This exceedingly clever animation by artist Alan Warburton transforms two compositions from J.S. Bach’s The Well Tempered Clavier (Prelude and Fugue in C Major) into a visual interpretation of music. Warburton used a form of graphical notation manifested as thousands of fluorescent light bulbs mounted around a gallery space and parking garage. As each light pops on in sync with the music, the bulb shape correlates with with length and pitch of each note.

You can learn more about how Warburton and a team of programmers and sound designers created the piece over on Sinfini Music who commissioned the piece. Music performed by Pierre-Laurent Aimard.
