Mozart now thought seriously of a journey to London and Paris, but his father's urgent appeal that he would wait and exercise patience, delayed him. Meanwhile he carried out an ardent desire to pay a visit to his father and sister in Salzburg, to present to them his bride. It was a very happy visit, and later on, when Mozart and his wife were again settled in Vienna, they welcomed the father on a return visit. Leopold found his son immersed in work, and it gladdened his heart to see the appreciation in which his playing and compositions were held. One happy evening they spent with Josef Haydn who, after hearing some of Mozart's quartets played, took the father aside, saying: "I declare before God, as a man of honor, that your son is the greatest composer I know, either personally or by reputation. He has taste, but more than that the most consummate knowledge of the art of composition."
This happy time was to be the last meeting between father and son. Soon after Leopold's return to Salzburg, he was stricken with illness, and passed away May 28, 1787. The news reached the composer shortly after he had achieved one of the greatest successes of his life. The performances of his latest opera, "The Marriage of Figaro," had been hailed with delight by enthusiastic crowds in Vienna and Prague; its songs were heard at every street corner, and village ale house. "Never was anything more complete than the triumph of Mozart and his 'Nozze di Figaro,'" wrote a singer and friend.—"And for Mozart himself, I shall never forget his face when lighted up with the glowing rays of genius; it is as impossible to describe as to paint sunbeams."
Despite the success of Figaro, Mozart was still a poor man, and must earn his bread by giving music lessons. Finally the Emperor, hoping to keep him in Germany, appointed him Chamber-composer at a salary of about eighty pounds a year. It must have seemed to Mozart and his friends a beggarly sum for the value his Majesty professed to set upon the composer's services to art. "Too much for the little I am asked to produce, too little for what I could produce," were the bitter words he penned on the official return stating the amount of his salary.
Mozart was inclined to be somewhat extravagant in dress and household expenditure, also very generous to any one who needed assistance. These trials, added to the fact that his wife was frequently in ill health, and not very economical, served to keep the family in continual straits. Occasionally they were even without fire or food, though friends always assisted such dire distress. Mozart's father had declared procrastination was his son's besetting sin. Yet the son was a tireless worker, never idle. In September, 1787, he was at Prague, writing the score of his greatest opera, "Don Giovanni"; the time was short, as the work was to be produced October 29. On the evening of the 28th it was found he had not yet written the overture. It only had to be written down, for this wonderful genius had the music quite complete in his head. He set to work, while his wife read fairy tales aloud to keep him awake, and gave him strong punch at intervals. By seven o'clock next morning the score was ready for the copyist. It was played in the evening without rehearsal, with the ink scarcely dry on the paper.
Even the successes of "Don Giovanni," which was received with thunders of applause, failed to remedy his desperate financial straits. Shortly after this his pupil and patron, Prince Karl Lichnowsky, proposed he should accompany him to Berlin. Mozart gladly consented, hoping for some betterment to his fortunes. The King of Prussia received him with honor and respect and offered him the post of Capellmeister, at a salary equal to about three thousand dollars. This sum would have liberated him from all his financial embarrassments, and he was strongly tempted to accept. But loyalty to his good Emperor Josef caused him to decline the offer.
The month of July, 1791, found Mozart at home in Vienna at work on a magic opera to help his friend Salieri, who had taken a little theater in the suburb of Wieden. One day he was visited by a stranger, a tall man, who said he came to commission Mozart to compose a Requiem. He would neither give his own name nor that of the person who had sent him.
Mozart was somewhat depressed by this mysterious commission; however he set to work on the Requiem at once. The composing of both this and the fairy opera was suddenly interrupted by a pressing request that he would write an opera for the coronation of Leopold II at Prague. The ceremony was fixed for September 6, so no time was to be lost. Mozart set out at once for Prague. The traveling carriage was at the door. As he was about to enter it, the mysterious stranger suddenly appeared and enquired for the Requiem. The composer could only promise to finish on his return, when hastily entering his carriage, he drove away.
The new opera, "La Clemenza di Tito," was finished in time and performed, but was received somewhat indifferently. Mozart returned to Vienna with spirits depressed and body exhausted by overwork. However, he braced himself anew, and on September 30th, the new fairy opera, the "Magic Flute," was produced, and its success increased with each performance.
The Requiem was not yet finished and to this work Mozart now turned. But the strain and excitement he had undergone for the past few months had done their work: a succession of fainting spells overcame him, and the marvelous powers which had always been his seemed no longer at his command. He feared he would not live to complete the work. "It is for myself I am writing the Requiem," he said sadly to Constanza, one day.
On the evening of December 4, friends who had gathered at his bedside, handed him, at his desire, the score of the Requiem, and, propped up by pillows he tried to sing one of the passages. The effort was too great; the manuscript slipped from his nerveless hand and he fell back speechless with emotion. A few hours later, on the morning of December 5, 1791, this great master of whom it was prophesied that he would cause all others to be forgotten, passed from the scene of his many struggles and greater triumphs.
