Watch the 4 b3 3 1 Move online guitar lesson by Brad Carlton from Guitar Lab: Riff Generator
This lesson focuses on the four following tones: 4 b3 3 1. Diagram 15 shows the layout of these four tones in all four octaves. You should view it two different ways: all four notes on the same string or three notes on a higher string and the root on the next lowest string. You will learn various warm-ups which will enhance your left-hand technique while drilling through these tones. These include hammer ons, pull offs, legato slides, bends and releases. I suggest learning this formula in each of the four octaves that are available on all string groups. This will offer you the option of playing the same notes on different strings for tonal and/or technical reasons.
I will explain in the video how this lick implies a IV to I chord change.
I will show you various ways of combining your left-hand techniques to create different riffs with the same four notes.
