But the act of reading musical notation refreshes memory, and it is essential to maintaining an accurate performance of any piece. Inside the mind, pieces will fade away, even with regular practice, unless the student goes back to the score and plays it note for note without relying on memory. Practicing from memory alone will result in an inaccurate musical performance, and parents are asked to stop the student when memory-only practice becomes prolonged. Without reading reinforcement of memorization, students gradually make mistakes. Reading from the music itself positively reinforces accurate memorization, and only in this way can a piece be maintained for a prolonged period free from errors.
All musicians learn and re-learn music throughout the years.
The student is then too tired to accomplish much, if anything. If practice is to become part of daily life, then it must be given an assigned time in the daily schedule. The student's concentration when practicing will be better and more productive if the piano room is free from interruptions by other family members. If the student is to respect the daily practice time, so must the rest of the family. This respect is best expressed by allowing the student uninterrupted use of the room in which the piano resides during the scheduled practice time.
