Undoubtedly the most famous four notes in music, the opening “fate” motive of Beethoven’s 5th symphony sums up the entire work, providing the kernel from which the entire 30-minute piece is built. Aptly enough, Beethoven first states this kernel at the very beginning of the work, framed with dramatic fermatas that immediately draw the listener’s attention, to borrow a term, to “stare” at it, devoid of the context of meter or harmony.
Indeed, this kernel provides the rhythmic pulse of the entire piece. It appears at every stage in the first movement’s sonata-form structure, driving the forward through the constant fermatas. In the second and third movements, it appears as triplets, powering the driving Scherzo. Finally, as a low rumble in the timpani, it creates a bridge to the finale with its final blaze of C major. This “fateful” rhythm finds its apotheosis here, propelling the violins to the heights of glory in m. 6, and appearing again in triumphant triplets in m. 45.
Beethoven’s facility with limited material is manifest at every level, from overall structure to individual themes. The second movement, for instance, is built on short gestures, repeated until they become almost fragmentary. It takes him almost 20 measures to provide a consequent to the opening phrase. The main “theme” of the movement, too, is fragmentary, consisting of the opening melody, the closing gesture in m. 8, and the motive in 23. Beethoven then subjects these to variation, using the key of C major to provide a contrast in color and character and to disguise the simplicity of the process at work. A flat and C, third relations that mirror the Eb and C of the opening, are the only keys this movement actually moves through, and the three motives stated at the movement’s beginning are the only motivic material to appear over the course of the its 247 measures, other than gestures such as the E flat scale, which grow organically out of the process of variation, showing us, as it were, Beethoven exploring a particular sonority, or tinkering with motivic raw material.
Like the opening of the first movement, the symphony’s third movement also provides another glimpse of the composer at work, setting forth a motive and then pausing to think. As in every movement of this symphony, what follows comes entirely from the opening material, in various inversions and variations. The simple four-note horn theme, derived from the “fate” motive both in its rhythm and harmonic ambiguity, leads him through a series of keys within the space of a few bars. The trio, based completely on the fugue subject, uses even less material. A characteristically Beethoven gesture turns this masterful piece of craftsmanship into a stroke of genius as the final remains of the once-robust fugue subject, a descending woodwind line, turns into the movement’s opening gesture in m. 236.
This transformational process leads Beethoven out of the mysterious third movement into the blazing finale. Over the course of mm. 242-373, the trio theme gradually changes over a static background in which the piece’s four-note rhythmic kernel echoes in the timpani. Finally, a dominant chord emerges out of the mist, leading to the glorious C major, whose emergence over the horizon comes as a natural, organic outgrowth of the preceding material. Its unequivocally major opening, unlike that of the first and third movements, ends squarely on the tonic, and as if this, combined with the blaring trombones, piccolo, and contrabassoon weren’t enough to create a sense of unrestrained victory, Beethoven both incorporates transformed versions of the “fate” motive and revisits the C minor of the scherzo once again in order to recreate the journey from darkness to light in miniature, mirroring on a smaller scale his organic compositional process and at the same demonstrating the effectiveness of such an approach in taking the listener on a rich emotional journey.
