That's the way, JohnMar78! With enough determination, you'll be able to do this piece. I'm determined to do it, too, but for different motives. I maintain that, for me anyway, opus 10 no. 4 is easier than several others: 25/8, 25/4, 10/5, 10/8, and 25/9. That opinion seems to have scandalized certain factions here, for whom it seems as though belief that 10/4 is hardest is something of an article of religion. If I can ever get anyone to help me put my recordings on the internet, all I need to do to prove them wrong is show that I can get through 10/4; I may not do it perfectly but I can do it, in contrast to not being able to do the others.
