Alessio Castellacci is a voice embodiment teacher, contemporary dancer, and sound artist based between Berlin and Rome. Since 2007 he has worked internationally across performance, pedagogy, and sound design, developing an interdisciplinary approach to voice and movement. His teaching focuses on the relationship between voice, body, and perception — exploring how sound emerges from the living, sensing body. Through his method Embodied Voice Flow, Alessio invites participants into a deep listening practice, where vocal expression becomes a form of movement, relational awareness, and self-regulation. He has taught workshops and seminars for over 15 years at art universities, festivals, and independent venues throughout Europe. His practice integrates elements from somatic disciplines (Body-Mind Centering, Release Technique, Experiential Anatomy), voice research (Estill Voice Training), and systemic psychotherapeutic approaches such as Internal Family Systems. Together with Slovenian artist Irena Z. Tomažin, he co-runs The World is Sound, a Berlin-based platform dedicated to experimental and embodied voice practices.
