Hello!!! We're flying to diatonic and beyond!!! Actually beyond Here one I've stumbled on a non-diatonic progression in a pop song and I don't understand how it works :-\ : i | V | bIII | IV V :|| (or in key of A : Am | E | C | D E :|| ) Could you please explain it? More generally, I'm looking for some examples on non-diatonic (containing chord notes out of major scale) chord progressions in pop, soul or rock. Rather simple 3 or 4 chord progression, used as song basis, and that are not diatonic. They sound hip. I like it Thanks!!!
