visual harmony

Here's a link to something called visual harmony. Here's an
explanation.

...playing... with the ideas of experimental film pioneer John Whitney, using both graphics and audio. While Whitney was interested in turning musical ideas into motion graphics, I’m doing the inverse — turning one of his key animation ideas back into music.

In the movie above,

each of the 48 dots is moving in a circle. Each of the dots is on a 3 minute cycle. At the end of 3 minutes, the outermost dot will have moved around the circle once (this dot represents the first harmonic or fundamental). The next dot will have moved around the circle twice (representing the second harmonic). The next dot three times, and so on. The innermost dot moves around the circle 48 times.

Now, imagine these dots are raised bumps on a disc which is controlling a music box, with each bump triggering a note when it passes the zero degree line (a line extending from the center to the east).

That sounds complicated... check out the explanation for more details for you tech types. Otherwise enjoy the images and music... it's kind of neat.
