My string quartet is in two short movements. The first movement is a fugue at the tritone that later transforms by stating the opening idea in a major key. The second movement uses the subject of the fugue and reworks it into a lively scherzo. A sharp contrast of darkness and light is created from the juxtaposition of the tritone and a fifth. The abrupt changes in meter and tempo also contribute to sudden and unpredictable changes in temperament.
