Tau / A song about a circle constant, written and sung by Victoria "Vi" Hart - http://vihart.com/

Capo on 5th fret

song uses variations of normal chords, as I have a limited "chord vocabulary" they 
will be listed as numbers above the song.

chord "1" - 202220 - use thumb
chord "2" - 222100 - use thumb
chord "3" - 422100 - awkward, but that is what is played
chord "4" - 022102
chord "5" - 202100 - use thumb

they're not perfect, but that's as close as I could get them with my fingers

- verse 1

           E                                    B
when you want to make a circle, how is it done?

         A                              E
Well you probably will start, with the radius 1

        E                                            B
Use a compass or a string, use a paper or the ground

             A                            B
and if the radius is 1, how far did you go around?


- Chorus 1


      A                 1      A
It's Tau! six point two eight, yeah!

      E   1             E     1     E   A
it's Tau, six point two eight three one eight

E    2     3  4      E   B                    E
five three oh seven, one seven nine five eight


- Verse 2


       E                                                   4      
If you pick a certain distance, and you pick a certain spot

        A                          E 
and you put the two together, then what have you got?

           E                                               4
it makes a very special shape, and now you are the inventor,

       A                                                
if you pick all of the points a certain distance from your center,

        4           E                  A
and you got a great collection, and it is a great invention,

       E              4              E
and it makes a lovely circle, well depending on dimension,

            E    E    E
that makes, one, two, three

            E
and there's four and even more.

          4 
but for a circle, and other circles, if you take the distance and compare.


- Chorus 2


      A                 1      A
It's Tau! six point two eight, yeah!

      E   1             E      1     E   A
it's Tau, six point two eight, three one eight

E    2     3  4      E   B                  E
five three oh seven, one seven-nine-five-eight

A        B      A        B            A
six four seven, six nine two five two eight.


- Verse 3


  E                                                     B
I know what you are thinking, what about that other guy?

               A
the one that's sometimes pronounced "pee".

         E
and it's sometimes pronounced "pie"

            E                                       4             B
I mean it's fine when you are building, but it does not belong in math

        A
all the equations make more sense when you use taw or you use taff

              4           E           A            E
and while you get the same answer, no matter which way.

         E               4             E
you get further from the truth when we obscure what we say

              E    E     E
and know it now makes sense.

          E
when it's beautiful and pure

                4
but please don't make it ugly with your bad notation and awful curriculum.
