We've established the fact that B's piano had this characteristic - the discussion now is just how to effectively half-pedal on the modern piano to achieve a satisfactory result--or is it even possible without creating a totally different effect than intended. Or, as in many arguments regarding baroque interpretation, would the composer have written differently if in possession of our modern grand.
I find these discussions interesting and enlightening, and it's fun to attempt this at the piano by myself; but, while an Andres Schiff might get away with his somewhat speedier, sustained interpretation in public because of his reputation, I'm not sure I could. How many of you would risk playing it this way for a jury? Like I said earlier, unless handled carefully, it could sound to many like sh....t.
