"As a teacher who begins nearly every lesson with a duet, I have profound appreciation for materials that help to solidify the musical bond of teacher and pupil. David Vining has gone one step further in Dueling Fundamentals by bolstering that one-on-one experience with well-crafted exercises in nearly every possible facet of essential trombone technique. I plan to use this book on a regular basis with my students. - Matthew T.

Dueling Fundamentals is a great way for students to sharpen their skills while keeping their ears open. The teacher can model everything from sound, rhythm, style, and pitch while the student plays along. Much more enjoyable and engaging than working on fundamentals by yourself! This will be a fun addition to applied lessons! - Natalie Mannix, DMA, Associate Professor of Trombone, University of North Texas
