This amusing and light hearted description of how the larynx and the vocal tract function was put together by the television program "Newton's Apple" in answer to a question from a listener. It simply, but graphically, teaches the 'source/filter' theory of voicing and clearly demonstrates how long-term muscular adjustments of the system give rise to those particular perceptual characteristics that allow us to perceive one voice as different from another. It is a quick, simple but excellent introduction to the whole topic of the human voice.

This video was prepared for and presented at the 17th Symposium "Care of the Professional Voice" in New York in June, 1988. The paper accompanying the DVD has been published in The Journal of Voice, Vol.3, No.4, pp 342-350 Raven Press Ltd., New York, USA.
Fibrescopic video laryngoscopy was performed on five professional singers as each sang "Happy Birthday" and parts of the "Star Spangled Banner" in six different Voice Qualities. Aryepiglottic narrowing was present in all singers in Twang, Belting and Opera Qualities. Spectrographic analysis showed this narrowing gave rise to the presence of the "singers formant". It clearly shows how this narrowing of the vocal tract produces a voice that is perceived as louder without any adverse effects on the larynx.
An alternative treatment for vocal nodules in children

Yelling does not have to be harmful. Many children and adults yell well and do not hurt their voice. They are belting just like the famous Broadway Belters, eg. Ethel Merman, Donna Summer or Whitney Houston.
This programme analyses belting, physiologically and acoustically. It graphically demonstrates how the larynx and vocal tract can be intelligently shaped to produce this high intensity vocalisation safely.
The second part of the DVD is extracted from a 45 minute session with a child aged five years who has vocal nodules. This is his first contact with his voice therapist. He is shown the basic elements and then combines them to produce a creditable belt by the end of the session. Like the other children who have been taught to belt by Alison, his nodules resolved in a few months and he continues to yell, safely.
