THREE-BODY TECHNOLOGY World in Gourd is a virtual instrument that realistically emulates the sounds and articulation of a Chinese Hulusi, a clarinet-like wind instrument. The Hulusi features a bamboo wind tube, a gourd resonance chamber, and two auxiliary wind tubes, which allow for two fixed notes to be played in harmony. This traditional Chinese instrument produces a lovely, mellifluous sound used to express romantic relationships, or to accompany lyrical dances.

World in Gourd is compatible with Mac and Windows. It runs as standalone software or operates in AU, VST2, and AAX formats.
