Dieppo’s “Complete Method for the Slide or Valve Trombone” was an evolution and revolution in trombone pedagogy. This book was originally a joint effort between Berr & Dieppo, published in French (re-published at qPress as well). The original French book was quite short, but included all of the rudiments and beginner studies needed to teach someone up to an intermediate level.
After the publication of the original, Antoine Dieppo set out to augment the book to create a grand method. This revised and enlarged edition (which you see here) includes an appendix of nearly 100 pages of extra material, consisting of numerous studies and duets by Dieppo, Vobaron, Carnaud, and others. This work is universally used and is known as one of the most popular trumpet methods ever written.
Finally available as a digital edition, this book is one that you definitely want to carry everywhere. You can see some samples to the left, then grab an immediate PDF download above.
