Whether merely copying, or else adapting, transcribing (for piano), changing key, style, instrumentation or orchestration – musical arrangement is common outside the world of classical music. Here is a world premiere by contemporary Czech composer Kry?tof Martaka, whose string quartet arrangement of 'Mladi', Jan?cek’s wind sextet has virtually become his master’s 3rd Quartet. Are these works merely ‘in the style of’ or genuine transfigurations, along the lines of Schoenberg’s famous Transfigured Night Op. 4, itself an orchestration of a poem by Richard Dehmel? Judge for yourselves!
