As the differences between opéra and opéra comique faded, the two main houses in Paris came more into competition, although the Salle Favart saw the premieres of more innovative works: Debussy's "Pelléas et Mélisande" (1902), Dukas' "Ariane et Barbe-bleue" (1907), Ravel's "L'heure espagnole" (1911), and French premieres of works by Puccini and Falla.
