COMPLETE GUIDE TO MAINTAINING A QANUN
The Historical and Morphological Foundations of the Qanun
The qanun stands as the quintessential chordophone of the Middle Eastern, North African, and Mediterranean musical landscapes, serving as the foundational reference for pitch and modal structure within the maqam system. Etymologically derived from the Ancient Greek term “kanōn,” signifying a rule, law, or principle, the instrument has historically functioned as the arbiter of tuning for ensembles. The organological lineage of the qanun is remarkably ancient, with its earliest identifiable ancestor depicted on an ivory box from the Nimrud site in the Old Assyrian Empire, dating to approximately the nineteenth century BC. This historical trajectory suggests that the qanun is a direct descendant of the large zithers utilized in Mesopotamia, evolving through various iterations across Sumerian, Persian, and Ancient Egyptian civilizations before achieving its modern trapezoidal form.
The structural evolution of the instrument underwent a significant transformation in the nineteenth century, largely attributed to the Syrian musician Omer Efendi, who is credited with introducing the sophisticated lever mechanism to Istanbul during the reign of Sultan Mahmud II. This innovation allowed for the rapid and precise microtonal adjustments that define contemporary Turkish and Arabic art music. Prior to this period, players often relied on fingernail pressure at the string extremities to achieve modulations—a technique that was cumbersome and limited the harmonic complexity of the repertoire.

Material Science and Anatomical Composition
The qanun is a masterpiece of woodworking, requiring a meticulous selection of tonewoods to balance the extreme tension of up to 81 strings while ensuring acoustic resonance. The soundboard, or face, is traditionally crafted from spruce or plane tree wood, chosen for its high strength-to-weight ratio and ability to transmit vibrations efficiently. The lower base and sides are typically constructed from denser hardwoods such as walnut, maple, or mahogany, which provide the structural rigidity necessary to resist the compressive force of the bridge and the torsional strain of the tuning pegs.
The bridge, often carved from bone or high-density synthetic materials, does not rest directly on the wooden soundboard. Instead, it sits upon a series of skin panels, traditionally made from fish skin or cowhide, which are inset into the soundboard. This specific “bridge-on-skin” configuration is what imparts the qanun its characteristic “earthy” yet “angelic” timbre, analogous to the resonance of a banjo drum but with a much wider tonal horizon.
The Mandal System: Physics of Microtonality
Underneath each course of strings lies the mandal (Turkish) or orab (Arabic) system—a series of small metallic levers that allow the performer to alter the effective length of the string, thereby shifting the pitch by increments known as commas. These levers are usually made of alpaca, brass, or steel. In the Turkish tradition, the semitone is theoretically divided into six equal parts, allowing for a total of 72 divisions within an octave, though makers only install the mandals required for the most common maqamat to maintain playability and avoid crowding.
The mechanical integrity of the mandal is paramount. Each lever must shift smoothly without producing clicks, rattles, or ticking noises, which would be amplified by the soundboard and captured in studio recording environments. Misaligned mandals or loose mounting screws are common causes of tuning instability and unwanted mechanical artifacts.
Environmental Physics: The Impact of Humidity and Temperature
As an instrument comprised primarily of organic, hygroscopic materials, the qanun is in a state of constant equilibrium with its environment. Wood, skin, and glue joints expand and contract in response to changes in relative humidity (RH) and temperature, necessitating strict environmental controls to prevent structural failure.
Hygroscopic Stress and Structural Integrity
The ideal environment for qanun storage and performance is a relative humidity level between 40% and 60%. When the humidity drops below 40%, particularly during winter months or in arid climates, the wood loses internal moisture and shrinks. Because the frame and soundboard are often made of different woods with grain running in opposing directions, this shrinkage creates significant internal stress. This often manifests as:
- Soundboard Cracks: The wood fibers pull apart, typically along the grain lines.
- Open Seams: The hide glue used in traditional construction becomes brittle and fails, causing the joints between the face, base, and sides to separate.
- Slipping Pegs: The tuning pegs, which rely on friction, shrink in their holes and can no longer hold the tension of the strings, causing the instrument to spontaneously detune or “pop”.
Conversely, excessive humidity (above 60%) causes the wood and skin to absorb moisture. This leads to the swelling of the soundboard, which can alter the bridge height and compromise intonation. More critically, high humidity causes the skin panels to lose tension and “sag,” resulting in a dull, muted tone and making the mandal system difficult to operate as the strings may no longer clear the levers properly.
Thermal Shock and Finish Preservation
Rapid temperature fluctuations, known as thermal shock, pose a direct threat to the instrument’s finish and structural bonds. For instance, moving a qanun from a cold exterior environment to a heated performance hall can cause the finish—especially if it is a traditional French polish or shellac—to “check” or develop a network of fine cracks. Professionals are advised to keep the instrument in its padded hard case during transport to serve as a thermal buffer, allowing the instrument to acclimate slowly to new environments.
| Parameter | Optimal Range | Mitigation Strategies |
| Relative Humidity | 40% – 60% | Room humidifiers, case humidifiers (Stretto/Dampit), silica gel |
| Temperature | 18°C – 24°C | Climate control, avoiding direct sunlight/radiators |
| Air Flow | Low / Controlled | Keeping instrument in case when not in use |
Preventative Maintenance and Daily Hygiene
The longevity of a qanun is directly proportional to the consistency of its daily care. Human skin oils, sweat, and environmental dust are the primary agents of surface degradation.
Surface and String Decontamination
Following every use, the instrument must be wiped down with a high-quality, dry microfiber cloth. This action removes the acidic oils and salts deposited by the hands, which can dull the finish and corrode the metal strings. For the strings specifically, regular cleaning prevents the buildup of “gunk” that alters the string’s mass and frequency response, leading to what musicians refer to as “false” strings that cannot be accurately tuned.
In cases of deep interior cleaning, an expert technique involves the use of uncooked rice. Pouring dry rice into the soundholes and gently shaking the instrument allows the rice to collect dust bunnies and debris into lumps, which can then be removed with tweezers or by inverting the instrument. This practice is essential for maintaining the clarity of the instrument’s internal acoustic chamber.
Handling and Ergonomics
To prevent mechanical damage, the qanun should always be lifted by its neck or stable frame points, never by the delicate mandal system or the bridge. Furthermore, players are advised to wash their hands thoroughly before playing to minimize the transfer of oils and food particles, which is particularly critical for the health of the skin panels.
Technical Maintenance of Friction Components: Pegs and Mandals
The qanun’s tuning system relies on friction pegs, typically made of ebony or rosewood, which are seated in a pegbox. Maintaining the delicate balance of friction is one of the most challenging aspects of qanun care.
Troubleshooting Slipping and Sticking Pegs
Tuning pegs often fail due to changes in humidity or wear on the contact surfaces. If a peg slips, it indicates insufficient friction between the peg and the hole. This can be remedied by:
- Chalk or Rosin: Applying blackboard chalk or a small amount of rosin powder to the peg’s contact surface increases grip.
- Peg Compound: Using a commercial peg paste (often called “peg dope”) can provide a controlled amount of friction while allowing smooth rotation.
- Proper Winding: Ensuring that the string is wound close to the pegbox wall creates a slight lateral pressure that helps “lock” the peg in place.
If a peg is sticking or difficult to turn, it may be due to high humidity causing the wood to swell or a buildup of old lubricant. In such cases, cleaning the peg and the hole with a small amount of naphtha or lighter fluid followed by a light application of peg compound is recommended. For extremely stubborn pegs, a drop of 3-in-1 oil or olive oil on the fingers can sometimes revitalize the wood, though this must be used sparingly to avoid saturating the grain.
Mandal Adjustment and Noise Mitigation
The mandal levers are subject to constant mechanical use and may develop buzzing or rattling over time. This is usually the result of the mounting screw vibrating loose from the wooden soundboard.
- Tightening Protocols: Using a precision screwdriver (often a 5/64″ hex or a small flathead), the screw should be tightened until it is snug. However, because the wood underneath (linden or plane tree) is relatively soft, over-tightening can strip the threads.
- Thread Restoration: If a screw hole is stripped, a traditional luthier’s fix involves inserting a sliver of wood or a toothpick with a drop of wood glue into the hole to provide new material for the screw to bite into.
- Lubrication: A tiny amount of paraffin wax or specialized instrument grease on the mandal’s pivot point can eliminate mechanical clicks during operation.
The Art and Science of Skin Panel Restoration
The skin panels (deri) are the most fragile components of the qanun and are often the first to require major repair. They are prone to warping if they get wet and will eventually lose their “snap” after years of supporting the bridge.
The Replacement Process: A Master Luthier’s Protocol
Replacing the skin panels is a complex procedure that involves disassembling the primary acoustic components.
- De-stringing: Strings must be removed carefully. If they are to be reused, they should be labeled and kept in order.
- Removal of Old Components: The bridge and any ornamental trim are removed. The old skin is cut away, and the remaining glue is softened using a heat gun or a hair dryer on a high-heat, low-speed setting.
- Surface Refinement: All old glue residue must be scraped off with a chisel or razor. The surface is then sanded with 220-grit emery cloth to ensure a fresh, rough surface for the new adhesive to bond to.
- Skin Preparation: New cow or fish skin is soaked in cool water for 15–20 minutes to achieve maximum pliability. It is then blotted between towels to remove surface moisture but must remain damp during installation.
- Adhesion and Tensioning: A high-quality wood glue or traditional wheat paste is applied to the frame. The skin is stretched over the opening and secured with drapery pins placed approximately every inch. The skin must dry naturally; artificial heat sources will cause it to dry unevenly and potentially crack.
- The “Sinking” of the Bridge: Once the skin is dry and sounds like a drum when tapped, the bridge is repositioned. As new strings are installed and tuned, the skin will “sink” slightly. Experts recommend periodically wetting the skin lightly during the first tuning to allow it to stretch without tearing under the sudden increase in pressure.
Advanced String Management: Material Selection and Tuning Memory
Qanun strings have evolved from traditional gut to high-performance synthetics. Modern professional sets typically combine clear nylon or fluorocarbon (PVF) for the treble and mid-range with silver or bronze-wound nylon for the bass courses.
Selection Criteria for Professionals
| Material | Tonal Characteristics | Durability / Stability |
| Nylon | Warm, mellow, traditional | Sensitive to temperature changes |
| Fluorocarbon (PVF) | Bright, crisp, high projection | Higher tension, excellent pitch retention |
| Bronze-Wound | Deep, resonant lows | Subject to oxidation; needs regular cleaning |
The “Memory” of the String and Tuning Protocols
Strings possess a physical property often described as “memory,” where the material settles into a specific molecular orientation at a given tension. If a qanun is left untuned or the tension is significantly lowered, the strings will require several days of frequent tuning to regain stability.
When replacing strings, the knot at the tailpiece is critical. For the thin treble strings, a double overhead knot or a fisherman’s knot is used to ensure the string does not slip through the hole. The string is then passed through the mandal system and wound onto the peg. During the winding process, the player must maintain tension by hand and push the peg inward while turning to ensure a secure friction lock.
Troubleshooting Common Acoustic Artifacts
A qanun in poor repair often suffers from “buzzing” sounds that can be difficult to diagnose. A systematic approach to troubleshooting is required.
- String Buzzing: This usually occurs at the bridge or the nut (the point where the string enters the mandal bed). If the slot is too wide or has a burr, the string will vibrate against the walls. Light sanding of the slot or applying a small amount of graphite from a pencil can often resolve this.
- Mandal Ringing: If a mandal is not fully engaged or is slightly loose, it can vibrate in sympathy with certain frequencies. Checking the tightness of the mandal screws is the first step.
- Bridge Unsteadiness: The bridge must remain perfectly perpendicular to the skin. If it leans forward or backward, the intonation will be compromised, and the feet of the bridge may no longer make full contact with the skin, causing a “thin” sound or buzz.
- Tailpiece Vibration: Loose parts at the tailpiece or the ornamental “kafes” (rosettes) can rattle. These can be secured with a tiny drop of superglue.
