Oud Strings and Care
An oud (عود) is a thin wooden bowl under constant string pull. How you string it, how you treat the pegs, and how you live with air conditioning and summer heat will affect the instrument more than most accessories. This article covers string types, a careful way to change them, peg habits, climate (with the Gulf in mind), cleaning, travel, and when to stop DIY and see a luthier. Tensions, gauges, and materials vary by maker and by whether the oud is Arabic, Turkish, or another build. When in doubt, copy what is already on a healthy instrument of the same type, or ask the person who built or sold it.
String types
A typical set mixes plain trebles and wound basses.
- Nylon (or similar plain synthetics) on the higher courses. Familiar, warm, widely available. They stretch a lot when new.
- Wound basses — a metal winding over a core — on the lower courses. They give the round thump that people hear as “oud bass”. If the winding frays, the string is finished.
- Fluorocarbon (often discussed as a brighter, denser treble option than nylon). Some players like the focus and quicker response; some find it sharp for their bowl. It is a taste and tension choice, not a moral upgrade.
Sets are sold for Arabic or Turkish scale and for lighter or heavier feel. Tension here is qualitative: too light, and the string feels flabby, wandering in pitch under a firm risha (ريشة); too heavy, and the soundboard and the left hand both work too hard, with a risk to a light student top. Do not put a very high-tension set on a small or lightly built oud because a forum said it was “more professional”. Eleven-string Arabic sets and twelve-string Turkish sets are not interchangeable without checking length and which courses are doubled.
How often to change strings
There is no universal calendar. Trebles that sound dull, will not stay in tune after they should have settled, or look worn, are candidates. Wound strings that have gone false or whose wrap is loose should go. Sweaty hands, daily practice, and coastal air all shorten life. Change a whole set if several strings are old, so the instrument does not mix two eras of stretch and tone. Change a single string if you break one on an otherwise fresh set. Keep a spare set in the case, not in a hot car.
Changing strings, step by step
Work in a quiet, well-lit place. Have cutters, your new set, and a cloth. Many players change one course at a time so the soundboard never sits fully slack. On a lightly built oud, avoiding a sudden total loss of tension is the gentler habit unless a luthier has told you otherwise.
- Study the old winding at the peg and at the bridge before you cut anything. Photograph both ends of one course.
- Slacken and remove one course (both strings of a pair, or the single bass). Do not let a live string-end flick the soundboard or your eye.
- Bridge tie. Traditional ties loop through the bridge holes and lock with a knot so the string cannot slip. Copy the old knot. The string should leave the front of the bridge toward the nut without tearing the wood. If a hole is sharp, stop and see a luthier.
- Peg winding. Thread through the peg hole, leave a short tongue, and wind so coils sit neatly toward the thick end of the peg. Wind in the direction that pulls the peg inward as you tune up. Too many overlapping coils cause slipping; too few and the string pops out of the hole.
- Bring up to pitch slowly. Stretch the string with a gentle pull away from the soundboard, retune, repeat. Do not crank a long way sharp to “get it over with”.
- Tune unisons on the pair, then move to the next course.
If you have never tied a lute-style bridge knot, practise with a dead string or have a teacher do the first set while you watch. A bad knot that slips will slap the soundboard. Trim excess so the pegbox does not look like a thicket, leaving a little spare in case a winding fails.
Peg care
Friction pegs need a fit, not force. If a peg slips, push in slightly as you turn. If it seizes, twist it out with steady rotation, never a sideways bend on the pegbox. Peg compound or chalk is a traditional aid used sparingly. If the peg still will not hold, the hole or the peg may need dressing by someone who owns the right reamer — not sandpaper in the kitchen. Avoid leaving the oud where pegs dry out and shrink (aggressive air conditioning) or swell (damp storage). Geared pegs need small turns and a technician if a gear slips; do not mix care advice blindly between friction and geared systems.
Humidity and heat in a Gulf climate
Wood likes gradual change. Two local risks matter more than folklore:
- Air conditioning dries the room. A soundboard can shrink, seams can open, and pegs can slip. Instruments that lived in a humid coastal evening then sleep in a cold, dry bedroom are under stress.
- Cars and sun. A closed car in summer can wreck glue, finish, and strings. Do not leave the oud in the vehicle “for an hour” while you shop. Direct sun on the soundboard is also unwise.
A common guidance range for many wooden instruments is roughly 40–60% relative humidity. That is typical advice, not a laboratory specification for your particular bowl. A small hygrometer in the room or case tells you more than guessing. If the air is very dry, a case humidifier made for instruments — used according to its instructions, never dripping onto the soundboard — can help. Do not put a glass of water in the case or drape wet towels on the oud. If you move between a dry indoor life and a humid outdoor performance, give the instrument time in its case in the new space before you tune to concert pitch and play hard.
Cleaning and travel
After playing, wipe sweat from the soundboard, neck, and strings with a soft dry cloth. Avoid household polish, alcohol, and kitchen cleaners on the finish and on the rosette. Do not rest drinks on the instrument, and keep the case free of sand.
Use a case that protects the bowl and the bent pegbox. For car travel, use the passenger cabin with air moving, not the boot in the sun. For flights, a proper hard case and the airline’s instrument policy matter; cabin is safer than a hot hold when you have the choice, but rules differ. Do not slacken strings before a short drive across town unless a luthier has recommended it for a specific trip.
When to see a luthier
Stop home repairs and seek a repairer who knows ouds or at least lutes when you see a crack in the soundboard, especially near the bridge; a rib coming open; a bridge lifting; a pegbox crack or a peg that has been forced; buzzes that rattle from inside; or a neck that looks twisted. A set-up — action, nut slots, peg fit — is a reasonable professional job on a new or newly bought oud. Describe the climate you live in; a repairer in a dry inland city and one on the coast may give different humidity advice for the same bowl.
Next steps
Once strings hold pitch, return to a tuning routine that takes minutes rather than half the evening. If you are still choosing an instrument, the buyer’s guide on cracks, pegs, and action will make more sense after you have changed a set yourself. Keep daily practice short enough that you still have the patience to pack the oud away from the air-con vent and the car.

Oud practice differs between teachers, schools and regions. Treat this lesson as general guidance, and follow your own teacher where the two disagree. If playing causes pain, stop and get advice from a qualified professional.
