Claude-Achille Debussy (French: [klod aʃil dəbysi]; 22 August 1862 – 25 March 1918) 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 his native France in 1903. Debussy 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.
