@Angry_Panda You must've been good! I've heard it takes a lot to be able to play a tuba skillfully, I don't have strong lungs to be able to play something like that. The repertoire list might go through changes if needed but currently it's Chopin Op.10 No.5(G-flat major), Op.25 No.9(B minor) and No.6 for Etudes, Ballade No. 2 in F major, Op. 38 and Nocturne in C-sharp minor, Op. Posth (Yes, I'm playing safe with the choices, lol) , and I'm not sure whether to include a prelude or not, it's not necessary but it might be viewed favorably, so I'm currently divided. 
What's on the repertoire list?
