A march accompanies the entrance of Pizarro. {2} Pizarro receives his despatches from Rocco, and from one of the letters learns that the Minister of Justice, having been informed that several victims of arbitrary power are confined in the prisons of which he is governor, is about to set out upon a tour of inspection. Such a visit might disclose the wrong done to Florestan, who is the Minister's friend and believed by him to be dead, and Pizarro resolves to shield himself against the consequences of such a discovery by compassing his death. He publishes his resolution in a furious air, "Ha! welch' ein Augenblick!" in which he gloats over the culmination of his revenge upon his ancient enemy. It is a terrible outpouring of bloodthirsty rage, and I have yet to hear the singer who can cope with its awful accents. Here, surely, Beethoven asks more of the human voice than it is capable of giving. Quick action is necessary. The officer of the guard is ordered to post a trumpeter in the watch-tower, with instructions to give a signal the moment a carriage with outriders is seen approaching from Seville. Rocco is summoned, and Pizarro, praising his courage and fidelity to duty, gives him a purse as earnest of riches which are to follow obedience. The old man is ready enough until he learns that what is expected of him is [Musical excerpt--"Morden!"] whereupon he revolts, nor is he moved by Pizarro's argument that the deed is demanded by the welfare of the state. Foiled in his plan of hiring an assassin, Pizarro announces that he will deal the blow himself, and commands that a disused cistern be opened to receive the corpse of his victim. The duet which is concerned with these transactions is full of striking effects. The orchestra accompanies Rocco's description of the victim as "one who scarcely lives, but seems to float like a shadow" with chords which spread a cold, cadaverous sheen over the words, while the declamation of "A blow!--and he is dumb," makes illustrative pantomime unnecessary. Leonore has overheard all, and rushes forward on the departure of the men to express her horror at the wicked plot, and proclaim her trust in the guidance and help of love as well as her courageous resolve to follow its impulses and achieve the rescue of the doomed man. The scene and air in which she does this ("Abscheulicher! wo eilst du hin?") is now a favorite concert-piece of all dramatic singers; but when it was written its difficulties seemed appalling to Fräulein Milder (afterward the famous Frau Milder-Hauptmann), who was the original Leonore. A few years before Haydn had said to her, "My dear child, you have a voice as big as a house," and a few years later she made some of her finest successes with the part; but in the rehearsals she quarrelled violently with Beethoven because of the unsingableness of passages in the Adagio, of which, no doubt, this was one:-- [Musical excerpt--"sie wird's erreichen"]
