Musical composition reproduction method and device, and method for detecting a representative motif section in musical composition data

摘要

There is provided a musical composition reproduction device capable of easily reproducing a musical composition structure characteristic section by using a musical acoustic data reproduction device and an interface. The interface (13) has a function to select an arbitrary musical composition structure characteristic section from a plurality of musical composition structure characteristic sections and a function to visualize the musical composition structure characteristic section. Musical composition structure characteristic section specification data specifying the arbitrary musical composition structure characteristic section selected by the interface (13) is given to the musical acoustic data reproduction device (3). The musical acoustic data reproduction device (3) modifies the reproduction position to the musical composition structure characteristic section specified by the musical composition structure characteristic section specification data given by specification data giving means (12).
