THE EFFECT OF A RESEARCHER COMPOSED MOUTHPIECE BUZZING ROUTINE ON THE INTONATION AND TONE QUALITY OF BEGINNING BAND BRASS STUDENTS A Dissertation Presented for the Doctor of Philosophy Degree The University of Mississippi Jason Beghtol May 2018 Copyright © 2017 by Jason Beghtol All rights reserved ABSTRACT The present study is an investigation of the effect of an author composed mouthpiece buzzing routine modeled by the teacher on beginning band brass students’ intonation and tone quality. The subjects (N = 43) were sixth grade beginning band brass students from a large band program in the northeast region of Mississippi. The experimental group (n = 27) buzzed a daily routine modeled by their instructor at the beginning of each class period. The control group (n = 16) received no treatment and proceeded through normal classroom activities. The duration of the instructional period was ten weeks. This study utilized a posttest only design. An independent-samples t-test was conducted to analyze the data. Taken as a whole, there were no statistically significant difference in the scores for treatment and control conditions. Results suggest the inclusion of a daily mouthpiece buzzing routine does not have a significant effect on beginning band brass students’ intonation or tone quality. Although not statistically significant, the measures lean toward improved intonation and tone quality. Results of the t-tests may have found no significant differences between means due to the wide ranges of variance in the two sets of scores. Keywords: intonation, tone quality, mouthpiece buzzing, embouchure, modeling ii DEDICATION First and foremost, this dissertation is dedicated to my family. To my wife Ginger and my two boys Jackson and Johnson who have been very supportive, patient, and loving throughout this entire process. Also, to my mom Vicki for supporting me, not only throughout this process but also throughout my entire musical journey from the first day I put a trombone together to the present. Secondly, this dissertation is dedicated to all of the phenomenal musical educators and influences that have inspired and guided me to this point and will continue to walk with me down my path. May you all continue to influence others for years to come with the love of music that you have shown to me. iii ACKNOWLEDGMENTS Thank you to my committee for insuring the quality of this research and for your guidance, as well as patience, of my experiences as a new researcher.
