A Piperism

Is there a way that performance art is not the most unique form of art?

I do believe that performance is the most unique variety/medium of art. This is perhaps/probably because of her philosophical wherewithall when it comes to art; if another equally as intelligent critic had argued that prose was the most unique form, I might agree with them. But! For the time being...

The thing that makes performance art the most unique in my opinion is not the spatiotemporality. This, in my opinion, is rather knitpicky - of course the event happened in a certain space in an unreproducible time. That is the nature of the world, that the same thing cannot happen twice. The most distinctive feature about performance art is the emotion on the parts of the performers. No two people will put the same energy/hutzpah/moxie/emotion into a role, and so the role is bound to be slightly different.

If an actor takes stage notes, intricate emotional ones, and another actor receives those and uses them to more accurately recreate the performance, has (s)he done a better job with the role?
