An Ultrasonographic Observation of Saxophonists’ Tongue Positions While Producing Front F Pitch Bends by Ryan C. Lemoine A Research Paper Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Musical Arts Approved April 2016 by the Graduate Supervisory Committee: Joshua Gardner, Co-Chair Christopher Creviston, Co-Chair Sabine Feisst Robert Spring ARIZONA STATE UNIVERSITY May 2016 ©2016 Ryan C. Lemoine All Rights Reserved ABSTRACT Voicing, as it pertains to saxophone pedagogy, presents certain obstacles to both teachers and students simply because we cannot visually assess the internal mechanics of the vocal tract. The teacher is then left to instruct based on subjective “feel” which can lead to conflicting instruction, and in some cases, misinformation. In an effort to expand the understanding and pedagogical resources available, ten subjects—comprised of graduate-level and professional-level saxophonists— performed varied pitch bend tasks while their tongue motion was imaged ultrasonographically and recorded. Tongue range of motion was measured from midsagittal tongue contours extracted from the ultrasound data using a superimposed polar grid. The results indicate variations in how saxophonists shape their tongues in order to produce pitch bends from F6. i ACKNOWLEDGMENTS I would like to acknowledge and thank the saxophonist who volunteered their time to make this study possible. Also a special thanks to the members of my doctoral committee: Joshua Gardner, Christopher Creviston, Sabine Feisst, and Robert Spring. They have all been sources of encouragement and inspiration, not only during these final stages of my degree process, but for the duration of my studies at Arizona State University. I truly appreciate and would like to thank Dr. Christopher Creviston for his guidance and insight in helping to mold me into a better musician. A huge thanks goes to Dr. Joshua Gardner for agreeing to help a saxophonist complete a science project and providing meticulous edits! I also want to sincerely thank my wife Romy, for her help editing and constant support during this project. ii TABLE OF CONTENTS Page LIST OF TABLES ....................................................................................................... v LIST OF FIGURES ..................................................................................................... vi CHAPTER 1.
