Moving music

Sonar from Renaud Hallée on Vimeo.

So, this video by animator Renaud Hallée isn't quite a pure infographic—but as you'll see, it's pretty damn close. Titled Sonar, the short film basically visualizes the sound track.

Clavilux 2000 - Interactive instrument for generative music visualization from Jonas Heuer on Vimeo.

What you'll notice in that video is that every note played appears as a stripe of color. Length and vertical position show the force of impact, while width shows how long the note played; the colors correspond to various tonalities. (Discordant notes are marked in contrasting colors.) Thus, the more tonal variations a piece has, the more colors will show up. When a piece is over, the visualization remains, as a visual summary of the music that was just played—what notes were played most, which were loudest, and what harmonies the piece revolved around.
