Three bamboo tubes of different thickness are inserted into the bottom of the gourd. Each bamboo tube inserted into the gourd is inlaid with a copper or silver reed. The sound hole, called the main pipe, is flanked by attached pipes. There are only reeds on it, no sound hole (referring to the traditional cucurbit silk), and can only produce harmonics that resonate with the main pipe.
