To play it more simple just go half-tone up or half-tone down..
Am,Em,F,C,Dm,G,Am,E, etc...
OR
Bm,F#m,D,Em,A,Bm,F#,etc..

But the correct tone is this:
 
   Bbm    Fm          F#   C#
I stand alone in the darkness
    Ebm       Ab      Bbm      F   
The winter of my life came so fast
Bbm      Fm          F#   C#
Memories go back to childhood
   Ebm      Ab    Bbm        
To days I still recall      

Bbm     Fm     F#   C#
Oh how happy I was then
Ebm           Ab     Bbm           F
There was no sorrow there was no pain
Bbm      Fm          F#     C#
Walking through the green fields
Ebm      Ab     Bbm
Sunshine in my eyes

Chorus
           F#         Ab
I'm still there everywhere
        C#    C#/C    Bbm
I'm the dust in the wind
        F#          Ab       Bbm
I'm the star in the northern sky

           F#      Ab
I never stayed anywhere
        C#    C#/C    Bbm
I'm the wind in the trees
           F#      Ab  Bbm
Would you wait for me forever ?
