Watch the The Major Pentatonic Formula online guitar lesson by David Wallimann from Guitar DNA: Pentatonics
Now that you are comfortable with the minor pentatonic scale, let's study the Major pentatonic scale! Before memorizing the 5 positions, take a look at the Major pentatonic scale formula: 1-2-3-5-6. Notice that the 3rd is Major. The 3rd determines the nature of a musical element.
Playing the Major pentatonic positions should come very naturally to you because the Major pentatonic scale and the minor pentatonic scales are related to each other. Practice over the provided backing track and master those positions!
