This song is beautiful. Just... so good.
Anyway... it's easy to play, which just adds to the beauty of the song :)
You can play it in standard tuning, but i found that it is actually easier to play it 
with the 6th string tuned down to D instead of the normal E.
Here's an easy way to tune down the 6th tring to D - match the 7th fret note on the 6th 
string to the open 5th string. Voila! You have a D 6th string :)
So the tuning is:
E----
B----
G----
D----
A----
D----

Here we go!
