This study serves as a comparison between the two works for flute, viola, and harp by Toru Takemitsu and Claude Debussy; influences of Debussy on Takemitsu and similarities between the two composers. It examines how cultural influences from both Japan and France affected each composer, and explores how other artists and composers impacted their writing. Particular focus will be put on Takemitsu's philosophical aesthetics, especially in his later years, and a comparative analysis between the two composers' trios, which include the harp. This study will present a comparative analysis of Takemitsu's trio, And then I knew 'twas Wind for Flute, Viola, and Harp, and Debussy's Sonata for Flute, Viola, and Harp, pointing out similarities and possible influences upon the composers, focusing on elements indicated in the score and writings by and about the composers.
