Riff
Dunwich child,
Riff
You know not your fathers' name.
Riff
Dope numbs the pain,
A                  E         Eb
Ascend dark wooded hills to kane.
Riff
Your mothers' witches,
Riff
Burnt at the stake for sorcery.
Riff
You were conceived,
A               E     Eb
Upon the altar, rites obscene.

C#        E       A      E Eb
Child of Dunwich rise
C#       E       A      E Eb
You have your fathers' eyes
C#        E       A      E Eb      C#
Child of Dunwich rise
E       A          E   Eb
End the world that you despise

Riff

Riff
Dunwich child,
Riff
Of whispered past now they'll learn.
Riff
High on the hill,
A                   E           Eb
Black clouds gather now they'll burn
Riff
Bay at the stars.
Riff
"Why was I born at all?"
Riff
Hear voice of doom,
A                   E           Eb
From other worlds your fathers' call.


C#        E       A      E Eb
Child of Dunwich rise
C#        E       A      E Eb
You have your fathers' eyes
C#        E       A      E Eb      C#
Child of Dunwich rise
E       A          E   Eb
End the world that you despise

A        E           Riff
