A key figure in the genre of liturgical music, Langlais was a student of the renowned organist Marcel Dupré and later served as the organist at the Basilica of Sainte-Clotilde in Paris. Langlais’s music is characterized by its rich harmonies, innovative use of the organ, and incorporation of elements from French impressionism and modal harmonies. Notable works include his "Six Pièces," "Messe Solennelle," and "Trois Paraphrases," which reflect his deep spiritual and liturgical sensibilities. His compositions often blend traditional forms with modern techniques, establishing a unique voice within sacred music.

Today, his works are widely performed and celebrated for their emotional depth and technical demands, solidifying his legacy within the canon of classical and sacred music.
