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.
