Agreed.. But way too hard.. I'm a very big fan of Alkan, since earlier this year I've learned a few studies.. I had spoken to this person named "comme", as in Comme le vent i guess.. Are you that person?
For 2006, I'm hopin to try the Grande Sonate (les 4 âges).
possibly
very hard, but very rewarding all the same
but also check out that guy jemboy's video of the LH 25/12
this really shows you how difficult it is, he blazes through horowitz transcriptions and the like....but the godowsky studies require a whole new and more compelx from of virtuosity, exreme left hand dexterity, and he is messy, slow, and required many edits to get it right, he may get it right in future...but this just shows you what seperates virtuosi...from supervirtuosi
and this can only come through hard work, over a long time, to develop the left hand
