PURPOSE: To easily and surely recognize a discrimination result by providing plural sound emission means as a discrimination result report means and controlling plural sound emission means so that the occurrence position or the feeling of spread of musical sounds may be different between correct operation and erroneous operation. CONSTITUTION: Each time performance information occurs from a performance information generation means, a discrimination means compares this information with performance operation information from a performance operation means to discriminate whether the performance operation is correct or not. A control means controls plural sound emission means so that the occurrence position or the feeling of spread of musical sounds may be different between correct operation and erroneous operation, and for example, a sound system is switched to make the occurrence position of musical sounds different between them or a stereo effect is given or not given to make the feeling of spread of musical sounds different between them. Thus, a trainee is not psychologically pressed and can easily and surely discriminate whether the performance operation is correct or not. |
