The various scenes, the conflicting passions, are marvellously reproduced in the music of Mozart. From the very opening where Leporello keeps impatient watch to the unearthly scene between the Statue and the libertine, there is an unceasing flow of exquisite melody that is not only appropriate to the characters and the action, but is also the fullest and most complete expression of the plot and incidents. Berlioz objected to the florid air sung by Donna Anna, on the ground that it was not essentially dramatic; but there have been singers who could express passion in a roulade and sway the hearer by a trill; such is the power of personal conviction. It is true that the last finale is an anti-climax. The interest ceases with the punishment of the hero, and although attempts have been made to give the opera with this finale, they have not been successful; and the curtain rightly falls with the descent of Don Giovanni. To speak in detail of the myriad beauties of this masterpiece would be simply to analyze the score measure by measure. Its immortal melodies are known throughout the world. Musicians of all schools have vied with men eminent in the other walks of life in the most extravagant eulogy. In this opera is seen the universality of Mozart's genius. His knowledge of humanity, his sympathy with all classes and conditions of men. It is the most realistic of his works; it is at the same time the most ideal. Not without reason did Goethe pass over Cherubini and von Weber, Auber and Rossini, Beethoven and the rest, and say that Mozart was the one who should have set his Faust to music. Not without reason did he mention him with Shakespeare. "Cosi fan tutte" and "La Clemenza di Tito" were written hurriedly. Neither is an advance in the career of the composer. The first is a return to the old-fashioned _opera buffa_; the second looks longingly towards the ancient _opera seria_. The plot of the former is vulgar, improbable and stupid; and that of the latter is extremely dull. The music of "Cosi fan tutte" is often delightful, as in the famous quintet, the second terzet; but there is not the same degree of psychological characterization found in his three great operas; and there are many concessions to popular taste. "La Clemenza di Tito" belongs to that class of compositions described by the French as _grandes machines officielles_. The finale is worthy of Mozart; but as a whole the opera is inferior to "Idomeneo" even in the instrumentation.
