The Use Of Supraglottic Constrictions In Singing
Thursday 18th November 2021, 5:00 PM - 7:00 PM (London Time)
Supraglottic activity is usually associated with hyper-functional voice disorders and is considered as a reflection of vocal misuse and abuse.
Even though both medial and anterior-posterior compressions have been accepted as endoscopic signs of vocal hyperfunction, several studies have observed that supraglottic activity may also be present in normal speaking and singing voice production.
The degree of supraglottic activity may be influenced by several independent variables that commonly change during regular voice production (e.g. level of loudness, pitch, and phonatory task).
Previous studies have evaluated specific variables that may affect the degree of supraglottic tissue displacement in professional voice users.
The present course was designed to provide information about the variables that influence supraglottic activity in singing and why this activity should not be necessarily considered as a sign of vocal hyperfunction.

Redefining Ethical Practice in Voice Teaching!
Dr Justin John Moniz
Join Dr Justin John Moniz as he examines ethical practice in voice teaching through a structured, evidence-informed framework for sustainable, student-centered pedagogy. Although voice teaching operates outside formal licensure models common to allied professions, teachers hold significant responsibility for students’ vocal function, artistic development, and long-term well-being. This course addresses that gap through a five-part paradigm grounded in the NATS Code of Ethics, contemporary research, and applied studio practice.

Training the Vocal Athlete: Strategies for Efficient Belting in the 21st Century Market!
Dr Wendy LeBorgne
In the fast-paced world of contemporary commercial music (CCM) and musical theatre, belting is no longer a niche vocal effect; it is an athletic requirement. This evidence-informed, interactive workshop bridges the gap between vocal science and studio application. Led by voice pathologist and author Dr. Wendy LeBorgne, participants will dissect the physiological, acoustic, and aerodynamic demands of healthy belting. From establishing baseline vocal fitness to navigating the subtle stylistic differences between Broadway and West End aesthetics, this session will provid an actionable blueprint to build powerful, injury-resistant voices.
