Ž<P>SOLUTION: The predetermined number of musical piece IDs to be practiced to which a singing score value is attached for each singing section based on a user ID is registered in a user classified practice musical piece DB. A performance sound volume determination means 51 compares the singing score value for each singing section of the musical piece ID with a predetermined threshold. It is determined whether it is the threshold or larger, or it is smaller than the threshold for each singing section, and a user classified sound volume management table 58 is created. When a musical piece of the musical piece ID to be practiced is performed, a performance sound volume control means 52 makes performance silence in a singing section of the threshold or larger, and makes performance a predetermined sound volume in a singing section of smaller than the threshold based on the user classified sound volume management table 58.
