The later ensembles belong immediately to the action of the piece. At the close of the third act Sandrina and Belfiore awake from refreshing sleep healed of their madness. Belfiore seeks acceptance of Sandrina, who now acknowledges herself to be Violante, but she, abashed at his declarations of love, bids him depart, and prepares to go herself. Neither, however, can summon resolution to part, and after several attempts, they sink at last in one another's arms, forgetful of all but their newly found happiness. This situation, somewhat coarsely rendered by the poet, has been transformed by the composer into an admirable piece of character-painting (27). A long accompanied recitative passes into an elaborate and effective Adagio, in which professions of love alternate with reproaches. The Andantino (3-8), which follows is lighter in tone, and well expresses alternations of repulsion and attraction. The oboes are employed with a charming effect of longing appeal to the words: "_Cont_. Lei mi chiàma?--_Sandrina_. Signor, nö. Lei ritoma?--_Cont._ Oibö, oibö!" Finally, the joy of the united pair flows forth in an Allegro, which gives full opportunity for display on the part of the singers. Especially to be admired is the art with which the intense and genuine expression of emotion is tempered by the timidity of the Count and the coquetry of Sandrina, in a happy union of the pathetic and the comic which keeps the whole within the limits of' opera buffa. The rapid winding-up of the plot in the recitative dialogue, and the short animated ensemble with which the opera concludes (28) are no doubt intended not to weaken the effect of the great duet. The finales (12, 22) of the first and second acts are masterpieces; the separate characters act and react on each other {OPERA BUFFA.} (222) in a way which is admirably true to life. Two conditions are essential to the elevation of such pieces into musical works of art; important points in the action or the characters must be brought out by prominent motifs, and the fundamental idea of the situation must be grasped and maintained in one motif which shall serve as a clue to the whole.
