In the face of an increasingly competitive environment among trumpet players competing for professional performing jobs, college teaching positions, and entrance into music schools, trumpet players must obtain and sharpen skillsets that are outside the scope of the standard fundamental literature. Accordingly, this dissertation examines the existing fundamental literature, investigates extended and expanded playing techniques, and how best to practice them. The dissertation also looks at research showing that the best way for musicians to improve their technique is to place mental focus on the sound and the music while playing, rather than the individual muscle movements or physical aspects taking place. Therefore, the project details the combination of expanded fundamental techniques with common, singable melodies to create a method book that serves as a research-based approach to help trumpet players improve their playing quickly and sustainably.
