To me, no matter the era, the style or the media, art is first in the creative and subjective mind of the art maker. Artists are the first definers of what art is. That goes for architects, composers, musicians, writers, playwrights, filmmakers and all the many and varied kinds of artists.
Beholders come much later, or perhaps not at all, with their own subjective views of what the artist has made. They respond to the work and decide if it fits into their definition or preconceived notions of what art is. If it doesn't, they have difficulty in recognizing the work as art.
Personal preference plays a gigantic role in that recognition, even for those who have extensive education and experience in seeing, hearing and experiencing artistic works.
For me, the more I see, hear and experience, the more I appreciate the work, but appreciation does not necessarily equal liking it.
For example, I cannot imagine a time when Baroque churches with "angels in the architecture spinning in infinity" to quote Paul Simon, will ever impress me in a positive way or at all, but I have to admit that they are works of art. In terms of travel, I'll skip the Baroque, no matter how famous it may be and choose the Romanesque or Gothic.
I'm a fan of contemporary art, but make a special trip to see a representation of Van Gogh's ear? Nope. But to see his paintings, which didn't begin to be appreciated until the year before he died? Absolutely, as many of them as I can, as often as I can.
