Cómo paso esta canción a Tonalidad Menor?

Soy un guitarrista novato y siento cierta curiosidad por pasar las canciones que estan en tonalidad mayor a tonalidad menor... No sé si hay algún programa que lo haga automaticamente, sin emgargo... Si me quieren ayudar a pasar esta canción lo agradecería

Intro:  A E7 D E   x2
Verse 1: 
          A D
There's a line that you cross
          A D
When you find out that you're lost 
          A D 
When your world is closing in
          A D
And it crawls under your skin
Bridge: 
          F#m   E      A              
And the heart's always blind
          D         A       E           
When it's in this state of mind
Chorus:         
           A
There's a burning light in this town
     E                                D
For every heart that's broken down tonight
        E7
Here tonight 
           A
You're stranded out there in the rain
      E D
And you just can't see past the pain tonight
                      E7 
You've fallen from Graceland
D             A                F#m E A F#m E A
Fallen from Graceland
Verse 2 (same chords as above):
When you're too proud to crawl
It keeps you back against the wall
You wanna die, but you live
With nothing left to give
Bridge:
            F#m  E      A
And there's no place to hide        
             D      A      E    
When you're tangled up inside 
Chorus
Chords through solo:  A D A D              
Bridge
Chorus
Outro:
A
Fallen...
E 
You've fallen...
       D E
from graceland... Tonight
  A       E                              D                    
Fallen... Fallen, fallen, fallen from Graceland... Tonight
 E
Tonight...
            A 
There's a light
                 E
A bright light burning 
    D E
For every broken heart in this world tonight              
        A       
Deep inside 
                E 
Yes, there's one light burning
            D E
That will lead you throught the storm tonight
 A
It's gonna be alright...
Fade away mixing up A, E, D:
Be alright, yeah
Gonna be alright, yeah
It's gonna be alright
(Oh, it's gonna be alright, tonight)
