Alright, I'm hunting for a good 20th century etude for auditions, preferably short, and would appreciate it if you guys could come up with some suggestions.
I'll list the ones I know of right off the bat:
Bartok 3 Etudes Op. 18
Debussy 12 Etudes
Kapustin Concert Etudes and Etudes in different intervals
Ligeti Etudes
Messiaen 4 Etudes of Rhythm
Morel 2 Etudes
Scriabin Etudes Op. 42; Op. 65
Sorabji 100 Transcendental Etudes
Stravinsky 4 Etudes
*I'm omitting stuff like Godowsky-Chopin and Rachmaninoff because I'm not really that interested in the romantic style, and would prefer something impressionistic, and/or mystical, i.e. Debussy and Scriabin, or at least tonal to a certain extent, i.e. Kapustin.
*Also, my maximum span is about a minor 9th, so I'd have severe difficulty playing many of the etudes I listed, i.e. Scriabin and Sorabji.
