Pittsburgh Ballet Theater Presents: Swan Lake - An evil enchantment and a mysterious love story give wings to a ballet that has captured the public imagination since 1895. Together with the live PBT Orchestra, PBT returns to Swan Lake for two weekends around Valentine’s Day. Swan Lake exemplifies classical technique – from the ballet en blanc swan scenes to the Black Swan’s famous 32 fouettés. But it’s the undulating port de bras of the swans – a movement quality unique to Swan Lake – that lends its own mystique to the classical vocabulary. Set to the stirring themes of Tchaikovsky’s score, the split personalities of Odette and Odile mirror the age-old battle between good and evil.
