Aaron Harris was a trombonist who was also a prolific author of methods and etude books. His studies for all brass instruments are hidden gems in the catalogue, and anyone who knows them recommends them vigorously.
Harris' Trombone Method comes from the Aaron Harris Trombone Series, which also includes his books “Scales & Etudes”, and “44 Etudes”.
I have included a few different pages in the samples to the left so you can get an idea of the layout and difficulty. This book is in two parts, and has traditionally been sold separately. Please click through the samples, then click above to grab an immediate PDF download.
