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 non-traditional 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 Among his most famous works are his Clair de Lune, his Three Nocturnes and his orchestral piece La Mer.

Joseph Maurice Ravel was a French composer who is often associated with impressionism along with his elder contemporary Claude Debussy, although both composers rejected the term. In the 1920s and 1930s Ravel was internationally regarded as France's greatest living composer.
Born to a music-loving family, Ravel attended France's premier music college, the Paris Conservatoire; he was not well regarded by its conservative establishment, whose biased treatment of him caused a scandal. After leaving the Conservatoire Ravel found his own way as a composer, developing a style of great clarity, incorporating elements of baroque, neoclassicism and, in his later works, jazz. He liked to experiment with musical form, as in his best-known work, Boléro (1928), in which repetition takes the place of development. He made some orchestral arrangements of other composers' music, of which his 1922 version of Mussorgsky's Pictures at an Exhibition is the best known.
As a slow and painstaking worker, Ravel composed fewer pieces than many of his contemporaries. Among his works to enter the repertoire are pieces for piano, chamber music, two piano concertos, ballet music, two operas, and eight song cycles; he wrote no symphonies and only one religious work. Many of his works exist in two versions: a first, piano score and a later orchestration. Some of his piano music, such as Gaspard de la nuit (1908), is exceptionally difficult to play, and his complex orchestral works such as Daphnis et Chloé (1912) require skilful balance in performance.

Carl Nielsen was a Danish musician, conductor and violinist, widely recognized as his country's most prominent composer.
Brought up by poor but musically talented parents on the island of Funen, he demonstrated his musical abilities at an early age. He initially played in a military band before attending the Royal Danish Academy of Music in Copenhagen from 1884 until December 1886. He premiered his Op. 1, Suite for Strings, in 1888, at the age of 23. The following year, Nielsen began a 16-year stint as a second violinist in the prestigious Royal Danish Orchestra under the conductor Johan Svendsen. In 1916, he took a post teaching at the Royal Academy and continued to work there until his death.
Although his symphonies, concertos and choral music are now internationally acclaimed, Nielsen's career and personal life were marked by many difficulties, often reflected in his music. The works he composed between 1897 and 1904 are sometimes ascribed to his "psychological" period, resulting mainly from a turbulent marriage with the sculptor Anne Marie Brodersen. Nielsen is especially noted for his six symphonies, his Wind Quintet and his concertos for violin, flute and clarinet. In Denmark, his opera Maskarade and many of his songs have become an integral part of the national heritage. His early music was inspired by composers such as Brahms and Grieg, but he soon developed his own style, first experimenting with progressive tonality and later diverging even more radically from the standards of composition still common at the time. Nielsen's sixth and final symphony, Sinfonia semplice, was written in 1924–25. He died from a heart attack six years later, and is buried in Vestre Cemetery, Copenhagen.

Camille Saint-Saëns was a French composer, conductor, pianist and organist. He was a musical prodigy, writing his first pieces of music at the age of four and making his concert debut at the age of ten. During this concert he astonished the audience by playing one of the 32 piano sonatas of Beethoven at its request. After his studying at the Conservatory of Paris he followed a career as a church organist at Saint-Merri and later La Madeleine in Paris. He was also a successful freelance composer and pianist in France and abroad.
Saint-Saëns initially helped to introduce German composers such as Robert Schumann and Richard Wagner in France. However, from 1870 onwards anti-German sentiments began to arise in France as a result of the Franco-Prussian War, which enhanced support for the idea of a pro-French musical society. In 1871 Saint-Saëns consequently founded the Société Nationale de Musique together with Romain Bussine, that was devoted to the promotion of French music and organised concerts on which young composers could perform their works.
Saint-Saëns was a keen traveler, and made 179 trips to 27 different countries during his life. He favoured Algeria and Egypt, were he gained inspiration for compositions such as the Suite Algérienne and the Fifth Piano Concerto, also known as The Egyptian.
Saint-Saëns' best-known works include the First Cello Concerto, Third Symphony, the opera Samson et Dalila, Danse Macabre and Le carnaval des animaux, a humorous suite in which various animals are musically portrayed. However, he never wanted the last work to be performed, since it was contrary to his image as a serious composer.

Gabriel Fauré was a French Romantic composer, organist, pianist and teacher. He was one of the foremost French composers of his generation, and his musical style influenced many 20th-century composers. Among his best-known works are his Pavane, Requiem, Nocturnes for piano and the songs Après un rêve and Clair de lune. Although his best-known and most accessible compositions are generally his earlier ones, Fauré composed many of his most highly regarded works in his later years, in a more harmonically and melodically complex style.
Fauré's music has been described as linking the end of Romanticism with the modernism of the second quarter of the 20th century. When he was born, Chopin was still composing, and by the time of Fauré's death, jazz and the atonal music of the Second Viennese School were being heard. During the last twenty years of his life, he suffered from increasing deafness. In contrast with the charm of his earlier music, his works from this period are sometimes elusive and withdrawn in character, and at other times turbulent and impassioned.
