This book is a wealth of valuable information that will help you to become a successful voice teacher. Even if you are an experienced singer or teacher, John has some unique concepts that will increase your effectiveness. His Teaching Triangle and Teaching Toolkit provide an easy to understand troubleshooting method for diagnosing and fixing any vocal issue you or your students will face. That means quick, consistent results for your students and money in the bank for you!
John also makes the complex subject of formants and harmonics and their affect on singing very easy to understand. he has a knack for explaining things in simple terms that you can easily understand. Again, this translates directly to better solutions for your students and success for your teaching business. I could go on and on, but you get the idea. This is one of the most concise, yet value packed books on singing that I have read. If you want to become a more effective teacher I highly recommend this book.
