克勞德．阿希爾．德布西（Claude Achille Debussy, 1862-1918）的二十四首鋼琴前奏曲是其創作中的經典作品，以創新的語法與精湛的演奏技巧，巧妙地融入優美的意境、美學中，是充分發揮鋼琴特色的精鍊作品。其中許多題材取自自然萬物。本文以其中兩首描繪「風」的前奏曲，進行系統性的技法、美學、演奏技巧及詮釋探討，並比較兩首作品創作手法之異同。由此兩首作品來探討德布西對於「風」的各種想像、音型、和聲、節奏、力度、術語、主題、曲式、彈奏技巧等設計，以了解作曲者如何將自然界的抽象印象與意念，轉為嚴謹的音樂創作，再呈現出如繪畫般的音樂，並完成具說服力的演奏詮釋。

The twenty-four piano preludes can be considered as one of the most excellent pieces made by Claude Achille Debussy. The new composing languages and virtuoso piano techniques have skillfully and eloquently become one with nature and beauty, which fully brought out the melody of a piano. Many of Debussy’s pieces are made by the inspiration of nature. This research will mainly analyze two of his preludes on “Wind” systematically in composing techniques, aesthetic point of view, performance practice, and interpretation. Thorough an analysis of Debussy’s two “Wind” pieces, one can see that to Debussy, “Wind” consists of figuration, harmony, rhythm, dynamic, terms, form, style, and piano techniques. In turn, one is then able to understand how a composer utilize some unsubstantial thing such as nature and turn them into music pieces that depict nature in a powerful and persuasive piano presentation.
