Standard (EADGBE)
So most of the time you're just basically playing a big fat power chord,
with a doubled root note. Accent the D and G# chords by raking on the open
top two or three strings, right before "3" beat. (This is approximately a
sixteenth-note triplet before the actual "3" beat. Listen to the recording
for this, though, it's too beautifully subtle to properly notate.)
For the chorus part, use this 4-chord ascending progression:
(This will
mean playing the bottom strings open, then on the third, seventh, and
eighth frets.)
The rhythm stabs right after the choruses are played on the D chord. Add
the open top strings here again.
