Born in 1960 in Neuilly-sur-Seine (France), Alain Celo eventually devoted himself to music after completing his high-school diploma with a major in sciences, and winning a First Prize at a national-level school competition in music (1978).

He studies the viola with Stéphane Wiener and Marie-Thérèse Chailley at the music school of Boulogne-Billancourt, chamber music with Gérard Caussé, musical analysis with Alain Louvier, and then furthers his music education at the Ecole Normale de Musique de Paris with Tasso Adamopoulos (solo viola of the Orchestre National de France back then).

He is selected to join the Orchestre National de Metz Grand Est in 1986, and has worked there since then.

He involved himself in numerous chamber music ensembles such as the Duo Rolla, Trio Leonore, Melodia quartet and Austrasia quartet.

As a regular member of the Ensemble Stravinsky since its beginnings in 2001, he performs many concerts of XXth and XXIst century music each year, as far as a viola part is requested. He played the premieres of "Secrète Perspective" for viola and ensemble, and "Aeon" for viola and clarinet by Dominique Lemaître.
