Intro: Well worth learning the opening even if you don’t bother with the rest of it. It’s the easiest part of the song.
Verse: Here’s where things get tricky. A lot of quick alternate picking to deal with. Make sure you’re fretting the E-string with you pinky for the G minor chord in bar 11. That’ll mean you’re in position for the quick hammer-on and pull-off between bars 12 and 13.
Chorus: The trickiest part of the song comes in the transition between the Ab and the Eb. You can make it easier by releasing the Ab chord rather than letting it ring. That’ll give you time to prepare your index finger on the A-string, 1st fret.
Break: Just the second half of the intro played a few times. Build up the volume here to increase the pull back to the chorus.
Outro: A key change right at the end. Which does make it trickier to play. The upside is you can just slow it down and call it ritardando and people will think you’re fancy.
