1. A performance evaluation apparatus comprising:

  • a reference-performance data supplying unit for successively supplying reference-performance data, the reference-performance data prepared for designating a pitch of a musical sound for generating a sound, a time at which a sound of the musical sound should be generated and a time at which the sound of the musical sound should be vanished;

    a actual-performance data supplying unit for successively supplying actual-performance data including a time of instructing to generate a sound of a musical sound at the designated pitch and a time of instructing to vanish the sound of the musical sound;

    a reference on-period extracting unit for extracting a reference on-period indicative of a period between the time at which the sound of the musical sound should be generated and the time at which the sound of the musical sound should be vanished, based on the reference-performance data supplied from the reference-performance data supplying unit;

    a real on-period extracting unit for extracting a real on-period indicative of a period between the time of instructing to generate the sound of the musical sound and the time of instructing to vanish the sound of the musical sound, based on the actual-performance data supplied from the actual-performance data supplying unit;

    a judging unit for judging whether the reference on-period extracted by the reference on-period extracting unit and the real on-period extracted by the real on-period extracting unit overlap with each other or not;

    a comparing unit for compare the pitch of the sound generated in the reference on-period extracted by the reference on-period extracting unit and the pitch of the sound generated in the real on-period extracted by the real on-period extracting unit, only when the judging unit determines that the reference on-period and the real on-period overlap with each other; and

    an evaluation score calculating unit for adding an evaluation point to an evaluation score, when the comparing unit determines that both the pitches are the same and for subtracting the evaluation point from the evaluation score, when the comparing unit determines that both the pitches are not the same.
