"In preparing this book on Bass Trombone, I felt that the proper approach to the mastery of the instrument was an extensive study of each of the valve positions. The following exercises take each of the valve positions separarely, beginning with V1...Following the sixty valve studies are ten studies in the use of the pedal notes. These studies are extreme in the use of the pedals and are designed to give a full scope of their use...The final porition of the book is a scale study. "
