What makes good art?

Good art is something thats incredibly hard to define. One one hand art that is appealing can be linked to math and something intricate about the human body. Patterns such as the Golden Rectangle, phi, the rule of thirds and others seem to be naturally appealing to humans. Something about our DNA makes us naturally drawn to such patterns. An artist that can identify and capture these tendencies is able to create art that is universally pleasurable. Paintings like Dali's or the Mona Lisa as well as Classical Architecture capture these mathematical codes. But on the other hand, good art is one that portrays a certain mood or feeling to the viewer. This aspect is more personal, dealing with one's own connection to the art. Perhaps the photograph portrays a sense of adventure to a young teenage boy, or a different painting portrays class to an aspiring fashion worker. Either way, art that expresses the mood or desire of the viewer can be much more appealing to the onlooker. Some pieces of art may have broader messages that lead them to become more popular. Good art is by no means something simple to explain, however one can reason that a mixture of innate human tendencies and personal connections combine to shape the popularity of the piece.
