In 1996 Kent Nagano, then music director of the Opéra de Lyon, recognized Jean-Pascal Beintus's talents as composer and began to commission works from him: a concerto for orchestra, a concerto for clarinet and orchestra. Since then, he has written music for nearly every type of ensemble, concert hall and film. He composed a stage music for Le Petit Prince by Antoine de Saint-Exupéry.
His recent projects are the original music of the French TV Star Michel Cymès's documentary based on his book Hippocrates in the Underworld, performed by Renaud Capuçon, and a Fantaisie Concertante for piano, trumpet and orchestra premiered in June 2018 by the Orchestra of Auvergne.
