Scherzo, how do I put the joke into the music?

Feb 24, 2019

This is my first phrase in my scherzo. I haven't uploaded it yet because I just have that one phrase. The eighth notes in the right hand and the focus on Bb at first, making it sound like it is in Bb major instead of F major, despite the E naturals makes the right hand, I think sound like a true scherzo, at least until the cadence lands on F. The left hand however, I think diminishes the scherzo quality because it is a simple quarter note bass line until the cadence is reached and there are 2 dotted quarters.

I am writing this scherzo as an isolated scherzo as you can probably tell from the title in the image being Scherzo in F. So how do I put the joke into the music? If you can't tell already, I kind of going with a Haydynesque approach to this scherzo, in other words, really making it sound like a joke instead of one of Beethoven's more serious sounding scherzos.
