One of the most difficult etudes, wonderful because it has both left and right-hand workouts. Really clean and precise. What more is there to say!
Thanks.

But believe it or not, it is much more imprecise than you realize! If you have a wave program, load in the MP3, then lower the pitch 12 half steps (an octave), and this will do what we used to do with tape-recorders. You will find notes that are not together, that are later, that are early, some are hardly there (when they should be), etc.
I also used many takes, meaning that if I was working on a section and it "crashed", I did it again until I solved the problem. This is a way for me to learn, practice and try to form a cohesive performance all at the same time. If I could stop teaching, devote several hours a day to practicing only the piano, I would be ready to do this live in a FEW YEARS. And I should add that even that might not be possible because I'm pushing 60 REAL fast.

At any rate, I don't want people who are doing one-shot recordings to think that I can play this well on the spot, start to finish, no editing, no "splicing". I can do it with a few pieces that I teach a lot and "demo" a lot. But only a few.
Even the best players in the world are doing a LOT of splicing in studios these days, which is why we have an unrealistic idea of how accurate world-class pianists are.
That's why when you hear people play live, you hear all sorts of things go wrong, even with the best, but some REALLY cool things happen to.
