Treehouse

C
I have built a treehouse
G
I have built a treehouse
Am
Nobody can see us
F
It's a you and me house


Same chord progression here, twice. 
A bunch of "ooooooh"'s for vocals.

C
I've been climbing rocks and stones
G
Been collectin' broken bones
Continúa después del anuncio
Am
I've been swimming 'cross the lakes
F
Just to find this perfect place

C
I got lost into the woods
G
I got covered up in mud
Am
I've been going through a lot
F
Just to find this perfect spot


^Then you repeat all of that except 
for the "Ooooooh" section^

Then it goes into the section with 
the same lyrics as the chorus, only 
sung with a
rhythm. This is the only part where 
I'm not sure if the chord 
progression used in the
of
song applies. There doesn't seem to 
be much instrumentation other than 
percussion and
though.

The final section, the first 2 lines
 of the chorus only slower:

C           G
I've built a treehouse
Am            F
And no one can see us
