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.

*Cadd9-  032033
*G- 320033

Capo 4

     G         Em9     C          Em9
I see trees of green, red roses too
Am7        G      D         Em
I see them bloom, for me and you,
      Cadd9*               Am7     D7        G D 
And I think to myself, What a  wonderful world.
     G         Em9    C          Em9
I see skies of blue, and clouds of white,
Am7                 G        D           Em         
The bright blessed day, the dark sacred night,
      Cadd9*           Am7       D7       G     C D G                        
And I think to myself, what a wonderful world

    D7                        G
The colors of the rainbow, so pretty in the sky
    D7                   G
Are also on the faces of people goin' by
      Em              D               Em9        *Cadd9
I see friends shaking hands, saying, "How do you do?"
Em             G2       Am7  *G       D7 (let ring)     
They're really saying,  "I   love    you."       I hear

G      Em9     C         Em9
Babies cry, I watch them grow
Am7                 G         D         Em
They'll learn much more than I'll ever know,
      *Cadd9           Am7       D7     G    C D G
And I think to myself what a wonderful world

       Am7             D7                 G (let ring)
Yes I think to myself, what a wonderful world.
