Hossein Hadisi is a Research Associate at Darwin College, University of Cambridge. He studied his PhD in Composition with Michael Finnissy at the University of Southampton. Hossein’s research focuses on the core of the philosophy and expressive artistic attitude of the traditional Persian improvisation school of Avaz and studies the improvisatory processes that form the compositional aspect of a performance in that tradition. The techniques and formal behaviours and the reasons for such choices are explored to investigate the possible compositional techniques that could be built based on the Avaz tradition. In this research, he will demonstrate possible applications of such techniques through his own compositions, and discuss other approaches that could be derived from them.
