Debussy shared with Schoenberg a petit bourgeois background. Born in 1862, the son of a shop keep er turned civil servant, he studied at the Paris Conservatory, where he struggled for several years to write a cantata sufficiently dull to win the sinecure of the academically oriented Prix de Rome. He finally succeeded with The Prodigal Son, in 1884.
In his spare time, Debussy sampled the wares of Paris’s avant-garde scenes, browsed in bookshops stocked with occult and Oriental lore, and, at the Bayreuth festivals of 1888 and 1889, fell under the spell of Parsifal. He attended Mallarmé’s elite Tuesday gatherings from around 1892 on, and also delved into more obscure regions—cultish Catholic societies such as the Kabbalistic Order of the Rose-Cross and the Order of the Rose-Cross of the Temple and Graal. Alas, it does not seem to be the case, despite claims put forward in the bestselling books Holy Blood, Holy Grail and The Da Vinci Code, that Debussy served as the thirty-third grand master of the Prieuré de Sion, which, according to a fabricated legend, guarded the secret of the Grail itself.
All this was standard-issue post-Wagnerian mumbo-jumbo. But Debussy’s honest quest for an unblemished, truthful musical language soon led him to other, distinctly un-Wagnerian sources. Just before his second trip to Bayreuth, in 1889, he attended the Paris Universal Exposition, which imported exotic sights and sounds from around the world, courtesy of a network of oppressive colonial regimes. It was here that Gauguin first became enamored of the tropical simplicity that eventually led him to take up residence in Tahiti. Debussy listened transfixed to the music of a Vietnamese theater troupe, with its effects of resonating gongs, and also to a Javanese gamelan ensemble, with its minimal scales of five notes, its delicate layering of timbres, its air of suspended animation. Gamelan music, Debussy wrote, “contained all gradations, even some that we no longer know how to name, so that tonic and dominant were nothing more than empty phantoms of use to clever little children.”
Debussy also immersed himself in painting and poetry, working out musical analogies for his sharpest aesthetic impressions. Although he was later labeled a musical “impressionist,” Renoir and Monet affected him little; he was influenced more by Anglo-American painters—by Turner’s way of suffusing a landscape with light, by Whistler’s way of subsuming a seascape into a single mood. He read the poetry of Paul Verlaine, whose Fêtes galantes he discovered on the shelves of his piano pupil and lover Marie-Blanche Vasnier. And Verlaine’s perfectly simple and elusive images—the color of moonlight, the music of rustling leaves and falling rain, the unreadable beauty of the sea, the motion of ancient dances, the souls of marionettes—fired Debussy’s musical imagination. To evoke the instrument of “Mandoline,” he wrote strumming chords in which fifths accumulate in dreaming towers. To capture the plain mystery of the line “singing branches,” he let common chords tumble over one another in defiance of textbook rules. In the midst of that kaleidoscopic rush of sounds, the whole-tone scale, one of Debussy’s trademark devices, made an early appearance. This, in turn, brought the young composer to the threshold of so-called atonality.
Musicians and listeners had long agreed that certain intervals, or pairs of notes, were “clear,” and that others were “unclear.” The quoted words can be found on a cuneiform tablet from the Sumerian city of Ur. The clearest intervals were the octave, the fifth, the fourth, and the major third, which form the lower end of the harmonic series (see, again, the opening measures of Thus Spake Zarathustra). By contrast, the tritone had for centuries been considered a disturbing entity. The whole-tone scale, which had begun showing up as an exotic effect in mid-nineteenth-century Russian and Central European music, consists of six equal steps in succession; if one goes upward starting from any C on a piano, it is three white keys followed by three black keys. The scale has the interesting property of being “clear” and “unclear” in equal measure. It abounds in bright major thirds, which can be obtained by moving two steps from any note. It also abounds in tritones (three steps). In visual terms, the scale generates a palette at once luminous and unreal, bright and hazy.
Debussy also made use of pentatonic scales, which he encountered many times at the Paris Exposition—those ancient, elementary five-note scales that crop up in folk traditions all over the world, from Africa to Indonesia. And he continued using diatonic (major-and minor-key) scales, though often in a spirit of nostalgia or satirical play.
The composer thought deeply about the physical facts underlying harmony. Hermann von Helmholtz, in his 1863 treatise, On the Sensations of Tone as a Physiological Basis for the Theory of Music, had explained the physics of the natural harmonic series and attempted to define human perceptions of consonance and dissonance in relation to it. As the waveforms of any two simultaneous tones intersect, they create “beats,” pulsations in the air. The interval of the octave causes a pleasant sensation, Helmholtz said, because the oscillations of the upper note align with those of the lower note in a perfect two-to-one ratio, meaning that no beats are felt. The perfect fifth, which has a three-to-two ratio, also sounds “clean” to the ear. Debussy may have known Helmholtz’s work; he certainly knew the eighteenth-century speculations of Rameau, who had linked standard harmony to the overtone series. Debussy loved to plant octaves and fifths in the bass and let a rainbow of narrower intervals shimmer in the upper air.
Debussy’s emblematic early work is Prelude to “The Afternoon of a Faun,” an orchestral narrative after a poem by Mallarmé, written and revised between 1892 and 1894. In the poem, a faun wonders how best to treasure the memory, or perhaps the dream, of two exquisite nymphs; he plays a song upon his flute, aware that music falls short of the viscerality of experience:
Long shall my discourse from the echoing shore
Depict those goddesses: by masquerades,
I’ll strip the veils that sanctify their shades.
The score begins by summoning the very music that the faun plays—a languid melody on the flute, descending a tritone and going back up. The harmony, likewise, swings across the tritone and comes to rest on a richly resonant B-flat dominant seventh, which, in classical harmony, would resolve to E-flat. Here the chord becomes a self-sufficient organism, symbolic of unbounded nature. Then the flute repeats its melody while a new texture forms around it. Debussy thus resists the Germanic urge to develop his thematic material: the melody remains static while the accompaniment evolves. Cloudy whole-tone sonorities mark the horizon of the faun’s vision, where shapes dissolve in mist.
All this suggestion eventually coalesces into a voluptuous, full-orchestral love song in D-flat major. The strings savor long, flowing unison lines, more akin to Indian ragas than to Wagner or Strauss. It is music of physical release, even of sexual orgasm, as Vaslav Nijinsky demonstrated in his undulating dance of the Faun at the Ballets Russes in 1912. “I hold the queen!” Mallarmé’s faun exults. Yet the tritone lingers in the bass, a mystery ungrasped.
With the opera Pelléas et Mélisande, sketched in the early 1890s and then extensively revised before its 1902 premiere, Debussy created a new kind of interior music drama, using Wagner as raw material. The text is by the Symbolist playwright Maurice Maeterlinck, and, as Strauss would do in Salome, Debussy set Maeterlinck’s play word for word, following its riddling prose wherever it took him. The love triangle of Pelléas, his half brother Golaud, and the inscrutable wandering princess Mélisande moves toward a grim climax, but most of the action takes place offstage; the score places the listener in a liquid medium into which individual psychologies have been submerged. Debussy’s established resources—whole-tone scales, antique modes, attenuated melodies that rise from wavering intervals—conjure an atmosphere of wandering, waiting, yearning, trembling.
Later come glimpses of a beautiful country on the other side. When Pelléas and Mélisande finally confess their love for each other—“I love you,” “I love you, too,” without accompaniment—the orchestra responds with a simple textbook progression moving from a tonic chord to its dominant seventh, except that
