唐近體詩興盛原因爲何？諸多「中國文學史」均有云及。唯其中有一重要內在因素被忽略，即「初唐定型之近體詩格律簡易可行」。余考唐人詩學理論，復印證彼時詩歌作品，明白可知初唐宮廷詩人熱衷「近體詩」聲律病犯之討論，逮元兢《詩髓腦》提出「調聲三術」理論，而「近體詩」之積極聲律因此定型。尤重要者，因此種五言詩格律簡易可行，故能自宮廷而民間，復藉科舉造勢，遂風行天下，成為促進唐詩興盛之有利因素之一。雖謂唐五律聲律從齊梁調演變，其間亦有無數詩人參與研發，但研發成功，且使唐五律正式脫離齊梁調者，應推首功于元兢。在中國文學史上，「調聲三術」關係唐詩興盛之內在因素，至深且大，不可不知。

Why "latest poetry" was so booming in Tang Dynasty? This subject was covered by many books on Chinese Literature History. But one of the important internal factors was neglected. That is, the simplicity and feasibility of "latest poetry" form finalized in the beginning of Tang Dynasty. I've gone through the poetic theories and verified once again with those poetic works. It is obvious that the poets in Tang Palace loved to discuss the sound principles for "latest poetry". Until Yuan Chin proposed the theory of "Three Magic's of Sound Adjustment" in his book named "The spine and brain of poetry", the positive sound principles for "latest poetry" are finalized. Specially important was that the form for "Five Words Poetry" is simple and feasible. From Palace to general public, along with the advocacy of civil service examination, the popularity finally came. It is therefore one of the factors benefiting the booming of Tang Poetry. Even though the Five Sounds of Tang Poetry had evolved from Chi & Liang Sound; and, many poets involved in the R & D, the most contributing person should be Yuan Chin who helped Five words poetry sever from Chi & Liang Sound. In Chinese Literature history, the theory of "Three Magic's of Sound Adjustment" casts a deep and great influence on poetry booming in Tang Dynasty. Therefore, we could not ignore this internal factor.
