"Giselle" was a great artistic and commercial success. "Le Constitutionnel" praised Act 2 for its "poetic effects". "Moniteur des théâtres" wrote that Grisi "runs [and] flies across the stage like a gazelle in love". One critic made a detailed analysis of the music in "La France Musicale". He thought the Act 1 waltz "ravishing", and noted that the scene of Berthe's narrative was filled with "quite new" harmonic modulations. He praised other moments in Act 1 (especially the mad scene), and was in raptures with the music of Act 2, singling out the entrance of the Wilis and the viola solo played through Giselle's last moments. He thought the flute and harp music accompanying Giselle as she disappeared into her grave at ballet's end "full of tragic beauty."
