Scene 1

A public audience at Riccardo's palace, attended by his supporters, but also by his enemies who hope for his demise.

Riccardo (Gustavo) reviews the list of guests who will attend an upcoming masked ball. He is elated to see the name of the woman he loves on the list – Amelia, the wife of his friend and advisor, Renato (Count Anckarström). (Aria: La rivedrò nell'estasi / "There I will be in ecstasy to see her again"). When Renato arrives, he tries to warn Riccardo about the growing conspiracy against him (aria: Alla vita che t'arride / "Your life, so full of joy and hope"), but Riccardo refuses to listen to his words.

Next, Riccardo is presented with a complaint against a fortune-teller named Ulrica (Madame Arvidson), accused of witchcraft. A magistrate calls for her banishment, but Oscar the page defends her (Aria: Volta la terrea / "Turning her eyes from the earth"). Riccardo resolves to investigate for himself and tells the members of the court to disguise themselves and to meet him at Ulrica's lodging later that day.

Scene 2

At Ulrica's dwelling

Ulrica summons her magical powers: Re dell'abisso, affrettati / "King of the abyss, make haste". Disguised as a fisherman, Riccardo arrives before the others. He makes the fortune of a sailor named Silvano come true by spiriting a document of promotion into his pouch, convincing the crowd of the truth of Ulrica's powers. When he realizes that Amelia is coming to see Ulrica, he hides and watches. Alone with Ulrica, Amelia confesses that she is tormented by her love for Riccardo, and asks for a means to bring peace to her heart. Ulrica tells her to gather a certain herb with magical powers; Riccardo resolves to be there when she does so. Amelia leaves.

Now Riccardo presents himself again, along with all of the courtiers, and asks to have his fortune told. (Aria: Di' tu se fedele / "Tell me if the sea awaits me faithfully"). Ulrica reveals that he will be killed by the next man who shakes his hand. He laughingly dismisses her prophecy and offers his hand to the courtiers, who refuse to take it. Renato arrives and shakes Riccardo's hand in greeting. Riccardo's true identity is now revealed and he is acclaimed by the people.

Act 2

On the outskirts of the town, at the gallows-place. Midnight

Amelia, conquering her fears, has come here alone to pick the herb of which Ulrica told her (Aria: Ma dall'arido stelo divulsa / "But when I have plucked the herb"). She is surprised by Riccardo, who has come to meet her, and the two finally declare their love for each other. Unexpectedly, Renato arrives, and Amelia covers her face with her veil before he can recognize her. Renato explains to Riccardo that the conspirators are pursuing him, and his life is in danger. Riccardo leaves, making Renato promise to escort the veiled woman safely back to town, not asking her identity. When the conspirators arrive, they confront Renato; in the struggle, Amelia's veil drops. Renato assumes that Amelia and Riccardo have been involved in an adulterous love affair. He asks the two leaders of the conspiracy, Samuel and Tom, to meet him the next day.

Act 3

Scene 1

Renato's house

Renato has resolved to kill Amelia for the dishonour she has brought on him. She protests her innocence and begs to see her son one last time. (Aria: Morrò, ma prima in grazia / "I will die, but first, a kindness"). Renato relents, and declares that it is Riccardo, not Amelia, who deserves to die (Aria: Eri tu che macchiavi quell'anima / "You were the one who stained her soul").

Samuel (Count Ribbing) and Tom (Count Horn) arrive, and Renato asks to join their plot, pledging the life of his son as proof of his sincerity. They agree to draw lots to decide who will kill Riccardo. Amelia is forced to draw the winning name – Renato.

Oscar, the page, arrives with invitations to the masked ball; Samuel, Tom and Renato agree that this is where the assassination will take place.

Scene 2

The ball

Riccardo, torn between love and duty, has resolved to renounce his love for Amelia and send her and Renato back to England (Aria: Ma se m'è forza perderti / "But if I am forced to lose her").

At the ball, Renato tries to learn from Oscar what costume Riccardo is wearing. Oscar at first refuses to tell (Aria: Saper vorreste / "You want to know"), but he finally answers: a black cloak and a red ribbon. Riccardo manages to identify Amelia and tells her of the decision he has made. As they say goodbye, Renato stabs Riccardo. The wounded Riccardo discloses that though he loved Amelia, she never broke her marriage vows. He pardons all the conspirators, bidding farewell to his friends and his country as he dies.

Giuseppe Verdi

Place of birth: Le Roncole, Italy
Place of death: Milan, Italy

composer giuseppe verdi


Verdi is one of our most beloved opera composers with hits like Rigoletto, Aida and Falstaff. He was a very productive composer, writing nearly 30 operas spanning from 1839 to 1893.

In his twenties tragic events unfolded when Verdi lost his two children in infancy and shortly thereafter his first wife. He remarried years later to the renowned soprano Giuseppina Strepponi who became his life companion.

Verdi is known for modernising Italian opera by writing long passages of through-composed music and unifying acts for a more continuous dramatic development. This is more noticeable in his later works. He came to dominate the opera scene after an era of bel canto composers such as Rossini, Donizetti and Bellini.


“To copy the truth can be a good thing, but to invent the truth is better, much better. ”


Verdi was a food lover, adored Shakespeare and the only piece of chamber music he wrote was a string quartet.

Verdi and Wagner were born in the same year. They were known to be rivals even though they never met.

The original plot for Un ballo in maschera is based on the true story of the Swedish King Gustavo III who was shot at a masked ball in 1792, dying 13 days later of his injuries.

The opera was censored and therefore Verdi and Somma had to make changes to the original setting and characters. It was first changed to Una vendetta in Domino, set in Stettin, but finally resulted in the title we know today, Un ballo in maschera, set in Boston in colonial times. The opera premiered at the Teatro Apollo in Rome in 1859.

Today it is one of the top 30 most performed operas worldwide.
