通过对 20世纪 50年代以来在少数民族地区逐渐形成的三种新型的民歌演唱形式及其背景进行探讨, 可以认为这些新型的民歌演唱形式和背景, 首先会引起民歌本身形态上的微小变化, 继而引发原有音乐文化生态的改变, 进而更为加剧民歌形态上的变化。在这一过程中, 原有文化生态中人之心态的改变是最为关键的一环。 Through the discussion of three new forms of folk song singing and its background gradually formed in the ethnic minority areas from the 1950s onwards, it can be considered that these new forms of folk song singing and the background firstly lead to slight changes in the shape of the folk song itself, and then Triggering the original music and cultural changes in the environment, thereby further aggravating the morphological changes in folk songs. In this process, the change of mentality in the original cultural ecology is the most crucial part.
