You have lost me completely here. What would a loud off-beat note among three 2s be? An accent?
If that were so, then it would be two groups of threes with the accent on the triplet.
Obviously you've never heard the A flat waltz then. Because that's exactly what happens and that doesn't make it triplets there. It's an emphasised off-beat. An unassuming ear will never make the assumption that the left hand involves two off beat syncopations. In both cases, the simplest interpretation of an accent would be as an off-beat emphasis between two notes in a left hand group of 3- not as the start of a new triplet. Nobody would interpret the left in such a bizzarely complex way as to allow for listening to triplets unless trying to. The first abnormal aural event is on the fourth quaver. By then, the probability of 2s is already established by the simple coordination of left and right thus far. The ear would not have heard the 2nd left hand note as a weird off-beat syncopation inside triplets- unless it were either trying like crazy to do so or ignoring the left hand outright. So it's naturally heard as an off-beat accent against an established flow- not as a new triplet (unless you chose to try to listen that way).
If you feel there's a basis for an unassuming ear to detect the difference between the triplet of the etude and the non triplet syncopation of the waltz, you might like to clarify what differences in sound you would use for identification of that, compared to the etude. An unbiased ear doesn't magically know what is on the score. It simply listens for cues and forms a picture based on them. What is the difference in the aural cues that might inform it of the difference, please?
Strawman argument. All that is needed to show was that Cortot actually recommended the accents on the triplets. As I said to you, what you hear in his recording is subjectively yours. Someone else with a keener/different hearing will experience something else.
Sorry, but if you want a serious discussion you had better do a lot better. The fact that Cortot didn't cross out notes in Chopin's score and replace them with wrong ones could just as well be used for evidence that his recordings cannot contain wrong notes. Live in the real world- not in such a silly idealised one. Have you ever compared Schnabel's advice in his Beethoven sonatas edition with his recordings? This is a real non-starter. It's analagous to saying the emperor cannot be naked because his tailor already said that he dressed him in lovely clothing. The only pertinent issue is what the recording conveys to someone who is NOT assuming anything based on completely external information to the first hand evidence being discussed.
Also, as I said before, you should look up the meaning of strawman, if you're using it again. An argument I made to support my own case is most certainly not a strawman. A strawman would be putting words into YOUR mouth and arguing against something you never argued for. Whatever you're confusing the word with, it doesn't actually mean what you think.
We seem to be covering old ground here. Firstly what you are feeling has nothing whatsoever to do with what Chopin wrote. You might simply be playing/feeling it wrong. There are such things are wrong interpretation - even great pianists sometimes do that.
Which is exactly why I repeat my request for a "wrong" performance- so others and myself can compare it to Cortot and see for ourselves whether it sounds in any way different. Also, have you forgotten that you previously tried to argue that if Cortot said he did it one way then he couldn't have actually done it differently on a recording?
The question really is not about an idiosyncratic interpretation. There can/have be many over the 170+ years. It is about what the composer intended.
No. It's about whether it's objectively possible for anyone to know specifically what the composer notated or what the performer felt purely by listening to a recording. You can put your own goalposts wherever you like, but I'm not budging mine, sorry. That is what I am talking about- ie whether it's possible to make a listener perceive what Chopin wrote, based on playing alone and in a situation where they are not already expecting a cross rhythm via any external tip-off. I'm not believing a thing until someone demonstrates both that they are detecting an objective difference and that they can accurately identify whether a performer is feeling 2s or 3s on listening alone.
Again you have repeated the same fallacy - when you listen to anything, you are merely processing that against the your background of your own experiences and through your own sensory apparatus. We are not (generally) blessed with telepathy. Not yet anyway.
That claim is obsolete. I detailed the logical reason why a neutral brain would not automatically interpret something with a very simple explanation as being something with a very complex explanation- unless trying to. The converse does not follow. You don't have to try to hear a simple explanation to hear one- especially when complexity is not rammed down your throat via extreme accentuation. Either tear that argument to shreds or agree with it. To speak as if it was never made nor considered is not conducive to meaningful discussion.
Also, if you couple your above argument with mine about unbiased ears tending to go with simplicity over complexity- you'll realise exactly why nobody who isn't trying to actively hear a cross rhythm will perceive one. Because the combination of the brain's tendency to go for simpler explanations plus the issue of listening subjectively will mean that any complexity that is felt by the performer is EXTREMELY unlikely to reach anyone who isn't actively going out of their way to hear the piece that way.
