To easily retrieve desired movement data.
A feature presentation information generation part 72 generates feature presentation information for presenting the feature of the movement of a music robot apparatus 12 based on the movement data by displaying the feature. A control part 70 stores the feature presentation information in a storage part 73 and reads the feature presentation information from the storage part 73 according to a request for presentation of the feature of the movement from outside. Consequently, by displaying and presenting the feature of the movement of the music robot apparatus 12 based on the movement data on the basis of the feature presentation information, the feature of the movement of the music robot apparatus 12 based on the movement data is easily confirmed and the desired movement data are easily retrieved without actually moving the music robot apparatus 12 according to the movement data.
