More D-U-U-U goodness!
Bar 12 is where things get interesting - The patterns change a bit, finger-rolling is heavily implemented and we flip the picking pattern entirely (D-D-D-U). Be sure to FEEL the quarter note pulse as much as possible. This is very important when it comes to keeping you on track, even IF you flub a note here and there. The main thing is you're starting and stopping in the correct places.
