The game's main feature, Jam Mode, features 50 songs that consist of a combination of classical and traditional songs, seven Nintendo songs, and 15 licensed songs.[12][13] Before playing -the selected song, the players each choose any of the available instruments and then perform as one of six different members of a band; the six available sections are melody, harmony, chord, bass, and two percussion parts.[7][14] Unoccupied sections are played by computer-controlled "Tute" characters or can be dropped altogether.
