Easy nuff. The main riff in the song.

E|---------------------------------------|
B|---------------------------------------|
G|---------------------------------------|
D|---4-X-4-X-4-X-4-X-4-X-4-X-4-X-2-X-7---|
A|---4-X-4-X-4-X-4-X-4-X-4-X-4-X-2-X-7---|
D|---4-X-4-X-4-X-4-X-4-X-4-X-4-X-2-X-7---|

The other main riff that kicks in occasionally. Mute the strings almost like you're 
trying to make harmonics instead of just quiet the strings, it sounds much more like the song.

Also, he's noodling around on the G string or something in the background, too tough to 
make out. Just mess with the 14-13-11-9 frets and such if you feel like it.

E|-----------7---5---|
B|-------5---5---5---|
G|---6---6---6---6---|
D|---7---7---7---7---|
A|---7---7---0-------|
D|---5---------------|

In that little interlude at about 1:20 or so in, he just messes around with a base 
barred A chord, the main variations being tabbed out above. Just mess around with what sounds 
good, these are the main ones though.

Then repeat the first two riffs a few more times, until you get to 2:12 or so. Start 
messing with that barred A in the background again, the lead is something along these lines:

E|-------------------------------------------|
B|-------------------------------------------|
G|-------------14---13-------------14---11---|
D|---11---14-------------11---14-------------|
A|-------------------------------------------|
D|-------------------------------------------|

Do this once, then,

E|-----------------------|
B|---12-------14---------|
G|------14-11----14-11---|
D|-----------------------|
A|-----------------------|
D|-----------------------|

Over and over again, occasionally only performing the first triplet, and if you feel 
like it, mess with the other notes on the scale. After that, it's pretty much more noodling 
with the barred A, and then this lead:

E|--------12/14---|
B|---14-----------|
G|----------------|
D|----------------|
A|----------------|
D|----------------|

Do that several times, and end with going back and forth slowly between the 14th and 
12th fret on the high E.

Then do the first couple riffs again, then smash that barred A chord into oblivion while 
noodling around where I've told you to already...the lead's buried so far down I can't 
get a good idea of what it really is, but it doesn't matter, this is math rock. Have a blast.
