Abstract: A degree of difficulty of a musical piece is comprehensively evaluated also in consideration of a viewpoint of expressions and dynamics of the musical piece. A segment evaluator evaluates a degree of segment difficulty. The degree of segment difficulty indicates the degree of difficulty in performance of a segment (for example, a predetermined number of measures) serving as a part of the musical piece. The segment evaluator divides the musical piece into a plurality of segments, and evaluates the degree of segment difficulty for each of the plurality of segments. The degree of segment difficulty is evaluated in accordance with a predetermined algorithm. A musical piece evaluator evaluates a degree of musical piece difficulty. The degree of musical piece difficulty indicates a degree of difficulty in the performance of the entire musical piece. The musical piece evaluator evaluates the degree of musical piece difficulty of the musical piece based on a change of the degree of segment difficulty within the musical piece.

Abstract: A musical-performance analysis device includes: an acquisition section that acquires performance information of a player; a determination section that determines, by comparing the performance information acquired by the acquisition section with reference information indicating a reference of a performance, among performance segments different from one another, a performance segment in which a difference degree between the performance information acquired by the acquisition section and the reference information is large and a performance segment in which the difference degree between the performance information acquired by the acquisition section and the reference information is small; and the specification section that specifies a tendency of the performance on the basis of the difference degree of the performance segment in which the difference degree has been determined to be small by the determination section.
