These are by no means the original or "correct" chords for this song, this is 
simply the way I play this song on my acoustic guitar. I think it sounds pretty 
nice, and, well, pretty. Some of these chords I don't know the name of so I just 
listed them below. Sorry if this is crappy- this is my first tab.

*Fadd9-  032033
*F- 320033

Capo 4

     F         Am9     F          Am9
I see trees of green, red roses too
Dm7        F      G         Am
I see them bloom, for me and you,
      Fadd9*               Dm7     G7        F G 
And I think to myself, What a  wonderful world.
     F         Am9    F          Am9
I see skies of blue, and clouds of white,
Dm7                 F        G           Am         
The bright blessed day, the dark sacred night,
      Fadd9*           Dm7       G7       F     F G F                        
And I think to myself, what a wonderful world

    G7                        F
The colors of the rainbow, so pretty in the sky
    G7                   F
Are also on the faces of people goin' by
      Am              G               Am9        *Fadd9
I see friends shaking hands, saying, "How do you do?"
Am             C2       Dm7  *F       G7 (let ring)     
They're really saying,  "I   love    you."       I hear

F      Am9     F         Am9
Babies cry, I watch them grow
Dm7                 F         G         Am
They'll learn much more than I'll ever know,
      *Fadd9           Dm7       G7     F    F G F
And I think to myself what a wonderful world

       Dm7             G7                 F (let ring)
Yes I think to myself, what a wonderful world.
