<P>PROBLEM TO BE SOLVED: To determine a performance content of a key which is performed next, by reflecting the performance content which is actually performed by user's performance operation etc., when a key is operated and performed based on a performance rule. <P>SOLUTION: An automatic performance piano changes the performance rule by comparing a performance content of the key to be performed according to the performance rule with the performance rule of the key which is actually performed, in a passage performance mode for performing automatic performance according to the performance rule in which the performance content of the key to be performed next is specified with respect to the performance content of the key in the past. Thus, the content of the automatic performance is changed in real time by user's performance operation of the key. Moreover, even when the performance content of the key which is actually performed by automatic performance according to the performance rule is deviated from a target performance content, the performance rule is changed to correct it so as to make the deviation small. <P>COPYRIGHT: (C)2011,JPO&INPIT |
