The song is in standard tuning. listen to the song for the exact rhythm but 
the signature of the song is 3/4. also the bassnotes are all quarter notes 
but most of the melody is all doublets. ( only the 13th bar is an exception)

The notes between [...] are notes he sometimes plays very lightly because it 
fits in the rhythm, but if you don't play them at all it sounds just as 
accurate. in fact, if you do choose to play them, you must play it very 
subtle and soft, it shouldn't stand out.

And this goes on for the entire song.

I'm sure it's a 100% accurate, but I could always be wrong so please feel 
free to leave your comments and criticism. Good Luck!
