Translated into guitar.

Basically,

INTRO

E|----------------------------------------|
B|--3-3-3-3-------------------------------| repeat until >
G|--3-3-3-3-------------------------------|
D|----------------------------------------|
A|----------------------------------------|
E|----------------------------------------|

Throughout the rest of the song it's a combination of:

E|----------------------------------------|
B|--3---3---3-----------------------------| [repeat]
G|--3---0---2-----------------------------|
D|----------------------------------------|
A|----------------------------------------|
E|----------------------------------------|

- usually in that order, but I believe it may vary, slightly, once or twice. The only 
you'll learn how many times the notes are struck, is to listen, and play along.
