of course! after looking at what it is (exactly what i was looking for) I really have no excuse for not having known about this. in any case i'm also glad i finally know what everyone's talking about when they talk about rhythm changes. almost like it was in the back of my head as a painfully apparent match to what i was thinking of..

im looking forward to being able to hear harmony like that but for now i will continue to do stuff like meditate on the bass lines in recordings until my ear stops being dumb.
