Sorry about the other one hour lecture link...but although it could be a bit difficult to follow, the lecturer was much more engaging than at that other link, and near the end provided some insight as to how some of Bach's compositions could interface or be made to link (if just in the imagination, and by some example of principle) with the questions and discussion as to philosophy of math, which is why I sent those.
I do apologize for not having provided better explanation for the links.
I made the (possible) mistake of listening to some Stevie Ray Von a short time back... Talk about an ear worm. I've been hearing passages of his treatment of Hendix's Little Wing going through my mind for days. Part of it is that like many people, I am well enough acquainted with the original to be able to hear the departures, with those being like much like some jazz, while staying within R&B/Rock, blending those genres.
It's all a matter of taste and taste is taught, usually.
I don't doubt that in 1000 years from now, classical will still be around. I don't know about jazz. Jazz enthusiasts are positive that it will be; I'm not so sure.
