Karl Aage Rasmussen

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, Webs in a stolen Dream and the violin concerto "Sinking through the Dream Mirror". 2015-18 composer in residence with the baroque orchestra Concerto Copenhagen resulting in several new works including "The Four Seasons After Vivaldi" (2016).

Rasmussen has also been engaged in several large projects centered on the music of Franz Schubert. Schubert left his opera Sakontala unfinished and with only the parts for singers sketched out, but Rasmussen completed and orchestrated a performing version of the opera, first performed in Stuttgart 2006. He has further reconstructed what he believes to be Schubert's lost Gastein symphony and created an orchestral version of his melodrama Der Taucher commissioned by the Danish singer Bo Skovhus. He has also completed Robert Schumann's fourth piano sonata.

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.
