Below are two ways to play the chords used throughout the ENTIRE song. The first is the 
chord way. The second is the barre-chord way. Both these ways are correct, some are just 
for others.


1.)        A minor          G Major           C Major         D Minor
e|(R)---0---0---0---0----3---3---3---3----0---0---0---0----1---1---1---1---(R)|
B|(E)---1---1---1---1---(3)-(3)-(3)-(3)---1---1---1---1----3---3---3---3---(E)|
G|(P)---2---2---2---2----0---0---0---0----0---0---0---0----2---2---2---2---(P)|
D|(E)---2---2---2---2----0---0---0---0----2---2---2---2----0---0---0---0---(E)|
A|(A)---0---0---0---0----2---2---2---2----3---3---3---3--------------------(A)|
E|(T)--------------------3---3---3---3-------------------------------------(T)|

If you want to mimic the high piano part used throughout the song, just play the D and G 
instead of the entire chord.

Experiment!

I gave you the chord progression, now do whatever you like with it. Enjoy.
