So I was thinking about applying for the Ettlingen international piano competition in 2018. The repertoire requirements are the following: One movement from a Beethoven, Haydn or Mozart sonata, one etude by Chopin Or Liszt and one ore more pieces of free choice. For the etude I am thinking something like op. 25 no. 6 by Chopin, and for the pieces of free choice I want to play sonata 4 by Scriabin and Feux d'artifice by Debussy. Those pieces take about 15 minutes to play, and the playtime is 20-25 minutes. I thought, since the Debussy will show a lot of colours, and Chopin and Scriabin are both very poetic, I want to play a more humorous sonata movement, but I don't want to play Mozart or Haydn. So what I am wondering is, which Beethoven sonata do you think would work the best with the rest of the pieces? I am thinking about either op 31 no 1 or 31 no 3, since they are some of the most humorous and happy Beethoven sonatas, but I am not sure which sonata movement to choose. What do you think?
