The music of Pi

I thought it was interesting to discover that there alot of music done using Pi. Obvious really, but its a very interesting debate about copyright when the piece is based on a number created by nature. I suppose there is some artistic creation going on at the point when the notes are ascribed to numbers. In this video he goes C0 1 D = 2, well one would get a different result if you made C=1 and Dflat = 2

And heres a video about the controversy: She explains the translation as a regular adopted scale.

Im going to learn these notes
