Intro:
(listen to the song for the strumming pattern) 
B F# G#m F# E F# B   x2

Verse1:
        E                            G#m
In the dark, in the darkness you will find
E                            G#m
Dirty little secrets we all hide
E                           G#m
Cause we all have, a darker side
   E                                   F#
A place we keep where no one else will find...

Chorus: (same as intro)
       B         F#       G#m        F#     E       F# B
Cause everybody wants to hide their secrets away
B      F#        G#m     F#      E    F#  B
Nobody wants to stand up to the pain       but i will...
E     F#         C#m
stand up to the pain
E     F#           C#m
wake up and fight again... if you could...
E          G#m              C#m
Dance with me through this rain...
          E     F#        C#m
We would fight... fight again...  fight again 

(repeat intro)

Verse2: same chords as verse 1

In the back, in the closets of your mind
That's where skeletons and dirty secrets hide
And i lay down, my insides
And leave them on display for you tonight...

...Chorus

Bridge: 
listen to the song for the rythm, but the chords are: E G#m(quickly) C#m F#

All my life i hide my secrets away... in the dark, in the dark in the dark...
We all try to hide our secrets away... in the dark in the dark in the dark...

E     F#         C#m
stand up to the pain
E     F#           C#m
wake up and fight again... if you could...
E          G#m              C#m
Dance with me through this rain...
          E     F#        C#m
We would fight... fight again...  


       B         F#       G#m        F#      E        F#    B
Cause everybody wants to hide their secrets away and that's okay
B        F#       G#m     F#     E         F#    B
Nobody wants to stand up to the pain and fight again...
