Query: Best instructional book for any singing style!

This is the best book on singing that I have ever read! The author, Jaime Vendera, gives you everything you need to improve the strength and quality of your voice. He explains the basic mechanics of the voice in an easy to understand way. Then, he provides simple, step-by-step exercises to help you reach your full singing potential, including warmup exercises, preventative maintenance, improving your ability to sing on pitch, etc. I particularly love the "pitch mapping" idea. There are also downloadable audio examples on jaime's site. If you are considering purchasing a book on singing, this is the one to get. Simply put: read this book, practice the exercises and follow the included principles, and you will improve!
