At first sight, this is the more devastating reply I’ve ever read in this forum. But let’s put it in this way:
to come to full existence, a soul needs a living being to inhabit, not matter if a cat, a child, a beautiful women. It’s roughly the principle of the soul transmigration belief, or of the horror movies featuring zombies, craving for a transubstantiation into a real, flesh and bones individual.
Well, IMO this is true for every piece of music, too. It exists in its full, complete state only when executed by somebody. In this respect, every performance of a piece has a right of its own. No matter if played by gifted pianists or by a plain, inept amateur like me, the act itself of learning, playing a piece is a way to bring it to life, to make it real again.
And a world populated only by perfect human beings, like the one the craziest eugenics exponents dreamed of, would be a frightening nightmare….
