This book was designed for private and group lessons. Most of the vocal instruction that we find these days is for students 16 years of age and older. This book is aimed at the very young because there is so very little written for them. I encourage the parents to have the children study voice, piano, violin, all at the same time when they're very young. Make it a time when you do something together. Singing is always good. In the car, put in the CD and buzz along with the piano. Little children usually do not have bad habits as far as singing. So we hope to establish good ones before bad ones appear.
