By controlling the light emission mode, the playing method is further displayed. Therefore, the performance method of pushing up the string held down, for example, by choking, is displayed according to the light emission form of the light emission display portion.

Further, in the invention described in claim 4, the light-emitting display body is constituted by an aggregate of light-emitting display portions having the same size and being miniaturized. Therefore, the control means controls the light-emitting display state of these light-emitting display portions, so that the position at which the performance operation is to be performed is displayed precisely.

According to a fifth aspect of the present invention, the control means is configured to control each of the light emitting display portions to further display display information such as characters and figures. Therefore, it is possible to not only indicate the position at which the performance should be performed, but also to display characters and graphics in a predetermined area of the musical instrument, thereby forming a performance form that can stimulate not only an auditory stimulus but also a visual stimulus. It becomes possible.

Further, in the invention according to claim 6, since the display illuminant is an electroluminescent panel driven in a matrix system, it can display characters and figures without complicated control. I can make it.
