Sound development is arguably the most important aspect of trombone pedagogy. Over time, most brass players arrive at a daily routine of exercises specifically focused on improving sound; however, certain exercises straying from traditional trombone performance—which are referred to as non-traditional in this document—have become or are becoming an important part of pedagogy. This study identifies these exercises, catalogs them into a pedagogical resource, and ascertains the prevalence of their use within the trombone community.

Delineated into four categories, this research explores the use of vocal techniques, external devices, buzzing in its various forms, and false tones/pitch bends. This document provides a detailed explanation and analysis of each technique discussed within the four categories. Analysis includes comparing the exercises to traditional tone studies and exploring their intended benefits to tone development. Trombone pedagogues continuously search for fresh ways to explain and demonstrate different aspects of playing to students; non-traditional techniques may potentially add a new branch of resources to the low brass pedagogical toolbox.
