Thank you for the wonderful post. I was in the shower humming the Nomai theme from Outer Wilds, when two earworms came up simlutaneously: this, and the Little Fugue, and for some reason they comingled in my mind that I couldn't remember which melody was which, so I went googling and eventually found your post.

Excellent article and great analysis of the state of the fugue - your insight has motivated me to dig out some Bach from the old piano bench and give things a bit of a bash.

As a musician, stuck in a bit of a rut of late, this kind of thing really helps get the juice flowing again. I’ve spent 15 minutes churning through some fingering and activating old muscle memory I’d forgotten about completely since the piano lesson days, and tonight’s jam session with my band is going to have some new flavours to introduce.

Good stuff, thank you!
