In this 2nd section we see the patterns that have already been established ascending by step through each diatonic chord until we reach the highest point of the fretboard that we can go.
Technically, once you have mastered the right hand pattern this should present no problems for you although you need to keep a solid rhythm throughout so whatever you do keep that aspect of this study at the forefront of your mind at all times. As always, don't attempt anywhere near the full tempo unless you are totally comfortable with the technique that this study demands.
