PURPOSE: To make it possible to previously record evaluation information relating to the music sung by individuals and to display the same.

CONSTITUTION: The musical tones are reproduced from an optical disk by an LD player 105 and a user sings a song by using a microphone 107 in compliance therewith. A score deciding section 106 makes evaluation by collating the input from this microphone 107 and the input from this LD player 105. The score of the result of this evaluation is recorded in an optical card by an optical card information recording and reproducing device 101. The scores recorded relating to this music in the past are read out together therewith and are displayed in the form of a graph or the like. The transition of the scores are, therefore, made easily visible and the degrees of improvement, etc., are easily recognized.
