Subtitled "An Extension of Standard Trombone Techniques and an Introduction to Some New Ones," explains the book nicely. Oriented towards the jazz and commercial player, this book is a set of 47 one-page "units," each with a few short exercises on each concept. For tenor or bass trombone. Unlike many technique books, this book does not just present a series of large etudes with many technical problems. Instead, each unit focuses on a specific trombonistic technical issues (lip-break articulations, glissando, chord progressions, etc). Contains a nice section on "doodle" tonguing. The CD contains recorded examples by Watrous (tenor) and Raph (bass) of most of the exercises. The cover photo is of a very young Bill Watrous. -cdp
