In two respects this work seems to the student different from the symphonic work of Beethoven on the one hand, and from the earnest orchestral work of later masters on the other. It is thoroughly modern in its thematic handling. Everything grows out of a very few central roots; yet out of these vital germs, as in the stories of Eastern magicians, a mighty tree forms itself before our very eyes. Or, to change the figure, while the actual melodic germ is very small, its development into the leading subject takes it over a considerable range of rhythm and harmony, and brings it to us with almost a song-like character. Then, when we come to a second subject, it is not so completely contrasted as in Beethoven; or, rather, it still partakes of the modern spirit, being, if very legato, nevertheless very appealing and earnest in its harmonic treatment. This is one point where Beethoven always did differently, for his second subjects are almost invariably simple and lyric, with something very like a folk-song turn of melody. Brahms remains upon the elevated plane of musical earnestness which he assumes at starting, and throughout the entire work carries us ever to greater heights.
Again, from the side of tone-color Brahms differs from later writers in not giving himself much to mere lusciousness of tone contrast, but confines himself to carrying out his ideas with those portions of the orchestra best suited in turn, and with more reference to cumulative impression from the treatment than to mere richness and contrast of color. The contrasts do still meet us here, but they are never glaring. It is even a question whether the colors are so strongly contrasted as commonly in Beethoven. But it is not a question whether the music is strong, meaningful, and musicianly. These qualities are patent to even a casual hearing. Equally recognizable is that inner something which has been called the ethical element; a something in the general spirit of treatment, or behind it, which we intuitively feel as consistent with our highest thoughts, noblest moods, and best resolutions. This is distinguished from the merely sensuous, as represented sometimes in Berlioz, Goldmark, Gounod, and the like; and the fantastic, inconsequent, and irresponsible, as represented, for instance, in Richard Strauss' "Till Eulenspiegel."
The second movement, andante moderate, although very strange in certain of its peculiarities, is nevertheless very beautiful, and at the same time novel. The subject is given out first by the horn alone; afterward it is taken up by the oboes and flutes, while the strings have a secondary place and complete the harmony.
Kretschmar says that it reminds one of a story of the olden time, an impression due to the archaic tonality, the first version of the theme being in the Gregorian Phrygian mode—a key of E in which all the notes are naturals. On its repetition it is given a different turn, the scale having a major seventh, but minor third and sixth.
Kretschmar says: "In the middle of this movement, where the triplets begin, the music forsakes this neutral tone and shows a friendly spirit and breaks out into heart-felt lamentations." In other words, a subordinate subject is introduced which Mr. Apthorp characterizes (in the Boston Symphony Orchestra programs) as "a grave, solemn melody, harmonized and scored in the richest coloring."
A third melodic idea still remains to be mentioned. It is the melody for 'cello, which is delicately accompanied by the higher strings. Later the first subject returns in a variety of treatment, always cumulative in its character, and frequently with strange transformations. The impression of the whole is, after all, that already mentioned; it is a story of the olden times, into which a modern thread has been woven, and through which the modern heart still thrills and vibrates none the less powerfully for the strange-sounding accents of the ancient tonality.
The third movement, allegro giocoso (giocoso primarily means jokingly), opens with full orchestra. This movement takes the place of a scherzo. It is earnest, vigorous, and free; at times, as Mr. Apthorp says, "almost fierce"; and for straightforward directness stands in manly contrast to the movements preceding.
The fourth movement, again, is marked allegro energico epassionato (quick, energetically, and passionately). It opens with eight measures for all the brass. The melody lies in the upper voice.
Upon this as cantus firmus Brahms has developed what is known as a passacaglia; originally a rather slow and stately dance, but in musical use denoting a movement developed over a ground bass, or single harmonic foundation, the final result partaking somewhat of the nature of variations; but more of a sort of cumulative playing with musical elements, finally reaching a great degree of complexity, which, if well done, should also be a complexity of idea and a fullness and richness of expression. It was in this spirit that Bach handled the form in his great C minor Passacaglia for organ, now transcribed for orchestra, and played occasionally, if I remember, by Mr. Thomas; and it is in this spirit that Brahms works here. Occasionally the spirit changes to something tender, meditative; but this is only to gain strength. Immediately it resumes, and is carried ever and ever to higher pitches of force and meaning. Melody after melody appears in prominent places, but under every one lies the harmonic foundation of the fundamental subject. There are thirty-two of these variations in all.
The criticism which has been made upon Brahms, that a movement of this kind has no proper place in symphony, is "not competent," as lawyers say; for, setting aside the demonstrated fact that Brahms knew better what could be done in symphony than any of his critics, there is plenty of precedent for doing almost anything one cares to try in the fourth movement of a symphony. The old practice had a rondo for the final movement of the sonata. Beethoven rightly felt the insignificance of this form and its half trivial spirit, and in many directions he sought to get out of it, and to end his sonatas with a climax of the spiritual interest. The same desire is shown in his symphonies and chamber music. Brahms has here given us a manly, vigorous, strongly developed piece. At least, it closes the symphony without loss of vitality—whether with increasing elevation of spiritual meaning is for each hearer to determine according to the measure of his capacity and receptive ness. Inspiration is not a question of light being ready, but of clear glass to shine through.
