Who is considered a key composer of the impressionist movement?

Claude Debussy is widely recognized as a key composer of the impressionist movement in music. His work is characterized by its focus on atmosphere, color, and texture rather than traditional melody and harmony, which aligns with the principles of impressionism in art. Debussy's compositions often evoke natural scenes and emotions through innovative use of harmony, scales, and orchestration. Notable pieces, such as "Clair de Lune" and "Prélude à l'après-midi d'un faune," exemplify these qualities, showcasing his ability to convey mood and imagery, much like the impressionist painters of his time.

In contrast, other composers like Ravel, while often associated with impressionism, implemented different techniques and had a more structured compositional style. Stravinsky and Schoenberg are linked with different musical movements—Stravinsky with neoclassicism and avant-garde techniques, and Schoenberg with expressionism and the development of atonality. Therefore, Debussy's distinctive use of musical language solidifies his position as a cornerstone of the impressionist movement.
