ABSTRACT:
A keyboard musical instrument allowing a player to perform using acoustic tones or electronic sounds is provided. The keyboard is movable between various positions, such as between a raised and a lowered position. In an electronic sound mode, the keyboard is lowered so as to increase a gap between hammer assemblies and associated strings. The keyboard is lowered using cams or lifters to pull down the keyboard so as to increase a gap between hammer assemblies and associated strings. In this mode, each hammer assembly rebounds on a stopper when a corresponding key is selected, thereby giving a desirable piano touch.
