Several years ago I took an independent study class at my high school. Every day I had 90 minutes of practice time and had to prepare something for a recital at the end of the term. On the very first day of this particular class my orchestra director, always full of music wisdom, shared a great nugget with us.
“I always practiced, but I never really knew how to practice until I had gotten to college. Had I known and used this before- I could have excelled so much earlier and faster!” Not only did he tell us to keep a journal, but also how to keep a one in such a way that will really show us improvement. “Its important to structure and plan out your practice session in order to be the most productive with your time.”
