## Pi Music

While we’re on the subject of $\pi$, take a look at this link. There’s not much actual math behind it, but it’s just kind of fun. The idea is that you choose ten notes, one for each of the digits 0-9, and then it plays the first 10,000 digits of pi using the notes you chose. In other words, it makes the digits of $\pi$ into a song! It’s not particularly useful. But who cares?
