Watch the C Major Pentatonic online guitar lesson by Brad Carlton from Guitar Lab: Super Sustain
The goal of this lesson is to help you understand the C major pentatonic scale along the length of the third string. You will see in diagram one that the root and the fifth are in red. These two notes are your strongest tones and hence provide a framework upon which you can build the scale. The root is the strongest tone and the fifth is your second strongest tone.
There are only two different intervals in this scale when dealing with adjacent notes. The major second interval which is an interval consisting of one whole step(two frets), and the minor third interval which is an interval consisting of a step and a half(three frets). There will always be a major second interval between the following scale tones: 1 and 2, 2 and 3, and 5 and 6. There will always be a minor third interval between the following scale tones: 3 and 5, and 6 and 1. Memorizing these shapes will aid you when you transfer this linear map of the scale to a different string. And remember, these intervals will always remain the same no matter what key you are in.
This lesson includes a jam track over which you should practice playing this information. Apply all the techniques as demonstrated in the video with a goal of trying to keep the guitar ringing.
