Achille-Claude Debussy (French: [aʃil klod dəbysi], 22 August 1862 – 25 March 1918), known since the 1890s as Claude-Achille Debussy or Claude Debussy, was a French composer. He and Maurice Ravel were the most prominent figures associated with Impressionist music, though Debussy disliked the term when applied to his compositions. He was made Chevalier of the Legion of Honour in 1903. He was among the most influential composers of the late 19th and early 20th centuries, and his use of non-traditional scales and chromaticism influenced many composers who followed.
Debussy's music is noted for its sensory content and frequent usage of nontraditional tonalities. The prominent French literary style of his period was known as Symbolism, and this movement directly inspired Debussy both as a composer and as an active cultural participant.

Debussy, the oldest of five children, was born Achille-Claude Debussy (he later reversed his forenames) on 22 August 1862 in Saint-Germain-en-Laye, France. His father, Manuel-Achille Debussy, owned a china shop there; his mother, Victorine Manoury Debussy, was a seamstress. The family moved to Paris in 1867, but in 1870 Debussy's pregnant mother fled with Claude to his paternal aunt's home in Cannes to escape the Franco-Prussian War. At the age of seven, he began piano lessons with an Italian violinist in his early 40s named Jean Cerutti, and his aunt paid for his lessons. In 1871 he drew the attention of Marie Mauté de Fleurville, who claimed to have been a pupil of Frédéric Chopin. Debussy always believed her, although there is no independent evidence to support her claim. His talents soon became evident, and in 1872, at age ten, Debussy entered the Paris Conservatoire, where he spent the next 11 years. During his time there he studied composition with Ernest Guiraud, music history/theory with Louis-Albert Bourgault-Ducoudray, harmony with Émile Durand, piano with Antoine François Marmontel, organ with César Franck, and solfège with Albert Lavignac, as well as other significant figures of the era. He also became a lifelong friend of fellow student and distinguished pianist Isidor Philipp. After Debussy's death, many pianists sought Philipp's advice on playing his works.
Debussy was experimental from the outset, favoring dissonances and intervals that were not taught at the Academy. Like Georges Bizet, he was a brilliant pianist and an outstanding sight reader, who could have had a professional career had he so wished. The pieces he played in public at this time included sonata movements by Beethoven, Schumann and Weber, and Chopin's Ballade No. 2, a movement from the Piano Concerto No. 1, and the Allegro de concert.
During the summers of 1880, 1881, and 1882, he accompanied Nadezhda von Meck, the wealthy patroness of Pyotr Ilyich Tchaikovsky, as she travelled with her family in Europe. The young composer's many musical activities during these vacations included playing four-hand pieces with von Meck at the piano, giving music lessons to her children, and performing in private concerts with some of her musician friends. Despite von Meck's closeness to Tchaikovsky, the Russian master appears[to whom?] to have had minimal effect on Debussy. In September 1880 she sent his Danse bohémienne for Tchaikovsky's perusal; a month later Tchaikovsky wrote back to her: "It is a very pretty piece, but it is much too short. Not a single idea is expressed fully, the form is terribly shriveled, and it lacks unity." Debussy did not publish the piece, and the manuscript remained in the von Meck family; it was eventually sold to B. Schott's Sohne in Mainz, and published by them in 1932.
A greater influence was Debussy's close friendship with Marie-Blanche Vasnier, a singer he met when he began working as an accompanist to earn some money, embarking on an eight-year affair together. She and her husband, Parisian civil servant Henri, gave Debussy emotional and professional support. Henri Vasnier introduced him to the writings of influential French writers of the time, which gave rise to his first songs, settings of poems by Paul Verlaine (the son-in-law of his former teacher Mme. Mauté de Fleurville).
As the winner of the 1884 Prix de Rome with his composition L'enfant prodigue, he received a scholarship to the Académie des Beaux-Arts, which included a four-year residence at the Villa Medici, the French Academy in Rome, to further his studies (1885–1887). According to letters to Marie-Blanche Vasnier, perhaps in part designed to gain her sympathy, he found the artistic atmosphere stifling, the company boorish, the food bad, and the monastic quarters "abominable". Neither did he delight in Italian opera, as he found the operas of Donizetti and Verdi not to his taste. Debussy was often depressed and unable to compose, but he was inspired by Franz Liszt, whose command of the keyboard he found admirable. In June 1885, he wrote of his desire to follow his own way, saying, "I am sure the Institute would not approve, for, naturally it regards the path which it ordains as the only right one. But there is no help for it! I am too enamoured of my freedom, too fond of my own ideas!"
Debussy finally composed four pieces that were sent to the Academy: the symphonic ode Zuleima (based on a text by Heinrich Heine); the orchestral piece Printemps; the cantata La damoiselle élue (1887–1888) (which was criticized by the Academy as "bizarre", although it was the first piece in which the stylistic features of his later style began to emerge); and the Fantaisie for piano and orchestra, which was heavily based on César Franck's music and therefore eventually withdrawn by Debussy. The Academy chided him for "courting the unusual" and hoped for something better from the gifted student. Although Debussy's works showed the influence of Jules Massenet, Massenet concluded, "He is an enigma."

During his visits to Bayreuth in 1888–9, Debussy was exposed to Wagnerian opera, which would have a lasting impact on his work. Like many young musicians of the time, he responded positively to Richard Wagner's sensuousness, mastery of form, and striking harmonies. Wagner's extroverted emotionalism was not to be Debussy's way, but the German composer's influence is evident in La damoiselle élue and the 1889 piece Cinq poèmes de Charles Baudelaire. Other songs of the period, notably the settings of Verlaine – Ariettes oubliées, Trois mélodies, and Fêtes galantes – are all in a more capricious style.
Around this time he met Erik Satie, who proved a kindred spirit in his experimental approach to composition and to naming his pieces. Both musicians were bohemians during this period, enjoying the same cafe society and struggling to stay afloat financially.
In 1889, at the Exposition Universelle in Paris, Debussy first heard Javanese gamelan music. He incorporated gamelan scales, melodies, rhythms, and ensemble textures into some of his compositions, most notably Pagodes from his piano collection Estampes.
Debussy's private life was often turbulent. At the age of 18 he began an eight-year affair with Marie-Blanche Vasnier, the wife of Parisian civil servant Henri Vasnier. The relationship eventually faltered following his winning of the Prix de Rome in 1884 and obligatory residence in Rome.
On his permanent return to Paris and his parents' home on the rue de Berlin (now rue de Liège) he began a tempestuous relationship with Gabrielle ('Gaby') Dupont, a tailor's daughter from Lisieux, soon cohabiting with her on the rue de Londres, and later the rue Gustave Doré. During this time he also had an affair with the singer Thérèse Roger, to whom he was briefly engaged. Such cavalier behaviour was widely condemned, and precipitated the end of his long friendship with Ernest Chausson.
He ultimately left Dupont for her friend Rosalie ('Lilly') Texier, a fashion model whom he married in 1899, after threatening suicide if she refused him. However, although Texier was affectionate, practical, straightforward, and well liked by Debussy's friends and associates, he became increasingly irritated by her intellectual limitations and lack of musical sensitivity. Moreover, her looks had prematurely aged, and she was unable to bear children.
In 1904 Debussy was introduced to Emma Bardac, wife of Parisian banker Sigismond Bardac, by her son Raoul, who was one of his students. In contrast to Texier, Bardac was a sophisticate, a brilliant conversationalist, and an accomplished singer. After dispatching Lilly to her father's home at Bichain in Villeneuve-la-Guyard on 15 July 1904, Debussy secretly took Bardac to Jersey for a holiday. On their return to France, he wrote to Texier on 11 August from Dieppe, informing her that their marriage was over, but still making no mention of Bardac. He briefly moved to an apartment at 10 avenue Alphand. On 14 October, five days before their fifth wedding anniversary, Texier attempted suicide, shooting herself in the chest with a revolver while standing in the Place de la Concorde; she survived, although the bullet remained lodged in her vertebrae for the rest of her life. The ensuing scandal was to alienate Debussy from many of his friends, whilst Bardac was disowned by her family.
In the spring of 1905, finding the hostility towards them intolerable, Debussy and Bardac (now pregnant) fled to England, via Jersey. Bardac's divorce was finalized in May. The couple settled at the Grand Hotel, Eastbourne, from 24 July to 30 August 1905, where Debussy corrected proofs to his symphonic suite La mer, celebrating his divorce from Texier on 2 August.
After a brief visit to London, the couple returned to Paris in September, buying a house in a courtyard development off the Avenue du Bois de Boulogne (now Avenue Foch) where Debussy resided for the rest of his life. Their daughter (the composer's only child) Claude-Emma was born there on 30 October. Her parents eventually married in 1908, their troubled union enduring until Debussy's death in 1918. Claude-Emma, more affectionately known as 'Chouchou', was a great musical inspiration to the composer (she was the dedicatee of his Children's Corner suite). Claude-Emma outlived her father by scarcely a year, succumbing to the diphtheria epidemic of 1919 after her doctor administered the wrong treatment.
Mary Garden, who played the part of Melisande in the original production of Pelléas et Mélisande in 1902, was to write of him: "I honestly don’t know if Debussy ever loved anybody really. He loved his music – and perhaps himself. I think he was wrapped up in his genius... He was a very, very strange man." 
Debussy died of rectal cancer at his Paris home on 25 March 1918, at the age of 55. He had been diagnosed with the cancer in 1909 after experiencing bleeding, and in December 1915 underwent one of the earliest colostomy operations ever performed. The operation achieved only a temporary respite, and occasioned him considerable frustration (he was to liken dressing in the morning to "all the labours of Hercules in one"). His death occurred in the midst of the aerial and artillery bombardment of Paris during the German Spring Offensive of World War I. The funeral procession made its way through deserted streets to Père Lachaise Cemetery as the German guns bombarded the city. The military situation in France was critical, and did not permit the honour of a public funeral with ceremonious graveside orations. His body was reinterred the following year in the small Passy Cemetery sequestered behind the Trocadéro, fulfilling his wish to rest 'among the trees and the birds'; his wife and daughter are buried with him.
Rudolph Reti points out the following features of Debussy's music, which "established a new concept of tonality in European music":
- Glittering passages and webs of figurations which distract from occasional absence of tonality;
- Frequent use of parallel chords which are "in essence not harmonies at all, but rather 'chordal melodies', enriched unisons", described by some writers as non-functional harmonies;
- Bitonality, or at least bitonal chords;
- Use of the whole-tone and pentatonic scale;
- Unprepared modulations, "without any harmonic bridge."
The application of the term "Impressionist" to Debussy and the music he influenced is a matter of intense debate within academic circles. One side argues that the term is a misnomer, an inappropriate label which the composer himself opposed. In a letter of 1908 he wrote: "I am trying to do 'something different' – an effect of reality... what the imbeciles call 'impressionism', a term which is as poorly used as possible, particularly by the critics, since they do not hesitate to apply it to [J.M.W.] Turner, the finest creator of mysterious effects in all the world of art."

From the 1890s Debussy began to develop his own musical language, which was largely independent of Wagner's style, coloured in part from the dreamy, sometimes morbid, romanticism of the Symbolist movement. He became a frequent participant at Stéphane Mallarmé's Symbolist gatherings, where Wagnerism dominated the discussion. However, in contrast to the enormous works of Wagner and other late romantic composers around this time, he chose to write in smaller, more accessible forms.
The Deux arabesques is an example of one of his earliest works, already developing his musical language. Suite bergamasque (1890) recalls rococo decorousness with a modern cynicism and puzzlement, and contains one of his most popular pieces, Clair de Lune. His String Quartet in G minor (1893) paved the way for his later more daring harmonic exploration, using the Phrygian mode as well as less standard scales such as the whole-tone, which creates a sense of floating, ethereal harmony. He was beginning to employ a single, continuous theme, breaking away from the traditional A–B–A form with its restatements and amplifications, which had been a mainstay of classical music since Haydn.
Debussy wrote one of his most famous works under the influence of Mallarmé, the revolutionary Prélude à l'après-midi d'un faune, which is truly original in form and execution. In contrast to the large orchestras so favoured by late romanticism, he wrote this piece for a smaller ensemble, emphasizing instrumental colour and timbre. Despite Mallarmé himself and colleague and friend Paul Dukas having been impressed by the piece, it was controversial at its premiere, but nevertheless established Debussy as one of the leading composers of the era.
The three Nocturnes (1899) include characteristic studies: in Nuages, using veiled harmony and texture; Fêtes, in exuberance; and Sirènes, using whole-tones. Debussy's only complete opera Pelléas et Mélisande premiered in 1902, after ten years of work, and contrasted sharply with Wagnerian opera. Based on the play by Maurice Maeterlinck, the opera proved to be an immediate success and immensely influential to younger French composers, including Maurice Ravel. These works brought a fluidity of rhythm and colour quite new to Western music.
La mer (1903–1905) essays a more symphonic form, with a finale that works themes from the first movement, although the middle movement, Jeux de vagues, proceeds much less directly and with more variety of colour. The reviews were once again sharply divided. Some critics thought the treatment to be less subtle and less mysterious than his previous works, and even a step backward, with Pierre Lalo complaining "I neither hear, nor see, nor feel the sea". Others extolled its "power and charm", its "extraordinary verve and brilliant fantasy", and its strong colors and definite lines.
He wrote much for the piano during this period. His first volume of Images pour piano (1904–1905) combines harmonic innovation with poetic suggestion: Reflets dans l'eau is a musical description of rippling water, while the second piece Hommage à Rameau is slow and yearningly nostalgic, taking a melody from Jean-Philippe Rameau's 1737 Castor et Pollux as its inspiration.
The evocative Estampes for piano (1903) give impressions of exotic locations. Debussy came into contact with Javanese gamelan music during the 1889 Paris Exposition Universelle. Pagodes is the directly inspired result, aiming for an evocation of the pentatonic structures employed by Javanese music.
He wrote his famous Children's Corner Suite (1908) for his beloved daughter, Claude-Emma, whom he nicknamed Chouchou. The suite recalls classicism – the opening piece Doctor Gradus ad Parnassum refers to Muzio Clementi's collection of instructional piano compositions Gradus ad Parnassum – as well as a new wave of American ragtime music. In the popular final piece of the suite, Golliwogg's Cakewalk, Debussy also pokes fun at Richard Wagner by mimicking the opening bars of Wagner's prelude to Tristan und Isolde.

The first book of Préludes (1910), twelve in total, proved to be his most successful work for piano. The Preludes are frequently compared to those of Chopin.[clarification needed Which set?] Debussy's preludes are replete with rich, unusual and daring harmonies. They include the popular La fille aux cheveux de lin (The Girl with the Flaxen Hair) and La Cathédrale Engloutie (The Engulfed Cathedral), although since he wanted people to respond intuitively to these pieces, their titles were placed at the end of each one in the hope that listeners would not make stereotype images as they listened.
Larger scale works included his orchestral piece Iberia (1907), a triptych medley of Spanish allusions and fleeting impressions which was begun as a work for two pianos, and also the music for Gabriele D'Annunzio's mystery play Le martyre de Saint Sébastien (1911). A lush and dramatic work, written in only two months, it is remarkable in sustaining a late antique modal atmosphere that was otherwise touched only in relatively short piano pieces.
As Debussy's popularity increased, he was often engaged as a conductor throughout Europe during this period, most often performing Pelléas, La Mer, and Prélude à l'après-midi d'un faune. He was also an occasional music critic, to supplement his conducting fees and piano lessons, writing under the pseudonym "Monsieur Croche". He avoided analytical dissection and attempts to force images from music, saying "Let us at all costs preserve this magic peculiar to music, since of all the arts it is most susceptible to magic." He could be caustic and witty, sometimes sloppy and ill-informed. He was for the most part enthusiastic about Richard Strauss and Stravinsky, and worshipful of Chopin and Bach, the latter being acknowledged as "the one great master." His relationship to Beethoven was a complex one; he was said to refer to him as "le vieux sourd" (the old deaf one) and adjured one young pupil never to play Beethoven's music for "it is like somebody dancing on my grave." It was said that "Debussy liked Mozart, and he believed that Beethoven had terrifically profound things to say, but that he did not know how to say them, because he was imprisoned in a web of incessant restatement and of German aggressiveness." He also admired the works of Charles-Valentin Alkan. Schubert and Mendelssohn fared much worse, the latter being described as a "facile and elegant notary".

Debussy's harmonies and chord progressions frequently exploit dissonances without any formal resolution. Unlike in his earlier work, he no longer hides discords in lush harmonies, and the forms are far more irregular and fragmented. These chords that seemingly had no resolution were described by Debussy himself as "floating chords", and were used to set tone and mood in many of his works. The whole tone scale dominates much of his late music.
His two final volumes of works for the piano, the Études (1915), interpret similar varieties of style and texture purely as pianistic exercises, and include pieces that develop irregular form to an extreme, as well as others influenced by the young Igor Stravinsky (a presence too in the suite En blanc et noir for two pianos, 1915). The rarefaction of these works is a feature of the last set of songs, the Trois poèmes de Mallarmé (1913), and of the Sonata for flute, viola and harp (1915), though the sonata and its companions also recapture the inquisitive Verlainian classicism.
With the sonatas of 1915–1917 there is a sudden shift in the style. These works recall Debussy's earlier music in part, but also look forward, with leaner, simpler structures. Despite the thinner textures of the Violin Sonata (1917), there remains an undeniable richness in the chords themselves. This shift parallels the movement commonly known as neo-classicism, which became popular after his death in 1918. He planned a set of six sonatas, but had only completed three (cello, flute-viola-harp, and violin) before he died.
The final orchestral work by Debussy, the ballet Jeux (1912) written for Sergei Diaghilev's Ballets Russes, contains some of his strangest harmonies and textures in a form that moves freely over its own field of motivic connection. At first, Jeux was overshadowed by Igor Stravinsky's The Rite of Spring, which was composed in the same year as Jeux, and was premiered only two weeks later by the same ballet company. Decades later, composers such as Pierre Boulez and Jean Barraqué pointed out parallels to Anton Webern's serialism in this work.
Other late stage works, including the ballets Khamma (1912) and La boîte à joujoux (1913), were left with the orchestration incomplete, and were later completed by Charles Koechlin and André Caplet, who also helped him with the orchestration of Gigues (from Images pour orchestre) and Le martyre de St. Sébastien.
The second set of Préludes for piano (1913) features Debussy at his most avant-garde, where he uses dissonant harmonies to evoke specific moods and images. He consciously gives titles to each prelude which amplify the preludes' tonal ambiguity and dissonance. He uses scales such as the whole tone scale, musical modes, and the octatonic scale in his preludes which exaggerate this tonal ambiguity, making the key of each prelude almost indistinguishable at times. The second book of Preludes for piano represents his strong interest in the indefinite and esoteric.

Although Pelléas was Debussy's only completed opera, he began several opera projects which remained unfinished, perhaps due to his fading concentration, increasing procrastination, and failing health. He had finished some partial musical sketches and some unpublished libretti for operas based on Poe's The Devil in the Belfry (Le diable dans le beffroi, 1902–?1912) and The Fall of the House of Usher (La chute de la maison Usher, 1908–1917) as well as considering projects for operas based on Shakespeare's As You Like It and Joseph Bedier's La Legende de Tristan.
Further plans, such as an American tour, more ballet scores, and revisions of Chopin and Bach works for re-publication, were all cut short by poor health and the outbreak of World War I.
Some people have claimed that Debussy structured parts of his music mathematically. Roy Howat, for instance, has published a book contending that Debussy's works are structured around mathematical models even while using an apparent classical structure such as sonata form. Howat suggests that some of Debussy's pieces can be divided into sections that reflect the golden ratio, frequently by using the numbers of the standard Fibonacci sequence.
Debussy's influences were wide-ranging. He acquired a taste for parallel motion in fifths, fourths and octaves from medieval music, and an appreciation for figuration and arabesque from the Baroque masters. He especially had a great love for the French clavier composers Couperin[clarification needed François Couperin?] and Rameau, as well as J. S. Bach. Chopin and Liszt were also powerful influences, not only in terms of pianistic layout and harmonic ingenuity, but also because of their willingness to create new forms to accommodate their material.
Among the Russian composers of his time, the most prominent influences were Tchaikovsky[clarification needed This seems to contradict what it says in the 'Early Life' section], Balakirev, Rimsky-Korsakov, Borodin and Mussorgsky. It can be inferred that from the Russians "Debussy acquired his taste for ancient and oriental modes and for vivid colorations, and a certain disdain for academic rules".[attribution needed] Mussorgsky's opera Boris Godunov directly influenced one of Debussy's most famous works, Pelléas et Mélisande. In addition to the Russian composers, one of Debussy's biggest influences was Richard Wagner. According to Pierre Louys, Debussy "did not see 'what anyone can do beyond Tristan.'"
After Debussy's Wagner phase, he started to become immensely interested in non-Western music and its unorthodox approaches to composition. Specifically, he was drawn to the Javanese Gamelan: a musical ensemble from the island of Java that played an array of unique instrumentation, including gongs and metallophones. He first heard the gamelan at the 1889 Paris Exposition. He was not interested in directly quoting his non-Western influences, but instead allowed this non-Western aesthetic to generally influence his own musical work, for example, by frequently using quiet, unresolved dissonances, coupled with the damper pedal, to emulate the "shimmering" effect created by a gamelan ensemble.
Debussy was just as influenced by other art forms as he was by music, if not more so. He took a strong interest in literature and visual art, and used these mediums to help shape his unique musical style. He was heavily influenced by the French symbolist movement of the 1880s, which encompassed poetry, visual art, and theatre. He shared the movement's interest in the esoteric and indefinite and their rejection of naturalism and realism. Specifically, "the development of free verse in poetry and the disappearance of the subject or model in painting influenced him to think about issues of musical form." He became personally acquainted with writers and painters of the movement, and based some of his own works on those of the symbolists. The poet Stéphane Mallarmé was a major influence, who in talking of "a 'musicalization' of poetry" laid claim to a strong connection between music and his own poetry. His Prélude à l'après-midi d'un faune was directly influenced by Mallarmé's poem "Afternoon of a Faun". Like the symbolists in respect to their own art forms, Debussy aimed to reject common techniques and approaches to composition and attempted to evoke more of a sensorial experience for the listener with his works. Since his time at the Paris Conservatoire, he believed he had much more to learn from artists than from musicians, who were primarily interested in their musical careers.
Above all, Debussy was inspired by nature and the impression it made on the mind, making a pantheistic profession of faith when he called "mysterious Nature" his religion. 'I do not practice religion in accordance with the sacred rites. I have made mysterious Nature my religion. I do not believe that a man is any nearer to God for being clad in priestly garments, nor that one place in a town is better adapted to meditation than another. When I gaze at a sunset sky and spend hours contemplating its marvellous ever-changing beauty, an extraordinary emotion overwhelms me. Nature in all its vastness is truthfully reflected in my sincere though feeble soul. Around me are the trees stretching up their branches to the skies, the perfumed flowers gladdening the meadow, the gentle grass-carpeted earth, ... and my hands unconsciously assume an attitude of adoration. ... To feel the supreme and moving beauty of the spectacle to which Nature invites her ephemeral guests! ... that is what I call prayer.'
Contemporary painter James Abbott McNeill Whistler (who lived in France between 1855 and 1859) had a profound influence on the composer. In 1894, Debussy wrote to violinist Eugène Ysaÿe describing his Nocturnes as "an experiment in the different combinations that can be obtained from one color – what a study in grey would be in painting."
Influence on later composers
Debussy is widely regarded as one of the most influential composers of the 20th century. His innovative harmonies were influential to almost every major composer of the 20th century, particularly Maurice Ravel, Igor Stravinsky, Olivier Messiaen, Béla Bartók, Pierre Boulez, Heitor Villa-Lobos, Henri Dutilleux, Ned Rorem, George Gershwin, and the minimalist music of Steve Reich and Philip Glass as well as the influential Japanese composer Toru Takemitsu. He also influenced many jazz musicians, including Duke Ellington, Bix Beiderbecke, Branford Marsalis, and Steve Kuhn. He also had a profound impact on contemporary soundtrack composers such as John Williams, because Debussy's colourful and evocative style translated easily into an emotional language for use in motion picture scores.
