Acoustic Strategies that Improve Vocal Fold Behavior

This presentation will explain how laryngeal and acoustic registers interact with and influence each other and why our perception of vocal registers is due to acoustic relationships more than to changes of laryngeal mechanism. Understanding these relationships and the resultant migrations of timbre and sensation is very helpful in achieving the smooth transition of mix across range. I will also revisit the chiaroscuro whisper training device and workshop its use in improving resonance turning skill.  Q&A follows. 

Application of Acoustic Vocal Pedagogy

This masterclass will explore strategic applications of acoustic pedagogy to vocal styles that primarily utilize a clean (non-noisy) signal.  Q&A follows.  

Kenneth Bozeman, BM, MM, Professor Emeritus of Music, taught at Lawrence University for 42 years where he chaired the voice department and from which he received two awards for excellence in teaching. He holds performance degrees from Baylor University and the University of Arizona and studied at the Conservatory of Music in Munich. He was awarded the Van Lawrence Fellowship by the Voice Foundation in 1994, is the chair of the editorial board of the Journal of Singing and was inducted into the American Academy of Teachers of Singing in 2019. His writings on acoustic voice pedagogy include the books, Practical Vocal Acoustics: 

Pedagogic Applications for Teachers and Singers, and Kinesthetic Voice Pedagogy 2: Motivating Acoustic Efficiency, now in a second edition. Bozeman’s students have sung with Houston Grand, Boston Lyric, Deutsche Oper Berlin, Dresden Opera, San Francisco, New York City, the Metropolitan, Chicago Lyric, and Santa Fe Opera. https://faculty.lawrence.edu/bozemank/

Aimee Geddes has been teaching for nearly two decades and got her start as a college student in 2003 when she was studying Musical Theatre at Weber State University in Utah, where she actually earned her BA in Communication. She found the mechanics of the voice and vocal technique to be fascinating and wanted to share with others the joy that she felt when conquering a new vocal “problem.” Since then she has become a sought after audition coach and keeps her studio at capacity on a consistent basis. IVTOM has played a huge role in her growth as a teacher and business owner. Aimee started out as a chest puller/flipper and didn’t really find her “head voice” until college and even then it was iffy. Teaching mix (and singing along to every Kristin Chenoweth song available at the time) helped her develop her own young–adolescent–voice alongside her students.

She grew up performing various roles on stage from Wendy in Peter Pan to Anita in West Side Story–in the same year. Since, she has helped countless students land leading roles in productions in their communities and schools. She has done print modeling and online tutorial videos for various companies and is a busy wife and mother of 4 children (all of them human). She loves reading a good romance novel while climbing stairs at the gym.  Aimee became a member of the IVTOM Board in 2012 and has been an Accredited Teacher throughout her involvement with IVTOM. She became an IVTOM Mentor in 2019.

Formantology: Adding Analysis to Intuition When It Comes To Vowels for Singing

Coined by Scott McCoy in his article of the same name in 2013, “formantology” is an exploration of the ways the resonances of the vocal tract move and change between vowels and how they interact with harmonics to create formants. This presentation will focus on the basics of acoustic phonetics and then go further to explore the similarities and differences between the resonance strategies of children and adults and the ways registration and vocal style impact vowel choices.

Kelley Hijleh is a VoceVista practitioner, educator and consultant, and the Associate Director of the Singing Voice Science Workshop. She was mentored in vocal acoustics by Dr. Donald Miller (1933-2020) for 15 years, and has been an invited presenter and discussant on Voce Vista and vocal acoustics at The Voice Study Centre, SUNY-Fredonia, Syracuse University, Illinois State University, at the Voice Pedagogy Summit II in Los Angeles, and with Richard Lissemore at the NATS Eastern Regional Conference. Her article Realizing the Benefits of SOVTEs: A Reflection on the Research co-written with Cory Pinto appeared in the Journal of Singing in 2020. Ms. Hijleh holds a Bachelor of Music degree and a Graduate Performance Diploma from the Peabody Institute of the Johns Hopkins University in voice performance. She has appeared as a soloist with the Rochester Philharmonic, the Buffalo Philharmonic, and the Ashland Symphony.

The Imposter Syndrome, Who Me?

Imagine for a moment that somewhere inside of your head is a cast full of all types of “characters.” Some are supportive of you, the Performer, while others seem to have their own agenda. Among these characters is a Director that is managing the show. There is a Performer that wants to be free to shine in the spotlight. There is an Imposter that wants to usurp the Director and steal the spotlight from the Performer. We will be learning specific tools to befriend the Imposter, empower the Director and liberate Performer.  Dr. Jon will be joined by songwriter Kristen J. Lloyd who will share her story and perform her original, My Brave.

The Leggiero Tenor Voice 

The Leggiero Tenor voice is one of the most complex, and frequently misdiagnosed voices of the entire human voice spectrum. In this masterclass, observers and participants will hear how Jeff discovered he was a leggiero, and he will teach participants how to recognize a true leggiero tenor voice, while offering exercises and concepts that teachers can add to their Mix toolbox to train this specialized voice type, and maximize it’s potential.   Jeff will vocalize and coach 3 singers who are, or may be, leggiero tenors for the class. Q&A follows.

He has coached some of the top performers on Broadway including Constantine Rousouli, Jelani Remi, and Contemporary Christian recording artists such as David Phelps. His co-masterclass with Mr. Phelps was a life changing experience. Jeff is passionate about teaching voice while maintaining a busy performing schedule with the 80’s cover band Fast Forward 80’s where he gets to use his leggiero tenor voice for the music of Journey and more.

A Practical Approach for the Voice Coach as First Responder.

Revisiting a critical subject: What do I hear?  What is my next step? You’ll hear audio recordings of singers who present in studio with previously undiagnosed pathologies and/or technical voice issues, decide what YOUR next step would be, and then hear/see evidence of the actual diagnosis along with recommendations for treatment/rehabilitation/habilitation.

The Nose, Singer’s Friend or Foe?

Many singing teachers agree that a narrow passage leading to the nose can be beneficial to the timbre of the voice, while many others have the opposite opinion. Three experiments will be described, the purpose of which was to show how such a passage affects the sound produced. The results indicate that the paranasal cavities absorb sound but also that the nose can enhance the high frequency components of vowel spectra without causing the voice to sound nasalized. Q&A follows.
