Using the rhythm action game described in the present invention, a user selects the number of keys that are used to hit note images while playing the game, so that a game mode is determined, and thus the difficulty level of the game can be determined. Further, the present invention notifies the user who is playing the game of the results of note-based games, not only using images, but also using vibrations. Further, the present invention provides sync information for respective types of terminals, thus enabling the play of music to be synchronized with the output of images.
