Spectral music: analysis of Rastlose Liebe by Hugues Dufourt

In traditional tonal music, tonality is established to create sense of hierarchy as musical structure. In twelve-tone music movement led by Schoenberg, the equally important twelve tones have destroyed the sense of hierarchy and direction in musical structure. Then in the next wave of spectral music with pioneers such as Hugues Dufourt, the sense of direction and structure is recreated with new ways of harmony and formality without traditional tonality. In this thesis of oral presentation, the theory of spectral music is examined with a chosen piece, Rastlose Liebe by Hugues Dufourt, to understand the emergence of spectral music and the origin where it came from, as a way to understand and to analyze spectral music and furthermore to create a piece in this genre.
