Watch the Minor Pentatonic Scale Forms online guitar lesson by Brad Carlton from Guitar Lab: Power Chord Blues Riffs
Diagrams one through eight show the A minor pentatonic scale in various positions on the fingerboard. The roots of this are labeled in red and the remaining three scale degrees (b3, 4, and b7) which form the A minor pentatonic scale are labeled in black. Diagrams nine and 10 show the analysis of the five notes in the A minor pentatonic scale when you are playing over the IV7 chord (D7) and the V7 chord (E7). For the 20 examples presented in the tablature, you will be using diagrams one and two. You will then be able to transfer these riffs to other areas on the fingerboard by using these other scale forms. It is important that you memorize the scale degrees in diagrams one, two, and three as you go through each riff example. This will allow you to transpose to any key and also build on the information presented in this course. Your ultimate goal will be to memorize all five scale forms in terms of scale degrees.
