Yes. The first precept for art is that it must imitate nature, which means it must conform to forms and structures which exists within the realms of what is humanly perceivable. Those forms can be as complex or as simple as you want, they still need to follow basic structural precepts.
For starters, "progress" isn't the principal function of art and indeed many of the greatest composers in history made a sour name for themselves by actively resisting change which, if not irrational or unusual they probably saw as indulgent and banal. That said, while it is true that all innovation has met it's due share of general rejection and mistrust, it does not stand to reason that everything that generates rejection or mistrust will, nay, must eventually lead to general acceptance and confirmation, and just because innovation was seen as "irrational" at first it doesn't imply that it actually ever was, unlike many modern compositions, which ARE irrational, and will stay that way for ever.
precept (noun)
1. a commandment or direction given as a rule of action or conduct.
2. an injunction as to moral conduct; maxim.
3. a procedural directive or rule, as for the performance of some technical operation.
Your definition of art as something that
needs to follow any sort of guidelines is the worst kind of high school humanities class dookie I've ever heard. The definition of art in the same dictionary is a little more convincing:
art (noun)
the quality, production, expression, or realm, according to aesthetic principles, of what is beautiful, appealing, or of more than ordinary significance.
Much of this definition seems to divorce art from any specific set of precepts, especially since "aesthetic principles" can stem out of any individual's mindset and can maintain any level of contour as regards nature, civilization, rationality, or irrationality.
The idea that precepts are necessary to art pretty much extinguishes the possibilities of art and only allows it to function as a subserviant b|tch to a bunch of bull$hit ideals and morals touted by people with big egos and small imaginations.
It must suck to be you, considering you seem to have discovered the outer limits to what art is, can, and should be. If artistic discovery and innovation is pretty much over for you (since it isn't allowed to deviate from your precepts), it's no wonder you're trying to suck me into that horrible void by telling me how "wrong" I am to still nurture faith and curiosity. I'll continue to take a pass on the illustrious notion of knowing everything there is to know. Sounds like a boring scene.
