所谓整体化功能可从两个层面体现出来。首先,在这些山村社区的民歌文化系统内部,不仅音乐、乐人、乐境等子系统之间关系相互缠结,难以区分,而且在每一子系统内部各要素之间也存在同样情况。其次,再从民歌文化系统的外部功能来看,民歌文化与其他文化系统的关系也存在相互缠结,彼此难分的情况。本文以布朗族民歌为例,对民歌整体化功能模式进行描述。 The so-called overall function can be reflected from two levels. First of all, not only are the relationships among the subsystems of music, musicians and music in these mountain village communities tangled and separated from each other, but the same is true of the various elements within each subsystem. Second, from the perspective of the external function of the folk song culture system, the relationship between the folk song culture and other cultural systems is also tangled and difficult to distinguish from each other. This article takes the Brang folk songs as an example to describe the integrated function mode of folk songs.
