Lyrics:

When you want to make a circle, how is it done?
Well, you probably will start with the radius 1
Then use a compass, or a string, and use a paper or the ground
And if the radius is 1, how far did it go around?

It's tau! 6.28
Yeah, it's tau! 6.28

If you pick a certain distance, and you pick a certain spot
And you put the two together, then what have you got?
It makes a very special shape, and now you are the inventor
If you take all of the points a certain distance from your center

And you've got a great collection, and it is a great invention
And it makes a lovely circle, well depending on dimension
Cause there's 1, 2, 3, then there's 4 and even more
But for a circle, how much circle's there if you take the distance and compare?

It's tau! 6.28
Yeah, it's tau! 6.28

I know what you are thinking, what about that other guy?
The one that's sometimes pronounced pee, and sometimes pronounced pie?
I mean it's fine if you are building, but does not belong in math
All the equations make more sense when you use taw, you use taff!

And while you get the same answer no matter which way
We get further from truth when we obscure what we say
You know that math makes sense when it's beautiful and pure
So please don't make it ugly with your bad notation and awful curriculum

Use tau! 6.28
Yeah, use tau! 6.28
