Manfred Trojahn initially studied flute at the Music Academies in Braunschweig and Hamburg, where he was later a composition pupil of Diether de la Motte. At the end of the 1970s he received a stipend to stay at the Villa Massimo in Rome and lived for a time in Paris and Hamburg. He has been Professor of Composition at the Robert Schumann Music Academy in Düsseldorf since 1991.
He was President of the German Composers’ Union from 2004 to 2006. His present compositional output is available from Bärenreiter Publishers.
The main emphasis of his compositional activity lies in the orchestral area, which especially reflects his expressionistically coloured, freely tonal formal language built on dodecaphony, as well as in chamber music.
