<P>PROBLEM TO BE SOLVED: To provide a clue to higher matching in playing in concert. <P>SOLUTION: A plurality of kinds of playing parameters of rhythm, dynamics, etc., of a plurality of playing terminals are acquired based upon reception timing and velocity information of note-on messages input from the respective playing terminals to detect deviations of a facilitator etc., from reference values. On a two-dimensional plane representing two kinds of playing parameters on its axes, traces of deviations of playing parameters of the respective playing terminals are displayed (a). Each player views the display and corrects his or her musical performance to increase matching in playing in concert. Further, deviation quantities can be displayed by deforming a two-dimensional figure such as a diamond shape according to the deviation quantities (b). Furthermore, the deviation quantities can be displayed by changing positions of components of a face according to the deviation quantities (c). <P>COPYRIGHT: (C)2008,JPO&INPIT |
