In 1913, Nijinsky’s assistant, Marie Rambert (1888–1982), asked Igor Stravinsky for a copy of the piano score so that she could record Nijinsky’s choreography for Le Sacre du Printemps (The Rite of Spring: music by Igor Stravinsky; sets and costumes by Nikolai Roerich; choreography by Vaslav Nijinsky; first performance on May 28, 1913. Théâtre Champs-Élysées, Paris). In her diary, Nijinska relates the events surrounding the appointment of Marie Rambert as an assistant to Nijinsky for Le Sacre: “After visiting the studio of [Emile] Jacques-Dalcroze, Diaghilev claimed that he was concerned that our artists would not be able to master the difficult rhythms . . . and that he had invited Dalcroze’s best pupil . . . to teach us eurhythmics. I was burning with indignation and protested loudly, ‘I cannot see what a Dalcroze pupil can teach our artists. We are already familiar with Stravinsky’s music, having danced in two ballets, Petrouchka and The Firebird, where we had no trouble with the rhythms of his complicated scores’.”
