Mouth organ of the Dai, Achang, Wa, and other minority cultures in southern Yunnan province, China. Hulusi is a Han Chinese name; local names include bilangdao (Dai), huluxiao (Achang), and baihongliao (Wa). The instrument has a bamboo melody pipe and one or two bamboo drone pipes inserted into the bottom (flower) end of a small bottleneck gourd windchest. Traditionally the pipes are secured with hardened beeswax though nowadays usually with a stronger adhesive. A thin blowpipe is similarly mounted in the neck end of the gourd. The melody pipe (c25 cm or longer) has six or more fingerholes and (attached near its closed end within the gourd) a thin, triangular free reed of bamboo, bronze, or silver in a rectangular frame, similar to the reed assembly of the bawu. On some instruments, one short drone pipe, with the same kind of reed, runs parallel to the melody pipe; more commonly nowadays, a second drone is attached to the opposite side of the melody pipe, either with its reed tuned to a different pitch, or without a reed for symmetrical appearance....
