唐后乐府诗的界定与分类

由于历史、文化、审美等多方面的原因，宋、辽、金、元、明、清六朝的“唐后乐府诗”，与传统的“汉唐乐府诗”相比，具有明显的质的变化与不同。从立题名篇的角度来看，唐后乐府诗可分为旧题乐府与新题乐府两大类，新题乐府系由即事类乐府、歌行类乐府、竹枝类乐府等所构成，应对各自的界定与类别特点进行甄别与考察。研究唐后乐府诗，不能以研究汉唐乐府诗的眼光进行审视。日本学人松浦久友提出的“非乐府歌行”说，与唐后乐府诗的实况严重不符，不能用以界定唐后的“乐府歌行”。

Definition and Classification of Post Tang Yuefu Poems

Caused by history, culture, aesthetic standards, etc. post Tang Yuefu poems of the 6 dy- nasties of Song, Liao, Jin, Yuan, Ming and Qing are qualitatively changed and apparently different from those of the 2 dynasties of Han and Tang, Viewing it from the perspective of famous Yuefu pieces, post Tang Yuefu poems fall into 2 categories of old and new themes. Neco theme Yuefu consists of extempore, Gexing and Zhuzhi Yuefu. In the study of Post Tang Yuefu poems,it won＇t do to scrutinize the works in the same light as with Han and Tang Yuefu poems. The thesis of ＂non Yuefu Gexing＂ by Matsuura Misasuke,a Japanese scholar,is utterly inconsistent with the reality of post Tang Yuefu poems and cannot be used to define post Tang Yuefu Gexing.
