Goethe wrote his cantata expressly that music might be set to it by Capellmeister Winter, a respectable musician of his day, for the Prince Friedrich of Gotha, the possessor of an agreeable tenor voice, and a good amateur vocalist. It is founded on an episode in Tasso's 'Jerusalem Delivered,' and exhibits the conflict between weakness and strength in the brave knight Rinaldo—a fictitious personage introduced into his poem by Tasso—who is roused from his surrender to the witcheries of Armida by the arrival, at the islet on which he is living with her, of a party of knights, his friends—two only in Tasso's epic, but increased to a chorus by Goethe. The cantata opens at a point where the knights have succeeded in awakening Rinaldo from his dream of happiness, but are unable to nerve him to the resolution of departure. As a final resource, they hold up before him a diamond shield, which reflects his own image in its degeneracy. The shock of what he sees restores him to full consciousness, and he leaves the island in spite of Armida's lamentations, fury, and enchantments, and his own regrets, encouraged and supported by his friends. The final chorus with solo depicts the happy return voyage, and the safe arrival of the ship at the shore of the Holy Land.

Armida does not appear as a dramatis persona in Goethe's work, and Brahms' music is accordingly composed for tenor solo, men's chorus, and orchestra. The poem is short and concise, containing but one dramatic situation, but its very terseness has been advantageous to the composer, for the text has not fettered his imagination by detail, whilst it has supplied him with sufficient material for powerful and contrasted musical presentation in the enchantments of Armida, the storm raised by her to prevent the ship's departure, the calm, persuasive firmness of the knights, the vacillation of Rinaldo (expressed in the first instance in an impassioned scena), his pleadings with his friends, his final awakening and recovery from the intensity of passion. Of all these points Brahms has availed himself with force and warmth of imagination. Many interesting details of the composition tempt our notice, but we may only stay to direct the reader's attention to the conviction inspired by the choruses of the noble, lovable character of the knights; to the masterly means employed—so simple that only a master would have ventured to restrict himself to them—at the moment when the shield is displayed, which, in their place, convey, without any attempt at tone-painting, but with absolute distinctness, the impression of the friends' gentle determination with the shrinking Rinaldo; to the bright martial movement in which the knights encourage him by reminding him of the flashing lances, the waving pennons, the whole brilliant battle array, of the crusaders' army from which the allurements of Armida have too long detained him. In the final chorus a favourable wind swells the sails of the ship, which rides joyously over the green waves, breaking them into light foam as she passes, whilst Rinaldo and his companions amuse themselves by watching the dolphins at play in the water, and are filled with a light-hearted happiness that, as land is sighted, bursts into exultant shouting of the names of Godfrey and Solyma (Jerusalem).

The work was performed for the first time from the manuscript, under the composer's direction, on February 28, 1869, at a concert of the Akademischer Gesangverein, Vienna. The title-part was sung with great success by Gustav Walter, three hundred students well prepared by Dr. Eyrich, the society's conductor, were responsible for the choruses, and the orchestral accompaniments were performed by the entire body of instrumentalists of the court opera.

A series of three concerts, given in Vienna in February and March by Brahms and Stockhausen were phenomenally successful. The great baritone had not been heard in the Austrian capital for many years, and all tickets for the first concert were sold immediately after its announcement. Brahms' selection for the series included works by Handel, Bach, Couperin, Gluck, Beethoven, Schubert, Schumann, some of his own Variations—notably those of the B flat Sextet—and Hungarian Dances; and he accompanied his friend in many of the most celebrated songs of his répertoire. The wonderful performance by the two artists of Brahms' songs 'Von ewiger Liebe' and 'Mainacht' was one of the choice delights of the first concert. A feature of the second was the performance by Stockhausen and Fräulein Girzik of two of the composer's vocal duets. The enthusiasm excited by the concert-givers in Vienna was equalled in Budapest, whither they proceeded on March 10, in order to give a similar series; and it was, if possible, exceeded on their final reappearance in Vienna.

These concerts are of peculiar interest in Brahms' career, because the last of them closes the period of his activity as a virtuoso. For fourteen years, from the autumn of 1855 to the spring of 1869, circumstances had obliged, and happily permitted, him to earn his livelihood chiefly by the exercise of his powers as an executive artist; but his reputation as a composer had grown uninterruptedly throughout this time, and with the production of the German Requiem it attained a height that gave him future independence of action. Though years were still to pass before his circumstances became easy, they were not again straitened, and from henceforth he undertook concert-journeys only in the rôle of a composer, to assist at performances of his own works. The occasions on which he appeared additionally as pianist with one of Beethoven's or Schumann's great compositions became less and less frequent, moreover, as, with passing time, he felt increasingly out of regular practice. Brahms was, in later life, fond of illustrating the fact of his long struggle with poverty by referring to the manuscript of the Requiem. 'The paper is of all sizes and shapes, because at the time I wrote it I never had money enough to buy a stock.' The immediate impression created by the great work was, however, sufficiently widespread and profound to place the composer alone, among the musicians of his day, as the accepted representative of the classical art of Germany, and the prices commanded by his copyrights gradually increased accordingly. No long time elapsed before the German Requiem had made the round of the musical cities of Europe. It was given, for the first time after final completion and publication, at the Leipzig Gewandhaus concert of February 18, 1869, under Reinecke, and was performed in the course of the next few weeks in Basle (twice), Carlsruhe (twice), Münster, Cologne, Hamburg, Zürich, and Weimar, and, later in the year, in Dessau (twice), Chemnitz (twice), Barmen (four choruses only), Magdeburg, Jena, and again twice in Cologne. The complete work was not heard in Vienna until March 5, 1871, when it was given by the Gesellschaft der Musikfreunde under the composer's direction, with Frau Wilt and Dr. Krauss as soloists, but achieved no striking success. It was performed on July 7 of the same year (1871) for the first time in England, before an invited audience, at the residence of Sir Henry Thompson. Stockhausen conducted the rehearsals and performance, and sang the baritone solo, Fräulein Anna Regan the soprano solo. The chorus was composed of about thirty good musicians, and the accompaniments were played in their arrangement as a pianoforte duet by Lady Thompson and the veteran musician Cipriani Potter, then in his eightieth year. The first public performance in England which the author has been able to authenticate with precision is that of the Philharmonic Society in St. James's Hall on April 2, 1873, under the direction of W. G. Cusins, when the soloists were Mlle. Sophie Ferrari and Santley. The work was performed for the first time in Berlin, Munich and St. Petersburg in the spring, and in Utrecht in June, of the year 1872, and in Paris in 1874.[34]

Probably it was due to the impression created by the German Requiem that the Serenade in D, Op. 11, was performed for the first time in Berlin in November, 1869, at one of the concerts of the Symphony Orchestra under Capellmeister Stern.

'The reception showed that the public is beginning to understand and value the composer Brahms, one of the few living creative artists who are genuine and sincere,' wrote a Berlin critic.

In the earlier part of the same year Louis Brassin played the Handel Variations and Fugue in Munich with very great success. Brassin was one of the first artists to perform the work in public, and that he introduced it to a Munich audience is the more interesting since the musicians of the Bavarian capital had in 1869 shown scant, if any, recognition of our composer's art, which was too progressive for Franz Lachner, and too conservative for von Bülow, the successive leaders, up to that date, of the musical life of the city. The work was played by Bülow in November, 1872, in Carlsruhe, and from that time was heard at his concerts with increasing frequency.
