In preparation for producing Spanish choreography, Diaghilev and Leonid Massine enlisted the services of dancer Félix Fernández García, who accompanied the two men with de Falla on a tour of Spain in July 1917, introducing them to dancers and performances in Zaragoza, Toledo, Salamanca, Burgos, Sevilla, Córdoba, and Granada. Massine, Pablo Picasso, and de Falla worked separately on the choreography, sets/costumes, and music for the ballet over subsequent months; after some delays, the ballet was eventually premiered in London at the Alhambra Theatre on 22 July 1919. De Falla was called home to Granada at the last moment to see his dying mother; the premiere was conducted in his stead by Ernest Ansermet.
