Josh Groban - Brave chords

Josh's new single :Brave
Key of:E
this song gave me fits because the chord changes dont necessarily follow a 
specific pattern throughout the song and the violins are so present in the song 
its sometimes hard to hear the chord changes. If youll listen real closely, you 
can heat the guitar play the chord changes and thatll help with the timing


violin part that is played at intro and repeatedly throughout song: 
e------------------------|
B------------------------|
G------------------------|
D------------2-----------|
A-2--0h2--0--------------|
E------------------------|

E
Wake up, wake up, the sun cannot wait for long.
                                     A    E        
Reach out, reach out before it fades away.
B                                    A    E    
You will find the warmth when you surrender.

Smile into the fear and let it play.

You wanna look away, look away but you stay cause its all so close.
          E             B           A
When you stand up and hold out your hand.
       E               B          A           
In the face of what I don’t understand.
