restoratives. Asdrubale, who is on the way to Rome that he may wed Eugenia, overwhelms her with reproaches, and throws himself on a couch in despair. Eugenia has risen, and before Asdrubale can explain himself, Bocconio returns, and to his astonishment finds the scene completely altered. At this point the terzet begins, and expresses most charmingly the confusion and embarrassment of the three personages, who are all in the dark as to each other's conduct, and who put restraint on themselves even in their extremity of suspense. The orchestra carries on the threads independently, joined by the voices, sometimes apart and interrupted, to suit the situation, sometimes together. An excellent effect is given by the sharply accented expression of involuntary painful emotion contrasting with the reserve which otherwise prevails in the terzet. The whole tone of the piece is masterly; while never overstepping the limits of comic opera, it successfully renders the deep agitation of mind of all the three characters. This is contrived, not by the mixture of a comic element in the person of Bocconio, who rather approximates to the frame of mind of the other two, but by the cheerful tone which penetrates the whole without any loss of truth of expression. This opera again stopped short of completion, and a third seems to have had the same fate. A terzet for male voices, which is preserved in duplicate draft, was intended for the first scene of a comic opera. An opera by Accoromboni, "Il Regno delle Amazoni," was, according to Fétis, performed at Parma in 1782, as well as elsewhere,[31] with success, and the words of the terzet leave little doubt that this, too, was among the "little books" Mozart had looked through, and that it suggested to him an experiment which must almost have coincided in point of time with the two just mentioned. It can scarcely have been the imperfections of the libretti alone which caused Mozart to leave these operas unfinished, but also the improbability of ever bringing them to performance. The brilliant reception accorded to the Italian maestri, Sarti and Paesiello, in Vienna, only caused {MOZART AS AN OPERA COMPOSER.} (64)
