<P>PROBLEM TO BE SOLVED: To provide a technique of expressing the accuracy of singing voice pitch with lights by an illumination system beautifully, gorgeously and pleasantly rather than clearly. <P>SOLUTION: A microcomputer 21 lights a lamp B in a color corresponding to pitch on receiving musical note data A. In this case, luminance is a standard value of about 50% of the maximum luminance. A little after this, pitch accuracy data C corresponding to the musical note data A is received. If the pitch accuracy data C falls within a standard range, the microcomputer 21 holds the luminance of the lamp B. If the pitch accuracy data C is worse than the standard range (if a pitch error is large), the worse the data C is, the lower the luminance of the lamp B becomes. Conversely, if the pitch accuracy data C is better than the standard range (if the pitch error is small), the better the data C is, the higher the luminance of the lamp B becomes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
