The Andantephone is a newly invented musical instrument. The player interacts with the instrument by walking along the pads. Each pad is programmed to a particular chord or melody in a song, allowing the player to walk along the sequence to playback the song (walking through the song's timeline). The player dictates the tempo of the song as they speed up and slow down and if the player stops walking the music will stop. The pads are not programmed to play back keys in order, they are programmed to help teach people the basic principles of music, rhythm and tempo, as it transforms walking into a musical act.
