广西壮族自治区隆林各族自治县的扁牙一带,散居着一部分苗族同胞,在那里盛传一种苗语叫“长积”[j(?)ngji)的民间乐器。苗语的“长”乃对乐器之统称,“积”表示“两个”,故汉译为“双管”。双管属气鸣竹质簧管型乐器。双管由大小、长短一样的两支吹管左右并排捆绑在一起而成。这两支吹管的结合,民间呼之为“公”、“母”,各由管身、芯子、哨子和一个共同的挡嘴片组成(见图1)。 Some of the Miao compatriots live in the vicinity of the flat teeth of the various ethnic autonomous counties in Longlin Prefecture of Guangxi Zhuang Autonomous Region, where they spread a folk musical instrument called “Longji” [j (?) Ngji). Miao language “long” is the general term for the instrument, “plot” that “two”, so the Chinese translated as “double tube.” Shuangming is a gas spring bamboo tube type instrument. Double pipe by the size of the same length of the two blowing pipe side by side tied together. The combination of these two blowpipe, folk called “male”, “female”, each by the tube, core, whistle and a common block mouth piece (see Figure 1).
