Water Resistance Therapy and Semioccluded Devices for Voice Training

Monday 13th October 2025, 5:00 PM - 7:00 PM (London Time)

Several voice devices to perform water resistance therapy (WRT) and some oscillatory positive expiratory pressure devices (OPEP) (e.g. Acapella Choice, Shaker Medic Plus, New Shaker) are now commonly used for both voice training and voice therapy. Moreover, there are videos in social media demonstrating how to train the voice using devices that are not necessarily supported by evidence. Social media users, especially amateur singers, usually repeat the exercises without any control, supervision, or correction made by someone who knows how to use them appropriately. The questions that motivate the present workshop are: Are these devices truly good for voice training? Are these devices the treatment by themselves? and how much evidence currently supports the use of these devices?

The present workshop will be useful: (1) to provide information about all the commonly used commercial voice devices available in the market; (2) to know if there are studies supporting their effect on voice; and (3) to know the necessary technical details to utilize them in voice training. Several videos in social media show voice exercises with some devices in which there appears to be pressed phonation, possibly a high degree of subglottic pressure, and visible and audible phonatory effort. Evidence widely supports the fact that an excessive subglottic pressure causes increased vocal folds impact stress (vocal folds collision), which in turn could possibly trigger phonotraumatic lesions. In the present workshop you will learn how to control the most relevant variables promoting a more efficient and economic voice production with WRT and OPEP exercises and how to avoid most common mistakes when using these voice tools.

Music Theory Fundamentals for Voice Pedagogues

Dr David Cane

Voice pedagogy has advanced significantly in the last decades in relation to knowledge of the vocal apparatus (anatomy and mechanics), acoustics, and performance psychology (to name just a few subfields) – this is a wonderful thing! Nonetheless, musicianship and the foundations of music theory are still relevant to the teaching and coaching of singers and this course aims to empower voice teachers and coaches with skills to support the fundamental musicianship development of their students.

Exploring Group-Voice for all Ages and Stages!

Cynthia Vaughn

Teaching group-voice classes is an exciting and fun way to teach singing. It affords the singer and teacher opportunities to experience many different aspects of singing in ways that are not possible when working one-one. Join Cynthia Vaughn as she explores the many benefits gained from working in a group, such as opportunities for each student to participate and hear others, chances to experiment with different techniques, styles, and sounds, guided learning from peers, increased awareness of vocal efficiency and effectiveness, and more confidence (and less self-consciousness) in sharing and performing.

Flexible Pedagogy: Teaching Singers with Dynamic Conditions

Joanne Bozeman
Marita Stryker

Is your "flexible" student actually at risk? In recent years, the singing community has seen a vital shift in awareness toward "invisible" conditions like Hypermobility Spectrum Disorders (HSD), hEDS, and POTS. While hypermobility can sometimes feel like a "superpower" for range and flexibility, it often comes with a hidden cost: a higher frequency of voice disorders, respiratory challenges, and autonomic fatigue. Join Joanne Bozeman and Marita Stryker as they unpick the the special challenges and management strategies needed...
