The first method book from Chris Sharpe, Bass Trombone Double Valve Technique provides a progressive approach to learning and developing valve technique on the modern independent-valve bass trombone with valves tuned to F and G-flat. The book contains exercises with short two or three note patterns, builds up through scales and arpeggios, and culminates with an etude in every major key. This book is ideal for high school and college bass trombone students looking for a detailed exploration of various uses for the valves.
