Intro:

A simple riff on the E string...

e | ---2b-(pause)-2-3-5-6-5-3---- |  (repeat from the beginning about 5-6 times)
B | ----------------------------- | 
G | ----------------------------- | 
D | ----------------------------- | 
A | ----------------------------- | 
E | ----------------------------- | 

The second guitar plays D5 / Bb5 under this.

Verse:

D5           A5
 Am I still alive?
                     B5 
 I think I've got it right...
A5
 I'm made of light..
D5                   A5 
 Before I leave and go away,
                     C5
 There's some things I must say,
   B5 
 Before - before I'm gone...

On "gone", turn on distortion and play A5 / C5 twice.

This same progression repeats for the next verse.

Pre-chorus:
A5   C5  A5                C5
         There's so many possibilities -
A5   C5  A5                       G5
         And I'm just starting to see...

Now go directly to the Chorus:
G5  A5   Bb5       A5                 G5
         It's like the poets always said
    A5   Bb5          A5                 G5
         When life is hanging from a thread
    A5   Bb5               C5            D5
         You can hear that voice in your head....

And now return to the
D5 / Bb5 
sequence from the intro.

The interlude is just a three-note riff on the E string:

e | ----2-3-2-3-2-2-0--- | 
B | -------------------- | 
G | -------------------- | 
D | -------------------- | 
A | -------------------- | 
E | -------------------- | 

For the rest of the song, use the pre-chorus and chorus chords.

The coda is D5 / Bb5. End on D.

Don't be afraid,
G.
