Many of Chopin's Etudes have been traditionally associated with particular words or images.
I once read a review in which the critic Adrian Jack wrote, "[Lugansky] runs up and down those treacherous chromatic scales in the second study of Opus 10 like a squirrel on a tree trunk."
Now I think of this work as being The Squirrel Etude. The left hand accompaniment reminds me of acorns popping and bouncing everywhere.
