Uuuh, well I think of art as some sort of creation like a statue, painting, piece of music, etc. that tells the viewer of the art some sort of story, brings out some deep emotion from within them, 或者 it's a way for an artist to 显示 people how they are feeling inside. Like the picture below. I'm fascinated with it because it's powerful and has so much meaning. 你 can't help but to ask 问题 like what's happening? Who is the girl? Who is the armored man? Why is the crowd throwing things at them? And as 你 answer these 问题 to yourself 你 get a story out of the picture. That's what art is in my opinion.
Art: [noun] The expression 或者 application of human creative skill and imagination, typically in a visual form such as painting 或者 sculpture, producing works to be appreciated primarily for their beauty 或者 emotional power: ‘the art of the Renaissance’ ‘great art is concerned with moral imperfections’ ‘she studied art in Paris’
