It is well known than Chopin didn't attach titles to the Etudes, and he may well have been opposed to others doing so, but I feel that it is our prerogative to do so if we find it at all useful. It useful to quickly refer to particular etudes. It is useful as a means to denote the character of the pieces in musical discussions as well. As a matter of fact, I wish more etudes had descriptive titles, so that it might suggest the mood or image that Chopin might have had in mind. For example, Opus 10, nos. 6, 8, 9, 10 could benefit from titles.
Incidentally, does anyone have ideas as to the "meaning" or musical character of 10/6? Since no technical issue is obvious, I must assume that the challenge is interpretive. I have often wondered if Wagner was influenced by this piece when he wrote Brunnhilde's scene "War es so smachlich" in Die Walkure. If so, it might suggest some interpretive ideas for us at this vantage point in musical history.
In the same way, I feel that Opus 25/7 which some have dubbed "The Cello" should be called the "Norma" instead because it definitely recalls the cello solo in the prelude to the last act of Norma. I don't believe I've ever seen this attested to in print, but the similarity is striking, and it may influence the way I work the piece, i.e., the Bel Canto influence in Chopin, when I get to it.
Titles are useful.
