I think we can get confused with all sorts of terms when describing art. Provocation in art, what is it supposed to mean? Something that goes against the "norm" thus "provoking" approval/disapproval from observers? I doubt it is the main aim of all artists to provoke people, perhaps a handful are thinking this way, the majority are not. Most artists simply do their stuff for the Love of their art and if people find what they do is interesting that is just the cherry on top. Most of us do not care what other people think and simply do what we like despite other people opinions. We don't go, right, this is how everyone does it and accepts it being done, let me twist and change it to my own way. I guess many artists have some nagging force inside them to be unique, different, stand out, and try to do this in whatever way possible. They want to leave some type of contribution to music that lets them somehow achieve some kind of immortality with their artistic creation. Whatever method you use usually it is the Love for music which is more longer lasting that trying to provoke people.
It could be argued that some art provokes (or has in the past provoked) for the sake of so doing, whereas other art has done so without necessarily seeking that result as its sole or principal object; this fact reveals the issue to be rather more complex than you suggest in your opening salvo and is perhaps further complicated by an argument that conscious or subconscious artistic provocativeness need not necessarily be incompatible with a notion of artistic sacrosanctity.Best,Alistair
When playing Bach (J.S.Bach) or Beethoven, I always feel this provocative way of composing, and that's why I like to play this music. If it was not for this provocation, I would not play it.
Then I do not live very far away from Donaueschingen. I listened to many premiere performances on the radio (life!) in the sixties and seventies and I have clearly in my ears the screaming of the (partly angry and partly enthusiastic) audience at the end of each work. Nothing like the "holiness" which often is celebrated in "classical" concerts. So there obviously was a provocation and it was intended as a provocation.
