While continuously making an effort to improve performance quality, performing musicians don't cease to challenge their own physical and artistic possibilities. We observe two different approaches: the artistic approach, lacking uniformity and objectivity, is an individual trial and error research method, focusing on the whole playing apparatus with conclusions formulated in a personal terminology. The scientific approach, lacking applicability in a practical context, focuses on small segments of the playing apparatus studied under non-realistic laboratory conditions. The purpose of the present research project is to analyze, based on a thorough study of saxophone repertoire, how results of these two research methods, which are essentially complementary, can be combined into a more efficient and uniform research method. Additionally we will, in close partnership with composers, enrich the repertoire and expressive possibilities of the instrument. To achieve this we will use the expertise of the Koninklijk Conservatorium Brussel (performance and composition) and the laboratory of Biomechanics of the VUB (biomechanics). Results will include three components: new compositions, an improved training method for saxophonists which might be relevant to other instruments if proven valid by additional research and finally a series of concerts and recordings to prove validity of the developed training method.
