The kobyz (qobyz / kobyz / кыл қобыз) is an instrument made of horsehair: the strings are horsehair, the bow is horsehair, and the pegbox is often carved as a horse head.

And the thing it does most often is learn to sound like hooves.

⭐⭐ The main line: two horses

⭐⭐ Horsehair is at once its string, its bow, and the thing it imitates.

The most concentrated case on the site of one material running through an entire instrument: the harp needs two (wood and strings), the violin three (wood, bow hair, strings), ⭐⭐ the kobyz needs one — horsehair, from the strings to the bow to the horse it learns to call like.

⭐⭐ And that material is its own name: the Kyrgyz call it kyl kyyak (кыл кыяк), and kyl means horsehair. ⭐⭐ Against the site's other mismatched names — the dutar says two and can carry fourteen strings, the santur says a hundred strings and has seventy-two — the kobyz's name names its material from the start, and it has never changed its mind.

⭐⭐ An instrument made of horsehair, carved with a horse head, used to imitate the sound of hooves: ⭐⭐ the horsehair, the horse head and the hooves are all one and the same horse.

⭐⭐ A handle running through the body

⭐ Carved in one piece of wood — apricot in the Kyrgyz version; ⭐ usually sixty to seventy centimetres long.

⭐ The sound chamber is covered with goatskin — ⭐ in some versions the back is skinned as well.

⭐⭐ A handle runs through the body and ends in a spike — ⭐⭐ and the instrument is held upright between the knees, like a cello. ⭐⭐ That one rod is the whole manual for its posture: not at the shoulder, not under the chin, but standing between the legs, with the bow passing outside the string.

⭐⭐ A rule worth carrying away: an instrument's posture is not a matter of taste, it is the direct consequence of how the thing is held. — ⭐⭐ A rod running through the body means the instrument can only be clamped upright, only sit close to the floor, only have a player behind it. (Against the rebab: also a spike fiddle, also held upright on a spike; ⭐⭐ but the rebab's body is skinned while the kobyz's is carved out of solid wood — one speaks through skin, the other through a wooden cavity.)

⭐⭐ The string is not stopped on a board, it is squeezed against the handle

⭐⭐ This is an instrument with no fingerboard. ⭐⭐ The string is not stopped on a board; it is squeezed against the handle with the fingernail — ⭐⭐ so the pitch is continuous and sliding.

⭐⭐ This is the fourth form of the site's master line 「intonation is a position, not a scale」: the violin's position sits in the frets of a board · the erhu's in the positions of a fingerboard · the oud's in the contact point between finger and string on a fretless board · ⭐⭐ the kobyz's in the pressure between a fingernail and the handle — with no frets there are no countable steps, only one unbroken line.

⭐ Bow: ⭐⭐ short, strung with horsehair.

⭐⭐ The two strings' division of labour: one for the melody, one for resonance and drone. ⭐⭐ In a jyrau's accompaniment that second string is the one that repeats a single note to hold the voice up.

⭐⭐ From a shaman's sacred instrument to an orchestra's roster

⭐⭐ Traditionally the kobyz was a sacred instrument held by shamans and folk healers (baksı / bahsı) — ⭐⭐ legend gave it the power to drive out evil, to heal, and even to drive away death. ⭐⭐ An instrument whose efficacy is written into legend: among the closest things on the site to a relic.

⭐⭐ In 2025 Uzbekistan inscribed the kobyz on UNESCO's Representative List of the Intangible Cultural Heritage of Humanity (number 02329). ⭐⭐ The same object, a sacred object on one side and a UNESCO entry on the other — that timeline is the clearest case on the site of an instrument's identity being changed twice.

⭐⭐ And the change in between was the most thorough of the three: ⭐⭐ in the Soviet period, in the 1930s, national orchestras were being built, and the kobyz was reworked into a four-string metal-stringed version that came close to a violin — ⭐⭐ able to play the hardest pieces in the violin literature.

⭐⭐ This is the site's standard specimen of an instrument rebuilt in order to enter the concert hall: ⭐⭐ the auto-tune, whose algorithm preceded its effect · the santur, constrained by its modes · the cimbalom, given pedals and full chromaticism · the kobyz, given a fourth string and metal strings — ⭐⭐ four instruments, four ways of being taken over by a system, by an algorithm, by a modal system, by machinery and by a roster respectively.

⭐⭐ And yet the old two-stringed form is still treasured in the villages and among the people. ⭐⭐ A rule worth carrying away: once an instrument has been reworked, the reworked version and the original can live at the same time — the reworked one goes into the concert hall, the original stays in the village; ⭐⭐ and the original does not disappear because the reworked one is more 「advanced」; it holds a post the reworked one cannot take.

⭐ The Tatar branch: it flourished before the fall of the Kazan Khanate in 1552, and was still preserved among dervishes at the end of the 18th century. ⭐⭐ A bowed string handed down in a dervish order — against the rebab's survival in the Mevlevi lodge: ⭐⭐ two marginalised bowed instruments both found a setting where they did not have to become violins.

⭐⭐ küi: the short instrumental that imitates birds and hooves

⭐⭐ The Kazakh küi — a short, titled instrumental (instrumental narration): ⭐⭐ it deliberately imitates bird calls and horse hooves — 「purposeful imitation of sounds such as bird calls or horse hooves」.

⭐⭐ That is the second layer of the horse: the kobyz does not merely use horsehair, it also learns to reproduce the sound of hooves. ⭐⭐ An instrument made of horsehair, carved with a horse head, learning to sound like hooves — ⭐⭐ three kinds of horse folded into one object.

⭐⭐ And this is not an improvisational flourish but a genre with a name: ⭐⭐ a küi is a short titled instrumental, and the title is often a bird, an animal or a stretch of landscape. ⭐⭐ 「Imitating hooves」 is not an extra trick of this instrument but the basic requirement of the genre it belongs to.

⭐⭐ jyrau: when the human voice starts imitating the fiddle

⭐⭐ The Karakalpak jyrau (narrator-singer) accompanies epic and dastan with it, in three ways: ⭐⭐ sounding in unison with the vocal line during sung passages · ⭐⭐ repeating a single note as a drone that holds the voice up · ⭐⭐ taking over the melody when the speaker falls silent.

⭐⭐ The third is the one that shows the craft: in the gap where the man stops speaking, the instrument takes up the melody — ⭐⭐ one instrument covers the pause of the voice, so that there is no seam between man and fiddle.

⭐⭐ And then comes the most beautiful case on the site of an instrument shaping the human voice in return: ⭐⭐ the hoarse voice of the jyrau is now explained as 「imitating the kobyz's own sound」 (historically it was associated with shamanic practices) — ⭐⭐ the human throat imitating the fiddle, whose sound in turn is horsehair rubbing inside a wooden cavity. ⭐⭐ The most concentrated chain on the site of material → instrument → person: horsehair becomes a string, the string wears itself hoarse, and the performer then wears his own throat down to that hoarseness.

⭐⭐ A rule worth carrying away: instruments are not only played by people, they are also imitated by them. —— Usually it is the person who reshapes the instrument to suit themselves; ⭐⭐ here it is the other way round: the instrument's roughness became the standard for the voice, and the artist tuned his own throat to an instrument.

⭐⭐ Against the rebab and the Chinese spike fiddles

⭐⭐ Two things come out of this table: first, ⭐⭐ among the fretless instruments the kobyz is the most extreme of all — it does not even stop the string on the string, but between a fingernail and the handle; second, ⭐⭐ the fates of the kobyz and the rebab make a pair: ⭐⭐ one was pushed out of the door by the violin (the market), the other had its genes rewritten by the violin (the state) — ⭐⭐ 「disappearing」 and 「being transformed」 are two different things, and after the transformation the original is still in the village.

⭐⭐ Lineage and destinations

The kobyz is a bowed chordophone (chordophone · bowed · spike fiddle). Form: carved in one piece of wood (apricot in the Kyrgyz version), usually sixty to seventy centimetres long; the sound chamber is covered with goatskin, and in some versions the back is skinned as well; a handle runs through the body and ends in a spike, and the instrument is held upright between the knees like a cello; two strings, one for the melody and one for resonance and drone, both made of horsehair, as is the bow, which is short; many pegboxes are carved as horse heads. ⚠️ No published measurement of its compass was found, so the figure takes about two octaves, the usual span of a two-stringed fretless instrument, as a schematic and not as a measured value; the middle is taken as the usual working register. ⭐⭐ The reason for this compass is unlike that of any other bowed string: ⭐⭐ it has no fingerboard, and the string is not stopped on a board but squeezed against the handle with the fingernail — so the pitch is continuous and sliding, and the positions available are not a ladder of steps but one unbroken line. ⭐⭐ For comparison, the Chinese erhu has a fingerboard and its pitches fall on frets and positions; and the kobyz's other identity — ⭐⭐ the four-string metal version made for the Soviet national orchestras in the 1930s, which came close to a violin and could play the hardest pieces in the violin literature — ⭐⭐ under one name, the narrowness of two strings and the breadth of four are two entirely different ways of living. Written equals sounding.
