When I practice this Etude, I love to imagine that I'm playing a Bach Prelude from WTC. If I can play it with the same accuracy and evenness as a Bach Prelude (for instance F sharp minor part 1), I proceed to a faster tempo and add the "con fuoco".
thanks Hakki, costi Wofi..Eq, I would not dissapoint you. I will post a even/articulated version in about 2 weeks time. Just a start project.
