I found a jazz progression in Chopin- HA!

So, I know there are some people on this forum who, in their ignorant, snobby mindset, believe that jazz is just banging chords. Pop, that could be the case (I wouldn't really know). But jazz has lots of delicacy, and to prove it, I show you the most essential tool of jazz, like, ever.

This is the Mazurka in G minor, Op 67/2 . At around 0:40, or right at the beginning of measure 21, there is a jazz circle progression, followed by one tritone substitution.
Ha!!!

This seems stretching things a bit. It's simply a descending chromatic sequence. That such a progression could also occur in jazz (of course jazz borrows from classical) does not make this
a jazz progression imo.
Then again I've heard it stated that Bach was the first "jazz musician"

My point was the many of the harmonies are the same from classical to jazz. My teacher also once said that he was working through some of the Brahms Intermezzi and found plenty of jazz chords.
But yes, it's a circle progression (G7-C7-F7-Bb7-Eb7-Ab7-Db7-Gb7). I also was wrong about the tritone sub, it's just returning to a secondary theme, this time on a C7 instead of Fsus4 (I think that's it? F-Bb-Eb?).
Interesting thought about Bach. I've also heard that Baroque and romantic music have the most in common of the three "main" eras of the genre of classical music.
