@ajroach42 @mrgah With Haydn, I’m thinking especially of the six quartets published as Op. 20.
In Op. 20 #2, the second movement is a mashup of recitative and fantasia where you never know what will come next.
In Op. 20 #4, I challenge you to find the downbeat in the third movement.
This recording captures the daring in the music: https://open.spotify.com/track/5Zw3zbfoSG1r3H43GDX1T8?si=TCQv9mMpSOKbkscZBo586w
