The racket is the crumhorn's bass brother: the same double reed, conical bore and wind cap, the same covered, undynamic character — but it solves one additional problem that is purely about space.
⚠️ Physical size and register ought to be locked together How low a wind instrument sounds depends on how long its air column is. Low notes need a long bore; and a player's arms are only so long. So bass wind instruments have always wrestled with one question: where does the tube go? - The bassoon's answer: fold it once, into a U. - The contrabassoon's: fold it several times. - The racket's answer: fold it to the limit — back and forth inside a column barely 25 cm tall. Hence "column bassoon"; German is more vivid still — Wurstfagott, literally a "sausage bassoon".
Its reason to exist is concrete: before the bassoon matured, indoor ensembles needed a bass line, and no player could sit and play a two-and-a-half-metre tube. Folding is the only way to prise apart "physical length" and "physical size".
| Classification | Value |
|---|---|
| HS class | Aerophone · double reed + conical bore + wind cap + folded bore |
| Sub-type | Vertical · double reed in a wind cap · conical bore folded back and forth inside a short column · finger holes via angled channels to the internal bores · small bell |
| Family | Western · Woodwinds (oboe family, early branch) |
| Bayin | Not applicable — a Chinese system; the racket is outside it |
Structure: a long bore folded into a column
Three points:
1. The wind cap, identical to the crumhorn's — which is why it is quiet, undynamic and nasal. The cap gives this family its temperament. 2. The folded bore. Only three turns are drawn (real instruments often have six to eight); every one of them hides inside this short column. That is the whole secret of its low pitch. 3. Angled finger holes. The hole sits on the outer wall and an angled channel must reach a particular internal bore. This is its unkindest feature: the fingering is exceptionally awkward, and changing to another size moves every hole, so players cannot easily transfer.
Why it must fold: size is not register
This figure is where the whole group lands: straight → one fold → folded to the limit, with the bore length unchanged and the physical size differing eightfold.
The takeaway rule: "how big an instrument is" and "how low it sounds" are two separately designable things. To separate them you need one action — folding.
Range
拉凯特管属气鸣乐器（双簧 + 圆锥管 + 风帽 + 折叠管身）。低音形制约 C2–G3，不同制作者差别较大；风帽限制超吹，单件只负责一段音区，其余音区由成套的其他尺寸承担。有更低的低音形制可到 F1 附近。记谱即实音。
- About C2–G3 on the bass size, with a working register of just C2–C3 — it is a specialist bass instrument, not one that covers a whole range by itself.
- The wind cap blocks overblowing, so each instrument covers a narrow band and the bass part is passed along by consort sizes.
- One counter-intuitive result: because the bore can be folded into a column, the bass sizes are hardly bigger than the top ones — the lower the register, the more turns inside the column, with almost no change in outward size.
Timbre, and how to hear it
Four cues:
1. A low buzzing nasality, thicker than the crumhorn's and closer to a swarm of bees — cap plus long cavity. 2. Not loud, but its low notes carry. Low frequencies are hard to cover up in an ensemble. 3. No dynamics at all. A line must be shaped by pitch and rhythm alone. 4. A slow attack. A long low cavity takes a moment to speak, so it suits held notes and slow lines, not rapid tonguing.
Playing techniques
- Awkward fingering is the main difficulty. Holes sit on both sides of the column and angle in to different bores, so both hands hug the body — and a change of size means learning the holes again.
- Usually held upright against the chest, or rested on the knee. Its shape makes cradling it natural.
- It plays bass lines. In an ensemble it is almost always a held or slow low part, which neatly avoids its two weaknesses: a slow attack and no dynamics.
- It must be shaken out. As with every wind-cap instrument, condensation collects in the cap and the bore.
- Intonation rests on the maker. With no lips on the reed there is no chance to adjust afterwards.
The family
| Instrument | How the bore is folded | Size | Register | Dynamics |
|---|---|---|---|---|
| Racket | into a column (many turns) | tiny | bass | none (wind cap) |
| Crumhorn | once (J) | short | middle–high | none (wind cap) |
| Shawm | not folded | long | middle–high | largely controllable |
| Bassoon | once (U) + keys | medium | bass | controllable |
| Contrabassoon | several folds + keys | medium | very low | controllable |
Read as a history of technology, the table says: "folding" was inherited, "the wind cap" was thrown away. The bassoon and contrabassoon keep the fold, drop the cap and add a key system — gaining both a low register and control. The racket is where that road begins, and it stopped halfway along it.
History
| Period | State |
|---|---|
| 15th–16th c. | appears and flourishes, made in consorts (soprano, alto, bass and lower), used in court and church chamber music |
| late 16th–17th c. | joins the crumhorn in "soft" bands; described and illustrated in treatises such as the *Syntagma Musicum* |
| 17th c. | displaced by the bassoon — also a folded bore, but with keys and without the cap, and far more expressive |
| 18th–19th c. | falls out of use, surviving in documents and plates |
| 20th c. | revived by the early-music movement; modern makers build the various sizes from the surviving plates |
The reason it was superseded is plain: it bundled the right idea, folding, together with the obsolete one, the wind cap. The bassoon took the first and discarded the second. In the spread of a technology, often only half is inherited.
Common misconceptions
- "It is small, so it must be high." Precisely the opposite: it is a bass instrument. The small thing is its body, not its bore — which is the entire point of its existence.
- "It is a small crumhorn." Backwards: it is the crumhorn's bass version, and it solves an extra problem that is purely about space.
- "Folding changes pitch or timbre." Folding changes the route, not the length — the bore is unchanged, so the pitch is too (the bends colour the tone slightly, but their main job is saving room).
- "It is just a curiosity or an antique." It was a mainstay of the Renaissance bass part and the earliest extreme realisation of the folded-bore idea.
- "The bassoon has nothing to do with it." The bassoon inherited exactly the folding idea that it and its contemporaries pioneered.
- "It is the same thing as a bassoon." Two differences decide it: a wind cap and a key system — and those two decide expressiveness, hence which one survived.
Next
The double-reed line of this early group closes here: shawm (unfolded · dynamics) → crumhorn (one fold · no dynamics) → racket (folded to a column · no dynamics · bass), and the three together give the group's two threads: ① who drives the reed decides whether dynamics are possible; ② how the bore is laid out decides how size relates to register.
Now a wholly different thread — strings: the theorbo is a lute with an absurdly long neck for the continuo bass, and the portative organ has to carry a whole organ on one's back. Both ask the same question: to make an instrument portable, what will you give up? :::
