Simon Russell Makes Music from Geometry in Houdini

This is based on our solar system. The relative size and rotation and day length etc are all based on real values. Relatively at least ๐Ÿ™‚
Each planet has a pitch based on itโ€™s size. This wave is multiplied by a frequency based on the day length of each planet (it’s rotation).
Volume and stereo panning is based on the planets postiion relative to the camera.

In some of these renders I increased the speed of the system to see what would happen.
Given some time and tweaking I think this system could make some really interesting audio visuals. It’s fun to build and just see what comes out.

The initial idea is Pythagoras’. https://en.wikipedia.org/wiki/Musica_universalis
