PROBLEM TO BE SOLVED: To reduce a burden of designating a musical piece to be evaluated when evaluating a musical performance of a user.SOLUTION: A similarity analysis part 22 calculates a similarity index value Z[n] for each of multiple reference musical pieces, according to a degree of similarity between a designated note sequence SQ designated by a user and a reference note sequence SR of the reference musical piece. A musical piece selection part 24 selects the reference musical piece according to the similarity index value Z[n] calculated by the similarity analysis part 22. An evaluation processing part 26 identifies an evaluation index value P for the reference musical piece selected by the music piece selection part 24, according to the similarity index value Z[n] calculated by the similarity analysis part 22. A display control part 28 allows a display device 16 to display an evaluation transition image that shows a time sequence of the evaluation index value P corresponding to each specific note sequence SQ. |
