Are you able to follow the score of your more difficult repertoire at tempo (once learned)? Do you find playing with the score at tempo to be easier or a distraction? Do you feel that occasional practice of a memorized piece with the score could aid in note-recall? How often do you look down when reading from the score (both for sight-reading, and for learned pieces)? Do you find it necessary to memorize difficult passages in music in order to look down so that you can play it (mostly for leaps, rather than fast/complex runs)?
