Certain key signatures aren't very common, especially ones with lots of sharps or flats, and doubly especially the enharmonic key signatures (a-flat minor for g-sharp minor, and so on). I'm wondering how many pieces (or at least movements) people can think of which use, as the foundational key signature, the four seven-accidental key signatures (a-flat minor, C-sharp Major, a-flat minor, and C-flat Major).
So far as I can tell, a-flat minor is the most common. The slow movement of Beethoven's Op. 26 piano sonata is so signifies, as are several pieces by Janacek, Dmitri Cuclin's 13th symphony, and so on. C-sharp Major was actually more common during the Baroque period than D-Flat Major, with the most famous example being the third Prelude and Fugue in The Well-Tempered Clavier; in modern times, D-Flat Major takes over, as in Prokofiev's seventh symphony, where the last movement should be in C-Sharp Major yet is notated in D-Flat. But C-Flat Major and a-sharp minor? Can anybody here think of such pieces? (remember, I'm asking about whole movements or entire pieces, not sections within movements).
