Alright, I think I found the most accurate guitar part for this. Either way, you can
still play it, I just like
this one better, and it's how they've played it before so... This is Avey Tare's guitar
part for the song
"Grass" on the 2005's album "Feels". Enjoy.

REMEMBER, THE TUNING IS A "SPECIAL" OPEN E, NOT STANDARD. (: (Low to High) E, G#, E, G#, 
B, E.

*I'm not doing the intro, only because you can create it however.*

Verses
e|(6)-------------|
B|(6)-------------|
G|-6------(6)-----|
D|-6-------5------|
A|-6-------6------|
E|-6-------5------|

   A# x12  Dm x12

Pre-Chorus(?)
e|(5)----------------|(1)
B|(5)-----14---------|(1)
G|-5------13-------1-|
D|-5------12-------1-|
A|-5---------------1-|
E|-5---------------1-|

   A x10  ??       F x10

(This part, most people will argue about. The synthing does, without a doubt, go A, G,
F, G. Play however!)
(BUT, it also goes A, A#, F... Straight to the chorus. "?" chord is what they'd do live.
Shredding kinda..)

Chorus (Post?)
e|(6)-------|
B|(6)-------|
G|-6--------|
D|-6--------|
A|-6--------|
E|-6--------|

(This is the "Pow/Now" part, which is one chord, disregarding synths. It's played each scream.)

Those are really the only chords to the song, so... Hopefully this was good for anyone.
I'll update it soon.
