An electronic piano is provided with keyboard operated or controlled tone generators providing electric oscillations corresponding to piano tones. These oscillations are amplified by an amplifier, and are applied to two loudspeakers located at opposite ends of the keyboard. The loudspeaker at the left end of the keyboard is adapted to reproduce the piano bass tones at relatively high efficiency while the loudspeaker at the right end of the keyboard is adapted to reproduce the treble tones at relatively high efficiency, whereby the tones throughout the gamut of the piano are located primarily at the same locations relative to the keyboard as they would be on a mechanical or conventional string piano. A third speaker is provided on the panel below the keyboard to simulate sound emanating from a piano soundboard.
