“That Brahms initially approached the symphonic form with trepidation is fairly evident from the chronology of his works. It wasn't until the age of 43 that he completed his First Symphony. Indeed, the composer’s output to that point suggests a conscious process of self-education. A number of smaller-scale orchestral works, including the Variations on a Theme of Haydn and the proto-symphonic Piano Concerto No. 1, suggest preparation for what Brahms clearly saw as the elusive of compositional enterprises. He was to meet the challenge with a skill and individual spirit, one of Classicism refracted through the prism of high omanticism, that led many to pronounce him heir to Beethoven” (Rodman).
“Each of the movements bears the distinct stamp of the composer’s personality. The first begins with a theme in E minor based upon the interval of a third, which also provides a structural and motivic foundation for the remainder of the work. There is a notable sense of unrest from beginning to end, and the tragic, even fatalistic atmosphere is further and stunningly underlined by the final, minor-key plagal (IV-I) cadence. The second movement, which opens with a brief, melancholy sort of fanfare, gives way to the quietly accompanied winds in perhaps one of the loveliest of any of the composer’s themes, granted particular plangency through the use of the flat sixth and seventh scale degrees borrowed from the minor mode. This material is gradually developed into soaring, tutti lyricism that fades into ethereal quiet. The third movement, a lusty, stomping, duple dance, proved so popular in Brahms’ lifetime that audiences constantly demanded that it be repeated. The last movement is perhaps most notable of all, cast as it is in the "archaic" Baroque form of a chaconne — variations over a ground bass. The chaconne’s subject is in fact a slight modification of that used by Bach in his Cantata No. 150; though deceptively simple — essentially an ascending minor scale segment from the tonic note to the dominant, then a leap back to the tonic — Brahms uses this skeleton as the basis for an increasingly elaborate and thematic harmonic framework. From its first presentation, which is not as a bass line, but as a theme in the winds, Brahms gradually weaves some 34 variations that steadily build in intensity, as though in defiance to the oppressive, insistent rotation of the ground. The final variations lead directly into an ending which reconfirms the weight of tragedy and pathos borne by the first movement” (Rodman).
