Claim:
A performance guide apparatus comprising: a performance operation section including a plurality of performance operators; a two-dimensional display section provided near said performance operation section; an acquisition section that acquires performance data; and a display control section that, in accordance with the performance data acquired by said acquisition section, controls said two-dimensional display section so as to indicate each of the performance operators to be operated in accordance with a progression of a performance, wherein, in accordance with a passage of time, said display control section causes said two-dimensional display section to display a moving two-dimensional trajectory, from a first display position corresponding to one of the performance operators to be currently operated to a second display position corresponding to another one of the performance operators to be operated next, wherein said display control section controls said two-dimensional display section to display the moving two-dimensional trajectory in a display style variably controlled in accordance with performance-related information pertaining to at least one of the performance operator to be currently operated or the performance operator to be operated next, and wherein the variably-controlled display style variably controls a height of a bounce peak point of the two-dimensional trajectory representative of bouncing movement.
