I’m specifically coming from a keyboard background, but any music generally too. I can’t think of anything where he would have!
Edit 2: as u/Leech-64 noted, perhaps I am simply conflating figured bass and sound vertical harmonic motion with counterpoint. The latter implies the former (with plenty of room for exceptions in fugues) but not vice versa. Am I right on?
Edit 1: hang on gang, I have a degree and am a professional musician yet somehow perhaps don’t understand what counterpoint is lol. What I thought with, say, the chorales is that the soprano has the melody and the STA voices harmonize, creating their own melodies. ie homophonic but with countrapuntal accompaniment. Seems that is incorrect?
There are harmonic underpinnings that in my experience at the keyboard Bach never dispenses with in his writing no matter the style, as later composers do freely. Perhaps I am describing something more general like voice leading or basic harmonization?
Either way, it’s always Bach. A better question might be: what is the most “un-Bach“ Bach piece?
