Bibliography: leaves 97-99. / This dissertation attempts to demonstrate the role the tongue plays in articulation in brass playing. It briefly examines oral anatomy, physiology and theories on motor learning, and describes the tongue's position in producing English speech sounds. It shows how these positions are used to teach different articulation techniques on the various brass instruments. Articulation styles and (tonguing) exercises, which could aid in the improvement of tongue articulation, are highlighted. It is hoped that these highlights will add insight for both present and future brass teachers.
