Léo Dupleix (born 1988 in Paris) is a French composer and musician.
As a composer, he explores the possibilities of just intonation, taking as a starting point the harmonic spectrums of notes and their possible interaction. He develops music driven by an attraction to minimalism, polyphonic writing, ritournelle, ritual, and repetition.
He undertakes specific work with the harpsichord, for which he develops his own system of non-tempered tuning. This instrument is used within groups (such as Les Certitudes with
Félicie Bazelaire and Juliette Adam, in a duo with Fredrik Rasten, or in the Guédon-Levy-Dupleix trio) as well as in solo concerts. He also uses electronic instruments, synthesizers, and sine tone generators that underlines specific frequencies of acoustic instruments sound (resonnant trees, for ensemble) or can be treated as instruments (Rasten-Heilbron-Lane-Dupleix quartet).
He also offers compositions for ensembles in Europe and Japan, as well as for solo instruments (for the guitar and harpsichord) and electro-acoustic compositions.
After studying jazz piano at the Koninklijk Conservatorium Brussel, he moved to Japan in 2014, a decisive one-year experience where he connected with numerous Japanese improvisers and composers of the experimental scene(Taku Sugimoto, Toshi Nakamura, Tetuzi Akiyama, Minami Saeki, Ura Hiroyuki). Since 2016, he has been living in his hometown, Paris. He regularly works in France, Berlin, Europe, and Japan.
He keeps performing as well in the group vierge noir e, with
Anna Gaïotti and Sigolène Valax, a three headed musical chimera that explores extreme body and sound states, ranging from silence to excess, through a blend of electronic, acoustic, and concrete sounds. Occasionally, he composes music for film, notably for the films of director Rémi Allier (
Les petites mains, winner of the 2019 César for Best Short Film;
Zinneke).
