Trassonic (Nicola L. Hein and Viola Yip) is an experimental transmedial duo that creates immersive site-specific performances and installations bridging the vibrations of light and sound. Trained as musicians, both look into the ontology of sound and how musical experience can be transformed beyond its common material—sound. For their artistic research project Transsonic, they explore light as an expanded musical material. They research and create performances, improvising between lights and sounds as equally important but dialectical musical materials. 

Hein and Yip have been commissioned by Hong Kong New Music Ensemble, Seanaps Festival Leipzig Gray Center for Arts and Inquiry at the University of Chicago and have presented at New York University, Internationales Musikinstitut Darmstadt, Sonic Lab in SARC at Queen's University Belfast, Huddersfield, Royal Northern College of Music in Manchester, Klex Festival in Kuala Lumpur, De Tanker in Amsterdam, Alte Feuerwache Köln, Fuhrwerkswaage, Willows Nest, Studio Börne 45, West Germany in Berlin and Experimental Intermedia in New York.
