Watch the Building The Minor Pentatonic Scale online guitar lesson by Jason Loughlin from Blues Connections: Minor
First let's look at the minor pentatonic formula: Root-b3-4-5-b7. We're going to build the scale off of a single string so we can see the intervallic relationships between the scale degrees. You can create a minor pentatonic off of any note if you follow this formula: minor 3rd, whole step, whole step, minor 3rd. A minor 3rd interval is one and a half steps. As you're going through the scale, focus more on what scale degree you're on rather than the note's name. We're going to build this scale off of an A, D, and E since these are the keys we'll need for the course.
