Just a comment to say classically trained Europeans have a different way of thinking about these chords. I have a good friend who's a graduate of the Warsaw Conservatory in piano. I had to teach her "our" names for these chords. She didn't know anything about Maj7's, 7b9's, tritones or any of that. People were giving her fake book charts and she didn't know what to do with them. One time I played a recording of a Chick Corea passage for her because I wanted her to show me what he was doing. To my ears this was a very complex thing and I figured it might take her a bit to figure it out. It took her all of 10 seconds and I was just floored. She has unbelievable ears and told me it was just part of her training. I asked her what she called these changes and she shrugged and said they were just simple functions like any idiot knows that. She's actually not arrogant at all it's just that her level of training is such that she can make almost any music pro feel like an idiot sometimes. She's now a private teacher to mostly very good pianists in the studio industry. She can sit down with anybody regardless of their level of proficiency and show them how to improve their technique.
