Abstract: In a musical piece reproducing system, a reproduction control unit causes a sound device to reproduce a musical piece. A display control unit causes a display device to display motion graphics based on motion graphic data stored in a storage device. The motion graphic data defines, for each type of a musical piece portion, a corresponding motion graphic that the display device should display when a musical piece portion that belongs to a corresponding type is reproduced. The display control unit determines the type of each of musical piece portions contained in the musical piece to be reproduced, and controls the display device in such a way that when each of the musical piece portions is reproduced, the display device displays a motion graphic defined by the motion graphic data in accordance with the type of the musical piece portion.
