Now, how do you define the very idea of art?
This topic comes up here about once a month and it's really only got one correct answer. People who say "it has to move me/speak to me/be amazing/stir emotions/require technical skill" or something like that are obviously wrong, because otherwise then there would be no such thing as "bad art". Plenty of bad art does in fact exist, so there's obviously something extremely wrong with that kind of definition.
What defines art in reality is not the art itself, but the "frame" around the art. Without the frame, we don't know where the art begins and ends. Someone throwing a tomato against a wall is not creating art, he's just creating a splat on the wall. However, if that person then defines a frame around that splat (which may be a literal physical frame or just a spatial measurement) and says "within this frame lies my art" then it becomes art, because now we know where "the art" is and where "the rest of the world" is. The "frame" can also exist in time instead of/as well as space. Music is a good example of art that exists within a "time frame", which can be stopped, repeated or even left running (as a "work in progress"). Art objects can also exist in a more abstracted kind of way, such as a computer program that may be art, or an artistic performance piece that exists in a certain place/time. The frame doesn't have to be placed by the creator, either. Someone walking into a factory may hear all the different machines clanking in a particular rhythm and perceive the result as an art piece, however to the people working on the machines, they may not perceive this.
Of course, you, or someone else, may think that the tomato against the wall is
total shit, and that's fine. That doesn't make it "not art", what that makes it is (in the eyes of that person) "bad art". Anyone disagreeing with this is confusing the words "art" and "artistic", and the
real question they are answering is not "how do you define art" but "how do you define
something to be of artistic merit". Now that's a worthy question, but it's not the question that you're asking - however it's the question that over 90% of respondents to this thread will answer instead of the question that was put to them.
