Abstract
Born in 1943, Hugues Dufourt is both a philosopher and a composer. If his years of teaching philosophy in Lyon favored Bachelardian studies, his great musical work is no less indebted to the thought of the philosopher of Bar-sur-Aube. Entitled “For a ‘bold new musical spirit’: Gaston Bachelard’s thought at the service of Hugues Dufourt’s musical creation”, this study focuses as much on the concept of “spectral music” as on that related to “imaginary dynamology” (between matter and energy, between theoretical foundation and utopian metaphor). Finally, some scores are analyzed under a Bachelardian prism: Down to a sunless sea (1970), La Tempesta d’après Giorgione (1976-77), Plus-oultre (1990), Euclidian Abyss (1996).
