Hah, lucky you, six hours a day for practice...
Since I never know how much schoolwork awaits me, I have a priority list I cycle through by 15-30-minute sessions. It looks roughly like this:
-
every day scales/arps (in sets of 3 keys: currently C - C sharp - D): roughly 15 mins, once a day only
- Chopin 10/4 (this one's usually a 30-minute session)
- Mozart K333, 1st mov (nearing completion, will be moving down the list shortly)
- Prokofiev sonata no. 3 (Yay!)
- Chopin 25/9
- Rachmaninoff 33/7
- Bach P&F c minor WTK I (basically done, playing with the fugue)
And, if there's extra time after going through this set at least three to four times, slowly starting to re-visit one small Dvorak piece.
And, if there's even more time (weekends...), improv/composition.

(Or more etudes.)
