Debussy, Claude

Achille-Claude Debussy (1862 – 1918) was a French composer. Along with Maurice Ravel he is considered the most prominent figure working within the style commonly referred to as Impressionist music, though he himself intensely disliked the term when applied to his compositions. Debussy was not only among the most important of all French composers but also a central figure in all European music at the turn of the twentieth century. His music virtually defines the transition from late-Romantic music to 20th century modernist music. In French literary circles, the style of this period was known as Symbolism, a movement that directly inspired Debussy both as a composer and as an active cultural participant.
