Notwithstanding the stringent rules as to punctuality of attendance inserted in this formal document, the meetings were seriously interrupted during the season, and by the absence of no less a person than the director himself. Johannes could in no case, especially in his present restless mood, have remained away from the Rhine Festival of the year (Düsseldorf, May 27-29). Schumann's B flat Symphony was to be performed, Hiller to conduct, Joachim to play the Hungarian Concerto and a Beethoven Romance, and Stockhausen to sing selections by Boieldieu, Schubert, Schumann, and Hiller. Frau Schumann was to attend the concerts, and expected to meet many intimate friends at Düsseldorf, amongst them being Dietrich and his bride, a lady long known to the circle as Clara Sohn, daughter of the painter and professor at the Art Academy. Brahms therefore accompanied Frau Schumann and her daughter when they left Hamburg for Düsseldorf on May 24, and the occasion of the festival proved no less enjoyable than those similar ones which have been referred to in our pages. A new feature at one or more of the private reunions that took place in the intervals of the concerts was the singing of quartets, under Brahms' direction, by four members of the Ladies' Choir who had come to the Festival: the sisters Fräulein Betty and Fräulein Marie Völckers, Fräulein Laura Garbe, and—Frau Schumann herself. She, indeed, it was who proposed to her hostess, Fräulein Leser, that the Dietrichs, Joachim, Stockhausen, and a few others, should be invited to listen to what proved a delightful performance.

Under the circumstances, it cannot be regarded as surprising that Brahms did not immediately return to Hamburg after the festival, but made one of a party that proceeded to Bonn, where he remained with his companions till towards the middle of July.

'The spring had set in gloriously,' says Dietrich, who, as the reader will remember, had been settled for some years in the city. 'There is something enchanting in such a spring on the Rhine. The pink blossoming woods of fruit-trees, the numerous whitethorn hedges on the banks of the river, the voices of nightingales in the light, warm nights, the fine outlines of the Siebengebirge in the distance; what excursions we were induced to make! It was a happy, sunny time, rich also in artistic enjoyment.

'For Brahms, after six years' long silence, had brought with him a number of splendid compositions. There were the two serenades, the Ave Maria, the Begräbnissgesang, Songs and Romances, and the Concerto in D minor.

'He had employed his retirement in the most earnest studies; he had composed, amongst other things, a Mass in canon form, which, however, has not been printed.

'We met frequently at the Kyllmanns' hospitable and artistic house for performances of chamber music and the enjoyment of Stockhausen's splendid singing.

'The artists came also often and gladly to our young home, and before we parted they were present with us at the baptism of our first child. Brahms, Joachim, and Heinrich von Sahr were the sponsors.'[90]

Herr Kyllmann's house in Coblenzstrasse, with its beautiful garden situated on the Rhine bank and commanding a view of the Siebengebirge, was the scene of many noteworthy reunions that gave equal pleasure to the famous guests and the art-loving, art-appreciating family, who were proud to entertain them. One party which took place early in June, during the week that Frau Schumann was able to remain amongst her friends, must be recorded in detail, for the musical performances included a string quartet played by Joachim, David, Otto von Königslow (for many years concertmeister of the Gürzenich subscription concerts, Cologne), and the excellent 'cellist Christian Reimers; Schumann's Quintet, by the same artists, with Frau Schumann as pianist; and songs sung by Stockhausen to Frau Schumann's accompaniment—amongst them 'Mondnacht' and 'Frühlingsnacht.' Otto Jahn, who was, of course, present to enjoy the music, brought with him his friend Dr. Becker, just arrived from England on his resignation of his post of private secretary to the Prince Consort, and Brahms must be counted with them amongst the listeners. He retired to the sofa of an inner drawing-room, and was not to be induced to perform, though Frau Schumann herself came to request him to do so, and Joachim followed with his persuasive 'Oh, Johannes, do play!' Johannes, as is abundantly evident, was no diplomatist. He often felt it easier to know himself misunderstood than to overcome his nervous shrinking from the ordeal of sitting down to play before a mixed party of listeners.

The nearly two months passed at Bonn, during which Johannes and Joachim lodged respectively at 29 and 27, Meckenheimerstrasse, proved of importance in Brahms' career. It was at this time that he made the acquaintance of Herr Fritz Simrock, a young man about his own age, junior partner in the well-known publishing house of N. Simrock at Bonn, and destined, as the later head of the firm after the removal to Berlin, to usher into the world the great majority of the composer's works. Between Fritz Simrock and Brahms a cordial understanding gradually established itself; the publisher's dealings with the musician were from the first considerate and generous, and when Brahms' fortunes became flourishing, it was Simrock who was his confidant and adviser in business matters. As an earnest of the future, the Serenade in A, Op. 16, was published by the firm before the close of the year, the Serenade in D, Op. 11, being issued in the autumn by Breitkopf and Härtel. The Pianoforte Concerto, refused by this firm, was accepted by Rieter-Biedermann, together with the 'Ave Maria,' Begräbnissgesang, and the Lieder und Romanzen (Op. 14), all of which were published the following year.[91]

'I am very glad to see Johannes' things in print before me at last,' wrote Joachim to Avé Lallement. 'Now the Signale and other superficial papers may abuse them as they please. We have done right. They will continue to smile on with their beautiful motifs long after the clumsy fault-finders have been silenced.'
