 Malmasson's compositions are written in an expressive, extended-tonal style which uses a great deal of harmonic vocabulary borrowed from the style of Olivier Messiaen (notably in the early work "Un feu ardent dans un silence noir et froid" for pianoforte).Malmasson is often inspired by space and astronomy ("Mare Nostrum" for Orchestra, "Coro").In addition to being the musical director of the city of Puteaux wind orchestra, a post he has held since 1988, Jean-Yves Malmasson is also director of Orchestre Philharmonique des Yvelines et de l'Ouest Francilien (Versailles).
