An automatic playing apparatus which reads tone information from a ROM piece by piece to play a demonstration. The tone information stored in the ROM includes note data for generation of a musical tone as well as data for changing the parameters of music corresponding to the note data. When a demonstration is played, the note data and the data for changing the music parameters stored in the ROM are read out piece by piece, and the associated musical tones are generated accordingly. In this way, the musical piece being automatically played changes with each repetition, so that listeners hear a different version of the piece each time it is re-played.
