How the hulusi makes its sound
In the Hornbostel–Sachs system, which classifies instruments by how they produce sound, the hulusi belongs to the free reeds and interruptive aerophones: air is periodically interrupted by a vibrating reed or blade – the accordion, harmonica, sheng and bullroarer.
More broadly it is one of the aerophones (wind instruments), where sound comes from vibrating air.
Press play above and watch the spectrum: the evenly spaced peaks are harmonics, and their relative strength is what gives the instrument its character.
From Wikipedia
The hulusi (simplified Chinese: 葫芦丝; traditional Chinese: 葫蘆絲; pinyin: húlúsī), also known as the cucurbit flute and the gourd flute, is a free reed wind instrument from China, Vietnam, and the Shan State, played also by the indigenous people of Assam. It is held vertically and has three bamboo pipes that pass through a Calabash gourd wind chest; the center pipe has finger holes and the outer two are typically drone pipes. It is not uncommon for a hulusi to have only one drone pipe while the second outer pipe is merely ornamental. The drone pipe has a finger hole which allows it to be stopped. Advanced configurations have keyed finger holes similar to a clarinet or oboe, which can greatly extend the range of the hulusi to several octaves.
