The sheng's harmony and free reed
Sounding on both blow and draw — the only Chinese wind that plays harmony, and the ancestor of the harmonica and accordion

Fourteen aerophones are done in this section, and every one of them plays one note at a time.
Only this one does not.
「笙……也是中国传统吹管乐器中唯一能演奏和声的乐器。」
⭐⭐ This page is the harmony overview for Sheng — three main lines: sounding on blow and draw, the three intervals of traditional harmony, and the free reed's journey west.
| Class | Assignment |
|---|---|
| HS class | Aerophone · free-reed · with definite pitch |
| Scope | ⭐⭐ the technique and acoustics overview for Sheng — no new instrument, only the technical threads from that entry gathered into three main lines: ① sounding on blow and draw ② the three intervals of traditional harmony ③ the free reed's journey west — ancestor of the harmonica and accordion |
| In short | ⭐⭐ blow and draw both sound（breathing does not stop the sound）｜⭐⭐ traditional harmony = fifth above + octave above + fourth below（all three come from the harmonic series itself） |
| Bayin | gourd（⭐ a record of origin — early sheng used a gourd wind-chest; today's is bronze） |
⭐⭐ Line 1: it sounds on blow and draw — breathing does not stop the music
Ordinary winds push air one way. The sheng does not:
「有别于一般吹管乐器，笙吹、吸皆可发音，故有不少特殊的演奏技巧。」
⭐⭐ Two consequences, both large:
① Breathing does not stop the sound. It sounds while you inhale — a phrase can run forever. Other winds must break to breathe; the sheng does not.
② Every reed sounds in both directions. 「簧片可独立振动而不受管体约束」— and that physical fact is exactly what later let the sheng "become" the harmonica and the accordion (see line 3).
⭐⭐ Blow-and-draw also built a whole family of techniques: four kinds of air vibrato （tongue, belly, throat, chest-belly）; one mouth technique 「呼舌」is unique to the sheng; and flower-tongue comes in three grades（细 · 粗 · 爆）.
⭐⭐ Line 2: the three intervals of traditional harmony — all from the harmonic series
The sheng plays harmony, but it does not stack just any interval:
「笙在传统乐曲的演奏常会叠加上五度、上八度或下四度和声，称之为传统和声。」
⭐⭐ None of the three is arbitrary — each comes from the harmonic series itself:
| Interval | Where it sits in the series |
|---|---|
| ⭐ fifth above | the first new pitch above the second partial (the most natural consonance) |
| ⭐ octave above | the second partial again (the cleanest doubling) |
| ⭐ fourth below | the inversion of that fifth (the same fifth, an octave down) |
⭐⭐ The sheng's harmony grew out of one tube's natural overtones, not out of European harmony theory.
⭐⭐ And the physics holds it up: 「笙的独特之处在于其『一簧一音』的发声原理与自由簧结构，使其能同时演奏多个音符，具备和声与复调表现力」— ⭐ each tube has its own reed, so several tubes sound together (compare the dizi: one tube, six holes, one pitch at a time).
⭐⭐ On the modern sheng this reaches its limit: 「演奏者可通过气息控制与指法配合， 同时呈现旋律、和声与低音伴奏，使笙的表现力堪比西洋乐器中的管风琴」.
⭐⭐ Line 3: the free reed travels west — ancestor of the harmonica and accordion
The whole timeline, without a gap:
| Year | Event |
|---|---|
| antiquity | the sheng reaches Persia by the Silk Road |
| ⭐ 1740 | the missionary Johann Wilde brings a sheng to Europe |
| ⭐ 1777 | the French sinologist Amiot carries one from Beijing to Paris and explains its structure in《论中国音乐》 |
| ⭐ 1780 | the Danish scientist Kratzenstein rebuilds the organ reed on the sheng's principle |
| ⭐ 1810 | the French maker Grenié builds the orgue expressif |
| ⭐ after | 「口琴、手风琴、簧管风琴相继问世」 |
⭐⭐ And the musicologist Curt Sachs gives the sheng the very first sentence of his History of Instruments:
「风琴和簧管风琴的自由簧并非欧洲的发明。它来自中国这个自由簧的伟大故乡，至少两千年前，它就以口弦乐器'笙'的形式存在了……」
⭐⭐ In one line: 「这些乐器均借鉴了笙的自由簧技术，簧片可独立振动而不受管体约束，从而实现了键盘化与便携化，有力推动了19 世纪浪漫主义音乐的普及与发展」— ⭐⭐ the organ's walk out of the church and into the pocket began with the sheng.
⭐⭐ A counter-intuitive detail: the hole chooses a reed, it does not change pitch
This one splits the sheng from the whole flute family:
「每根笙管下端近斗处都有一个指孔。吹奏时，根据取音需要，按住这根管下端的指孔，并通过吹嘴吹气或吸气来策动簧片与笙管内空气柱产生耦合振动而发音。」
⭐⭐ The hole selects which tube sounds; it does not alter the pitch. Flutes: one tube, six holes, the fingers change the pitch. Sheng: a dozen tubes, each with its own reed — ⭐⭐ the stopped tube is silent, the open tube sounds.
⭐⭐ And that is exactly why it can play harmony: stop several tubes at once (or leave them open), and several reeds speak together.
⭐⭐ The tuning tool is a drop of wax
A small detail, and a moving one:
「簧片的音高依据簧舌尖上点粘蜡珠的大小来调节。」
⭐⭐ A bigger wax bead → heavier tongue → lower pitch; smaller → lighter → higher. ⭐ A sheng maker's entire intonation lives on a thread of wax.
⭐ And there was「银字制笙」— the《新唐书》records「银字制笙，以银作字，饰其音节」: ⭐ silver inlay on the tubes to mark the pitches.
⭐⭐ Sheng and yu: the big one lost to the small one
Two instruments of the same family, opposite fates:
「从战国到汉代的文献中，共同记载着笙和竽两种同类乐器」；⭐⭐ 「竽，笙之大者」 — 「笙体小、簧少；竽体大、簧多」。The《说文解字》gives the yu 36 reeds.
⭐⭐ But by the Song：「竽则销声匿迹，在教坊十三部中，只有笙色而无竽色。」
⭐ Why: the yu 「只用于雅乐，逐渐失去在历史上的重要作用」— an instrument tied to one repertoire retires with it. The sheng survived because it accompanied everything.
⭐⭐ The yu of "滥竽充数" really is gone.
⭐⭐ The Zeng Houyi sheng: the earliest specimens, and an even-numbered surprise
「1978 年，湖北随县曾侯乙墓出土了 6 支战国初期的古匏笙……这是我国发现的最早的笙。」
⭐⭐ Their reed counts are 14, 16 and 18 — even numbers — 「与古籍中所载的笙的簧数（多为 13、17、19 等奇数）不同，为研究笙的发展提供了新的资料」.
⭐⭐ And: 「簧片为竹制，其形状、制作和调音方法，与铜簧片完全一样」— ⭐ those bamboo reeds from 2,400 years ago were tuned the way bronze reeds are tuned today.
⭐⭐ Four registers, plus a job no other wind has
「笙的音色明亮甜美，高音清脆透明，中音柔和丰满，低音浑厚低沉，音量较大。」
⭐⭐ And one role nothing else has: 「在和其他乐器合奏的时候，能起到调和乐队音色、丰富乐队音响的作用」→ ⭐⭐ a large Chinese orchestra fields high, middle and low sheng — ⭐ a harmony instrument naturally splits into voices.
Recap: three sentences on the sheng
| Q | A |
|---|---|
| ⭐ The key point | ⭐⭐ it sounds on blow and draw — breathing never stops the line; ⭐⭐ each reed sounds both ways（the physical precondition for the harmonica） |
| ⭐⭐ Where the harmony comes from | ⭐⭐ traditional harmony = fifth above + octave above + fourth below — ⭐⭐ all three come from the harmonic series itself, grown out of one tube's overtones, not learned from European theory |
| ⭐⭐ One reed per note | ⭐⭐ each tube has its own reed（compare the dizi's six holes on one tube）→ several tubes sound together → polyphony to rival the organ |
| ⭐⭐ What the hole means | ⭐⭐ the hole chooses a reed, it does not change pitch — the stopped tube is silent, the open one sounds（the flute family is exactly the opposite） |
| ⭐ Tuning | ⭐⭐ 「簧片的音高依据簧舌尖上点粘蜡珠的大小来调节」 — big bead low, small bead high; ⭐ the tool is a drop of wax |
| ⭐⭐ The westward line | Persia → ⭐1740 Wilde → ⭐1777 Amiot《论中国音乐》→ ⭐1780 Kratzenstein → ⭐1810 Grenié → harmonica, accordion and reed organ follow |
| ⭐⭐ Sachs' verdict | the opening of the History: 「风琴和簧管风琴的自由簧并非欧洲的发明。它来自中国这个自由簧的伟大故乡」 |
| ⭐⭐ Sheng and yu | ⭐⭐ 「竽，笙之大者」（sheng small and few-reeded / yu large and many-reeded, 36 reeds in the Han record）→ Song: 「只有笙色而无竽色」→ ⭐ the yu, tied to ritual music, retired; the sheng, accompanying everything, survived |
| ⭐ Earliest finds | ⭐⭐ the Zeng Houyi sheng（c. 433 BC, six specimens, 2,400+ years old）: 14/16/18 reeds — even（the texts record odd numbers）; bamboo reeds tuned exactly like bronze ones |
| ⭐ Asian family | Tang-era arrival in Japan（the Shōsōin keeps Tang 17-tube sheng and yu）→ the Japanese shō sounds 11-note chords · Korean saenghwang · Lao-Thai khaen · Indonesian genggong |
| ⭐ Tone | 「高音清脆透明 · 中音柔和丰满 · 低音浑厚低沉」+ ⭐⭐ it colours and binds the orchestra（high / middle / low sheng in the big ensemble） |
| Bayin | gourd（⭐ a record of origin: early chest was a gourd; wood after the Tang; bronze finally replaced wood） |
「我有嘉宾，鼓瑟吹笙」— the sheng's name has travelled three thousand years inside the Book of Songs.
⭐⭐ Its ancient character 「龢」is the character for "harmony" — this instrument was built for "together" from its name onward.
笙属气鸣乐器（自由簧驱动，簧管耦合）。传统笙十三至十七簧；现代改良至二十一至三十六簧。现代民族管弦乐队设高音笙（G3–F♯6）、中音笙（C3–B5）、次中音笙（G2–F♯5）、低音笙（C2–G4）四种。笙吹吸皆鸣，同一簧片两个方向都能发声；传统和声叠上五度、上八度或下四度，三个音程全部来自泛音列本身。记谱即实音。

- ⭐⭐ 本页是笙的技法与声学专题，不引入新乐器，只把散在该条里的技术线索收拢成三条主线：① 吹吸皆鸣 ② 传统和声的三个音程 ③ 簧片原理西传 —— 口琴与手风琴的祖先
- ⭐⭐ 主线一 · 吹吸皆鸣（本批最该记住的一条） —— 「有别于一般吹管乐器，笙吹、吸皆可发音，故有不少特殊的演奏技巧」；⭐⭐ 这意味着两件事：① 换气不等于停（吸气时也在出声，乐句可以不断）· ② 每根簧片两个方向都能响 → ⭐⭐ 「簧片可独立振动而不受管体约束」—— 这正是它后来能"变成"口琴与手风琴的物理前提
- ⭐⭐ 笙是世界上最早使用自由簧的乐器：「笙是世界上最早使用自由簧的乐器，也是世界上现存大多数簧片乐器的鼻祖」；⭐⭐ 音乐学家库尔特·萨克斯《乐器史》开篇：「风琴和簧管风琴的自由簧并非欧洲的发明。它来自中国这个自由簧的伟大故乡，至少两千年前，它就以口弦乐器'笙'的形式存在了……」—— ⭐ 这是乐器学奠基人把整本书的第一句话让给了笙
- ⭐⭐ 主线二 · 传统和声的三个音程（本页最实用的一段） —— 「笙在传统乐曲的演奏常会叠加上五度、上八度或下四度和声，称之为传统和声」；⭐⭐ 这三个音程不是随便选的：上五度 = 泛音列第二分音之上的第一个新音（最自然的协和）· 上八度 = 同音的重复（最干净）· 下四度 = 上五度的转位（低八度里的那个五度）→ ⭐⭐ 三个音程全部来自泛音列本身 —— 笙的"和"是从一根管的自然泛音里长出来的，不是从欧洲和声学里学来的
- ⭐⭐ "一簧一音"与复调能力：「笙的独特之处在于其『一簧一音』的发声原理与自由簧结构，使其能同时演奏多个音符，具备和声与复调表现力，这在中国民族乐器中独树一帜」；⭐⭐ 在现代笙上：「演奏者可通过气息控制与指法配合，同时呈现旋律、和声与低音伴奏，使笙的表现力堪比西洋乐器中的管风琴」依专题类资料
- ⭐⭐ "唯一能奏和声"这句话有多重：「也是中国传统吹管乐器中唯一能演奏和声的乐器」—— ⭐⭐ 这一族里没有第二件：笛子·箫·唢呐·管子·埙全部单声；⭐ 笙能奏和声的物理原因就是"每根管独立一根簧"（对照竹笛：一根管上开六个孔，一次只能一个音）
- ⭐⭐ 主线三 · 簧片原理西传的时间线（口琴与手风琴的祖先）：「笙最早通过『丝绸之路』传到波斯」→ ⭐ 1740 年「传教士约翰·怀尔德将笙带至欧洲」→ ⭐ 1777 年「法国汉学家阿米奥自北京携笙返回巴黎，并在《论中国音乐》中详细阐释其结构，由此激发欧洲乐器制造的革新浪潮」→ ⭐ 1780 年「丹麦科学家克拉岑斯坦依据笙的簧片原理改进风琴簧片」→ ⭐ 1810 年「法国音乐家格雷尼埃发明簧片风琴」→ ⭐「此后数十年间，口琴、手风琴、簧管风琴相继问世」依百科与专题类资料
- ⭐⭐ 西传的总结句（本页最响的一句）：「这些乐器均借鉴了笙的自由簧技术，簧片可独立振动而不受管体约束，从而实现了键盘化与便携化，有力推动了 19 世纪浪漫主义音乐的普及与发展」→ ⭐⭐ 管风琴从教堂里走出来变成口袋里的口琴，第一步是从笙开始的
- ⭐ 笙的构造（三部分）：「主要由笙簧、笙苗（即笙体上的许多长短不一的竹管）和笙斗（即连接吹口的笙底座）三部分构成」；⭐ 「每根笙管下端近斗处都有一个指孔。吹奏时，根据取音需要，按住这根管下端的指孔，并通过吹嘴吹气或吸气来策动簧片与笙管内空气柱产生耦合振动而发音」 → ⭐⭐ 发声的关键是"按住"：不按的管不响 —— 按孔是"选哪根管响"，不是"改变音高"（这是它与笛族的根本区别：笛族按孔改音高，笙按孔选簧片）
- ⭐⭐ 八音归属是"匏"（葫芦）的由来：「笙为匏类乐器」——「早期的笙，用葫芦作笙斗」；「后来吹奏者觉得笙斗体大、质脆，吹奏费气，于唐代以后改为木制，经过世代的流传，最后铜斗又取代了木斗」→ ⭐⭐ 八音里的"匏"记的是它的出身，不是它的现状（今天的笙斗早已是铜的，但分类沿用古称）
- ⭐ 簧片的调音法（很具体）：「簧片的音高依据簧舌尖上点粘蜡珠的大小来调节」—— ⭐⭐ 蜡珠大 → 簧舌重 → 音低；蜡珠小 → 簧舌轻 → 音高。⭐ 调音的工具是一滴蜡

- ⭐⭐ 音色的四个区（本段少见地分了四档）：「笙的音色明亮甜美，高音清脆透明，中音柔和丰满，低音浑厚低沉，音量较大」；⭐⭐ 而且它还有一层"调和"功能：「在和其他乐器合奏的时候，能起到调和乐队音色、丰富乐队音响的作用」→ ⭐⭐ 大型的民族管弦乐队里，笙有时要用到高音、中音和低音三种笙 —— 和声乐器天生就分声部
- ⭐ 现代形制与音域：「经改良后簧数扩展至二十一至三十六簧」；现代国乐团多用三十六簧笙取代传统笙，并设高音笙（G3–F♯6）·中音笙（C3–B5）·次中音笙（G2–F♯5）·低音笙（C2–G4）依百科类资料
- ⭐⭐ 技法清单（吹吸带来的特殊技巧）：笙的演奏技巧「约可分为气息类颤音（舌颤音 · 腹颤音 · 喉颤音 · 胸腹式气颤音，以末者最常用）、口内技术（吐音 · 花舌 · 呼舌 · 舌阻音 · 顿气 · 剁气）、手指技术（指颤音 · 点顿音 · 刮奏 · 捂音）」；⭐⭐ 其中「呼舌」为笙独有技巧；⭐⭐ 「花舌又分细花舌、粗花舌、爆花舌等种类」；⭐ "最明显的比如葫芦丝、巴乌、竹笛等管乐，都用笙的技巧——双吐、三吐等" → ⭐⭐ 笙的技巧传遍了整个吹管家族依百科类资料
- ⭐⭐ "和"的文化线（收口用）：「笙跨越三千年的生命轨迹，生动诠释了『和』这一核心精神的永恒魅力。它是礼乐文明中『音声相和』的技艺载体，是『与人和』『与天和』的文化象征」；⭐ 《诗经·小雅·鹿鸣》：「我有嘉宾，鼓瑟吹笙。吹笙鼓簧，承筐是将」依专题类资料
