Jean Dubé began playing the piano at the age of three and gave his first public performance at four. As a child prodigy, he won a Steinway piano at the age of nine in the national competition “Jeunes Prodiges Mozart à Paris”. In the same year, he performed as a soloist with the Philharmonic Orchestra of Radio France at the Maison de la Radio, broadcast live on France Musique.

At ten, he won first prize in piano at the Conservatory of Nice, becoming both the youngest soloist in France and the youngest first-prize winner in the history of the conservatory. At eleven, he was unanimously admitted with the highest praise from the jury into Jacques Rouvier’s class at the Conservatoire National Supérieur de Paris, making him the youngest musician in the institution. By the age of fourteen, he won first prize in piano at the National Conservatory of Music and Dance in Paris, along with the Monique de la Bruchollerie Special Prize.

At sixteen, he won first prize at the International Francis Poulenc Piano Competition in Brive-la-Gaillarde (1997), and at seventeen, he won first prize at the Jeunesses Musicales competition in Bucharest (1998).
