I've been going to art museum
s with my Da since I was tiny because he is an artist and thinks I need to be exposed to art.
He has this theory that he brings up any time that I complain about a piece being incomprehensible.
He says that as an artist you are trying to express yourself. You are trying to communicate. Your goal is to translate your thoughts, problems, desires, whatever into a medium.
Ideally you want other people to understand this translation.
If your audience doesn't understand what you are saying then you are just babbling to yourself; and while you may feel refreshed or relieved by talking to yourself, you aren't being a very good communicator.
This doesn't mean that you are not making art, though it may mean that you are not making good art, because there will always be someone who will understand (or think they understand) what you are talking about.
But still it is important to communicate with your audience: If you aren't communicating what are you doing it for? Your craft becomes nothing but mental masturbation and THAT is definitely not good art.
