Abstract
A score display apparatus shows beat marks in a number corresponding to the number of beats per measure during a performance by a musical instrument karaoke apparatus. Further, the score display apparatus changes the color of each of beat marks as though the beat mark is wiped with a different color in a predetermined direction in synchronism with the tempo of a performance of the musical instrument karaoke apparatus, and changes the color of the displayed beat marks in synchronism with the timing of the beats.
