These are the chords without a capo.  The key is E major.  The riff is pretty simple and 
are plenty of good tabs on this site with an accurate tab of it so check them out.  
are the chords with lyrics.

Verse 1:
                   C#m (x13321@4)          EIt's (022100@1)empty in the valley of your heart
                   C#m (x13321@4)          EThe (022100@1)sun, it rises slowly as you walk
                   C#m (x13321@4)            E (022100@1)           B (x2444x@1)     EAway (022100@1)from all the fears and all the faults you've left behind

Verse 2 (repeat verse chords):
The harvest left no food for you to eat
You cannibal, you meat-eater, you see
But I have seen the same, I know the shame in your defeat

Chorus 1:
    E (022100@1)     A (x02220@1)     EBut (022100@1)I will hold on hope
    E (022100@1)     A (x02220@1)     EAnd (022100@1)I won't let you choke
A (x02220@1)    E (022100@1)     BOn (x2444x@1)the noose around your neck
     C#m (x13321@4)       A (x02220@1)       EAnd (022100@1)I'll find strength in pain
    C#m (x13321@4)    A (x02220@1)      EAnd (022100@1)I will change my ways
       A (x02220@1)     E (022100@1)           BI'll (x2444x@1)know my name as it's called again

(Instrumental interlude = Verse chords)

Verse 3:
Cause I have other things to fill my time
You take what is yours and I'll take mine
Now let me at the truth
Which will refresh my broken mind

Verse 4:
So tie me to a post and block my ears
I can see widows and orphans through my tears
I know my call despite my faults
And despite my growing fears

Chorus 2:
But I will hold on hope
And I won't let you choke
On the noose around your neck
And I'll find strength in pain
And I will change my ways
I'll know my name as it's called again

Verse 5:
So come out of your cave walking on your hands
And see the world hanging upside down
You can understand dependence
When you know the maker's hand

Pre-Chorus:  (same as chorus chords)
So make your siren's call
And sing all you want
I will not hear what you have to say
Cause I need freedom now
And I need to know how
To live my life as it's meant to be

Bridge (I have given the length of each chord in this part because there are no lyrics):

E// (022100@1)A/ (x02220@1)E/ (022100@1)E// (022100@1)A/ (x02220@1)E/ (022100@1)A/ (x02220@1)E/ (022100@1)B// (x2444x@1)(Repeat Once)

Chorus 3:
And I will hold on hope
And I won't let you choke
On the noose around your neck
And I'll find strength in pain
And I will change my ways
      A (x02220@1)     E (022100@1)           B (x2444x@1)         E////
I'll know my name as it's called again.

Note:  The final chorus is the same just the melody changes slightly when he goes "And I 
change my ways" etc.  The chords are identical but end on E since this is the tonic chord.
