Slash chords/ 4/9 dominant chords work on everything?
First time posting, hello everyone. I was playing around D’Angelo Untitled changes, which to my ears sound like: D(7M), A-7, G(6/9 - 7M), C of some sort. Initially I thought a classic jazzy C13 was the best option (guitar player here), but I kept hearing an F so at some point I tried the classic guitar slash chord, that is in this case Bb with C on the bass or C7 sus 9. That is supposed to resolve on the D, and that is totally fine. Then I started to realise that moving the same chord up or down one tone, or cascading it up or down tone by tone, no matter where you are, you can always then resolve to the D with the same effect. This is very much like what you can do with diminished chords moving them a minor third away, or dominant 5# chords moving them a tone away. So I wondered how is this thing called in music theory? Does any of you have any relevant example of this? I think that for the dominant sis/9 chord, Never too much or On Broadway can be good ones
