In a musical instrument, such as a piano, having a sound board (7), the sound board vibrates in response to vibrations of a string (5) responsive to depression of a key (2). A waveform corresponding to such vibrations of the sound board is detected and recorded. The recorded vibration waveform is usable for reproduction of a sound based on sound board vibrations. In a sound reproduction apparatus, such as a piano, having a sound board, an excitation device (50) physically excitable in response to an input waveform is provided on the sound board. A signal indicative of a vibration waveform of the sound board is received, and the excitation device (50) is driven in accordance with the received waveform signal so that the sound board is vibrated. Thus, a sound based on the sound board vibrations can be replicated or reproduced with a high quality. |
