Choose Another Vocal Book
The vocal training and theory information in this book is not any different than some of the better vocal books available. There are some informative moments that can actually be used however, I and some of my students feel that the author spends too much effort on "knocking" other teachers and techniques, in addition to referencing to specific people that she prides their ability to herself, instead of just explaining the techniques, which we are looking for when we buy a book to learn. "Never buy a book by it's title".
