宋詞研究學者提出許多詞律上的規定與特色，然而有關宋詞詞調之間的互動研究仍相當缺乏，因此本研究旨在探討北宋詞人姜夔的十七首自度曲當中語言形式的規定與音樂的關係。本篇研究包含語料庫與理論分析，其中語料庫分析針對結構、節奏與聲調歸納出姜夔十七首詞當中的傾向，並佐以數據分析。理論分析根據優選理論的框架說明姜夔作品中的語言形式如何選擇，並證實所有輸出值皆可用階級式制約來決定。本篇研究希望能解釋宋詞中語言與音樂的關係並為詞牌規定提出不同觀點。 / Researchers of Song verses have often proposed the rules to describe the poetic composition, but few have focused on the interactions between verse language and music. Therefore, the aim of the study attempts to explore how music and the linguistic requirements are related in Jiang Kuei’s seventeen verses. This research involves a corpus-based and a theoretical analyses. The corpus-based analysis focuses on structure, rhythm and tone to generalize the patterns of Jiang’s verses on a statistic basis. Under the framework of Optimality Theory, the theoretical analysis explains Jiang’s linguistic and musical arrangements in verses and confirms that the output forms are determined by a hierarchy of constraints. To conclude, this study sheds new light on the relationship between music and language and provides a fresh perspective on the Song verse formats.
