Is It Art?

There was a show that a famous pianist didn't play the piano for four minutes and thirty three seconds at his concert. It is a adverse crticism whether it is a piece of art or not. In my opinion, it is a piece of real art. First of all, some people insist that art have to have skills, but it doesn't have so it isn't real art. However do you know the 'throw painting'? We just spill and throw dyes to the sheet, but we call it real art. Therefore althought there was no techinic and no skill, it is a true art.
Socondly, unintended thing could be a art. Do you know Decalcomanie? We can creat unintended art through just sprinkling dyes on one side and foldilng paper into two leaves. We can't foresee the shape of the color. Additionally, after that concert, some poeple realized the real art. They actually said "Oh, It's so beautiful. Through this concert, I could realize the real art. Unintended and no skilled thing can be art. At first, I was really surprised. I didn't know what is happending. However after a little, I could perceive the real art. I am going to my house after getting lots of things."
At last, by no performance of pianist, we could listen the sound of audience. Most of people believe that it is purpose of pianist. Although audience went to the concert hall to listen sound of piano, pianist wanted to listen the sound of audience. He thought that can be a piece of real art.
In conclusion, I think the whow that a pianist's play is a real art. There are lots of reasons. First, art include no skilled thing. Secondly, art also include unintended thing. Thirdly, after that concert, some poeple realized the real art. The last, by no performance of pianist, we can listen the sound of audiences. Due to these reasons, I beilieve that it is a piece of real art.
