What is Key?

All art has an overall function to evoke some kind of emotion (usually beauty). The misnomer, is mistaking the distinction between function and functionless. Art is supposed to be created for the purpose of being not because of its function, but the beauty of a piece ties into its function. So the matter of distinguishing between the two cancels themselves out and leaves one main principle. The making of such artwork had to be intentionally created for the purpose of being considered art. If it is not, then the matter of it being a function or functionless piece is irrelevant in my opinion.
