Hello!

I want to help you with your repertoire.
1.Etudes: Dependes on your technique.
Czerny op.740- one etude from this set (they are all difficult and have technical problems often found in complex musical works).
Chopin- one of both sets.
Liszt-one transcendental etude or one etude in exercises op.1.
2. Sonatas.
Beethoven (all sonatas excepting op.2 no.1, op.49 and op.79)
Mozart ( all sonatas excepting k 545)
Haydn (hob 16 no.1-17)
3. A piece by Bach
A prelude and fugue- 3 voices.
The inventions are too easy for a conservatory audition.
4. A romantism piece
S. Rachmaninoff- op.3

(It is hard to say but this set is too easy), op.23 and op.32 Preludes (2 preludes), Corelli Variations.
Chopin- Ballades, Scherzos, Rondos, Impromptus, Polonaises.
Other pieces by Mendelssohn, Schumann,Schubert,Alkan, Albeniz,Grieg, Alkan, Scriabin, Brahms, Liszt, Tchaikovsky, Mussorgsky and other.
5.Modernist composers like Ravel, Debussy, Bartok, Stravinsky,Prokofiev and other.
6.A concerto by Haydn, Mozart, Bach, Beethoven, Tchaikovsky, Ravel, Scriabin, Rachmaninoff, Chopin, Schumann, Grieg, Brahms, Prokofiev.

(if you don t play a sonata and you want something more challenging).
Hope this will help you.
