Watch the Minor Pentatonic online guitar lesson by Bruce Arnold from Jazz Guitar for Beginners
The Minor Pentatonic is used over a minor chord and is also one of the most used scales in music. This is because of the close relationship to the Dorian and Aeolian scales and its ability to be used over a minor tonal center.
Remember think the notes or the degrees when learning the Minor Pentatonic scale. If you are practicing A minor Pentatonic, use a jam track for A-7 as a backing track so you hear the scale in the right relationship.
You should of course know this scale in all keys. We are using the Aminor to G to F chord progression for this example because we hear all three chords in one key, but any minor or sus4 vamp could also be used.
