Swan Lake is a romantic ballet in four acts. Pyotr Ilyich Tchaikovsky wrote the music. In 1871 he wrote a little ballet about swans for his nieces and nephews. He used some of the music from this ballet for Swan Lake.  The story of the ballet is based on a German fairy tale. This tale was probably tweaked by Tchaikovsky and his friends during the ballet's early discussion stages.
 
Swan Lake is about a prince named Siegfried. He falls in love with the Swan princess, Odette. She is a swan by day, but a young woman at night. She is under a magic spell that can only be broken by a man who will make a promise to love her for all time. Siegfried makes the promise. He is tricked though by the magician who cast the spell. The ballet ends with the deaths of Siegfried and Odette.

The ballet was first performed on 4 March 1877 at the Bolshoi Theatre in Moscow, Russia. Critics looked upon it as a failure for many reasons. In 1895 some changes were made to the ballet. It was then performed at the Mariinsky Theatre in St. Petersburg, Russia. This time the critics thought Swan Lake a great success. Most performances today are based on this 1895 version.

Libretto and score 
In 1871 Tchaikovsky was passing the summer in the Ukraine with his sister Alexandra Davydova. It was in her home at Kamenka that he wrote a short ballet about swans for her children to perform. The story of the ballet was based on "The Lake of Swans", a German fairy tale. Tchaikovsky used a musical theme from this children's ballet in the mature Swan Lake. Little else is known of this ballet for children.  

In 1875 Vladimir Begitchev asked Tchaikovsky to write a ballet about swans. Begitchev was the official in charge of the repertory of the Imperial Theatres. Tchaikovsky accepted his invitation to write the ballet. He told Rimsky-Korsakov, "I accepted the work, partly because I want the money, but also because I have long had the wish to try my hand at this kind of music." In August he had completed sketches for two acts. He finished the ballet on 10 April 1876.

It is uncertain who wrote the libretto of the ballet. Both Begitchev and the dancer Vasily Geltzer were credited in the programme. They likely based it upon discussions with the artists who met at Begitchev's salon. They also used tales from Johann Musäus's Volksmärchen der Deutschen (178286), a collection of German fairy and folk tales.

Composition 

Tchaikovsky had no experience writing ballet music for the professional theatre when he accepted Begitchev's invitation. In 1875  he began work on Swan Lake. It was his first ballet. He studied the ballet music of other writers. He liked the music and ballets of Leo Delibes. Tchaikovsky thought Delibes's music was pretty and tuneful. Tchaikovsky however would base Swan Lake on a symphonic scale. Writing the music for Swan Lake was a way for Tchaikovsky to avoid the reality of being a homosexual in czarist Russia. Russia was a repressive state. Homosexuals were sent to prison, exiled, or banished. Symphonies did not ease the stress in the way ballet music did; he had to put too much of his inner life into symphonies. He was hired to write Swan Lake in May 1875. He completed the music in April 1876. The official responsible for the music at the Bolshoi Theatre thought Tchaikovsky's music impossible to understand. A leitmotif in Tchaikovsky's little ballet music for his nieces and nephews came to be called the "Song of the Swans". Tchaikovsky used this leitmotif in Swan Lake.

Characters in the ballet 

 Odette, the Swan Princess. Odette is a swan by day (like her sister swans) and a maiden by night. She appears in Acts 2 and 4, and very briefly in Act 3.
 Prince Siegfried, Odette's lover. Prince Siegfried falls in love with Odette and promises to be true to her forever. He betrays Odette by accident. He appears in all four acts.
 Von Rothbart, is a magician who keeps Odette and her sister swans trapped in a magic spell. He takes the shape of an owl. He is defeated at the end of the ballet. He appears in Acts 2, 3, and 4. He is sometimes referred to as Rotbart. His name means "Red Beard".
 Odile, Von Rothbart's daughter. She is disguised as Odette. She tricks the prince into promising his love to her at a ball, and, in doing so, the Prince betrays Odette. She appears only in Act 3. Sometimes the ballerina playing Odette also performs the role of Odile.
 Wolfgang, the Prince's tutor. Wolfgang usually appears in Act 1. He becomes drunk on the wine. He appears in Acts 1 and 3.
 Benno, the Prince's friend. Benno suggests to the Prince and his friends that they hunt the swans in Act 1. Benno appears in Acts 1 and 3.
 Queen Mother, Siegfried's mother. The Queen Mother wants her son to choose a bride. She usually gives him a crossbow as a birthday gift in Act 1. She appears in Acts 1 and 3. The Queen Mother is a pantomime role.

Music 

John Warrack points out that Tchaikovsky put the drama in the story into music: "By making B the key of the tragedy, he initiates a musical "plot" with the dark forces of Rothbart tending to drag the tonality down into flatter keys. The main action, on the other hand, lies on the key area of A." Tchaikovsky balanced all the musical components of the work. "The divertissements are in his lightest, most appealing musical manner", Warrack writes, "The dances that further the plot have rather greater musical substance, while the scenes of narrative and action are in what was found his "symphonic" manner." Critics said Tchaikovsky's music was "too noisy, too 'Wagnerian' and too symphonic".

First performance 
Rehearsals for Swan Lake began before Tchaikovsky finished the score, and took place over 11 months. Everyone involved in the production had never heard such a complex score for a ballet. They described the music as "undanceable". Even the conductor threw his hands up in despair over the music.

The choreographer Julius Reisinger was incompetent, and the sets lacked a cohesiveness because they were designed by three different men. In addition, the Bolshoi Theatre was suffering at the time from problems including the lack of a ballet master who could develop a production based on the score. The role of Odette was not given to a first rate dancer but instead to a second rate talent. The reason may have been political.

Swan Lake was first performed on 4 March 1877 at the Bolshoi Theatre in Moscow. Julius Reisinger designed the dances. Pauline Karpakova danced Odette. She put some numbers she liked from other ballets into Swan Lake. The ballet was a failure. In 1883 the Bolshoi dropped the ballet from its repertory. At that time, the sets were falling apart. It was not until 1901 that Alexander Gorsky staged a new production of Swan Lake for the Bolshoi.

What people thought about the ballet 

The first performance of Swan Lake was a disaster. Herman Laroche wrote, "I must say that I had never seen a poorer presentation on the Bolshoi stage. The costumes, decor, and machines did not hide in the least the emptiness of the dances. Not a single balletomane got out of it even five minutes of pleasure." He praised the music. He wrote that Tchaikovsky was "in excellent humour ... he was fully at the height of his genius." Tchaikovsky's brother Modest wrote, "The poverty of the production, meaning the décor and costumes, the absence of outstanding performers, the Ballet Master's weakness of imagination, and, finally, the orchestra ... all of this together permitted [Tchaikovsky] with good reason to cast the blame for the failure on others." The ballet was a moderate success with theatre-goers however. It was presented 33 times between its première at the Bolshoi in 1877 and its final performance in 1883.

St. Peterburg revision, 1895 

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.

Riccardo Drigo was the conductor of the Mariinsky orchestra. He dropped some numbers from the ballet. He orchestrated three piano numbers from Tchaikovsky's Op. 72. He then put them in the ballet. These three numbers were "L'Espiègle", "Valse Bluette", and "Un poco di Chopin". He then put a number into Act 3 which he may have written himself.

Tchaikovsky's brother Modest changed the ballet's story a little for the revision. He gave the ballet a happy ending.  The new Swan Lake was presented on 27 January 1895 at the Mariinsky. Pierina Legnani danced both Odette and Odile. The ballet was a great success. This version of the ballet is the one generally seen today.

Thirty-two fouettés en tournant 

Swan Lake is famous for the 32 fouettés en tournant in Act 3. These fouettés are danced at the end of the "Black Swan" pas de deux by the ballerina playing Odile.  The pas was an afterthought of Tchaikovsky's. It was not included in the original production. It consists of the opening adagio followed by a variation for the male dancer. This is followed by a variation for the ballerina. The whole concludes with a brisk movement for both dancers that includes the fouettés. Pierina Legnani first danced the fouettés in the Mariinsky production of 1895.  Ballet-goers were uncertain about the 32 fouettés. Some thought they were just a stunt. Others found them exciting. These ballet-goers went to every performance to count the number of turns.

Other early productions 

Swan Lake became known in Europe and the United States not long after the revised version was presented at the Mariinsky Theatre in 1895. It was first presented in Europe at Prague in June 1907. It was first presented in the United States at the Metropolitan Opera House in December 1911. Diaghilev's Ballets Russes presented a two-act Swan Lake in London in 1911.  The Ballets Russes presented a one-act version in London in 1925. The complete Swan Lake was first presented in England by the Sadler's Wells Ballet in November 1934. Ballerinas portraying Odette include Mathilde Kchessinska, Anna Pavlova, and Margot Fonteyn. Pavel Gerdt was the Prince Siegfried of the 1895 St. Petersburg production. Nijinsky and Rudolph Nureyev have also performed Prince Siegfried.

Structure 
The score used in this comparison is Tchaikovsky's score. It may be different from Riccardo Drigo's score which is usually performed today.  The titles for each number are taken from the original published score. Some of the numbers are titled simply as musical indications, those that are not are translated from their original French titles.
