Amazing song!! For the strumming, I just do: down down up down down up down down up down 
down up.
I tend to put capo on 5, but that's just for my voice. Play around with it. These are 
chords I use, but you don't have to use them.
Standard tuning.
Capo: 5 [for me, use what you want]


G         D
Somewhere over the rainbow
Em     C
Way up high
Am        Em
There's a land that I heard of
D              Em  C
Once in a lullaby
G         D
Somewhere over the rainbow
Em        C
Skies are blue
Am      Em                      D
And the dreams that you dare to dream
               Em    C
Really do come true

G
Someday I'll wish upon a star
D
And wake up where the clouds are far
Em     C
Behind me
G
Where troubles melt like lemon drops
D
Away above the chimney tops
       Em           C
That's where you'll find me

G         D
Somewhere over the rainbow
Em        C
Bluebirds fly
Em        Am
Birds fly over the rainbow
D                    Em  C
Why the oh why can't I

G
If happy little bluebirds fly
C
Beyond the rainbow
D                 G
Why, oh why can't I?
