I believe art have always being about the concentration, the attention to you senses to eliminate thoughts and without thoughts become able to experience atemporarily. Eliminating the space between you and the work of art and experience to be part of it or it to be part of you. And I have the feeling that many peaple have never experienced it.
Today, with so many distraction, on-line interaction, online information and games, specially mobile games, people are used to do many things at same time and the attention span becomes very short.
It looks like the best way to get attention from people with short attention span is with distraction. It means that many people don't appreciate art as people used to do in the past. Music becomes just a distraction or an ambient sound. Even when people are in the streets listening their MP3 during shopping, cycling or whatever they do, music becomes something to distract people from their routines. Most don't sit down to listen music, they listen music while they do something else, specially while they are in the internet.
The same we can say about visual art. Painting and photographs used to be about the silence. Today, many people look at paintings and photographs in a hurry. It is not about the appreciation any more but about the distraction, so photographers follow the screen language, of fast action, movements and short information to better become a effective distraction.
With all this change can we say that art, in most cases and for most people, are no longer art but entertainment?
