Ballet in four acts, written in 1876. The story is based on the ancient fairy tales of the Russian Federation, written by Begichev and Galitzer, and is one of Tchaikovsky's most famous masterpieces. Due to the mediocre level of original choreography and the inexperience of orchestra conductor, the premiere of 1877 failed on February 20th. It was not until 1895 that the performance in Petersburg was an amazing success, and it has since become a classic of ballet in the world.

Swan Lake is still a model for dancers to emulate and a model for realistic dance drama. The story goes something like this: Princess Aogueta, who was turned into a swan by the magician Rodbert, met Prince Siegfried by the lake and told him that only loyal love could free her from the magician's rule, and the prince vowed to love her forever. At the party to choose a bride for the prince, the magician turned into a soldier and deceived the prince with his daughter ogier, who looks like the Tower of Ogle. The prince found himself cheated and rushed to the lake excitedly. With the help and encouragement of Aogueta and the swans, he defeated the magician. The swans have all changed back to human form, and Aogueta and the prince are finally together.

The music of Swan Lake is like a romantic lyric poem. The music of each scene has completed the description of the scene with a profound symphony, promoted the contradiction of the drama, and portrayed the character and mind. These ballet music, which is full of poetic and dramatic power and has the principle of highly symphonic development, is the result of the author's major reform of ballet music, thus becoming dance.
