Everyone says that the tuning of this song is Drop D but i think it sounds better a 
half-step down (Eb Ab Db Gb Bb eb) sounds fine either way. Hope you enjoy the song.

On the 6^p6 what you do is you hit the the G string on the 6th fret bend it then 
pull-off of it.

You do the same with the A string and 7th fret.

On the 4h5p4 you hit the D string then hammer on to the 5th fret then pull-off of the 
4th fret.
