This riff is basically the whole song


    Section A                                               Section B                    
                Back to Section A
E-----------------------------------------------------------------------|
B-----------------------------------------------------------------------|
G-----------------------------------------------------------------------|
D----------------------x4------------8-8-9-8--x2------------------------|
A-----------8-8-9-8--------8-8-11-11------------------------------------|
E--8-8-11-11------------------------------------------------------------|

After you go back to section A, then go on the section B, and then back to A. Get the pattern?

Note: Play the notes as mostly even eight notes, but give it a slightly swung feel. Also 
it sounds good with the bridge pickup on, a hight treble, slight gain and lots of 
reverb, but that stuff is up to you.
