This song is in standard tuning.
This song is AMAZING.  Thank you Keith Urban.

Try to integrate the bar chords, especially during the chorus because you can imitate 
sound gaps better than when using open chords.  First time poster, so be nice.

Also, Thank You to all the Service Men and Women out there.

Bm (x24432@1)                    EmAll (022000@1)I saw was smoke and fire
               DI (xx0232@1)didnt feel a thing
A (x02220@1)                GBut (320003@1)suddenly I was rising higher
Bm (x24432@1)                   Em (022000@1)                DAnd (xx0232@1)I felt like I just made, the biggest mistake
       A (x02220@1)                     EmWhen (022000@1)I thought about my unborn child

A (x02220@1)                       EmWhen (022000@1)I thought about my wife, the answer rang out clear,
                   Afrom (x02220@1)somewhere up above
                   Em (022000@1)                               GNo (320003@1)greater gift of man, than to lay down his life for love

G (320003@1)D (xx0232@1)     And I wonder,
A (x02220@1)             D (xx0232@1)   GD
would I give my life,
A (x02220@1)                D (xx0232@1)        GD
Could I make that sacrifice
A (x02220@1)                           D (xx0232@1)                  GWhen (320003@1)it came down to it could I take just a little blood,
      AYes (x02220@1)I would for you.

Bm (x24432@1)                EmBaby (022000@1)you dont understand,
                          DI (xx0232@1)dont understand it all myself,
              A (x02220@1)                      GBut (320003@1)theres a brother on my left, and another on my right.
Bm (x24432@1)                         EmAnd (022000@1)in his pockets just like mine,
                 D (xx0232@1)       A (x02220@1)                        GHes (320003@1)got a photograph, and theyre waiting for him back home.

AAnd (x02220@1)its weighing on my mind.
                     Em (022000@1)                  AI (x02220@1)dont want to be a hero, I don't want to die,
                      Em (022000@1)                    GBut (320003@1)right here in the moment, you dont think twice.

G (320003@1)D (xx0232@1)     And I wonder,
A (x02220@1)             D (xx0232@1)   GD
would I give my life,
A (x02220@1)                 D (xx0232@1)       GD
Could I make that sacrifice
A (x02220@1)                           D (xx0232@1)                  GWhen (320003@1)it came down to it could I take just a little blood,
      AYes (x02220@1)I would for you.

A (x02220@1)                          EmYou (022000@1)dont think about right.
                             AYou (x02220@1)dont think about wrong.
                           Em (022000@1)              DYou (xx0232@1)just do what you gotta do to defend your own.
A (x02220@1)                     Em (022000@1)  DAnd (xx0232@1)I would do the same, for you.
