“He just presses two side by side and it sounds good” a guitarist once said while I worked with him on a piece. I find that a bit disappointing, too. In other times such intervals would have been forbidden, now we’ve gotten used to them and find them interesting. Where does it stop? And what is there, other than our random spot on this progression?
