Abstract
In the present invention, a CPU identifies musical notation data to which music playing data corresponds, and determines whether the musical notation data has been played using a right-hand, a left-hand, or both hands. When the pitch of the identified musical notation data and the pitch of the music playing data match, the CPU sets a clear flag in the identified musical notation data to “1” to indicate that the note has been correctly played. Then, the CPU extracts the number of occurrences and the number of times cleared for each musical performance technique type, and acquires an achievement level based on the difficulty level of the song by accumulating achievement levels for each musical performance technique type which are calculated based on their accuracy rates acquired from the extracted number of occurrences and number of times cleared and difficulty levels according to their types.
