At a young age , Marie-Jeanne Serero started attending the Higher National Conservatory of Music of Paris (Conservatoire National Supérieur de Musique de Paris) where she was awarded numerous first prizes in the specialized music theory class as well as in harmony, counterpoint, orchestration, piano accompaniment and song directing.
She combines both her passions: the voice (by working at the Higher National Conservatory of Music of Paris and in various European festivals as a pianist or choir conductor), and orchestral music writing (with film-scoring, composition and arrangements, contemporary creations, opera and choreographic compositions).
At the Higher National Conservatory of Music of Paris, she began teaching a song director class before getting into orchestration teaching and also supervising the music to image class.
For numerous years, she has performed concerts all over Europe (in duos with Rostropovitch, P. Fontanarosa, Dider Lockwood, O. Charlier, R. Pasquier, Christiane Eda-Pierre, the Ludwig Quatuor).
She is then very busy in France and abroad, working with important personalities and production houses who have asked her to orchestrate and direct prestigious musical projects for either cinema, theatre or live shows and to complete albums of very diverse genres of music.
