It’s once again the day to celebrate π. Last year I gave you a little artist’s book (and a recipe for cabbage pie) to make for yourself. This year I found a suitable piece of music on Will Wheaton’s Tumblr.
If you play the ukulele, you could try it out. Otherwise you can hear this version (and another arranged with chords) by visiting here.
(In case you have never seen musical notation that looks like this, there’s an explanation of tablature here.)
