Guðmundur Steinn Gunnarsson is from Reykjavik, Iceland. His music builds clear patterns without a pulse or meter. In order for that to work he has been developing ways of making animated notation, to be read from computer screens.
He studied composition at Mills College with Alvin Curran, Fred Frith and John Bischoff and in Iceland with Atli Ingólfsson and numerous other Icelandic composers. He participated in the Darmstädter ferienkurse in 2008 and Karlheinz Stockhausen’s courses in Kürten in 2004. He has also participated in masterclasses with Helmut Lachenmann, Tristan Murail and Pauline Oliveros.
