S&V is a work in two movements for amplified saxophone, violin and ECG signals. It was commissioned by saxophonist Franziska Schroeder and violinist Gascia Ouzounian. This piece develops explores non-real time usage of biosignals to generate musical materials as well as live interaction. In S&V, ECG signals are not only employed as an instrument to directly produce or manipulate sounds, but pre-recorded data sets of ECG signals are used to generate musical materials such as melodic and rhythmic patterns. This was to explore these signals in a more structured way, whilst still using the heart as an instrument in real time.
