Claude Debussy (1862-1918) was a French composer and pianist.
Debussy was an important figure in music history who broke away from the popular methods of musical composition in the 19th century. Debussy developed his own original concept of harmony and musical structure. According to Debussy, each piece of music was its own sound world and not something that should be bound by strict rules.
