danger which threatens him, and, try as he may to collect himself, fear gets possession of him; he mumbles to himself, cries aloud, and makes a final appeal for mercy before he runs away. The perplexity which seizes them all at the discovery of Leporello is the point of union of the situation; the truth and energy with which the nature of each person is expressed giving it the stamp of life and power.[153] Leporello's position is totally different when Don Giovanni arrogantly orders him to invite the statue of the Commendatore to sup with them (Act II., 9). The mysterious sounds which he has just heard, and the marble figure, terrify him; but his master threatens with drawn sword; one fear overmasters the other, and he now persuades himself to address the statue--now turns in terror to his master. The musical expression of fear by means of intervals of sevenths--[See Page Image] but how characteristic is the difference between this cringing appeal for pity, and the former energetic cry extorted, as it might be, on the rack! The terror increases at each successive attempt to address the statue, while the energy of each address decreases, and dies away at last into a plaintive parlando. The orchestra at the same time adds the expression of insolent mockery, which is not less characteristic of the situation, in a playful but sharply accented {DUET--LEPORELLO} (175) passage, wherein the flutes are made especially effective. As soon as Leporello's fears are verified and the statue actually moves, he succumbs to his terror, and Don Giovanr^ steps forward. Fear is a stranger to him; he sees the statue nod its head, and demands a more distinct answer; he puts his question plainly and decidedly; the statue answers by "Si." Leporello behaves as though struck by a thunderbolt, and has no idea but flight; even Don Giovanni is affected, and feels the supernaturalness, but he retains his self-possession; and, in the expression of trembling haste with which it hurries on the conclusion, the orchestra mingles something of the humorous impression which is given by the unexpected _dénouement_ of the situation. The harmonic construction is here masterly in the extreme. From the beginning ^ to this point only the principal key and the one next related to it have been used; but now the interrupted cadence upon C major transports us to another atmosphere, and the altered movement of the orchestra is expressive of energetic activity.
