ABSTRACT:
A keyboard musical instrument is fabricated on the basis of an upright piano, and an electronic sound generating system is incorporated therein so as to selectively generate an acoustic piano sound and an electronic sound; a plurality of leaf spring members are provided for the keys of the acoustic piano for imparting a key touch like an electronic keyboard, and a change-over mechanism selectively engages key action mechanisms with the keys and the leaf spring members with the keys so that a player can select the piano key touch or the other key touch like the electronic keyboard depending upon the sound for a performance.
