There are many different strategies that work for encouraging your child to practice and for instilling quality practice habits.
Have a scheduled practice time
One of the best ways to provide structure for your child’s practicing is to have a scheduled practice time. If a child knows that at a certain time of the day they are supposed to practice they will come to expect it and also know what is expected from him/her. How often should your child be practicing? Ideally, it is best for them to be practicing on a daily basis, or at the very least 5 days a week. This helps the student to become familiar with the material and also to be prepared for their next session with their piano instructor. It also allows for enough time throughout the week to reinforce the concepts that were taught by the instructor in the previous session.
