Tchaikovsky died on 6 November 1893. People started to take more interest in his music after his death. Lev Ivanov was the assistant Ballet Master at the Mariinsky Theatre in St. Petersburg. He designed new dances for Act 2. This act was presented on 1 March 1894 in a concert at the Mariinsky in memory of Tchaikovsky. Pierina Legnani danced Odette. The revised act was a great success. It was presented again with even greater success. Marius Petipa was the Ballet Master at the Mariinsky. He was impressed with the success of these two presentations. He made the decision to stage the complete ballet at the Mariinsky. He designed the dances for Acts 1 and 3 while Ivanov designed the dances for Acts 2 and 4.
