That doesn't answer my question because C maj scale has the same notes as A min. And you can't do the same thing with F min and G maj. It would be E min and G maj because they have the same notes in them. Let me ask my question again: This question is about pentatonic but it also applies to most of the 7 note maj scales and its modes, but to keep the question simple it is about pentatonic.

E maj chord - E maj pentatonic -works
E min chord- E min pentatonic- works
Now here is my question.............

E maj chord - E min pentatonic-works even though notes don't fully match( major 3rd and minor 3rd)
E min chord - E maj pentatonic-Does not work. Why does min pentatonic work over a maj chord yet the reverse of that doesn't work.
