I, myself, do not try to demonstrate to the listener any technical aspect. What I try to do, though, is to try to understand the source as best as possible. That's one of the things I find most interesting about being an interpreter.
I can think of all the technical stuff when I'm studying the piece, but ultimately when I play I just play and give my best to achieve musicality. The thing is that, having studied certain parameters in advance, I get to play the music in a different manner.
As regards counterpoint, taking the "loyalty to the source" factor out of discussion, I believe it's like film making. You may shoot long takes and let the viewer decide what to look at. Or you may do an extensive editing job to show the viewer what you want him to see. I rather not emphasize any voice and let my ears decide what to focus on.
Hehe, probably it's not matching the topic's title, but I think we're still on track. :D
Besides, I started the topic and I don't worry :P
Thanks for the thoughts.
