Ep.172

Vocal pedagogy expert Ken Bozeman returns to the podcast, joining Alexa to explore laryngeal vs. acoustic registration, how vowel modification impacts vocal range, and the role of sensory feedback in refining vocal technique. 

KEY TAKEAWAYS

  • Laryngeal registration involves physical changes in the larynx and muscle use to shape vocal folds for different pitches. Acoustic registration focuses on the interaction between pitch, harmonics, and vowel resonance to produce different timbres. Understanding both helps singers and teachers refine vocal techniques.
  • To understand vowel resonance and acoustic registration, try these exercises: modify vowel shapes to note resonance changes, whisper different vowels to explore natural resonances, sing with nasal consonants to feel nasal resonance, focus on harmonics and resonance shifts, and use vocal fry and whispers to identify resonances. 
  • To apply acoustic registration concepts, adjust vowel shapes for timbres like whoop (smooth), close (sizzly), and open (buzzier). Practise smooth transitions and use nasal consonants to explore resonances. Focus on sensory feedback, experiment with expression, and train your ear for harmonics. Record and analyse your singing for improvement.
  • Ken recommends that singers and teachers focus on developing a strong understanding of acoustic principles and how they can be applied to improve vocal technique. He suggests using tools like the chiaroscuro whisper to explore and understand vocal resonances.


BEST MOMENTS 

“Laryngeal registration deals with how the vocal folds are shaped for pitch, while acoustic registration is determined by the relationship between the pitch being sung and the potential harmonics of that pitch.”

“In non-classical styles, the goal is to keep the entire range as speech-like as possible, which may involve compromises due to the different paint set of each pitch.”

“Open timbre in acoustic terms is more oral. You feel it in the mouth.”

“Attitude, is it an emotion or is it an attitude?”
