法國作曲家德布西(1862-1918) 被視為印象派音樂的開創者，也是二十世紀最偉大的作曲家之一。他的作品中不論在旋律、和聲、節奏、音色應用等皆有創新、突破的創作手法，且洋溢出獨特的美學理念。德布西因為作曲手法及風格的運用，突顯了他在音樂史上的定位，這些豐富的創新與美學理念中卻蘊含許多要素。 德布西作品中充分運用各種非傳統的音階、多變的節奏及將調性模糊化等手法，在他的作品中呈現出音樂中的朦朧感。也因為這種特色，往往有引人聯想的力量，對自然景物的描繪及抽象的聲音等。 筆者研究分析德布西的鋼琴作品。並藉由創作手法探討德布西的作曲風格、音型與調性、正確的音樂詮釋、速度的靈活性和彈性時間的使用、音量的詮釋、旋律和伴奏、音色的處理彈奏技巧、踏板的使用及演奏詮釋等為主題，得以更深一層瞭解德布西鋼琴作品的內涵。藉由這些探討，對德布西的鋼琴作品有整體性的認識，期待在鋼琴演奏上有可以有最直接的助益。

French composer Claude-Achille Debussy (1862-1918) is considered a pioneer in Impressionism music as well as one of the twentieth century’s greatest composers. Debussy's unique compositional technique is reflected in his innovation with regard to melodic, harmonic, rhythmic, and coloristic exploitation, as well as aesthetic approach. The uniqueness and significance of Debussy’s music contain many elements. Debussy’s works are filled with use of various non-traditional scales, rhythm changes and uncertain tonal centers. These are aspects of making his music unique and different from any other composers. His music is often associated with the description of the nature and abstract sounds. This paper seeks to examine and analyze the stylistic approaches of Debussy’s piano works. A general overview of Debussy’s piano music, compositional style and a historical background is discussed. The author summarizes Debussy’s aesthetic principles with regard to piano compositions. Detailed analyses of the musical interpretation, tempo flexibility, treatments of dynamic, use of pedals and performance practice are also discussed in depth. The author also discusses her findings concerning how such analyses might influence performance of Debussy’s piano music.
