Hi, so I have a competition coming up soon that needs two contrasting pieces for solo piano from two different eras of Western classical music including Baroque, Classical, Romantic, and Twentieth Century. It also must contain up to 15 mins max. I was thinking of playing Chopin- Sonata in B flat minor, Op. 35 mov. 1 but i'm having trouble coming up with something that'll be able to contrast it, so any suggestions would be great. Im also open to any other suggestions or opinions on whether I should play the Chopin or not. Thanks!
