德彪西以管弦乐、钢琴这两个领域的创作的巨大成就，开创了“印象主义音乐”的新型音乐风格。他常采用块状和弦及四、五度叠置和弦，建立在全音阶、东方五、六声音阶及教会调式音阶上的和声，和声的进行方式以平行进行为主。旋律是短小动机作主导。管弦乐配器注意突出管弦乐的特殊音区、色彩细腻的配器、“层层叠置”音响的技巧，以此追求独特迷人的音色及色彩效果。他的许多音乐作品，包括那些曾一度遭到攻击和诋毁的作品，都成为音乐史上的重要文献，为二十世纪现代音乐的发展奠 Debussy created a new musical style of “Impressionist Music” with great achievements in the orchestral and piano fields. He often uses chord chords and four- and five-degree superimposed chords to create harmony on diatonic, eastern fifth- and sixth-tonal scales and church-toned scales. Harmony takes place in parallel. Melody is short motivation to dominate. Orchestral device attention to highlight the orchestral special sound zone, delicate colors with the device, “stacked” sound technology, in pursuit of unique and attractive sound and color effects. Many of his musical compositions, including those once attacked and vilified, have become important documents in the history of music and laid the foundation for the development of modern music in the twentieth century
