'Online Courses in Acoustic Vocal Pedagogy' with Kenneth Bozeman - 2 days, starting 9th May 2020 - SOLD OUT

Course Details

Due to such a high interest in the April dates, we are hosting another two Acoustic courses online via Zoom with Kenneth Bozeman. This online platform enables interaction within an online classroom and the numbers will be restricted to 20 participants to enable interaction. The introductory course is designed for those seeking a basic introduction to acoustics and the second advanced course is aimed at those with a secure knowledge who wish to gain a deeper understanding. You may take both courses together but this is not a requirement.

Introductory Course

  • Introduction: Overview and Sources of Acoustic Pedagogy
  • Psychoacoustics:  Relevant aspects of how humans perceive sound
  • Absolute Spectral Tone Color (ASTC) (from Ian Howell)
  • Auditory Roughness (From Ian Howell)
  • The Voice Source
  • Respiration and Pre-phonatory Tuning
  • Modes of Onset
  • The Voice Source Signal
  • Modes of Phonation
  • Requirements of Healthy Function
  • The Vocal Tract Filter
  • Resonances and Formants
  • Roles Played by Formants
  • Vowel Formation
  • The Implications of ASTC on Vowel Formation and Timbral Balance

Advanced Course

  • Acoustic Registration and Its Relationship to Laryngeal Registration
  • Vowel Migration & Vowel Modification
  • Other Somatosensory Migrations
  • Implications & Applications for Treble & Non-Treble Voices (Passaggi; Range Extension)
  • Implications for Belt-Based Genres
  • Studio Tools and Strategies
  • Use of spectrography and voice synthesis

Introductory Course

After explaining the sources from which this pedagogic approach has been drawn, it will proceed to introduce basic aspects of how the human brain perceives and processes sounds (Howell). It will then elaborate various aspects of the voice source (the pressure waveform arising from how glottal behaviour and aerodynamic factors modulate airflow and pressure into an acoustic signal). This will be followed by an explanation of how the vocal tract filters the sound signal introduced by the voice source, and how it feeds acoustic energy back to the source affecting its behaviour. Finally, we will explore the implications of absolute spectral tone colour on vowel formation and timbral balance.

Advanced Course

The advanced course will begin with a thorough elaboration of acoustic registration, and its relationship to laryngeal registration.  We will continue to explore the implications of spectral tone color on passive vowel migration and active vowel modification(Howell, Bozeman), as well as other sensory migrations across range (Ballantyne, Bozeman).  This will be followed by specific application of acoustic registration and timbral migrations to treble and non-treble passaggi and range extension.  Implications of vocal acoustics for belt-based genres will be offered.  All acoustic transitions and migrations will be demonstrated with recorded singer samples, spectrography, and voice synthesis.


Kenneth Bozeman, BM, MM, Professor Emeritus of Music, taught at Lawrence University in Wisconsin 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 subsequently studied at the State Conservatory of Music in Munich.  He was awarded the Van Lawrence Fellowship by the Voice Foundation in 1994 for his interest in voice science and pedagogy and is the chair of the editorial board of the NATS Journal of Singing.   Mr. Bozeman was inducted into the prestigious American Academy of Teachers of Singing in 2019.  His former students have sung with Houston, Boston Lyric, Opera Colorado, Washington, Wolf Trap, Seattle, Chicago Lyric, Deutsche Oper Berlin, Dresden, New York City Opera, San Francisco, the Metropolitan, and Santa Fe Opera.

Mr. Bozeman was an active performer of oratorio, including singing the tenor roles in the St. Matthew and St. John Passions, the Christmas Oratorio, the B Minor Mass, the Magnificat, and various cantatas of Bach, Handel’s Messiah, Haydn’s Creation, Mendelssohn’s Elijah, and Vaughn Williams Hodie. He has performed with the Milwaukee Symphony, the Wisconsin Chamber Orchestra, the Green Lake Music Festival, the Purgatory Music Festival of Colorado, the Louisville Bach Society, the Historical Keyboard Society of Wisconsin, and on Wisconsin Public Radio’s “Live from the Elvehjem.”

Mr. Bozeman is a frequent presenter at universities and international voice science conferences (Stockholm, Marseilles, Prague, Zagreb, Copenhagen, Las Vegas, San Antonio, Philadelphia), and has written several articles on the topic of acoustic pedagogy (Choral Journal, Journal of Singing, Logopedics Phoniatrics Vocology, VOICEPrints).  He has published two books on acoustic pedagogy: Practical Vocal Acoustics:  Pedagogic Applications for Teachers and Singers with Pendragon Press, and Kinesthetic Voice Pedagogy: Motivating Acoustic Efficiency with InsideView Press.  Mr. Bozeman has been a featured presenter on voice acoustics at the 2012, 2014, 2018, and 2020 national conferences of NATS, was selected to be a master teacher for the 2013 and 2017 NATS Intern Programs, and was a featured presenter at the 2015 NATS Winter Workshop. He continues to be in demand for seminars and master classes on acoustic pedagogy at universities and interdisciplinary conferences and will be a keynote speaker for the British Voice Association conference in Leeds, 2020, and the International Congress of Voice Teachers in Vienna, 2021.
