The vibrating structure inside the larynx—specifically the true vocal folds—that generates the raw acoustic sound wave.
The core of the Estill curriculum found in training manuals revolves around the "Figures for Voice." These are exercises designed to give the vocalist conscious control over specific anatomical structures. EVT identifies three primary systems involved in voice production: the Power Source (respiration), the Vibrator (the vocal folds), and the Resonator (the vocal tract). estill voice training pdf
This taxonomy is revolutionary because it legitimizes all styles of voice use. In classical pedagogy, "Belting" is often dismissed or labeled dangerous. EVT, however, deconstructs Belting into its mechanical components—specifically, a tilted cricoid cartilage, thick vocal folds, and a narrowed aryepiglottic sphincter. By understanding the anatomy of Belting, a singer can learn to execute it safely and healthily. Similarly, the "Twang" quality, essential for commercial and musical theater styles, is isolated and taught as a resonance strategy rather than a nasality issue. This scientific categorization allows singers to cross genres safely, moving from an operatic aria to a rock ballad with anatomical precision.

Control the thickness and tension of the folds to manage effort and intensity. By understanding the anatomy of Belting, a singer
A breathy, light quality with minimal vocal fold contact.
