Claude-Achille Debussy(August 22, 1862 – March 25, 1918) was a French composer. His music is noted for its sensory component and how it is not often formed around one key or pitch. Often Debussy's work reflected the activities or turbulence in his own life. 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.
