The Huluhu (葫芦胡), a unique string instrument, is particularly significant among the Zhuang (壮族) and Buyi (布依族) ethnic groups of China. Known in the Zhuang language as “Ran Bup” (“Ran” for Huqin, a family of bowed string instruments, and “Bup” for gourd), the Huluhu is an essential instrument in the traditional music of these cultures. It is prominently featured in orchestral ensembles and is often used as an accompaniment in Zhuang and Buyi operas.
The Huluhu has its origins in an ancient instrument called the Xi Qin and shares a close historical connection with the Ma Gu Hu. It first appeared during the Qing Dynasty’s Qianlong era (1736–1795) and has been a part of Chinese musical culture for over two centuries. Initially, it was used in early forms of the Zhuang’s traditional “Bayin” (eight-tone) ensemble music and in Zhuang opera accompaniments.
The Huluhu resembles the Erhu in its construction but differs significantly in appearance. Its resonating body is shaped like a gourd, made from two natural gourd sections. The larger section is horizontally cut and covered with tung wood or bamboo, while the smaller section features a carved plum blossom petal-shaped sound hole. The neck of the Huluhu is made from wood or bamboo, often using red Tung wood or hardwood, and measures about 70 to 80 centimeters in length. The top of the neck is cylindrical and bends backward, supporting two tuning pegs made from boxwood or hardwood.
The Huluhu is played in a seated position, with its neck held upright and the gourd resting on the left leg. The left hand supports the neck and uses the fingers to press the strings, while the right hand holds a horsehair bow to play. The instrument is typically tuned in fifths, with a performing range spanning two octaves. The Huluhu is known for its solid sound and rich, deep timbre, making it suitable for both ensemble music and solo performances.
While both the Huluhu and Erhu are Chinese string instruments, they differ significantly in construction and sound. The Huluhu has a gourd-shaped resonating body, whereas the Erhu typically has a wooden soundbox covered with python skin. The Huluhu produces a rich, deep timbre, similar to the middle-range Banhu, while the Erhu is known for its more refined sound, often used in a wide range of Chinese musical styles.
Like many string instruments with a wooden body, the Huluhu requires careful maintenance due to its susceptibility to environmental conditions such as humidity. The wood needs to be protected from stress caused by varying humidity levels. It’s recommended to clean the rosin dust from the instrument with a soft cloth after use. High-quality Huluhus are polished with natural insect lacquer, a traditional Jiangnan technique, to enhance the wood’s smoothness and protect it. Proper care of the gourd skin is crucial, as frequent use maintains its elasticity, which is essential for the instrument’s sound quality. For storage, anti-moth measures and desiccants in humid areas are advised.
