《古诗十九首》被刘勰称誉为“五言之冠冕”,除其“悲远之意”给人以深深的震撼之外,它独特的音乐般的节奏,也是其魅越千古的原因之一。从《古诗十九首》诗歌语言组织的重复与变化两方面进行分析,可以看出无论重复还是变化都必须源于诗歌的内在情感的表达意图,恰如其分的情感抒发,是其形成“怊怅之情”的原因所在。 “Nineteen Ancient Poems” was praised by Liu Xie as “the crown of five words”. Apart from its deep meaning of “sad meaning”, its unique music-like rhythm is also the reason of its more ancient charm one. From the analysis of the repetition and change of the language organization of the poems of the Nineteen Ancient Poems, we can see that both repetition and change must derive from the intent of the inner feelings of poetry and the expression of just the right emotion, which is the formation of “melancholy Love ”reason lies.
