For example, the part of karaoke music corresponding to the type of instrument determined in S102 may be automatically determined as the specific part. In addition, at least one part of the guide melody or the guide vocal may be automatically determined as the specific part. Further, the part of the karaoke music corresponding to the type of instrument determined in S102 and at least one part of the guide melody or the guide vocal may be automatically determined as the specific part.

  In the next S110, the control unit 11 sets the volume value of each part in the internal music data to be played so that the volume of the specific part determined in S108 is relatively higher than the volume of the other parts. . Specifically, it is conceivable to set the volume value of the determined specific part larger than a prescribed volume value during normal playback or a volume value set in the karaoke apparatus 10. Alternatively, the volume value of a part other than the determined specific part may be set to be smaller (including mute) than a prescribed volume value during normal playback.

  On the other hand, in S112, which proceeds when it is determined in S100 that the instrument practice mode is not to be executed, the karaoke piece to be played is determined based on the received request information. In S <b> 114, the control unit 11 sets the volume value of each part in the internal music data to be played back to a default volume value during normal playback or a volume value set in the karaoke apparatus 10.

  In S <b> 116, the control unit 11 causes the music playback unit 13 to play back the music composition data of each part included in the internal music data to be played. At this time, the control part 11 outputs the reproduction sound of each part from the speaker 21 according to the volume value set in S110 or S114. In parallel with the internal music data playback process, the input sound input from the microphone 19 or the musical instrument 20 is output from the speaker 21. When the reproduction process of the internal music data ends, the control unit 11 ends this process.
