Wow - that's a very interesting blog. Thanks for putting this up, Alfonso. Looks like I've got some nice reading to do today.
And interesting about the tempo in Chopin's Etude 10/3. I never knew that about how the beginning is supposed to go much faster. Do you have a link to a recording of it like that?
No, I know of no interpretations like that. Perahia, who plays Op. 10-6 at the so often disregarded faster tempo Chopin indicated, plays Op. 10-3 at the usual slow tempo. So, we'll need to wait for Hough's take on the Etudes.
