Hi there! I'm a huge fan of Hannah Montana, and I think this song is beautiful.
The strumming is pretty hard to match with the words, so just listen to the song 
to know when to change chords. (:
Also, for the 'C' chords, you can play with it a little and make it Cadd9 instead. 
It sounds better. (:
So here it is. Enjoy!!
