Editing Ernani (section)

===Act 1===
''Mountains of Aragon''

The bandits demand the reason for Ernani's gloom (Chorus: ''Evviva! Beviam! Beviam!'' / "To you we drink"; ''Ernani pensoso!'' / "Ernani, so gloomy? Why, oh strong one, does care sit on your brow?"). Ernani replies that he loves Elvira (Recitative: "Thanks, dear friends"; Cavatina: ''Come rugiada al cespite'' / "As the flower turns to the sun"), who is about to be married against her will to old Gomez de Silva (''O tu che l'alma adora''). He asks the bandits to abduct her.

''In Elvira's chamber''

Elvira worries about her upcoming marriage (Scena: "Now sinks the sun and Silva does not return"; [[Cavatina]]: ''Ernani, Ernani involami'' / "Ernani, Ernani, save me") as servants deliver Silva's wedding presents to her. She reaffirms her love for Ernani (''Tutto sprezzo che d'Ernani'' / "I scorn everything which does not speak to my heart of Ernani"). King Carlo enters, declaring his love for Elvira, who rejects it, admitting she is in love with another man. As Carlo attempts to use force, she grasps a dagger, while Ernani suddenly arrives to defend her. Carlo recognizes Ernani as the leader of the bandits. (Trio: "Tu se' Ernani! Me 'l dice lo sdegno" / "You are Ernani! The scorn that invades this soul tells that to me"). Ernani replies that Carlo killed his father, robbed him of his lands and forced him into a life of banditry. As he invites Carlo to fight, Silva appears and sees them both, guessing correctly that they are trying to seduce Elvira (''Infelice!... e tu credevi''... ''che mai vegg'io!'' / "Dreadful sight"; Silva's cavatina: "Unhappy man! You thought this lovely...was yours").

Silva wants to fight both the seductors to restore his honour, when Riccardo approaches and recognises the king. Silva is horrified and apologizes to the king, who in turn decides to save Ernani, saying that is one of his servants. Ernani whispers to Elvira to prepare to flee, while Carlo starts talking with Silva about his rights for the Holy Roman Empire.
