Title: Most Useful Vocal Book To Date
Review: I'm a professional singer, and Bob's book has helped me more than any other kind of previous vocal instruction. His vocal warmup technique has allowed me to improve my stamina, range, and pitch control. I use the book's CD every day to keep my voice in shape. Audiences and friends have noticed a very significant improvement in my singing. I'd like to personally thank Mr. Rose for improving my singing just in time to record my first CD!
