the song is in standard tuning, so E A D G B e

Intro:
e-5-5-5-5-5--5-5-5-5-5--5-5-5-5-5-5-5-|
B-5-5-5-5-5--5-5-5-5-5--5-5-5-5-5-5-5-|

Directly after that comes a part that we shall title Riff 1. just play this riff 
directly after the intro and each time Glenn finishes a sentence. this is also the riff that is 
played during the solo
Riff 1:

E-5-x-x-5-3-|

after the last sentence Glenn sings (which I believe is the 8th) another riff kicks in. 
the timing on this one is a bit tricky, so listen to the track carefully and figure it 
out for yourself!

Riff 2:
e-5-5-5-5-5-5--0-0--1-1-|
B-5-5-5-5-5-5--3-3--1-1-|

D-7-7-7-7-7-7--0-0--3-3-|
A--------------0-0--3-3-|
E-----------------------|  repeat 4 times

directly after that another riff kicks in. it goes like this
Riff 3:
e-----------------|
B-----------------|
G-----------------|
D-----------------|
A---3-------3-----|
E-5---5-3-5---5-2-| repeat 4 times

directly after that, the intro riff is repeated, except 2 times instead of 4.

after that the intro is repeated 4 times, and after that the solo kicks in in which you 
basically play riff 1 8 times.

thereafter comes a breakdown part, wich I haven't quite figured out yet.what I do know 
is that the chords that are played are Am, Dm, F.

then riff 2 is repeated 4 times, riff 3 is repeated 4 times and after that the intro is 
played again 4 times
