All this "inspiring love" or "artistic originality" cannot be quantified so it shouldn't be taken into consideration. Playing the piano is first and foremost an athletic endeavor of the body and intellect.
for instance, i don't like hearing an extremely fast tempo with a 'grave' tempo that is dead in the water. you know - like some people take the last beethoven sonatas. i mean he wasn't dead yet.
This, in actual fact, is a really good topic, and it is surely deserving of greater recognition.
