The young musician had, indeed, no lack of work before him, for, in addition to the regular performances which formed the chief business of the tour, he was set difficult problems to solve at sight by the various professors who desired to test his powers. The fame of his playing preceded him everywhere, so that the further they penetrated into Italy the more numerous became the demands to hear him. At Roveredo, where it was announced that he would play the organ at St. Thomas's Church, the crowd was so great that the monks of the adjoining monastery had to form a circle around Mozart to keep back the press until the steps leading to the organ-loft had been gained. The vast audience listened spellbound to the performance, and then refused to disperse until they had gained a glimpse of the boy-player. At Verona, where another triumph awaited him, and where one of his symphonies was performed, the Receiver-General ordered his portrait to be painted, and wrote a letter to the mother full of warm praise of her wonderful son.
On reaching Milan the chief musician of the city subjected Mozart to the severest tests, from which he emerged victorious, and after astonishing everybody by his playing and improvisation, he was commissioned to write an opera for the ensuing season. It was at Bologna, however, that he met with the most flattering reception. The city contained many artists of the highest rank, over whom Padre Martini, the famous composer of Church music and the first connoisseur of the country, reigned like a king. Martini was, in fact, worshipped by Italian lovers of the art, who deferred to his opinion in all questions affecting music. But the Padre was very old, and had given up attending concerts, so that every one was astonished when the coming of Mozart brought the aged musician from his retirement to form one of the brilliant gathering assembled at Count Pallavicini's mansion to witness the boy's playing. It was a great compliment to Mozart, but an even greater compliment to the country from which he came, and Wolfgang put forth his best powers, with the result that he earned the judge's warmly expressed commendation. Leopold was overjoyed at Wolfgang's success, and opined that Bologna would form a centre from which the boy's fame would spread all over Italy, an opinion that was justified by the results. As for Martini, he took to Wolfgang at once, insisted that he should visit him regularly whilst they remained in Milan, and gave him fugue subjects to work out at his lodgings. Mozart worked hard at these tasks, and the Padre expressed himself as perfectly satisfied with the boy's knowledge of composition.
The journey to Rome, in fact, was a succession of triumphs, which it would require a volume by itself to attempt to describe in detail. At Florence he was invited to play before the Court of the Archduke Leopold, and solved, 'as easily as if he were eating a bit of bread,' the difficult problems proposed by the Court music-director, who was regarded as one of the best contrapuntists of the day. Here he met Thomas Linley, a boy of about his own age, the son of the English composer, who was studying the violin under Nardini. Linley's playing was already exciting much attention, and as he showed great promise in his compositions as well, people were building high hopes as to his future. Mozart and he instantly became close friends, and when the time came for parting neither could restrain his tears. They were destined never to meet again, for a few years later poor Linley was drowned through the upsetting of a boat whilst on a pleasure excursion in Lincolnshire. Mozart never forgot the bright friendship which had flashed into his life during those few days spent at Florence, and many years afterwards he would refer in terms of endearment to the young genius whose career had been thus untimely cut off.
It was Holy Week when Mozart and his father reached Rome, and the city lay under the spell of that solemn time. The travellers at once bent their steps to the Sistine Chapel in order to hear the celebrated Miserere, written by Allegri, performed. Wolfgang had been looking forward to this moment during the latter stages of his journey with the deepest interest. He had heard from his father of the jealous guarding of this wonderful work by the Romans; how it was expressly forbidden to be performed in any other building than the Sistine; and how the choristers were under strict injunctions not to remove their parts of the score from the chapel. His anxiety, therefore, to hear a work of which the fame had spread throughout the whole of Europe, had hastened his progress to the Holy City.
It would, indeed, be difficult to imagine anything more beautiful and impressive than the singing of this wonderful Miserere.[12] It is introduced into the solemn service called 'Tenebræ' (Darkness), during which the six tall altar candles, by which the chapel is illuminated, are extinguished one by one, until only a single candle is left, and this is removed to a space behind the altar. Then, in almost complete darkness, the Miserere begins. A single voice is heard singing the beautiful antiphon, as the short piece which ushers in the Miserere is called; the sweet notes die away into silence—a silence so profound that the listener hardly dares to breathe lest he should disturb it. Then at length the first sad notes of the Supplication are heard, like the softest wailing of an anguished spirit; they gradually increase in force until the whole building is ringing with the plaintive melody in all its thrilling intensity.
The solemnity of the service and the beauty of the music left a deep impression on the mind of the young musician who heard it for the first time. Leopold Mozart, too, was greatly affected by what he had heard, and when they left the chapel to seek their lodgings neither of them spoke a word. Once within doors, however, Wolfgang asked for pen and paper, and, sitting down there and then, he wrote out the whole of the Miserere from memory. On Good Friday, when the work was to be performed for the second time, he took his copy with him to the Sistine, and, concealing it in his cocked hat, he made one or two corrections in pencil as the service proceeded. It was not long before the news of this extraordinary feat reached the ears of the Papal musicians, and Wolfgang received orders to perform his version in the presence of Christoforo, the principal soprano of the Sistine, who could not conceal his amazement at finding it correct in every particular.
No better introduction than this was needed to secure for Mozart a cordial welcome at the houses of the great, and during their stay in Rome they were fêted to their hearts' content.
At Naples, which was their next stopping-place, Wolfgang played at the Conservatorio alla Pietà before a brilliant gathering, and excited so much astonishment that several of the audience openly declared that his powers were derived from a ring which he wore upon his finger. 'He wears a charm!' they cried; and when Mozart, hearing their remarks, smilingly laid aside the supposed magic ring, and played even more brilliantly than before, the enthusiasm was redoubled. After this the Neapolitans vied with one another to show them honour and attention. A carriage was provided for their use, in which they drove about amongst the fashionable crowds on the Strada Nuova and the quay, on which occasions Leopold wore a maroon-coloured coat of watered silk, with sky-blue facings, and Wolfgang one of apple-green, with rose-coloured facings and silver buttons.
We have not space, however, in which to describe all the events of Mozart's wonderful tour, and so we may only mention how they returned to Rome at the instance of the Pope, who not only granted Wolfgang a private audience, but bestowed upon him the Order of the Golden Spur, thus entitling him to be styled 'Signor Cavaliere Amadeo'; how, when next he wrote to Marianne, he jokingly concluded his letter as follows: 'Mademoiselle, j'ai l'honneur d'être votre très-humble serviteur et frère, Chevalier de Mozart'; and how his portrait was once more painted in Rome by Battoni. A still greater distinction was conferred upon him on his arrival at Bologna, for the Accademia Filarmonica admitted him to their ranks as 'compositore,' notwithstanding that their statutes required that members should be at least twenty years of age. To test his qualifications for election he was given an antiphon to set in four parts, and locked up in a room to fulfil his task. At the expiration of half an hour he asked to be let out, to the astonishment of the officials, who could scarcely credit that he had completed the work in so short a time. The composition was then examined by the professors, who next voted upon it, and finally, amidst clapping of hands, it was declared that Mozart had been duly elected.
After some further intercourse with Padre Martini, who, before leaving, presented Mozart with a testimonial, the travellers proceeded to Milan, where Wolfgang set to work at once on the opera which he had been commissioned to write. It was a great task, and we find him writing to his mother and sister, begging them to pray for its success, 'so that they may all live happily together again,' 'Mitridate,' as the work was called, was at length finished, after three months' hard labour, some of which was devoted to fighting the opposition emanating from both singers and rivals. The first performance took place on December 26, 1770, and was conducted by Wolfgang, whose appearance in the orchestra was the signal for a great outburst of cheering, to be repeated again and again as the opera proceeded. Then came loud cries of 'Evviva il Maestro! Evviva il Maestrino!' in response to which Mozart gravely bowed his acknowledgments, and at the same time bent his glance towards the spot where his father sat with his eyes covered with his hand, in order to hide the tears of pride and joy which filled them to overflowing. Mingled with these feelings, however, Leopold felt a deep thankfulness in his heart that he had been spared to watch over his son's career, and to be a witness of his success.
