《乐府指迷》是南宋末季沈义父撰写的一本词学理论著作,其内容主要是针对雅词创作而言,其主旨是为雅词创作制作艺术规范。而何谓雅词,在沈义父看来则不仅是词的旨意之雅,还包括下字用语的文雅。在其理论来源方面,则主要来自于吴文英的梦窗词和周邦彦的清真词,两者之间又以清真词为主。 “Yuefu refers to fans” is a book written by Shen Yi-feng in the late Southern Song Dynasty. The content of this book is mainly for Ya-Ci creation, whose main purpose is to create artistic norms for Ya-Ci creation. And what is meant by elegant words, in the view of Shen Yi is not only the purpose of the word of elegance, but also includes the wording of the elegant words. In terms of its theoretical origin, it mainly comes from the Wu Meng-ying’s Dream Window words and Zhou Bangyan’s Halal words, and the two are mainly Halal words.
