Watch the b3 2 1 Move online guitar lesson by Brad Carlton from Guitar Lab: Riff Generator
This lesson focuses on the three following tones: b3 2 1. Diagrams 1a through 1d show the layout of these three tones in all four octaves. The layout involves all three notes residing on the same string. The intervals are as follows: minor second between the b3 and the 2, and major second between the 2 and the 1. 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. By learning this three note group according to which octave you're in, you will view the unison groupings on adjacent strings. This offers you the option of playing the same notes on different strings for tonal and/or technical reasons. Each of these four diagrams show the unison groupings of this three note formula.
I will show you various ways of combining your left-hand techniques to create different riffs with the same three notes.
