in 2011 i wrote a pure data patch to put on my iphone within
the framework of the rjdj-app. the patch filters chords from ambient
noise. these chords contain all 12 pitches, spread out over several
octaves. (its something i derived from the theories of the russian
composer nicolai obouchov, who died in 1954 in paris). with this app,
i made several recordings while being on a train. intoko is part of
a recording made on july 3rd, 2012 at around 11:30 pm while the train
ice 22 approaches the station koblenz, coming from mainz. at the end
one hears the station announcement.
hans w. koch develops performances and open forms for various, often interdisciplinary ensembles and creates (sound-)installations, sometimes involving computers and digital media. the search for hidden aspects of everyday tools, such as household electronics, hairdryers, metal wool, old computers (and traditional instruments as well) takes place alongside his explorations of sounds and musical structures. when working with digital media, he explores boundaries and implicit (de)faults, in order to arrive at interactions that keep lives of their own and react to human input in unpredictable ways. this also extends to his use of computers as musical instruments in a rather physical manner.art in general for him is sculpturing thoughts in different materials. personally he prefers conceptual approaches: more thought, less material. 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. since fall 2012 he is lecturer for hybrid sound computing at the institute for music and media in duesseldorf.
