The minor pentatonic scale is based on the minor scale. It uses the 1, 3, 4, 5 and 7 notes from a minor scale. For example, the C pentatonic minor would use C, E-flat, F, G, and B-flat. This scale is one that’s commonly used in blues solos. Combine it with the 12 bar blues or a 7th chord progression and you’ll have a cool sounding piece.
