Anyone can get the music score of Tchaikovsky's Swan Lake from any decent music shop. Foyle's Bookshop in London, for example, or Chappell's music shop also in London, would be likely to stock the music score of Swan Lake. You go to the music floor, search for composers alphabetically, look for Tchaikovsky, and there should be the score for the Swan Lake ballet. There may be two different scores - a full orchestral score or a "piano" score (a shortened score). Or you may search the Internet, which may give you many sites from which you could order the score.

Peyotr Illych Tchaikovsky Marius Petipa is credited with the original choreography

swan lake was composed (written) in 1875-1876 by Tchaikovsky
