Love how my kids are learning and really understanding music. They have been learning for a year and they know so much more than I learned in five years of lessons when I was a kid. And they are not hard to motivate to do their lessons most of the time. They love the lessons and are really learning to play, both reading music and playing by ear. I feel like it has been worth the investment. Sometimes we have to break up a lesson into a few days when they have to many theory pages on one day, but that is my only complaint and that is so minor compared to all the good.
