Darmstädter Ferienkurse
He was one of the first Danish composers to go to the Darmstädter Ferienkurse, but he never composed serial music. His prolific output includes music for orchestra, chamber music, and vocal and instrumental works. Among his important works are the "Nordisk Sommerpastorale", Op. 51, which won a composition competition arranged by DR (Danish Radio) in 1965, and "Marin", a large orchestral work that includes 44 individual string lines and is regarded as a masterpiece. He died in Birkerød.
