Born in Ath (Belgium) in 1954, Jean-Pierre Deleuze studied at the Royal Conservatory of Brussels with Jean-Marie Simonis, Jacques Leduc and Marcel Quinet. He also attended a class in musical analysis given by Olivier Messiaen at the Centre Acanthes; this experience had a significant impact on his vocation for composition and his aesthetic orientation. Initially, his musical language was influenced by the late works of Alexander Scriabin. The influence of spectral aesthetic and oriental concepts has become increasingly prominent. In 2007 he was elected a member of the Royal Academy of Belgium. In 2014, he was the winner of the SABAM Awards for contemporary music. From 1983 to 1989, he taught harmony at the Royal Conservatory of Brussels where he participated in the research on educational method by Jean-Claude Baertsoen. In 1989 he was appointed Professor at the Royal Conservatory of Mons. He also taught musical analysis at the Queen Elisabeth Music Chapel during the 2001-2004 session.
