I'll try and get as far as possible on the way to mastering all Chopin etudes, while also re-learning his Ballades no. 1 and 3 (haven't played them in 8 years and haven't played piano in 7 of those years either) and Scherzo no. 2, and Schubert's Sonatas D894 and D 960, and probably a whole myriad of minatures and easier works.
Maintaining and improving my current repertoire (Chopin's Barcarolle, 3 Ecosaisses, the Fantaisie-Impromptu, and a couple of Mazurkas, plus Beethoven Sonata no. 8, Schubert's op. 90 no.4 Impromptu and a piano transcription of Saint-Saëns' 'Le Cygne') is in the planning as well.
On the side, even though I am an amateur pianist, I'll take on my first pupil, a friend of mine who finishes university in February and then will finally have time to start practicing again seriously. She already knows the basics of piano playing and has had lessons for 3 years when she was in secondary school, so I am mainly there to inspire her, help her choose new stuff to work on, and give her feedback. Anyhow, it's goin to be an interesting and hopefully fruitful 2013
