The circumstances were, in fact, very favourable. The principal difficulty against which Gluck had hitherto to contend, viz., the deep-rooted partiality for Italian music and its accepted forms, did not exist in Paris; for opera seria in its developed form had made as little way there as the display of fine execution, and even lovers of Italian music would have been loth to introduce its abuses and exaggerations of set purpose. French opera, on the contrary, in accordance with the genius of the nation, made its first principle dramatic and characteristic expression, which could only be attained by correct yet free treatment of musical forms, and by well-considered treatment of recitative. Choruses, too, which were for Gluck an important aid to climax and dramatic effect, were indispensable in French opera; and since Rameau's time the orchestra had been successfully employed as a means of characteristic expression. But the French school had hitherto failed to combine dignity and beauty with their dramatic force and expression; and here Gluck's Italian training enabled him to supply the deficiency. As far as comic opera was concerned, Grétry had preceded him with similar efforts, and had accustomed the ear of the Parisians to the mingling of French and Italian music. But to carry out such a reformation in the grand opera required a man of commanding qualities; and such an one Gluck had proved himself to be. The choice of subjects was a happy one. Racine's tragedy was known as a masterpiece to the whole nation, and unless the adaptation were very clumsily made, success for the poetic share of the opera was assured. The advance on earlier operas is a very decided one. An important event forms the centre of the plot, dramatic contrasts, passions, and characters, are effectively portrayed. It is true that the spirit of the age of Louis XIV. runs {FRENCH OPERA.} (28)
