On 2 July 1912, at Boffres (Ardèche), he married Claire de Pampelonne, niece of Vincent d'Indy.
In 1918, he won the Grand Prix Lasserre with the opéra féerique La Belle au bois dormant (1912-1915).
His motets à 4 voix, his 21 Cantiques pour les principales circonstances de la vie liturgique, his Élévations Liturgiques, and his Dix préludes à l'introït place him in the first rank of church musicians.
Besides la Belle au Bois Dormant which has already been mentioned, he wrote the conte lyrique Hyalis, le petit faune aux yeux bleus, pour soli chœurs et orchestre, a Jean de la Lune.
Three works are especially notable: In 1935, he founded the École César Franck with Louis de Serres, becoming its director in 1942.
