Haydn Sonata in B minor, Hob. XVI: 32
Good to hear someone's digging it up this sonata, because, in my opinion, it is absolutely unfairly neglected.
Mendelssohn Variations serieuses in D minor, Op.54
Chopin Etude Op.10 No.7 in C major
This alone seems to be a lot indeed. The etude is the one with repeated notes (EG-EC FA-FD ...), right? How difficult is it?
Now my list for the summer:
Bach WTC P&F No. 15 in G major from Bk II and No. 10 in E minor from Bk I
Beethoven Sonata Op. 2 No. 3 in C major (remaining movements 3, 4)
Chopin Polonaise Op. 40 No. 2 in C minor
Chopin Etude Op. 25 No. 2 in F minor
And finally I have to get to know Scriabin. I haven't decided yet, so suggestions for a piece technically good for my level and not too complex musically are welcome.
