Man, just practiced 2 hours without being aware of the time! I played a few lines of the piece until I hit a less than beautiful sound, then played those bars until they sounded clear and clean. I moved to the next few lines and did the same thing. I also did some trill exercises to improve the sound of trills because there are a few in the piece. I also played scales in 2nd position because that helps me develop muscle memory in my fingers to play in tune. I had to stop because the chin rest started to hurt my neck and gave me one of those hickey looking things.
