Swan Lake
Tchaikovsky's influences

From around the time of the turn of the 19th century until the beginning of the 1890s, scores for ballets were almost always written by composers known as "specialists" who were highly skilled at scoring the light, decorative, melodious, and rhythmically clear music that was at that time in vogue for ballet. Tchaikovsky studied the music of "specialists" such as the Italian Cesare Pugni and the Austrian Ludwig Minkus, before setting to work on Swan Lake.

Tchaikovsky had a rather negative opinion of the "specialist" ballet music until he studied it in detail, being impressed by the nearly limitless variety of infectious melodies their scores contained. Tchaikovsky most admired the ballet music of such composers as Léo Delibes, Adolphe Adam, and later, Riccardo Drigo. He would later write to his protégé, the composer Sergei Taneyev, "I listened to the Delibes ballet Sylvia... what charm, what elegance, what wealth of melody, rhythm, and harmony. I was ashamed, for if I had known of this music then, I would not have written Swan Lake." Tchaikovsky most admired Adam's 1844 score for Giselle, which used the Leitmotif technique: associating certain themes with certain characters or moods, a technique he would use in Swan Lake and, later, The Sleeping Beauty.

Tchaikovsky drew on previous compositions for his Swan Lake score. According to two of Tchaikovsky's relatives – his nephew Yuri Lvovich Davydov and his niece Anna Meck-Davydova – the composer had earlier created a little ballet called The Lake of the Swans at their home in 1871. This ballet included the famous Leitmotif, the "Swan's Theme" or "Song of the Swans". He also made use of material from The Voyevoda, an opera he had abandoned in 1868. Another number which included a theme from The Voyevoda was the Entr'acte of the fourth scene and the opening of the Finale (Act IV, No. 29). The Grand adage (a.k.a. the "Love Duet") from the second scene of Swan Lake was fashioned from the final love duet from his opera Undina, abandoned in 1873.

By April 1876 the score was complete, and rehearsals began. Soon Reisinger began setting certain numbers aside that he dubbed "undanceable". Reisinger even began choreographing dances to other composers' music, but Tchaikovsky protested and his pieces were reinstated. Although the two artists were required to collaborate, each seemed to prefer working as independently of the other as possible. At times, Tchaikovsky actually ended up turning to Alina Bryullova, a family acquaintance, for advice on how he should write music for ballet; she later recalled that due to her lack of expertise she "could give him practically no advice."
