[Estrofe]
                       C     Em     D 
When I met you in the summer 
                Am     Bm     C 
To my heartbeat sound 
            C     Em     D 
We fell in love 
                     Am     Bm     C 
As the leaves turned brown
[Estrofe]
               C     Em     D 
We could be together baby 
                      Am     Bm     C 
As long as skies are blue 
             C      Em     D 
You act so innocent now 
                Am     Bm     C 
But you lied so soon 

When I met you in the summer
Then it just repeats. The rhythm is something like two strums on the C and Em, then 
one strum on the D, two strums on the Am and Bm and one on the C.
