[Estribillo]
C 
 You'll be the saddest part of me 
Em 
  A part of me that will never be 
Am 
Mine, it's obvious 
G 
 Tonight is gonna be the loneliest 
C 
 You're still the oxygen I breathe 
Em                               Am 
  I see your face when I close my eyes 
  
It's torturous 
G 
 Tonight is gonna be the loneliest
[Estrofa]
C 
 There's a few lines that I have wrote 
Em                                Am 
  In case of death, that's what I want 
                  G 
That's what I want 
C 
 So don't be sad when I'll be gone 
Em                                   Am 
  There's just one thing, I hope you know 
            G 
I loved you so
[Pre-Estribillo]
       C 
'Cause I don't even care about the time, I've got left here 
    Em 
The only thing I know now is that I want to spend it 
     Dm 
With you, with you 
  
Nobody else here 
G 
 Tonight is gonna be the loneliest
[Estribillo]
C 
 You'll be the saddest part of me 
E 
  A part of me that will never be 
Am 
Mine, it's obvious 
F 
 Tonight is gonna be the loneliest 
C 
 You're still the oxygen I breathe 
E                               Am 
  I see your face when I close my eyes 
  
It's torturous 
G 
 Tonight is gonna be the loneliest
[Estrofa]
C 
 I'm sorry but I gotta go 
Em                                  Am 
  If you'll ever miss me, give this song 
        G 
Another go
[Pre-Estribillo]
    C 
And I just keep on thinking how you made me feel better 
    Em 
And all the crazy little things that we did together 
Dm 
In the end, in the end 
  
It doesn't matter 
  G 
If tonight is gonna be the loneliest
[Estribillo]
C 
 You'll be the saddest part of me 
E 
  A part of me that will never be 
Am 
Mine, it's obvious 
F 
 Tonight is gonna be the loneliest 
C 
 You're still the oxygen I breathe 
E                               Am 
  I see your face when I close my eyes 
  
It's torturous 
G 
 Tonight is gonna be the loneliest
