Haydn and Mozart were perfectly in accord, and each thought and did well toward the other. Mozart, we know, was born when Haydn had just reached manhood, so that when Mozart became old enough to study composition the earlier works of Haydn's chamber music had been written; and these undoubtedly formed the studies of the boy Mozart, and greatly influenced his style; so that Haydn was the model and, in a sense, the instructor of Mozart. Strange is it then to find, in after-years, the master borrowing (perhaps with interest!) from the pupil. Such, however, was the fact, as every amateur knows. At this we can hardly wonder, for Haydn possessed unbounded admiration not only for Mozart, but also for his music, which the following shows. Being asked by a friend at Prague to send him an opera, he replied: "With all my heart, if you desire to have it for yourself alone, but if you wish to perform it in public, I must be excused; for, being written specially for my company at the Esterhazy Palace, it would not produce the proper effect elsewhere. I would do a new score for your theatre; but what a hazardous step it would be to stand in comparison with Mozart! Oh, Mozart! If I could instill into the soul of every lover of music the admiration I have for his matchless works, all countries would seek to be possessed of so great a treasure. Let Prague keep him, ah! and well reward him, for without that the history of geniuses is bad; alas! we see so many noble minds crushed beneath adversity. Mozart is incomparable, and I am annoyed that he is unable to obtain any court appointment. Forgive me if I get excited when speaking of him, I am so fond of him." Mozart's admiration for Haydn's music, too, was very marked. He and Herr Kozeluch were one day listening to a composition of Haydn's which contained some bold modulations. Kozeluch thought them strange, and asked Mozart whether he would have written them. "I think not," smartly replied Mozart, "and for this reason: because they would not have occurred either to you or me!" On another occasion we find Mozart taking to task a Viennese professor of some celebrity, who used to experience great delight in turning to Haydn's compositions to find therein any evidence of the master's want of sound theoretical training--a quest in which the pedant occasionally succeeded. One day he came to Mozart with a great crime to unfold. Mozart as usual endeavored to turn the conversation, but the learned professor still went chattering on, till at last Mozart shut his mouth with the following pill: "Sir, if you and I were both melted down together, we should not furnish materials for one Haydn." It was one of the most beautiful friendships in the history of art; full of tender offices, and utterly free from the least taint of envy or selfishness. IV.
