Swan Lake is generally presented in either four acts, four scenes (primarily outside Russia and Eastern Europe) or three acts, four scenes (primarily in Russia and Eastern Europe). The biggest difference of productions all over the world is that the ending, originally tragic, is now sometimes altered to a happy ending.

Prologue
Some productions include a prologue that shows how Odette first meets Rothbart, who turns Odette into a swan.

Act 1

A magnificent park before a palace

[Scène: Allegro giusto] Prince Siegfried is celebrating his birthday with his tutor, friends and peasants [Waltz]. The revelries are interrupted by Siegfried's mother, the Queen [Scène: Allegro moderato], who is concerned about her son's carefree lifestyle. She tells him that he must choose a bride at the royal ball the following evening (some productions include the presentation of some possible candidates). Siegfried is upset that he cannot marry for love. His friend Benno and the tutor try to lift his troubled mood. As evening falls [Sujet], Benno sees a flock of swans flying overhead and suggests they go on a hunt [Finale I]. Siegfried and his friends take their crossbows and set off in pursuit of the swans.

Act 2

A lakeside clearing in a forest by the ruins of a chapel. A moonlit night.

The "Valse des cygnes" from act 2 of the Ivanov/Petipa edition of Swan Lake
Siegfried has become separated from his friends. He arrives at the lakeside clearing, just as a flock of swans land [Scène. Moderato]. He aims his crossbow [Scène. Allegro moderato], but freezes when one of them transforms into a beautiful maiden, Odette [Scène. Moderato]. At first, she is terrified of Siegfried. When he promises not to harm her, she explains she and her companions are victims of a spell cast by the evil owl-like sorcerer Rothbart. By day they are turned into swans and only at night, by the side of the enchanted lake – created from the tears of Odette's mother – do they return to human form. The spell can only be broken if one who has never loved before swears to love Odette forever. Rothbart suddenly appears [Scène. Allegro vivo]. Siegfried threatens to kill him but Odette intercedes – if Rothbart dies before the spell is broken, it can never be undone.

As Rothbart disappears, the swan maidens fill the clearing [Scène: Allegro, Moderato assai quasi andante]. Siegfried breaks his crossbow, and sets about winning Odette's trust as the two fall in love. But as dawn arrives, the evil spell draws Odette and her companions back to the lake and they are turned into swans again.

Act 3

An opulent hall in the palace

Guests arrive at the palace for a costume ball. Six princesses are presented to the prince [Entrance of the Guests and Waltz], as candidates for marriage. Rothbart arrives in disguise [Scène: Allegro, Allegro giusto] with his daughter, Odile, who is transformed to look like Odette. Though the princesses try to attract the prince with their dances [Pas de six], Siegfried has eyes only for Odile. [Scène: Allegro, Tempo di valse, Allegro vivo] Odette appears (usually at the castle window) and attempts to warn Siegfried, but he does not see her. He then proclaims to the court that he will marry "Odette" (Odile) before Rothbart shows him a magical vision of Odette. Grief-stricken and realizing his mistake, Siegfried hurries back to the lake.

Act 4

By the lakeside

Odette is distraught. The swan-maidens try to comfort her. Siegfried returns to the lake and makes a passionate apology. She forgives him, but his betrayal cannot be undone. Rather than remain a swan forever, Odette chooses to die. Siegfried chooses to die with her and they leap into the lake. This breaks Rothbart's spell over the swan maidens, causing him to lose his power over them and he dies. In an apotheosis, the swan maidens watch as Siegfried and Odette ascend into the Heavens together, forever united in love.

Act I
Scene 1: Raymonda's feast

At the castle of Doris, preparations are under way for the celebrations of the young countess Raymonda’s name day. Countess Sybille, her aunt, chides those who are present, including Raymonda's two friends Henrietta and Clémence, and the two troubadours Béranger and Bernard, for their idleness and their passion for dancing, telling them of the legendary White Lady, the protector of the castle, who warns the Doris household every time one of its members is in danger and casts punishment on those who do not fulfil their duties. The young people laugh at the countess’s superstitions and continue to celebrate. The seneschal of the Doris castle announces the arrival of a messenger, sent by Raymonda's fiancé, the noble crusader knight, Jean de Brienne, bearing a letter for his beloved. Raymonda rejoices when she reads that King Andrew II of Hungary, for whom Jean de Brienne has fought, is returning home in triumph and Jean de Brienne will arrive at the Doris castle the next day for their wedding. Suddenly, the celebrations are interrupted when the seneschal announces the arrival of an uninvited Saracen knight, Abderakhman and his entourage, who have stopped at the castle seeking shelter for the night. Captivated by Raymonda's beauty, Abderakhman falls in love with her at once and resolves to do anything to win her. The party lasts late into the night and, left alone and exhausted by the day, Raymonda lies down on a couch and falls asleep. As she sleeps, she begins to dream that the White Lady appears illuminated by the moonlight and, with an imperious gesture, orders Raymonda to follow her.

Scene 2: The Visions

The White Lady, without making a sound, advances along the terrace. Raymonda follows her in a state of unconsciousness. At a signal from the White Lady, the garden is wrapped in mist. A moment later, the mist vanishes and Jean de Brienne appears. Overjoyed, Raymonda runs into his arms and they are surrounded by glory, knights and celestial maidens. The garden is illuminated by a fantastic light and Raymonda expresses her joy to the White Lady, who interrupts her enthusiasm with a vision of what awaits her. Raymonda wants to return to her fiancé, but instead, she finds Abderakhman, who has taken Jean de Brienne's place. Abderakhman declares his passionate love for her, but Raymonda, though confused and upset, is quick to reject him. Imps and elves appear from everywhere surrounding Raymonda, who begs the White Lady to save her and Abderakhman tries to take Raymonda by force. Raymonda cries out and falls to the ground in a faint. The frightful vision disappears along with the White Lady.

Act II
The Courtyard of the Castle

The feast in honour of Jean de Brienne's arrival is taking place. Raymonda welcomes her guests, but cannot hide her uneasiness caused by Jean de Brienne’s delay. Abderakhman approaches her repeatedly and reveals his passion for her, but remembering the warnings of the White Lady, Raymonda rejects him with contempt. Abderakhman becomes even more insistent and realises the only way to possess Raymonda is by force. He calls his slaves to dance for her, after which he summons his cup bearers and they pour a potion into everyone’s cup, causing all the guests to become drunk. Seizing his chance, Abderakhman grabs Raymonda in an attempt to abduct her, but luckily Jean de Brienne arrives just in time, accompanied by King Andrew II and his knights. Jean de Brienne saves Raymonda from the hands of the Saracens and tries to seize Abderakhman. The King commands the two rivals to put an end to the matter in a duel, during which the White Lady appears on the castle tower. Abderakhman is dazed and dies, slain by Jean de Brienne's sword. Raymonda joyfully embraces her fiancé and the two reaffirm their love as the King joins their hands.

Act III
The Wedding

Raymonda and Jean de Brienne are finally married and King Andrew II of Hungary gives the newly wedded couple his blessing. In his honour, everyone at court is dressed in Hungarian fashion and perform a range of Hungarian-style dances, ending in an Apotheosis where everyone comes together in a knightly tournament.
