electrically detected by pickup devices and, after amplified, are sent forth through a loud-speaker as a musical tone.
