* Impressionism: Debussy was a leading exponent of Impressionism, a late 19th-century art movement that sought to capture the fleeting impressions of the moment. In music, Impressionism is characterized by its use of shimmering, evocative harmonies, delicate orchestration, and a focus on creating atmosphere.

* Symbolism: Debussy was also influenced by Symbolism, a literary and artistic movement that sought to express ideas through the use of symbols and metaphors. In music, Symbolism is often characterized by its use of ambiguous and suggestive melodies, harmonies, and textures.

* Orientalism: Debussy was fascinated by the music of the East, and he incorporated elements of Japanese, Chinese, and Indian music into his own compositions. This is most evident in his use of pentatonic scales, exotic percussion instruments, and colourful orchestration.

* Medievalism: Debussy also looked back to the music of the Middle Ages for inspiration. He was particularly drawn to the plainchant melodies and modes of medieval music, which he used in his own compositions to create a sense of timelessness and mystery.
