在先秦两汉“天人”思想影响下，雅乐与俗乐的审美目的、审美功能和审美特征“近而不同”。从分化过 程来看，雅乐“天人之和”与俗乐“天人之乐”的审美追求有别，审美主体对“神性”“人性”的选择随之不同，并在 “庙堂”“民间”的差异化场景中完成“分乐而序”。从合流成因来看，雅俗之乐以天人之情的同一性为基础，借助审美共通性推动天人之教，实现天人之美的价值统一。分化源于对“神”的崇拜，合流则见证“人”的崛起。

Under the influence of the idea of "heaven and man" in the pre-Qin and Han Dynasties, the aesthetic purpose, function and characteristics of refined music and popular music were "close but different". From the perspective of the differentiation process, the aesthetic pursuit of the "harmony of heaven and man" of refined music was different from that of the "happiness of heaven and man" of popular music, and the aesthetic subjects' choices of "divinity" or "humanity" were different, so the "orders of differing music" were completed in the differentiated scenes of "temples" and "the folks". From the perspective of confluence causes, refined and popular music were based on the identity of the feelings of heaven and man, and promoted the teaching of heaven and man with the help of aesthetic commonality, so as to realize the value unity of the beauty of heaven and man. Differentiation originated from the worship of "gods", while confluence witnessed the rise of "man".
