Claude Debussy was a pioneering French composer whose innovative use of harmony, texture, and color helped define musical Impressionism. Breaking away from traditional structures, Debussy created evocative soundscapes that capture moods, nature, and subtle emotions. His works, including Clair de Lune, Prélude à l’après-midi d’un faune, and La Mer, revolutionized orchestral and piano music and remain staples in concert halls worldwide. Debussy’s legacy endures as a master of atmosphere and expressive nuance in classical music.
