Assume that your child went to regular school and every day the teacher asks you to help him a bit with his homework for quick progress. For you it will not make much effort because you went to school too in your childhood. So if your talented child has started taking music lessons, isn’t there a need for music education for parents too?
I’ve been teaching at music school for many years, and I am always apprehensive of parents who bring their children to music school but have no intention to understand anything about music education themselves.
