Fragments are essential for the realisation of my musical ideas. This commentary explains the musical, aesthetical and philosophical backgrounds to my work, and also the detailed compositional processes employed. Chapter one is a brief overview of Sigimsae and main-tone as found in traditional Korean music, which subsequently become transformed in my composition through the integration with contemporary Western musical elements. Chapter two analyses six compositions in this folio to clarify how unique sounds and forms are developed and achieved through the ever-changing fragment.
