Occasionally in the final choruses there is a hammer on on the second fret of the D string in the G chord.
[Intro]
F C G Am G F C G
[Verse]
F C
Hate casts a long shadow
G Am G
I know that I lie in it
F C G Am G
And let it rule my mind from time to time
F C
Escaping an old battle
G Am G
Clings on like a vine to me
F C G
Whispers dirty lies in my ear (and I know)
C F
We didn't start this fight
C E7
And I won't let it rule my heart tonight
[Chorus]
F
I can change
C
I can change
G Am G
I can still change
F C G
I can still change
F C G Am G F C G Am G
[Verse]
F C
Tracing an old pattern
G Am G F C G Am G
Drawing the lines from where I am, and from where I wanna be
F C
Forget that old adage
G Am G F C G
That history continues to keep us from the world we wanna see
C F
I am scared that I won't get it right
C E7
But fear won't rule my heart tonight
[Chorus]
F
I can change
C
I can change
G Am G
I can still change
F C G
I can still change
F
I can change
C
I can change
G Am G
I can still change
F C G
I can still change
F
I can change
C
I can change
G Am G
I can still change
F C G
I can still change
F
I can change
C
I can change
G Am G
I can still change
F C G
I can still change
