PROBLEM TO BE SOLVED: To display a mark showing an analysis result of singing in association with a graph of a singing result in a visually comprehensive mode by a display system when a performance speed of the karaoke musical piece becomes faster due to a speed control function.SOLUTION: A graph display area for scroll-displaying a graph showing a reference pitch of musical piece and a graph showing a singing result in a horizontal axis (axis X) direction according to performance of the musical piece, and a mark display area for scroll-showing a technique mark showing an analysis result of singing voice in the horizontal axis (X axis) direction according to a progress of the performance of the musical piece are provided in different individual areas. When a performance speed of the musical piece is increased more than a reference value, the progress speed that makes the graph in the graph display area scroll is made to increase according to an increase of the performance speed. In the meantime, the progress speed of the technique mark in the mark display area is adjusted to the progress speed relatively slower than the progress speed of the graph in the graph display area and thereby to make the technique mark scroll. |
