Recitals are a great opportunity for your child to really get to know a piece of their choosing, and work towards making it performance ready. They learn about setting goals, managing their time and all aspects of performance; like stage etiquette and controlling their nerves. Your child also knows you value their music when you make time to encourage their practice and attend the performance!
"Music performance teaches young people to conquer fear and take risks. A little anxiety is a good thing and something that will occur often in life. Dealing with it early and often makes it less of a problem later. Risk-taking is essential if a child is to fully develop his or her potential"
