The official "birthplace" of Pi Day is San Francisco Exploratorium, now there is even webpage Pi Day.

NPR explains how to transform number Pi into song.

Mathematics and music are connected not only through the Pi.
Some time ago pianist Stephen Hough visited Ithaca and it was a wonderful performance. I treasure his CD "Complete Chopin Waltzes".  I was surprised to learn that he is also interested in connections between mathematics and music.

I noticed this TED talk on gizmodo.com because of the title, of course -
only a mathematician could love the world's uggliest music..

Another resource for Music and Math - The Maths of Music

On YouTube there is a quite a number of "Math songs" - for example
Algebra and Calculus or Getting Triggy with it - math rap song.

Happy Pi Day!
