Chopin's long-projected and much-desired visit to Berlin came about in this way. In 1828 Frederick William III of Prussia requested the Berlin University to invite the most eminent natural philosophers to take part in a congress to be held in that city under the presidency of Alexander von Humboldt. Nicholas Chopin's friend Dr. Jarocki, the zoologist and professor at the Warsaw University, who had studied and obtained his degree at Berlin, was one of those who were honoured with an invitation. The favourable opportunity which thus presented itself to the young musician of visiting in good company one of the centres of civilisation—for the professor intended to comply with the invitation, and was willing to take his friend's son under his wing—was not allowed to slip by, on the contrary, was seized eagerly. With what feelings, with what an infinitude of youthful hopes and expectations, Chopin looked forward to this journey may be gathered from some expressions in a letter of his (September 9, 1828) addressed to Titus Woyciechowski, where he describes himself as being at the time of writing "like a madman," and accounts for his madness by the announcement: "For I am going to-day to Berlin." To appear in public as a pianist or composer was not one of the objects he had in view. His dearest wishes were to make the acquaintance of the musical celebrities of Berlin, and to hear some really good music. From a promised performance of Spontini's Ferdinand Cortez he anticipated great things.

Professor Jarocki and Chopin left Warsaw on the 9th of September, 1828, and after five days' posting arrived in Berlin, where they put up at the Kronprinz. Among the conveniences of this hotel our friend had the pleasant surprise of finding a good grand piano. He played on it every day, and was rewarded for his pains not only by the pleasure it gave him, but also by the admiration of the landlord. Through his travelling companion's friend and teacher, M. H. K. Lichtenstein, professor of zoology and director of the Zoological Museum, who was a member of the Singakademie and on good terms with Zelter, the conductor of that society, he hoped to be made acquainted with the most distinguished musicians of the Prussian capital, and looked to Prince Radziwill for an introduction to the musical autocrat Spontini, with whom Lichtenstein was not on a friendly footing. In these hopes, however, Chopin was disappointed, and had to content himself with looking at the stars from afar. Speaking of a performance of the Singakademie at which he was present, he says:—

Spontini, Zelter, and Felix Mendelssohn-Bartholdy were also
there; but I spoke to none of these gentlemen, as I did not
think it becoming to introduce myself.

It is not difficult to discover the circumstances that in this respect caused matters to turn out so little in accordance with the young man's wishes. Prince Radziwill was not in Berlin when Chopin arrived, and, although he was expected, perhaps never came, or came too late to be of any use. As to Lichtenstein, his time was too much taken up by his duties as secretary to the congress. Had this not been so, the professor could not only have brought the young artist in contact with many of the musical celebrities in Berlin, but also have told him much about his intimate friend Carl Maria von Weber, who had died little more than two years before. Lichtenstein's connection with Weber was probably the cause of his disagreement with Spontini, alluded to by Chopin. The latter relates in an off-hand way that he was introduced to and exchanged a few words with the editor of the Berliner Musikzeitung, without mentioning that this was Marx. The great theorist had of course then still to make his reputation.

One cannot help wondering at the absence from Chopin's Berlin letters of the name of Ludwig Berger, who, no doubt, like Bernhard Klein, Rungenhagen, the brothers Ganz, and many another composer and virtuoso in Berlin, was included in the collective expression "distinguished musicians." But one would have thought that the personality of the pupil of Clementi, the companion of A. Klengel, the friend of Steibelt, Field, and Crotch, and the teacher of Mendelssohn and Taubert, would have particularly interested a young pianist. Berger's compositions cannot have been unknown to Chopin, who, moreover, must have heard of him from his Warsaw acquaintance Ernemann. However, be this as it may, our friend was more fortunate as regards hearing good music, which certainly was a more important business than interviewing celebrities, often, alas, so refrigerating in its effect on enthusiastic natures. Before his departure from Warsaw Chopin wrote:—"It is much to hear a really good opera, were it only once; it enables one to form an idea of what a perfect performance is like." Although the most famous singers were on leave of absence, he greatly enjoyed the performances of Spontini's "Ferdinand Cortez", Cimarosa's "Die heimliche Eke" ("Il Matrimonio segreto"), Onslow's "Der Hausirer" ("Le colporteur"), and Winter's "Das unterbrochene Opferfest." Still, they gave rise to some "buts," which he thought would be wholly silenced only in Paris; nay, one of the two singers he liked best, Fraulein von Schatzel (Signora Tibaldi was the other), reminded him by her omissions of chromatic scales even of Warsaw. What, however, affected him more than anything else was Handel's "Ode on St. Cecilia's Day," which he heard at the Singakademie; it came nearest, he said, to the ideal of sublime music which he harboured in his soul. A propos of another musical event he writes:—

To-morrow the "Freischutz" will be performed; this is the
fulfilment of my most ardent wish. When I hear it I shall be
able to make a comparison between the singers here and our
own.

The "Freischutz" made its first appearance on the Warsaw stage in 1826, and therefore was known to Chopin; whereas the other operas were either unknown to him or were not considered decisive tests.

Music and things connected with music, such as music-shops and pianoforte-manufactories, took up Chopin's attention almost exclusively. He declines with thanks the offer of a ticket for the meetings of the congress:—

I should gain little or nothing for my mind from these
discussions, because I am too little of a savant; and,
moreover, the professional gentlemen might perhaps look at
me, the layman, and think: "How comes Saul among the
prophets?"

Of the Royal Library, to which he went with Professor Jarocki, he has no more to say than that "it is very large, but contains few musical works"; and when he visits the Zoological Museum, he thinks all the time what a bore it is, and how he would rather be at Schlesinger's, the best music-shop in the town, and an enterprising publishing house. That he neglects many things which educated men generally prize, he feels himself, and expresses the fear that his father will reproach him with one-sidedness. In his excuse he says:—
