 In 1912 Ravel had three ballets premiered. The first, to the orchestrated and expanded version of Ma mère l 'Oye, opened at the Théâtre des Arts in January. The reviews were excellent: the Mercure de France called the score "absolutely ravishing, a masterwork in miniature". The music rapidly entered the concert repertoire; it was played at the Queen's Hall, London, within weeks of the Paris premiere, and was repeated at the Proms later in the same year. The Times praised "the enchantment of the work ... the effect of mirage, by which something quite real seems to float on nothing." New York audiences heard the work in the same year. Ravel's second ballet of 1912 was Adélaïde ou le langage des fleurs, danced to the score of Valses nobles et sentimentales, which opened at the Châtelet in April. Daphnis et Chloé opened at the same theatre in June. This was his largest-scale orchestral work, and took him immense trouble and several years to complete.
