Claim Text:
1. A musical performance device comprising: a guide section which guides a user by indicating at least a timing of a musical performance operation to be performed next, based on musical performance data representing a musical piece, and waits until the musical performance operation is performed by the user in response to the guiding even after the timing of the musical performance operation is reached; a normal replay section which performs normal audio replay of musical-piece waveform data prepared in advance as accompaniment sound in synchronization with musical sound generated in response to the musical performance operation guided by the guide section; a loop period obtaining section which obtains a loop period corresponding to a beat of the musical piece from the musical performance data; a loop point setting section which sets a loop start point and a loop end point in the musical-piece waveform data in accordance with the loop period obtained by the loop period obtaining section in a case in which the musical performance operation is not performed by the user in response to the guiding when the timing of the musical performance operation is reached; a loop replay section which stops the normal audio replay of the musical-piece waveform data by the normal replay section, and which performs loop replay of the musical-piece waveform data from the loop start point to the loop end point of the musical-piece waveform data set by the loop point setting section; and a replay controlling section which (i) controls the loop replay section to stop the loop replay of the musical-piece waveform data, and (ii) controls the normal replay section to restart the normal audio replay of the musical-piece waveform data from a point at which the loop replay section stopped the normal audio replay of the musical-piece waveform data by the normal replay section, in a case in which, while performing the loop replay of the musical-piece waveform data, the musical performance operation is performed by the user in response to the guiding.
