歌诗必类的观念与乐府的不合不类

The Concept of Ge Shi Bi Lei and the Inconformity between the Title and the Content of Yuefu Poems

同一歌题的古乐府与拟乐府的内容没有限定,歌题与内容不合不类是常见现象。学术界一般认为产生不合不类现象的原因是只限延用旧曲旋律,不限歌辞内容。然而乐府歌辞内容的不合不类在先秦雅乐中就已经存在,歌诗必类就是要求歌辞内容的相合相类,但实际上歌诗不类是常见现象。乐府能够接受不合不类就是因为先秦雅乐已经存在歌诗不类的普遍现象。

The Contents of the ancient Yuefu Poems and its imitation works with the same title are unrestricted.The inconformity between the title and content is a common phenomenon.The mainstream opinion of the academia is that this inconformity is due to the strict limitation of the use of previous rhythms and the contents of the poems are not restricted.However,this inconformity among Yuefu Poems has already existed in Pre-Qin Ya music.Ge Shi Bi Lei requires the conformity between the title and the content of the poems,however,the situation of inconformity is more often.The inconformity between the title and the content of Yuefu Poems is the continuation of the existence of the inconformity in Pre-Qin Ya music.
