The authors of numerous singing manuals, Caldwell and Wall (voice, Texas Woman's Univ.) present a remarkable resource for voice teachers, bringing together and building on much of the current and historical theory of vocal technique and training. Singers, coaches, and choir directors will also find much of value if they are not daunted by the quantity of information presented. Each volume includes many vocal exercises and interesting case studies. The first two volumes will be especially useful for beginning teachers: in a field rife with jargon and elusive imagery, the authors share suggestions to improve communication with students. In addition, the sections on teaching anatomy, acoustics, and the science of sound are very detailed. Volume 1, Beginning the Process, investigates teaching and learning at various levels. Volume 2, Mastering the Fundamentals, covers breath management, muscle awareness, and the use of resonators. Volume 3, Advancing the Technique, offers exercises and information of value to the advanced student. There is also an excellent section on teaching belt tone for musical theater students. Volume 4, Becoming an Artist, addresses important areas for aspiring professionals, including learning a score, preparing texts, and communicating with an audience. Volume 5, Managing Vocal Health, gives advice on when to send students to a physician and what to expect from a physical exam. Medical procedures for treating various vocal disorders are also discussed. A separate index volume (not seen) will accompany the set. Vocal study is a lifelong process as the "instrument" matures and then ages, and teachers and students work at a wide range of abilities something this work's multilevel approach effectively addresses. There are many more concise (and less expensive) books on vocal technique available, but nothing as comprehensive or as potentially rewarding for the serious voice teacher. Highly recommended for academic libraries and large music collections. [This can be purchased as a set or by volume. Ed.] Kate McCaffrey, Onondaga Cty.
