The artist decides what art is.
Art traditionally evokes emotion and emotion evokes art, but emotion is not art and art is not emotion.
Art is what is around us, it is what makes us laugh and cry, it is the beauty that we try to emulate and the history we try to preserve.
Art comes from the creator, the one that sees the piece (traditionally), music, dance, performance, spoken word or paint.
Art is what you are. Each a canvas, each the brush, each the paint.
Look in the mirror and see the beauty that is truly fine art.
