In Secrets of Tasty Riffs & Solos, one of the tricks I taught was how to use two strings and climb up or down the fretboard in patterns of thirds. This is a great way to move between scale patterns, it sounds really cool and melodic, and it can quickly get you from one end of the fretboard to the other.
What’s not to like?
Anyhow I was just watching some Albert Cummings (do it!) and I saw him pull the exact same trick, and thought I’d post the video to give you another practical example of how this sort of thing can be used in a song.
Right around 4:06, you’ll see he starts using these patterns on the 1st and 2nd strings to rip down the fretboard, from right near the top to the bottom, then he uses different strings and different patterns (looks like inverted thirds on 1st and 3rd strings to me) to begin his climb back up.
