詞與曲之填作方式與詩作不同,作詩必須謹守平仄、對仗之觀念,而詞、曲則必須依其音律而作。故今日可以看見多種整理詞、曲體製、押韻、平仄之書,以作為後人填作詞、曲準則之詞譜與曲譜。然而曲之出現乃因詞變化而來,今日可見之詞譜與曲譜中,又有甚多「同名異調」之詞牌與曲牌。 今尋檢《御定曲譜》(簡稱《曲譜》)、《北詞廣正譜》、《九宮大成譜》等書,所錄〈天仙子〉之曲調,其體製稍有不同。今則根據《詞譜》與《曲譜》及其他曲譜所錄之〈天仙子〉資料為主,並以《花間集》、《全宋詞》、《全元散曲》中所載之同名詞曲,先考其調名緣由,再分別就其體製、句法、平仄、押韻及內容等五方面,對詞、曲中同名異調之詞牌,探析其同異之處,以期能對二者之特色及差異,有更進一步之認識。
The writing style in Tang Poems is different from in Song-Tsz or Yuan-Cyu. If you want writing Tang Poems, you must observe the concept of level-oblique and antithesis. While writing Song-Tsz or Yuan-Cyu, the rhythm of tone must be accorded. Nowadays, some books of Tsz Pu and Cyu Pu that arranged from Song-Tsz or Yuan-Cyu of which form, rhythm, and level-oblique. Those can be a criteria in writing Song-Tsz or Yuan- Cyu. Yuan-Cyu was changed from Tsz; nowadays, in some Tsz Pu and Cyu Pu which are in the same name but different tune of Tsz Pai and Cyu Pai. Searching for Yu Ding Cyu Pu named as Cyu Pu, Bei Tsz Guang Jeng Pu, Jiou Gung Da Cheng Pu and other books etc, the tune of ”Tian-Sian-Zih” was collected in some different form. To investigate the change of form from Song-Tsz to Yuan-Cyu, the author referred to Tsz Pu, Cyu Pu and other related books. In addition to investigate the original name of tone from Hua Jian Ji, Chiuan Song Tsz, Chiuan Yuan Shan Cyu, author based on five aspect, including form, sentence, level-oblique, rhyming, and content to research the same part or not about Tsz and Cyu that were in the same name but different tune. Author hopes this could be understood further in a distinguishing feature from Song-Tsz and Yuan-Cyu.
