<P>PROBLEM TO BE SOLVED: To provide a concert system that can display the deviation from a guide and enables even a person who is unfamiliar with playing a musical instrument to easily obtain the deviation. <P>SOLUTION: A round mark corresponding to a Facilitator is displayed fixedly on a center line among longitudinal lines. A round mark corresponding to each user (e.g. Piano1) moves to the right and the left according to deviation from the Facilitator. For example, when keying is delayed by one bar (four beats in this example) behind the Facilitator, the round mark moves to the left by one longitudinal line. When the keying is delayed by a half bar (two beats), the round mark moves to the left from the longitudinal center line by a half of a line interval. When the keying is earlier than the Facilitator, on the other hand, the round mark moves to the right. <P>COPYRIGHT: (C)2007,JPO&INPIT |
