This article has some good content, but to be honest, I expected more from the title. When discussing generative art, generative music and sound art should also be considered. I've done some research on generative music while developing Glicol.
Simple randomness can create some "embellishments":
Before next token prediction become the only meaning of “generation” generative art was a way of describing art automatically being generated. It never sounded good so we always thought of it as a visual medium.
My whole job is big-model GenAI music stuff and I'm still unclear what counts as "generative." Are loops in Ableton generative? What about that GarageBand drummer thing?
The traditional concept of generative music was that it was different each time and varied/developed/evolved while playing.
So it's generative in the way "generative design" is, but not oriented towards optimising for a goal, if that makes sense.
I don't know about Ableton loops but I've met some drummers like this but they are usually not all that popular. So I am guessing that is not what GarageBand is aiming at, in quite the same way. ;-)
Though perhaps that is generative in the sense of optimising towards a goal; I've not used it.
Eno's work was initially done with the Koan and I think he ended up in a sort of symbiotic relationship with the developers. It was a big deal for a while in computer music magazines in the 90s.

Logistic maps can also be used as random note generators:
