Abstract

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 into a memory for each of the keys. 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 physically excitable in response to an input waveform is provided on the sound board. In response to an operation of a key, a sound board vibration waveform corresponding to the operated key is read out from the memory, and the excitation device is driven in accordance with the read-out waveform signal so that the sound board is vibrated. Thus, a sound based on the sound board vibrations can be replicated or reproduced in response to the operation of the key with a high quality.
