...anyone who thinks that there can be cheating in piano/instrument performance is seriously misguided....Simplifying isn't cheating
Thanks for sharing your opinion. One nice thing about this forum is that it gives people of different musical ability, technical proficiency, and level of musical education a chance to interact.
Here we have a slippery slope. A composer writes something. Someone else doesn't have the technical ability to play it, so that person intentionally changes it. Is it still the same piece? If you say 'yes', then at what point does a simplification cross a line? After changing two notes? Twenty notes? All the notes?
To give a concrete example, consider the Chopin Etude in g-sharp minor, Op 25, no 6, a piece that I find very difficult and therefore have never programmed. What if, while practicing it, I decide to simply omit all the notes I can't play cleanly, and then I program the piece that way -- without acknowledging my simplification. Would that be honest?
By your logic ("simplifying isn't cheating"), it would be OK.
Or let me try an analogy involving language. Let's say there is to be a poetry reading of Paul McCann's "Dancing Dolphins", but the narrator has a technical limitation -- a slight lisp. So instead of reciting "Those tidal thoroughbreds that tango through the turquoise tide..." as written, the narrator goes through the passage and simply deletes all the words he can't pronounce clearly. Again, by your logic, that would be OK.
Sorry, but I beg to differ.
Now, returning to the Schubert passage in question.
I don't know what you're talking about. It sounded fine to me.
Well, then, it's apparent that you don't know the piece well. If one has the LH technique to play this passage cleanly in tempo
as written, it sounds one way. Try listening to Maurizio Pollini's recording.
If one eliminates half of the LH notes from the passage, as Brendel did, it sounds another way... and it's not the way Schubert intended it to sound.
Keep practicing and studying. Maybe someday you'll be able to hear -- and comprehend -- the difference.
