Claude Ledoux, born in 1960 in Belgium, is a distinguished composer whose journey into music followed his initial studies in science. He began his formal music education at the Conservatoire de Liège, where he encountered notable figures such as Jean-Louis Robert, Philippe Boesmans, Frederic Rzewski, and Henri Pousseur. His explorations in electronic music were furthered at the CRFMW studio under the guidance of Patrick Lenfant.

Seeking to expand his musical horizons, Ledoux studied internationally, participating in a Béla Bartók seminar in Hungary, a seminar led by György Ligeti in Italy (in both Bolzano and Venice), and spending two years in Paris attending IRCAM courses. During this period, he also studied composition with Iannis Xenakis at the University of Paris I.

A successful composer, Ledoux has won numerous competitions, including those held in Lille, Paris, and Lausanne. In 2003, he received the Musical Prize from the Civitella Ranieri Foundation in New York for his recent compositions. His works have been performed across various European cities such as Brussels, Paris, Strasbourg, and Berlin, as well as in Ukraine and Russia. He has also presented his music in North America, performing with the Colorado Orchestra and the Symphonic Orchestra of Montreal, and in Asia, including Vietnam and Japan. From 1998 to 2000, he served as composer in residence at the Ensemble Musiques Nouvelles in Belgium, followed by a residency at the Castello of Umbria in Italy in 2003. More recently, he held a residency at the Brussels Bozar from 2008 to 2009.

Ledoux's fascination with Asian musical traditions has led him to travel extensively in Eastern countries for research and learning. His initial journey to India in 1992 allowed him to explore ethnic music from the Himalayan region to the Rajasthan desert. In 1996, he was awarded a grant from the SPES Foundation to further his studies of oriental music in Vietnam, Cambodia, and Indonesia. In 2004, he traveled to Japan with his wife, Nao Momitani, deepening his understanding of Nô, Bunraku, and Kyôgen.

In addition to his compositional work, Ledoux holds a Master in Communication from the University of Liège. He currently contributes to the musical community as a journalist and serves as a professor of Musical Analysis at the Conservatoire National Supérieur de Musique de Paris in France, as well as a Composition professor at the École Supérieure des Arts, Conservatoire de Mons in Belgium. In the summer of 2008, he taught a course on the Musical Analysis of contemporary music at the Universities of São Paulo and Campinas in Brazil.

Since 2006, he has been a member of The Royal Academies for Science and the Arts of Belgium. In 1998, he co-founded the Atelier Musicien with composers Michel Fourgon and Denis Bosse, creating a collaborative space for experimentation and reflection between composers and performers.
