Can anyone tell me who choreographed Aurora's solo in the Kirov vision scene? If it's by Lopukov (it does begin with the same phrase -- a grand battement a la seconde tombe that begins his Lilac fairy solo), did Sergeyev take the notation for the solo West with him and was it ever used in the RB version before Ashton's became standard? Or did they use the Gold Fairy variation that Petipa had sustituted in '89?

When the RB first did Sleeping Princess in 1939, Sergeyev used the Gold Fairy's music for Aurora's solo - choreography presumably 'after Petipa'. They used this music till Ashton made his new version to the 'right' music in 1952.

In my knowledge this variation made by Petipa in respond to Mathilda Kschesinskaya's request.

Do you mean the Gold Fairy's solo was added by MK's request?

Petipa appears to have replaced the original variation music for Aurora with the Gold Fairy music prior to the premiere of the ballet. Tchaikovsky made a change in the passage leading up to the variation in order to accommodate the difference of key. Wiley has documented this well in TCHAIKOVSKY'S BALLETS.
