But Mozart’s cosmopolitanism was broader than this. He was but six years of age, gifted with a marvellous power of absorption, and impressionable to a degree, when his father began with him and his eleven-year-old sister, also highly talented and already an accomplished pianist, the three-years’ journey—or concert tour, as we should say to-day—which took them to Munich, to Vienna, to Mannheim, to Brussels, Paris, London, and The Hague. They played before the sovereigns in all these capitals and were acclaimed prodigies such as the world had never seen. How assiduously young Mozart emulated the music of all the eminent composers he met is seen from the fact that four concertos until recently supposed to have been original compositions were simply rearrangements of sonatas by Schobert, Honauer, and Eckhardt.[41] Similarly, in London he carefully copied out a symphony by C. F. Abel, until recently reckoned among his own works; and a copy of a symphony by Michael Haydn, his father’s colleague in Salzburg, has also been found among his manuscripts. But the most powerful influence to which he submitted in London was that of Johann Christian Bach, who determined his predilection for Italian vocal style and Italian opera.

Already, in 1770, when he and his father were upon their second artistic journey, he tried his hand both at Italian and German opera, with La finta semplice and Bastien und Bastienne, and it is significant that during their production he was already exposed to the theories of Gluck, who brought out his Alceste in that year. But it must be said that neither of the two youthful works shows any traits of these theories. The first of them failed of performance in Vienna and was not produced until later at Salzburg; the other was presented under private auspices at the estate of the famous Dr. Messmer of ‘magnetic’ fame. But in the same year Mozart, then fourteen years of age, made his debut in Italian opera seria with Mitradite at Milan. This was the climax of a triumphal tour through Italy, in the course of which he was made a member of the Philharmonic academies of Verona and Bologna, was given the Order of the Golden Spur by the Pope, and earned the popular title of Il cavaliere filarmonico.

Upon his return to Salzburg young Mozart became concert master at the archiepiscopal court, and partly under pressure of demands for occasional music, partly spurred on by a most extraordinary creative impulse, he turned out works of every description—ecclesiastical and secular; symphonies, sonatas, quartets, concertos, serenades, etc., etc. He had written no less than 288 compositions, according to the latest enumeration,[42] when, at the age of twenty-one, he was driven by the insufferable conditions of his servitude to take his departure from home and seek his fortune in the world. This event marked the period of his artistic adolescence. Accompanied by his mother he went over much of the ground covered during his journey as a prodigy, but where before there was universal acclaim he now met utter indifference, professional opposition and intrigue, and general lack of appreciation. However futile in a material sense, this broadening of his artistic horizon was of inestimable value to the ripening genius.

While equally sensitive to impressions as before, he no longer merely imitated, but caught the essence of what he heard and welded it by the power of his own genius into a new and infinitely superior musical idiom. Now for the first time he rises to the heights, to the exalted beauty of expression which has given his works their lasting value. Already in the fullness of his technical power, equipped with a musicianship which enabled him to turn to account every hint, every suggestion, this virtuoso in creation no less than execution fairly drank in the gospel of classicism. Mannheim became a new world to him, but in his very exploration of it he left the indelible footprints of his own inspiration.

If he met the Mannheim musicians on an equal footing it followed that he could approach those of Paris with a certain satirical condescension. But, if his genius was recognized, professional intrigue prevented his drawing any profit from it—he was reduced to teaching and catering to patronage in the most absurd ways, from writing a concerto for harp and flute (both of which he detested) to providing ballets for Noverre, the all-powerful dancer of the Paris opera. His adaptability to circumstances was extraordinary. But all to no avail; the total result of his endeavors was the commission to write a symphony for the Concerts spirituels then conducted by Le Gros. Nowhere else has he shown his power of adaptability in the same measure as in this so-called ‘Paris Symphony.’ It is, as Mr. Hadow says, perhaps the only piece of ‘occasional’ music that is truly classic. The circumstances of its creation appear to us ridiculous but are indicative of the musical intelligence of Paris at this time. The premier coup d’archet, the first attack, was a point of pride with the Paris orchestra, hence the piece had to begin with all the instruments at once, which feat, as soon as accomplished, promptly elicited loud applause. ‘What a fuss they make about that,’ wrote Mozart. ‘In the devil’s name, I see no difference. They just begin all together as they do elsewhere. It is quite ludicrous.’ For the same reason the last movement of the Paris Symphony begins with a unison passage, piano, which was greeted with a hush. ‘But directly the forte began they took to clapping.’ Referring to the passage in the first Allegro, the composer says, ‘I knew it would make an effect, so I brought it in again at the end, da capo.’ And, despite those prosaic calculations, the symphony ‘has not an unworthy bar in it,’ and it was one of the most successful works played at these famous concerts. Yet Paris held out no permanent hope to Mozart and he was forced to return to service in Salzburg, under slightly improved circumstances.[43]

It is nothing short of tragic to see how the young artist vainly resisted this dreaded renewal of tyranny, and finally yielded, out of love for his father. His liberation came with the order to write a new opera, Idomeneo, for Munich in 1781. This work constitutes the transition from adolescence to maturity. It is the last of his operas to follow absolutely the precedents of the Italian opera seria, and its success definitely determined the course of his artistic career. In the same year he severed his connection with the Salzburg court (but not until driven to desperation and humiliated beyond words), settled in Vienna, and secured in a measure the protection of the emperor. But for his livelihood he had for a long time to depend upon concerts, until a propitious circumstance opened a new avenue for the exercise of his talents. Meantime he had experienced a new revelation. His genius had been brought into contact with that of Joseph Haydn, whom he met personally at the imperial palace in 1781 during the festivities occasioned by the visit of Grand Duke Paul of Prussia.[44] This master’s works now became the subject of his profound study, which bore almost immediate results in his instrumental works.

The propitious circumstance alluded to above lay in another direction. Joseph II had made himself the protector of the German drama in Vienna and had given the theatre a national significance. His patriotic convictions induced him to adopt a similar course with the opera, though his own personal tastes lay clearly in the direction of Italy. At any rate, he abolished the costly spectacular ballet and Italian opera and instituted in their stead a ‘national vaudeville,’ as the German opera was called. The theatre was opened in February, 1778, with a little operetta, Die Bergknappen, by Umlauf, and this was followed by a number of operas partly translated from the Italian or French, including Röschen und Colas by Monsigny, Lucile, Silvain, and Der Hausfreund by Grétry; and Anton und Antonette by Gossec. In 1781 the emperor commissioned Mozart to contribute to the repertoire a singspiel, and a suitable libretto was found in Die Enführung aus dem Serail. It had an extraordinary success. In the flush of his triumph Mozart married Constanze Weber, sister of the singer Aloysia Weber, the erstwhile sweetheart of Mannheim. This again complicated his financial circumstances; for his wife, loyal as she was, knew nothing of household economy. Not until 1787 did Mozart secure a permanent situation at the imperial court, and then with a salary of only eight hundred florins (four hundred dollars), ‘too much for what I do, too little for what I could do,’ as he wrote across his first receipt. His duties consisted in providing dance music for the court! Gluck died in the year of Mozart’s appointment, but his position with two thousand florins was not offered to Mozart. To the end of his days he had to endure pecuniary difficulties and even misery.

Intrigue of Italian colleagues, with Salieri, Gluck’s pupil, at their head, moreover placed constant difficulties in Mozart’s way, and when, in 1785, his ‘Marriage of Figaro’ was brought out in Vienna it came near being a total failure because of the purposely bad work of the Italian singers. But at Prague, shortly after, the opera aroused the greatest enthusiasm, and out of gratitude Mozart wrote his next opera, Don Giovanni, for that city (1787). In Vienna again it met with no success. In this same wonderful year he completed, within the course of six weeks, the three last and greatest of his symphonies.

In a large measure the composer’s own character—his simple, childlike and loyal nature—stood in the way of his material success. When, in 1789, he undertook a journey to Berlin with Prince Lichnowsky Frederick William II offered him the place of royal kapellmeister with a salary of three thousand thalers. But his patriotism would not allow him to accept it in spite of his straitened circumstances; and when, after his return, he was induced to submit his resignation to the emperor, so that, like Haydn, he might seek his fortune abroad, he allowed his sentiment to get the better of him at the mere suggestion of imperial regret. The only reward for his loyalty was an order for another opera. This was Così fan tutte, performed in 1790.
