I'll take this conversation offline.
There are waaay too many red herrings on unrelated topics (the conductor feels the music on the keyboard?
the different listening experiences equate to musicality?)
I don't care that the music is different if you leave out notes (wow, you just added nothing to the conversation). [...]
Listen to Argerich's famous Rach 3 performance and then come back to me.
I will soon post some edited pages of the Rach 3 piano score, with notes which I personally think do not hugely contribute to the music removed.
