Karl Aage Rasmussen

Karl Aage Rasmussen (born 13 December 1947 in Kolding, Denmark) is a Danish composer and writer.

Quotation and particularly collage played an important role in his music from the early 1970s, but increasingly he used pre-existing musical material in new connections and for new purposes, most often in a densely woven montage of small idioms which in themselves were too tiny to work as quotes, but were put together so closely as to create entirely new patterns. He continued to use montage technique, but the non-directional expression was gradually replaced by developmental forms. This is apparent in music for the stage and was later continued in works such as A Symphony in Time and the string quartets Solos and Shadows and Surrounded by Scales.

The chamber symphony Movements on a Moving Line marks the beginning of a long period dominated by an interest in time and tempo, here as a kind of time-travel where the same music seems to appear and disappear in different tempi. New conceptions of time, partly related to the self-similarity in fractal mathematics, has dominated his music since then. In more recent years psychological and dramatic dimensions have emerged in works such as the violin concerto, Scherzo with Bells, and Webs in a stolen Dream.

For more than two decades Rasmussen worked as full professor of composition at the Academy of Music in Aarhus, Denmark. Among his students: Louis Aguirre Rovira, Anne Linnet, Kaj Aune, Peter Bruun, Anders Brødsgaard, Karsten Fundal, Michael Nyvang, Jesper Koch, Niels Rønsholdt and Simon Steen-Andersen.

Rasmussen is a prolific writer of essays, so far collected in three volumes. His books on Glenn Gould, Robert Schumann, Sviatoslav Richter, Gustav Mahler, John Cage, Johann Sebastian Bach, George Gershwin, Pyotr Tchaikovsky and music in the 20th century have reached a wide audience.
