Hans W. Koch develops performances and open forms for various, often interdisciplinary ensembles and creates sound installations. The search for hidden aspects of everyday tools, such as household electronics, hairdryers, metal wool, old computers (and traditional instruments as well) is combined with the exploration of sounds and musical structures.
In order to create systems that live on their own and react to human input in unpredictable ways, he explores boundaries and implicit (de)faults of soft- and hardwares. This also extends to his use of computers as musical instruments in a rather physical manner. He considers art sculpting thoughts in different materials. Personally he prefers conceptual approaches: More thought, less material.
Equally important to him is his work with teachers and non-professional musicians, with whom he explores experimental ways of music making in seminares and workshops.
During spring semester 2007 he was teaching composition and experimental sound practices as visiting professor at the California Institute of the Arts, Los Angeles. In 2008 his piece „the benchmark consort“ won an award of distinction at the Ars Electronica in linz / austria. Currently he teaches at the institute for Music and Media in Duesseldorf.
