B|---3----|                                      
G|---2----|                                      
D|---2----| (keep repeating this chord in intro) 
A|--------|                                      
E|--------|                                      

E|--------5----------|

D|----5---7----------| 
A|-------------------| 
E|-------------------| 

Those are the chords involved in the main part.  I think you'll be able
 to hear the rhythm.  The second
is hit twice.

Next part:

E|----------------------| 
B|--2--2-2-3--3-3-(12)--| 
G|--3--3-3-4--4-4-(12)--| 
D|--4--4-4-5--5-5-(12)--| 
A|----------------------| 
E|----------------------| 

The ()s denote harmonics.  They aren't hit every time; you can hear 
them clearly ringing if they're there.
The second time this part is played, the harmonics are on the 5th fret,
 lower three strings once, then
on the 12th fret I think.

Final part:
