PROBLEM TO BE SOLVED: To display a reference graph serving as a singing model switched for each performance section so as to allow a singer to easily recognize the reference graph immediately after switched.SOLUTION: A reference graph indicating a reference melody for each predetermined performance section corresponding to a progress position of a performance is displayed in a main monitor region, and a progress line indicating the singing position corresponding to the progress position of the performance is moved and displayed in association with the reference graph in the main monitor region, according to a progress of the performance. When the progress position of the performance reaches a predetermined position of the performance section corresponding to the reference graph, an advance graph corresponding to a portion to a partial section from a top of a reference graph corresponding to a subsequent performance section to be displayed in the main monitor region is displayed in a sub-monitor region. When the progress position of the performance reaches an end of the performance section corresponding to the reference graph, display in the main monitor region is switched to the reference graph corresponding to the subsequent performance section.SELECTED DRAWING: Figure 2 |
