i don't have anything performance ready at the moment - but i could easily have about three pieces in one week. come back next week.
i think it's like cycling. once you know how to do it - you just do what it takes.
now, i am crying all because of this question. but, later today will forge ahead - despite the constant crank of 'why am i doing this?' i just am addicted to piano and like to play. i don't always practice for performance sake - but my goal is performance.
