Here is what I found when I listened to it. Its all by ear.

G      F                 G
I hear your voice on the wind
    G      F        C      G
And I hear you call out my name

 G                      F      C
"Listen, my child," you say to me
 G                      F    C
"I am the voice of your history
G                   F      C
Be not afraid, come follow me
G                        F   C   Am
Answer my call, and I'll set you free"

Am                    C            G
I am the voice in the wind and the pouring rain
Am                     C          D
I am the voice of your hunger and pain
Am                  C         G
I am the voice that always is calling you
Am              C        D
I am the voice, I will remain

Repeat Am, C, G  Am, C, D for the rest of the verses.

I am the voice in the fields when the summer's gone
The dance of the leaves when the autumn winds blow
Ne'er do I sleep thoughout all the cold winter long
I am the force that in springtime will grow

I am the voice of the past that will always be
Filled with my sorrow and blood in my fields
I am the voice of the future, bring me your peace
Bring me your peace, and my wounds, they will heal

I am the voice in the wind and the pouring rain
I am the voice of your hunger and pain
I am the voice that always is calling you
I am the voice

I am the voice of the past that will always be
I am the voice of your hunger and pain
I am the voice of the future
I am the voice, I am the voice
I am the voice, I am the voice


thats what I heard. Enjoy!
