The song is in Bb. Here are the chords
intro/Verse:
i did my best to notice when the call came down the line
upto the platform of surrender i was brought but i was kind
and sometimes i get nervouse when i see an open door
close your eyes clear your heart cut the chord
Chorus:
are we human or are we denser
my sign is vital my hands are cold
and im on my knees looking for the answer
are we human? or are we denser
bridge:
Eb F F#m (open 5th optional) Gm
will your system be alright when you dream of home tonight
ther is no message were recieving let me know is your heart still beating?
