This book is similar in content to the author's first book, the popular "F & D Double Valve Bass Trombone," first published many years ago. The exercises in the original book were mainly designed for an instrument with a dependant (stacked) valve system.This new book focuses on the in-line bass trombone, pitched in standard Bb/F/Gb/D, with special focus on the second (Gb) valve. As in the original volume, this book uses a basic warmup and maintenance format to develop sound, intonation, articulation and, through the use of valve facility and etude exercises, develops valve skills and agility. 60 pages. -cdp
