although the moral shock is great it is with actual physical fear that his teeth chatter. The whole sequence of characteristic expression in the scene receives its full significance only by contrast with Leporello's cowardice. Donna Anna's passion, which Don Giovanni is constrained to oppose with a force equal to her own; the dignified bearing of the Commendatore, forcing Don Giovanni at length reluctantly to draw the sword;[150] the duel[151] with its horrifying result--all these afford a rapid succession of exciting and harrowing points, scarcely leaving room for the comic element, which nevertheless is there, and kept actively before us without doing injury to the harmony of the whole. What a force of artistic expression is displayed in the eighteen bars of andante which close the introduction! The death which ends the pain of the Commendatore, the mingled pity and triumph of Don Giovanni, the horror and fear of Leporello, are blended into such harmony as to leave the mind--relieved from suspense--full of true emotion. The unusual combination of three bass voices seems as though expressly chosen for the serious tone of the situation; the stringed instruments accompany the voices in the simplest manner, with a few sustained notes for the horns and bassoons, and only in the concluding symphony do the oboes and flutes enter with a plaintive chromatic passage.
