This is not OT btw. 'Joint' is 'Fuge' in German = fugue.
Now that would be an interesting topic: musical form, thematic development, reverence for purposeful rules, and beauty by design. Every piece I've posted in the last two years has these; every one includes design, form, a general scheme - including the improvisations. None of it is experimental. On the occasions I've "experimented," I haven't liked the results.
I've composed about twelve fugues, but I'd like to return to the form and compose many more. Unfortunately, the pedal playing in the pieces is so involved that I'm not able to perform any of them on my current set up. That little Hammond XPK 200L pedalboard is the biggest musical obstacle I face. But fugues sound exceptional on synthesizer, especially with an Oberheim-ish PWM patch. Such music requires full length pedalboards and keyboards, which is one reason I simply can't work with anything less.
Paul, I believe you have a piece on your YouTube channel or somewhere else that's a sort of fugue or passacaglia - isn't that right?
