Happy pi day! That is, today is March 14th, or 3/14. In celebration of the well-known irrational number, musician Michael John Blake decided to compose a musical interpretation of the figure. First, he composed the piece in C, and then assigned each not a number, beginning with C as #1, D as #2 and so forth. In the end, the composition plays through the sequence up to 31 decimal places. (3.14159... you get the picture). Numbers have been assigned to chords as well and he also claims to have used pi as inspiration for the tempo, which is at 157bpm, or half of 314.
I hear he's put a video of his performance up on Utube, if you care to see it. Several instruments are involved.
