Over 40, now having studied with over twenty professional singers and academic coaches, teaching and enjoying public performances in opera as well as several civic choral societies, I can only regret not having access to this material much earlier in my career. Recently I was introduced to Richard's master class and seminar and I knew immediately that I had to acquire this text. Unlike so many subjctive apporaches I have ran into elsewhere, there is little left to the imagination or to private interpretation when it comes to the pysiology and functionality of the voice as it is so well outlined in its pages. Regardless of the style of singing one might wish to pursue, every serious student/performer will gain infinite insight from following this comprehensive guide to perfecting a more internationaly accepted vocal technique. The sheer volume of difinitive information it contains constitutes the most exhaustive collection of practical examples, scientific research and systematic exercises that I have ever encountered. Now utilized as the basis of instruction at many universities, this lively publication is a must for every studio.
