Book excerpt: Popular for more than two decades among college voice teachers and their students, this outstanding, authoritative vocal pedagogy text is an invaluable manual. It thoroughly examines the vocal problems prospective voice teachers will encounter daily in the teaching studio and choral rehearsal. The author’s approach is a unique one, based in large part on diagnostic procedures similar to those used by doctors. As each vocal fault is presented, its identifying characteristics or symptoms are stated, its possible causes are discussed, and corrective procedures are suggested. An especially valuable feature is the book’s accompanying audio files (available here for download) that contains 14 male and female voice samples of the various vocal faults discussed in the text, enabling students to better identify basic characteristic sounds associated with each fault. Current and prospective choir directors and voice teachers who need help in improving the vocal sounds of choir members or students will find this practical guide-book to be an ever-present help in time of trouble.
