What We Found for minor
When we add tones to A minor Pentatonic, we get different modes. We will add Bb-F, B-F, & B-F#. Each of these 3 hold one of the locations for minor chords in the Major key system. [iii, vi, ii in the order below]. There are other possibilities too. We are staying within the derivatives of the Major key system.
Basic mods include EMaj7, E7, Em7, Em, Eadd9.
We've drawn some lines, but all of them could be connected. Use the chord wheel and meander around. Let your eyes fall onto next chord you will change to. Go in every order imaginable. Connect everything to everything.
