Each Chopin Etude has a secret key, that once unlocked makes the Etude playable. What do you think the secrets are to the Etudes you have played? Please include your hand size and span, and whether you think this hindered or helped you master the Etude.
Given the amount of material written about the Chopin Etudes, the number of recorded performances, professional and amateur, and the wealth of tutorial videos, it does not seem likely that the "keys" to playing these Etudes are being kept secret.
