Her husband is gone to the tavern for refreshment and Nedda is left alone. There is a little trouble in her mind caused by the fierceness of Canio's voice and looks. Does he suspect? But why yield to such fancies and fears? How beautiful the mid-August sun is! Her hopes and longings find expression in the "Ballatella"--a waltz tune with twitter of birds and rustle of leaves for accompaniment. Pretty birds, where are you going? What is it you say? Mother knew your song and used once to tell it to her babe. How your wings flash through the ether! Heedless of cloud and tempest, on, on, past the stars, and still on! Her wishes take flight with the feathered songsters, but Tonio brings her rudely to earth. He pleads for a return of the love which he says he bears her, but she bids him postpone his protestations till he can make them in the play. He grows desperately urgent and attempts to rape a kiss. She cuts him across the face with a donkey whip, and he goes away blaspheming and swearing vengeance. Then Silvio comes--Silvio, the villager, who loves her and who has her heart. She fears he will be discovered, but he bids her be at peace; he had left Canio drinking at the tavern. She tells him of the scene with Tonio and warns him, but he laughs at her fears. Then he pleads with her. She does not love her husband; she is weary of the wandering life which she is forced to lead; if her love is true let her fly with him to happiness. No. 'Tis folly, madness; her heart is his, but he must not tempt her to its destruction. Tonio slinks in and plays eavesdropper. He hears the mutual protestations of the lovers, hears Nedda yield to Silvio's wild pleadings, sees them locked in each other's arms, and hurries off to fetch Canio. Canio comes, but not in time to see the man who had climbed over the wall, yet in time to hear Nedda's word of parting: A stanotte--e per sempre tua saro--"To-night, and forever, I am yours!" He throws Nedda aside and gives chase after the fugitive, but is baffled. He demands to be told the name of her lover. Nedda refuses to answer. He rushes upon her with dagger drawn, but Beppe intercepts and disarms him. There is haste now; the villagers are already gathering for the play. Tonio insinuates his wicked advice: Let us dissemble; the gallant may be caught at the play. The others go out to prepare for their labors. Canio staggers toward the theatre. He must act the merry fool, though his heart be torn! Why not? What is he? A man? No; a clown! On with the motley! The public must be amused. What though Harlequin steals his Columbine? Laugh, Pagliaccio, though thy heart break!
