Abstract: Not only an image signal of a scene of performance of musical instruments and a sound signal of such performance, but also the performance data of a specific musical instrument are recorded by a video system, and by virtue of a reproduction of this record, the image signal, the sound signal and the performance data are separated from each other. Thus, not only the image from the image signal and the electronically reproduced sound from the sound signal, but also a real automatic playing musical instrument such as player piano corresponding to said specific musical instrument is actually driven to effect a performance, whereby the watcher-listener is also able to listen to the performance sound of a real musical instrument.
