Okay, so here's my update so far:
List A: Bach, Toccata and fugue in e minor, BWV 914
List B: Beethoven, Moonlight Sonata, c sharp minor
List C: Chopin, Nocturne in c sharp minor, op. 27, no. 1
List D: Rachmaninoff, Prelude in g minor, (op. 23, no.5 I think)
List E: no clue
Concert Etude: no clue
I'm thinking for my last two, that they should probably be in Major keys to balance out the minor(ness) of everything else. OH NO! I just noticed B and C are in the same key. Is that really bad when you're putting together an exam program? And my other question was, if I'm doing a major Chopin piece already, a Chopin etude would probably be too much of one composer for this type of exam, no?
