Intro: This is played with some delay effect. I tabbed it out as best I could.
Listen to song for exact timing. This is the low part, the very beginning, of
the intro.

E|------------------------------------------------|
B|------------------------------------------------|
G|------------------------------------------------|
D|------------------------------------------------|
A|-----6-5----------------------------------------|
E|-5~~-----5~--3-1--6~~--5~--5h6~--6~--3~--1~--5~-|
  
This is the high pitched part. Again, listen to song for exact timing.
E|-8------8-----------6~-----6~-----8------8------|
B|---8------8-------------------------8------8----|
G|-----8~-----8~---7-8----7-8----7h8----8~-----8~-|
D|------------------------------------------------|
A|------------------------------------------------|
E|------------------------------------------------|

E|-----6~--6-------------------3~-------------|
B|-----------8~---6-4-3-1~--1~----------------|
G|-7-8-----------------------------3-----4----|
D|-----------------------------------5~----5~-|
A|--------------------------------------------|
E|--------------------------------------------|

This is another way of playing the high pitched part. It’s just an octave higher. Both ways sound good.
