    Abstract: A musical rhythm is expressed by the number of the timing marks (for example, three timing marks when in simple triple time); and a musical tempo is expressed by the distance among the timing marks and a timing ball that moves at a fixed speed among those timing marks. Accordingly, a player may easily grasp the tempo of the music and easily determine the rhythm of the music in a sound game.
