The Purpose of Art

From Paul O'Neill of Trans-Siberian Orchestra:

The purpose of art is to create an emotional response in the person that is exposed to that art. And there are three categories of art; bad art, good art and great art.

Bad art will elicit no emotional response in the person that is exposed to it, i.e.; a song you hear in an elevator and it does nothing to you, a picture on a wall that gives you the same emotional response as if the wall had been blank, a movie that chews up time.

Good art will make you feel an emotion that you have felt before; you see a picture of a forest and you remember the last time you went fishing with your dad, you hear a song about love and you remember the last time you were in love.

Great art will make you feel an emotion you have never felt before; seeing the pieta, the world famous sculpture by Michelangelo, can cause someone to feel the pain of losing a child even if they've never had one. And when you're trying for these emotions the easiest one to trigger is anger.

Anyone can do it. Go into the street, throw a rock at someone, you will make them angry. The emotions of love, empathy and laughter are much harder to trigger, but since they operate on a deeper level, they bring a much greater reward.
