Try Using these scales over a 12 bar sequence in  A major or A minor. And here’s the magic bit: you can also use them for anything in the key of C major. Why? Because every pentatonic minor scale is also the pentatonic major of the note three semitones higher (A to C = 3 semitones). It is the chord sequence that will decide whether the scale is heard as A pentatonic minor or C pentatonic major.
