The Diagnosis and Correction of Vocal Faults by James C McKinney (1997, Paperback)

This book is a perfect suppliment in a vocal pedagogy course added to your current text! It explains the vocal process and the importances of breathing in a different way from, per say, the more common book entitled, "The Basics of Vocal Pedagogy" by Ware. Ware's book is my favorite, but this book is my second favorite of you are looking for extra reading material on this subject, and to better understand how the voice operates.
