Growl, Scream, Distortion: What MRI and High-Speed Imaging Reveal About Rough Vocals!
Thursday 5th February 2026, 3:00 PM - 5:00 PM (London Time)
The terminology used to describe rough vocal qualities remains far less standardized and considerably less researched than the concepts established in Western classical singing pedagogy. Terms such as vocal fry, fry scream, grunt, death growl, distortion, rattle, and undertone are widely used in contemporary and extreme vocal styles, yet their underlying physiological mechanisms are often inconsistently defined in both pedagogical and scientific contexts.
From an acoustic and voice-physiological perspective, the voice production mechanisms grouped under the umbrella term rough vocals represent a particularly fascinating field of study. Many of these vocal qualities involve double oscillation mechanisms, in which the true vocal folds oscillate in interaction with additional anatomical structures of the vocal tract, such as the ventricular folds or aryepiglottic tissues. These interactions result in complex vibratory patterns that strongly influence perceived sound quality.
This course examines a range of rough vocal mechanisms from a scientific yet practice-oriented perspective. The analysis is based on data from high-speed videoendoscopy as well as three-dimensional vocal tract configurations obtained through magnetic resonance imaging (MRI). By integrating physiological imaging with acoustic analysis, the course provides insight into how different rough vocal qualities are produced and how they differ in terms of vibratory behavior, laryngeal configuration, and vocal tract shaping.
Based on these data, a functional classification of rough vocal mechanisms into distinct groups is proposed. Particular emphasis is placed on distinguishing mechanisms that allow for efficient and sustainable voice production from those that may increase vocal load if applied without appropriate technical control.
Throughout the course, scientific findings are directly linked to vocal pedagogy and clinical practice, supporting informed artistic expression while promoting long-term vocal health.

Certificate in Foundations of Vocology with Adam Roberts
Adam Roberts
This 30-hour Vocology Cohort Intensive provides a comprehensive overview of basic vocal anatomy, physiology, and theories of voice production & perception, fundamentals of vocal health, pathology, evaluation, performance, and habilitation of the speaking and singing voice, and a survey of research, resources, and professional opportunities. Each week, advanced students contribute to cohort-centred learning with additional resources, discussion facilitation, and critical analysis. The course assessment will also be useful for those who wish to prepare for the PAVA recognised designation.

Understanding and Working With Low Self-Esteem in Voice Users
Dr Luke Aldridge-Waddon
Join Dr Luke Aldridge-Waddon as he introduces a cognitive-behavioural approach to understanding and working with low self-esteem. Low self-esteem is associated with a range of psychological and physical health difficulties, including issues relevant to voice disorders and vocal performance. The presentation will first define low self-esteem before discussing psychological factors relevant to its development and maintenance. Luke will review existing research which characterises low self-esteem as a commonly reported experience across voice use and voice disorder groups, with some suggestions for how this might then be approached within a voice clinic and voice coaching context.
