PROBLEM TO BE SOLVED: To provide an instrumental sound output device that evaluates synchronized performance by a plurality of kinds of electric instruments in a comprehensive manner.SOLUTION: An instrumental sound output device includes: attack sound extraction means 82 for extracting attack sounds corresponding to performance sounds respectively input from a plurality of kinds of electric instruments on the basis of sound pressure levels of the performance sounds according to a predetermined relationship; and synchronized performance evaluation means 84 for evaluating synchronized performance by the plurality of kinds of electric instruments on the basis of the attack sounds extracted by the attack sound extraction means 82. With this configuration, when players respectively playing the plurality of kinds of instruments form a band, and play the plurality of kinds of instruments in synchronization to play one piece of music, the instrumental sound output device can appropriately evaluate harmony of the entire band performance. |
