So I'm a geek, and love math, and so have always stumbled across this kind of songs. I've already posted a Song from π , here's a reply with π's nemesis : τ¹.

1 : π is the ratio between a circle's circumference and it's diameter, roughly 3.14159. τ (pronounced tau) is the ratio between the circumference and the radius, so it's two times π, that is 6.28318.

Okay a little bit geeky, nonetheless, I'll just share this one as I always loved genetic algorithms, and the rules around counterpoint are just fascinating. And for the devs watching this, here's a link to Nicholas' project on Github.

A class I listened to about math and music. Here's the first video of the series.

I've already talked about Animusic here, but discovered recently (thanks to my brother) this project made by Intel to bring Pipe Dream to life.

Matt Mullholand does a lot of a cappella covers (as well as original songs), and I can't post all of them here. So I'll just post a scene from one of my favorite movies, all sounds done by mouth and a single guy.
