Meanwhile, when the sound volume is set while the predetermined music piece is being outputted in a low-recognition state in which a recognition performance of the predetermined music piece is lower than that in the predetermined state (for example, a second fade-out period), a specific notification sound is outputted with the sound volume corresponding to the set stage. As a result, notification is performed by the specific notification sound when the predetermined music piece is outputted in the low-recognition state, thus permitting adjustment to sound volume intended by the player.SELECTED DRAWING: Figure 6
