This is the intro and verse - between the chorus and verse the song tranposes between A and Gb; at the bridge it moves to the key of C then to E and on to B for the rest of the song. I gave you a little bit of the song below, hope this helps, let me know if you have question. Don't Let the transitions through you off its a pretty basic song. Remember to practice songs you learn in every key. God Bless
