Inside the hulusi hides a part few other instruments have: the drone pipes.

They have no finger holes and play no melody — each sounds one sustained tone, alongside the tune. And when the player does not want them, they can be plugged.

⚠️ The melody pipe sings; the drone pipes hum along — and the humming has an on-off switch. ⭐⭐ Rule ㉝: the drone pipes make harmony into a switchable part — an instrument that carries its own backup singers. Compare rule ⑧ (the sheng): the sheng's answer is "one reed for every note" — any note can be chorded; the hulusi's answer is "melody plus a fixed tone." Two Chinese answers to "how many notes can one instrument sound at once." And it carries a second name — "the instrument that can talk."

One gourd, three bamboo pipes

Three points:

1. The gourd is both chamber and resonator. The whole gourd stays intact — and every ethnic name writes it in (next section). 2. Three pipes, clear division. The longest, middle melody pipe has 7 holes (6 front, 1 back) and carries the tune; the two drone pipes "hold reeds but no finger holes" — their whole job is one sustained tone. 3. ⭐ One reed per pipe. Each pipe holds a tongue-shaped bronze reed inside the gourd — the same free-reed class as the sheng. But the hulusi's reed is made very thin with a tapering tip, so its "vibration is influenced by the air column, partaking of the soft-reed nature too" — scholars name this use of a bronze reed as a soft one, together with the sheng, one of "the rare exceptions in the world."

The drones: switchable harmony

⭐ The drone deserves careful reading:

• It sounds a tone that is simply there. No melody, no ornaments — a sustained tone. In the Ximeng Wa form, the two drones hold "a perfect fifth apart."
• It can be switched off. "When the sustained tone is not wanted or only one is wanted, the drones may be plugged" — the player decides on the spot whether there will be backup singers.
• ⭐ It is harmony's other answer. The sheng builds it into every reed; the hulusi builds it into a dedicated pipe — a solo instrument that carries its own background.
• ⭐ And structurally: because of the drones, the hulusi "sounds several notes at once" — precisely its biggest difference from the bawu (one pipe, one note at a time).

The name: five languages, one sum

The loveliest thing about the hulusi is inside its names — read them side by side:

⭐ No borrowing between them — yet every language performed the same sum: "a pipe word" + "gourd." Each people simply took two ready words in its own tongue. It says what they saw first: a gourd that happens to be a pipe. (Hence names-history item ⑬: one formula, independently true in each language.)

⚠️ And the Chinese name "hulusi" is young: in 1953, a Yunnan cultural team collecting songs in Dehong recorded it as "hulusi" for the first time — before that, it was only a crowd of local names.

Range

葫芦丝属气鸣乐器（自由簧 · 簧管耦合）。通行资料记其音域「常在 9 度以内，最多不超过 11 度」；傣族式主管记作「g~g1 一个八度」；改革后的多管形制可奏简易二声部并拓宽音域；实际音高随调（高 · 中 · 低音三种类型）而变。本图以约一个八度示意。记谱即实音。

⚠️ Honestly: the hulusi is traditionally a narrow-range instrument — about an octave. But it wrings that octave for everything: melody + drones + slides, taps, waves and circular breathing. Its ambition is not more notes; it is more flavour.

Where it comes from

⭐ And its family keeps a living ancestor: the hulusheng, still blown by the Hani, Lahu and Yi (the Lahu saying goes, "when the grain turns gold, the Lahu go wild" — out come the hulushengs and the dancing). The hulusi is this gourd line's "three-pipe" branch.

"The instrument that can talk"

In the Dai villages before 1949, a scene repeated nightly:

A young man walks from village to village with his hulusi, and plays it under the window, behind the house, of the girl he loves — the instrument speaking where words could not. Hence its name: "the instrument that can talk."

• ⭐ It echoes this site's elephant-foot drum — also called the "talking drum," with drummers said to converse in beats. On Yunnan's soil, "instruments that talk" keep appearing.
• ⭐ And its traditional repertoire is "one song per people": the Dai's *Mangshi Plain Mountain Song* · the Achang's *Love Song* · the De'ang's *Singing Tune* and *Bitter Tune* · the Wa's *Visiting Tune* — the titles themselves say who it belongs to.

Common misconceptions

• "The hulusi and bawu are the same instrument." Often paired, but one hard difference: the hulusi has several pipes and sounds several notes; the bawu has one pipe and sounds one. The hulusi's reed hides in the gourd; the bawu's reed is bare. (The bawu is the next entry.)
• "The drones are decoration or spares." ⚠️ They sound all the time as harmony — and they plug and unplug: whether the "backup singers" sing is part of playing.
• "Surely its range is more than an octave?" The sources: within a ninth, never past an eleventh; only reformed multi-pipe types widened it. It wins on flavour, not range.
• "It must be a Han instrument." ⚠️ It is kept by the Dai, Achang, De'ang, Wa and Bulang together — the Chinese name only dates from 1953.
• "It is a single-reed instrument." ⚠️ Some sources say "single reed," meaning one reed per pipe; by the reed-pipe three-way division (single / double / free), it stands with the sheng among the free reeds.

Timbre, and how to hear it

Three cues:

1. Hear the endlessness. Circular breathing keeps a phrase going for a long time — with the drones underneath, "the breath never stops" is its default state. 2. Hear the thickness. A reed sound wrapped in bamboo — one layer more "fuzzy-edged" than the dizi. 3. Hear the backup. Notice the line under the melody that never moves — that is a drone: that is its built-in band.

The family

⭐ Read the second column: the gourd family and the sheng family answer the same question — "how many notes at once, and how?" — the sheng line says "a reed for every note," the hulusi says "melody plus a drone line," and both grew from that same pre-Qin gourd.

Next

Its next stop is its single-pipe twin —

same reed, same land, same colour, but one pipe only: it can sing note by note, and cannot carry its own backup.

Next: the bawu — what remains when the gourd is taken away? :::
