Pentatonic Scales - Concept 14 is a video guitar lesson presented by Andrew Ford and is sourced from Blues Bass Survival Guide.
Pentatonic scales are five note scales used in popular music. The two most common are the major pentatonic and the minor pentatonic scales. The intervals making up the major pentatonic are a whole step, whole step, minor third, whole step, and minor third. The intervals in the minor are a minor third, whole step, whole step, minor third, and whole step. So each is constructed of three whole step intervals and two minor third intervals. Let's play each scale, then afterwards play a riff based entirely on that scale.
