1. A scoring apparatus for evaluating a live vocal performance which is voiced by a singer along with a karaoke music synthetically reproduced from melody data, the scoring apparatus comprising:

  • a first detector that sequentially detects the live vocal performance to extract therefrom sample data which is characteristic of actual voicing of the singer;

    a second detector that sequentially detects the melody data to extract therefrom time data representative of model progression of the karaoke music and reference data representative of model voicing which should match the karaoke music;

    a comparator that sequentially compares the sample data and the reference data with each other to produce differential data which indicates difference between the actual voicing and the model voicing; and

    a processor that processes the differential data with reference to the time data to produce score data which represents degree of deviation of the live vocal performance voiced by the singer relative to the karaoke music, wherein the score data includes a MIDI message containing note-on or note-off status.
