Music in this artificial atmosphere could only flatter the sense of hearing without appealing to the intelligence, excite the nerves and occasionally give a keener point to voluptuousness, by dwelling on a note of elegant sorrow or discreet religiousness. The very church, according to Dittersdorf, had become a musical boudoir, the convent a conservatory. As for the opera, it could not be anything but a lounge for the idle public. The Neapolitan school, which reigned supreme in Europe, provided just the sort of amusement demanded by that public. It produced scores of composers who were hailed as maestri to-day and forgotten to-morrow. Hundreds of operas appeared, but few ever reached publication; their nature was as ephemeral as the public’s taste was fickle, and a success meant no more to a composer than new commissions to turn out operas for city after city, to supply the insatiate thirst for novelty. The manner in which these commissions were carried out is indicative of the result. Composers were usually given a libretto not of their choosing; the recitatives, which constituted the dramatic groundwork, were turned out first and distributed among the singers. The writing of the arias was left to the last so that the singers’ collaboration or advice could be secured, for upon their rendition the success of the whole opera depended; they were, indeed, written for the singers—the particular singers of the first performance—and in such a manner that their voices might show to the best advantage. As Leopold Mozart wrote in one of his letters, they made ‘the coat to fit the wearer.’ The form which these operas took was an absolute stereotype; a series of more or less disconnected recitatives and arias, usually of the da capo form, strung together by the merest thread of a plot. It was a concert in costume rather than the drama in music which was the original conception of opera in the minds of its inventors.

Pietro Metastasio, the most prolific of librettists, was eminently the purveyor of texts for these operas, just as Rinuccini, the idealist, had furnished the poetic basis for their nobler forerunners. Metastasio’s inspiration flowed freely, both in lyrical and emotional veins, but ‘the brilliancy of his florid rhetoric stifled the cry of the heart.’ His plots were overloaded with the vapid intrigues that pleased the taste of his contemporaries, with quasi-pathetic characters, with passionate climaxes and explosions. His popularity was immense. He could count as many as forty editions of his own works and among his collaborators were practically all the great composers, from Handel to Gluck and Cimarosa. As personifying the elements which sum up the opera during this its most irrational period we may take two figures of extraordinary eminence—Niccola Porpora and Johann Adolf Hasse.

I

Niccola Porpora (1686-1766), while prominent in his own day as composer, conductor, and teacher (among his pupils was Joseph Haydn), is known to history chiefly by his achievements as a singing master—perhaps the greatest that ever lived. The art of bel canto, that exaltation of the human voice for its own sake, which in him reached its highest point, was doubtless the greatest enemy to artistic sincerity and dramatic truth, the greatest deterrent to operatic progress in the eighteenth century. Though possessed of ideals of intrinsic beauty—sensuousness of tone, dynamic power, brilliance, and precision like that of an instrument—this art would to-day arouse only wonder, not admiration. Porpora understood the human voice in all its peculiarities; he could produce, by sheer training, singers who, like Farinelli, Senesino, and Caffarelli, were the wonder of the age. By what methods his results were reached we have no means of knowing, for his secret was never committed to writing, but his method was most likely empirical, as distinguished from the scientific, or anatomical, methods of to-day. It was told that he kept Caffarelli for five or six years to one page of exercises, and then sent him into the world as the greatest singer of Europe—a story which, though doubtless exaggerated, indicates the purely technical nature of his work.

Porpora wrote his own vocalizzi, and, though he composed in every form, all of his works appear to us more or less like solfeggi. His cantatas for solo voice and harpsichord show him at his best, as a master of the florid Italian vocal style, with consummate appreciation of the possibilities of the vocal apparatus. His operas, of which he wrote no less than fifty-three, are for the most part tedious, conventional, and overloaded with ornament, in every way characteristic of the age; the same is true in some measure of his oratorios, numerous church compositions, and chamber works, all of which show him to be hardly more than a thoroughly learned and accomplished technician.

But Porpora’s fame attracted many talented pupils, including the brilliant young German, Hasse (1699-1783), mentioned above, who, however, quickly forsook him in favor of Alessandro Scarlatti, a slight which Porpora never forgave and which served as motive for a lifelong rivalry between the two men. Hasse, originally trained in the tradition of the Hamburg opera and its Brunswick offshoot (where he was engaged as tenor and where he made his debut with his only German opera, ‘Antiochus’), quickly succumbed to the powerful Italian influence. The Italians took kindly to him, and, after his debut in Naples with ‘Tigrane’ (1773), surnamed him il caro sassone. His marriage with the celebrated Faustina Bordoni linked him still closer to the history of Italian opera; for in the course of his long life, which extends into the careers of Haydn and Mozart, he wrote no less than seventy operas, many of them to texts by the famed Metastasio, and most of them vehicles for the marvellous gifts of his wife. While she aroused the enthusiasm of audiences throughout Europe, he enjoyed the highest popularity of any operatic composer through half a century. Together they made the opera at Dresden (whither Hasse was called in 1731 as royal kapellmeister) the most brilliant in Germany—one that even Bach, as we have seen, was occasionally beguiled into visiting. Once Hasse was persuaded to enter into competition with Handel in London (1733), the operatic capital of Europe, where Faustina, seven years before, had vanquished her great rival Cuzzoni and provided the chief operatic diversion of the Handel régime to the tune of £2,000 a year! Only the death of August the Strong in 1763 ended the Hasses’ reign in Dresden, where during the bombardment of 1760 Hasse’s library and most of the manuscripts of his works were destroyed by fire. What remains of them reveals a rare talent and a consummate musicianship which, had it not been employed so completely in satisfying the prevailing taste and propitiating absurd conventions, might still appeal with the vitality of its harmonic texture and the beauty of its melodic line. Much of the polyphonic skill and the spontaneous charm of a Handel is evident in these works, but they lack the breadth, the grandeur and the seriousness that distinguish the work of his greater compatriot. Over-abundance of success militates against self-criticism, which is the essential quality of genius, and Hasse’s success was not, like Handel’s, dimmed by the changing taste of a surfeited public. Hasse’s operas signalize at once the high water mark of brilliant achievement in an art form now obsolete and the ultimate degree of its fatuousness.

Hasse and Porpora, then, were the leaders of those who remained true to the stereotyped form of opera, the singers’ opera, whose very nature precluded progress. They and a host of minor men, like Francesco Feo, Leonardo Vinci, Pasquale Cafaro, were enrolled in a party which resisted all ideas of reform; and their natural allies in upholding absurd conventions were the singers, that all-powerful race of virtuosi, the impresarios, and all the great tribe of adherents who derived a lucrative income from the system. Against these formidable forces the under-current of reform—both musical and dramatic—felt from the beginning of the century, could make little head. The protests of men like Benedetto Marcello, whose satire Il teatro alla moda appeared in 1722, were voices crying in the wilderness. Yet reform was inevitable, a movement no less momentous than when the Florentine reform of 1600 was under way—the great process of crystallization and refinement which was to usher in that most glorious era of musical creation known as the classic period. Like the earlier reform, it signified a reaction against technique, against soulless display of virtuosity, a tendency toward simplicity, subjectivity, directness of expression—a return to nature.

Though much of the pioneer work was done by composers of instrumental music whose discussion must be deferred to the next chapter, the movement had its most spectacular manifestations in connection with opera, and in that aspect is summed up in the work of Gluck, the outstanding personality in the second half of the eighteenth century. In the domain of absolute music it saw its beginnings in the more or less spontaneous efforts of instrumentalists like Fasch, Foerster, Benda, and Johann Stamitz. First among those whose initiative was felt in both directions we must name Giovanni Battista Pergolesi, the young Neapolitan who, born in 1710, had his brilliant artistic career cut short at the premature age of twenty-six.

II

Pergolesi was the pupil of Greco, Durante, and Feo at the Conservatorio dei Poveri at Naples, where a biblical drama and two operas from his pen were performed in 1731 without arousing any particular attention. But a solemn mass which he was commissioned to write by the city of Naples in praise of its patron saint, and which was performed upon the occasion of an earthquake, brought him sudden fame. The commission probably came to him through the good offices of Prince Stegliano, to whom he dedicated his famous trio sonatas. These sonatas, later published in London, brought an innovation which had no little influence upon contemporary composers; namely, the so-called cantabile (or singing) allegro as the first movement. Riemann, who has edited two of them,[1] calls attention to the richly developed sonata form of the first movement of the G major trio especially, of which the works of Fasch, Stamitz, and Gluck are clearly reminiscent. ‘The altogether charming, radiant melodies of Pergolesi are linked with such conspicuous, forcible logic in the development of the song-like theme, always in the upper voice, that we are not surprised by the attention which the movement aroused. We are here evidently face to face with the beginning of a totally different manner of treatment in instrumental melodies, which I would like to call a transplantation of the aria style to the instrumental field.’[2] We shall have occasion to refer to this germination of a new style later on. At present we must consider another of Pergolesi’s important services to art—the creation of the opera buffa.[3]
