Now this is fascinating:
Two musicians of the band "After the burial" created a formula to set the decimals of pi to music. Read the description, where they explain how it was done.
In the video you will first hear a guitar intro for about 1 minute, starting roughly at 1:07 you will hear the first 110 (!!) decimal points of pi.
I admit, if you were never involved much in music, it might be difficult to hear the structure, but every musician will be fascinated by a never repeating sound pattern with its very own feel and rythmic evolution.
