I have all my pieces listed in a monthly spreadsheet. I check them off and try to play them once a week if possible.Without this method, I have found that I've neglected pieces or even forgot about them altogether. If I don't have a lot of time, I'll just work on keeping up/improving the sticking points in any of the pieces. I can get in a lot of quality practice then and the next time I play the entire piece, I see an improvement overall. Cheers,allthumbs
