Hi,
While ago I found this amazing etudes. Unfortunately, they are not much famous and find some informations about them is almost impossible.
I showed this etudes to my teacher (she didn't know them), but she liked them and told, that I could start some of them before Chopin etudes.
My favourites are Op.2 nos.2, 3, 8, 10, 11, 12 (especialy 3,8,10).
Is there anybody who has played some of them? Do you have some advices?
How difficult are they compare to Chopin etudes?
