The third and last group is comprised of the "Manzoni Requiem," the operas "Aïda," "Othello," and the lyric drama "Falstaff." The last named might almost be classified by itself, representing as it does the extreme phase of Verdi's involuntary adaptation of Teutonic dogmas both ancient and modern. In spite of his obvious intention to make this his masterpiece, it presents a line of departure not suited to his most felicitous style of writing. However, this _dramma lirico_ has borne fruit in so far as to be a source of inspiration to Puccini, Mascagni and Leoncavallo, although _their_ effusions take the form of "tragic operettas." In spite of the display of virile power in "Falstaff," Verdi reached his highest development in the orchestration of the Requiem, in the musical contents of "Aïda," and in the dramatic continuity of "Othello." In all these later works one finds unquestionable evidence of Wagnerian influence, at the least in respect to externals. Notwithstanding Verdi's repudiation of any such intentions, no composer surrounded by the spirit of the times could do other than progress. The most noticeable improvements in the third group consist of freer use of the dissonant element, better declamation, higher regard for faithful interpretation, painstaking finish of minor details, and above all an extreme advance in the art of instrumentation. The functions of the orchestra become more and more important, and the tonal colors acquire a richer and warmer hue. The scoring of the Requiem is dignified, religious, yet emotional. That of "Aïda" breathes the very atmosphere of its Egyptian setting. In "Othello," the orchestration is essentially dramatic and impassioned. "Falstaff" accepts the fundamental principles of Gluck, and the orchestra is raised to prominence equal to that of the voices. As a result of this concession, Verdi found Wagner's orchestral resources indispensable to his needs, and the resultant modern effects are a pleasant surprise. The vocal parts and the orchestra are here logically balanced, though Verdi's marvellous gift as a writer of pure and limpid melody continues in evidence.
With the evolution of this third period was instituted one of the mightiest transformations in the history of Italian opera. That country has as yet been unable to replace him. The efforts of Ponchielli, Gomez, Boïto, Sgambati, Buonamici, Puccini, are certainly praiseworthy, but sink into insignificance when compared with the splendid attainments of their venerable and venerated model. As to the rocket-like ascent and descent of Mascagni together with the present notoriety of Leoncavallo, time alone will decide whether the path they have chosen be meritorious or meretricious.
