An Artist embodying Classical Aesthetics is one who sees a specific "truth" and seeks to provide order and harmony in his/her Artistic universe. An Artist who embraces Romantic Aesthetics would become enraged at the prospect of being deemed Calculated by a Critic, presumably because it conflicts with the core Romantic principle of Authenticity.
The role of the Market in all this is to encourage Artists who can understand while ALL POPULAR MUSIC EMBODIES Classical Aesthetic principles or order, harmony and technical excellence, while paying lip service to the Romantic principles that the contemporary audience for Art desires from it's Artists: Alienation, Isolation, Dissatisfaction with "the way things are." A specific Artist given commercial success will have to adjust his or her principles with the growth of an Audience: As an unknown, it is best to embody Romantic Aesthetic principles to appeal to the "hard core" fans of a particular genre, much in the same way a Politician will "secure his base" in a Primary campaign, before "moving to the center" for a general election.
interesting question about time.Does time have an influence on whether something is 'classical' or 'romantic' according to this model? Like I love jungle which was obviously 'romantic' at the time, but I came to it years later and well after it had been established so it was an existing well-defined structure by the time I got into it.
I'd say even "when the music was new and had no rules" jungle pretty quickly codified to an extent and had established cultural parameters. so in a sense it was about proper tunes.
turtles all the way down, broIt all ends up being proper tunes eventually, doesn't it?
