=Journey to Paris=.—Returning to Salzburg, Mozart took up the post previously given him of music director to the Archbishop; but his emolument, at first wholly wanting, was insignificant, and the Archbishop, having little appreciation of his abilities, proved a thankless taskmaster. During this time he made several journeys to Milan, producing new dramatic works there; and in 1777, as his Salzburg position had become intolerable, he resolved to give it up, and to repair to Paris. Starting on this journey with his mother, he stopped at Munich, and then at Augsburg, where he became interested in the Stein pianofortes, henceforth adopting them for his concert work. At Mannheim he heard the famous orchestra, of which Stamitz was the founder, whose command of instrumental brilliancy and color made so powerful an impression upon him that he transmitted it to his succeeding orchestral compositions. [Illustration: WOLFGANG AMADEUS MOZART.] =“Idomeneo” and “Il Seraglio.”=—At Paris, he found society divided into two warring operatic factions, led by Gluck and Piccini, and averse to anything else in music. Saddened also by the death of his mother, he returned to Salzburg, and resumed his former post with the Archbishop. Receiving an order to write an opera for the Carnival at Munich, he produced his “Idomeneo” there in 1781. Shortly after, he was compelled, through ill-treatment, to break finally with the Archbishop, and he resolved to settle in Vienna. In the same year, 1782, in which he produced there his opera, “Entführung aus dem Serail,” composed by command of the Emperor, he married Constance Weber. =Financial Troubles=.—His life from this time was a constant struggle against poverty; for notwithstanding his wonderful genius, he received only scant recognition from his patron, the Emperor, although loyal to him to the end. His existence was eked out chiefly by the sale of his compositions, which publishers purchased at a low price, by giving lessons and by playing at concerts; while the jealousy of rivals furnished a constant source of annoyance. =“Figaro,” “Don Giovanni” and Symphonies=.—His comic opera, “The Marriage of Figaro,” produced in Vienna in 1786, came near failing through these enemies, but was an unqualified success in Prague, where, in the following year, his masterpiece, “Don Giovanni,” was produced. On a concert tour in 1786 he was offered an excellent post in the service of King Frederic Wilhelm II, of Prussia, which he refused, through loyalty to his Emperor—a devotion which received no reward save an order to write another opera. In the same year, 1789, his three most important symphonies were completed—the “Jupiter,” in C, and those in G minor and E-flat major.
