Debussy and Ravel are often characterized as Impressionist composers within the classical music tradition. While neither composer explicitly identified with the Impressionist movement—often associated with visual arts—their music reflects similar aesthetic qualities, such as emphasis on atmosphere, color, and mood rather than traditional structure and form.
Debussy's music is known for its innovative use of harmony, orchestration, and texture, often evoking a sense of fluidity and ambiguity. Ravel, while also associated with Impressionism in some of his works, drew upon a broader range of influences, including neoclassicism, characterized by a return to older forms and styles.
In summary, while both are primarily known as Impressionist composers, Ravel's work also incorporates elements of neoclassicism.
