Watch the Four Note Patterns online guitar lesson by Brad Carlton from Guitar Lab: Getting to Know the Neighbors

Now we move to four note patterns in which the target note is the upper chord tone in the arpeggio. What I mean by this is that each four note group is organized as follows: approach tone, chord tone, approach tone, chord tone. Since the second and fourth notes in the pattern are always notes out of the arpeggio, this group of patterns will always use the higher pitched chord tone as the final destination.
