What this dot point is asking
SEAB wants you to identify the main Chinese instruments by family and timbre, to describe the ensembles they play in (the Chinese orchestra and the silk-and-bamboo chamber group), and to recognise the pentatonic scales and heterophonic texture that give the music its character. The central insight is that Chinese ensemble music is often one shared melody, individually decorated, built on a five-note scale, a very different organising idea from Western harmony.
The answer
The main Chinese instruments
Learn these by their family and distinctive sound:
- Erhu: a two-string bowed fiddle (chordophone) with a singing, voice-like tone; the most recognisable Chinese melody instrument.
- Dizi: a transverse bamboo flute (aerophone) with a bright, slightly buzzing tone from a thin membrane.
- Pipa: a pear-shaped plucked lute (chordophone) played with the fingernails, capable of rapid, brilliant figures and tremolo.
- Guzheng: a long plucked zither (chordophone) with movable bridges, giving rippling glissandos.
- Yangqin: a hammered zither (chordophone) struck with two light beaters, bright and shimmering.
There are also Chinese percussion instruments (gongs, drums, cymbals) used in opera and festive music.
The Chinese orchestra
The modern Chinese orchestra is a large ensemble, organised loosely into bowed strings (erhu family), plucked strings (pipa, guzheng, yangqin), wind (dizi and the reedy suona and sheng) and percussion. It plays both traditional repertoire and newly composed works, sometimes adapting Western orchestral ideas.
The silk-and-bamboo ensemble
The silk-and-bamboo ensemble (sizhu) is a small chamber group named after its materials: silk for the strings and bamboo for the flutes. It plays refined, intricate music in an intimate setting, the players gently decorating a shared tune.
Pentatonic scales and heterophony
Two features define much of the sound:
- Pentatonic scale: a five-note scale (like the black keys of a piano), giving an open, gapped sound with no semitone clashes.
- Heterophony: several instruments play the same melody at once, but each decorates it in its own way, so the versions differ slightly and weave together, rather than forming chords (homophony) or independent tunes (polyphony).
Examples in context
Example 1. A famous erhu lament. A well-known traditional erhu piece spins a long, mournful, voice-like melody that exploits the instrument's expressive slides and dynamic shading. It shows why the erhu is treasured as the most singing of Chinese instruments and is a model for recognising its timbre.
Example 2. A silk-and-bamboo teahouse piece. Traditional sizhu music played in a teahouse setting weaves a shared pentatonic tune through erhu, dizi and plucked strings, each gently ornamenting the melody. It is an ideal example of heterophonic texture in an intimate Chinese chamber ensemble.
Try this
Q1. Name three Chinese instruments and the family each belongs to. [3 marks]
- Cue. Erhu (bowed string), dizi (wind or aerophone), pipa, guzheng or yangqin (plucked or struck strings), among valid choices.
Q2. Define a pentatonic scale and explain how it sounds. [2 marks]
- Cue. A pentatonic scale has five notes (like the black keys of a piano), giving an open, gapped sound with no semitone clashes.
Q3. Explain what heterophony is and how it differs from harmony. [2 marks]
- Cue. Heterophony is several instruments playing the same melody at once, each decorating it differently; it differs from harmony, where chords support a single melody.

Original5 marksIdentify each Chinese instrument from its description and state its family: (a) a two-string bowed fiddle with a singing, vocal tone; (b) a transverse bamboo flute with a buzzing membrane; (c) a pear-shaped plucked lute played with the fingernails; (d) a long plucked zither with movable bridges; (e) a hammered zither struck with two beaters.Show worked answer →
(a) The erhu, a bowed string (chordophone), with two strings and an expressive, voice-like tone.
(b) The dizi, a transverse bamboo flute (aerophone), whose buzzing comes from a thin membrane over an extra hole.
(c) The pipa, a pear-shaped plucked lute (chordophone), played with the fingernails for rapid, brilliant figures.
(d) The guzheng, a long plucked zither (chordophone) with movable bridges under each string.
(e) The yangqin, a hammered zither (chordophone) struck with two light beaters.
What markers reward: the correct instrument and family for each, using the timbral and playing clues given. The strongest answers note that the dizi's distinctive buzz comes from its membrane and that the erhu is famed for sounding like a human voice.
Original5 marksDescribe the texture and scale typical of much traditional Chinese ensemble music, explaining the terms heterophony and pentatonic, and name one Chinese ensemble type.Show worked answer →
Scale: much Chinese music uses a pentatonic scale, a five-note scale (for example the black-key pattern on a piano), which gives the music its characteristic open, gapped sound with no semitone clashes.
Texture: the texture is often heterophonic. This means several instruments play the same basic melody at the same time, but each decorates it in its own way, so the versions differ slightly and weave together rather than forming chords.
Ensemble: one example is the silk-and-bamboo ensemble (sizhu), a small chamber group of strings (silk) and flutes (bamboo); another is the modern large Chinese orchestra.
What markers reward: a correct definition of pentatonic (a five-note scale) and heterophony (one melody, simultaneously varied), and a named ensemble. Confusing heterophony with harmony, or with polyphony's independent tunes, loses marks.
