In late November, Chadley Ballantyne, DMA, Associate Professor of Music (Voice) and member of the voice faculty at Stetson University, represented the university at the 2025 MIX Singers Association Seminar in Gliwice, Poland. The two-day live seminar, held November 22–23 at the State School of Music, brought together approximately 120 singers, teachers, and vocal professionals for an intensive program of lectures, workshops, masterclasses, and individual coachings.

Ballantyne was invited as a featured international clinician based on his work in the practical application of acoustic and perceptual voice pedagogy—work that aligns with the broader strengths and priorities of Stetson’s voice program. His participation reflected the program’s emphasis on evidence-informed teaching, stylistic literacy, and the integration of research with applied studio practice.

During the seminar, Ballantyne presented the lecture Articulation in Action: Muscles, Formants, and Resonance, examining how articulatory behaviors shape vocal tract resonance and acoustic output. Using Voce Vista Video, participants observed changes in formant behavior (F1–F4) as they relate to tongue position and vocal tract shape, and explored how purposeful articulatory choices influence clarity, flexibility, and efficiency of tone production across styles.

He also led the workshop Hearing and Feeling Sound: Vibrotactile Feedback in Singing, which explored sound as mechanical energy perceived through both hearing and touch. The session addressed how the body senses vibration, why certain areas—such as the hands—are particularly sensitive, and how tactile awareness can be used as a practical tool for vocal training, coordination, and expressive control.

In addition to these sessions, Ballantyne worked with singers in individual voice lessons and led a public masterclass, offering participants a view into how technical and perceptual concepts are integrated into day-to-day studio and pedagogical practice.

The seminar’s two featured international presenters were Trineice Robinson-Martin (USA), Chair of the Ensemble Department at Berklee College of Music, and Ballantyne. Dr. Robinson-Martin’s lectures and masterclasses focused on rhythm, improvisation, intention, and storytelling within soul, jazz, blues, and R&B. The seminar was hosted and led by Paulina Kujawska and Dominika Płonka, organizational leaders who also contributed sessions on voice–body connection and upper-range mixing and belting, anchoring the event in both local leadership and international exchange.

All sessions were translated into Polish and recorded. Engagement throughout the seminar was strong and consistent, underscoring a shared commitment to thoughtful pedagogy, a deep love of singing, and the exchange of musical culture across traditions and borders.
