My students often ask me this question: "Hey mister, art, what is it?" or watching a painting of Picasso: "It is selling this thing?" These questions bother me deeply, because the answer is already contained in the question: the art is useless and Picasso did anything since my little brother 5 years could do the same thing. The worst is that these prejudices are shared by many adults. Sad to say but we live in an age where what is not selling, which has no direct practical interest, no practical use, has no value. However, such logic becomes too easy, in fact, if art did not serve absolutely to nothing, why is it also present in our society? And besides, in all societies in various forms. So what is art? What it occupies so important place? What can he bring?
What is it art? That is to say, what are music, poetry, painting, film, sculpture or literature, theater, architecture?
Let me give just one example that impressed me:
I remember this amazing video where we see Isaac Stern, in a concert in Jerusalem during the Gulf War, bareheaded, playing before a crowd of spectators wearing gas masks because of an alert of fire missile.
He said in an interview: "I played a Mozart concerto with the Israel Philharmonic conducted by Zubin Mehta, when suddenly he came to me:" Isaac, there is a missile attack, we must stop the concert "The orchestra was then removed and I felt the nervousness was beginning to gain the public. I then took my violin and I played the 'Partita in D minor for solo violin' of Bach. It was funny to see all these people in the room with their gas masks ... Slowly, they relaxed ... I just wanted to feel useful and defy the fury of destruction through music ... "
Blaise Pascal wrote: "Man is neither angel nor beast."
That day, February 23, 1991, against bestiality, horror and destruction, the voice of an angel was heard,  a Man rose to the rank, the dignity of a God.
Thanks, Mister Stern.
So the art, it will not really anything?
