It certainly is a challenge, to perform opus 25 no. 12. I think it's rather unfortunate that this piece came to be known as the "Ocean Etude"; the atmosphere of it seems much more funereal than maritime, especially since the measures 4 to 7 have, in the base, four notes that coincide with the melody of the Dies Irae. I doubt if that's just an accident that Chopin didn't intend. Yet on the other hand, the instructions are "allegro molto, con fuoco", and the text of the music is replete with fortes and fortissimi -- even fortississimi. I would hope that performances would not have to be so loud that the beauty of the harmonies would be washed out like the colors of a flower garden under the noonday sun. It really is a profoundly sad piece; when a B-flat sounds simultaneously with an F-minor chord, it is as if a man who was giving a eulogy for the deceased had his voice break into a sob. In fact, for many years I abstained from doing this piece; the sadness of it seemed positively morbid.
