Why Does My Violin Keep Going Out of Tune?
Diagnose and fix a violin that will not hold its tuning, and recognize when to see a luthier instead of continuing to adjust it yourself.
Turn pegs gradually and pay attention to the pitch as you go — turning a peg too quickly or too far can snap a string or, in rare cases, crack the pegbox.

Check how long the strings have been on. Brand-new strings stretch and go flat repeatedly for the first several days of regular play — this is normal and not a fault in the instrument.

Check how the string is wound on the peg. A string wound so it does not touch the wall of the pegbox slips more easily; rewind it so it sits flush against the pegbox wall (the "wedge effect").

Try the "push and turn" technique — gently push the peg inward while turning it, to increase the friction holding it in place.

4. Consider humidity. Pegs (and the wood around them)…
Consider humidity. Pegs (and the wood around them) respond to humidity swings; a peg that only slips in certain seasons, such as during winter heating, is often a humidity issue rather than a defect.

If slipping continues, apply a small amount of purpose-made peg compound to the peg's contact points — not chalk or soap, which are not lasting fixes and can make sticking worse.

6. If a peg still slips after the above,…
If a peg still slips after the above, or feels loose or wobbly in its hole, stop adjusting it yourself and see a luthier — the peg or pegbox likely needs a proper fit adjustment.
What the steps above actually need
Before the shopping list, the distinction that most pages get wrong: peg compound treats FRICTION, not FIT. Luthier Korinthia Klein, writing for The Strad, finds that a sticking peg usually is missing compound — inexpensive instruments often are not treated properly at the factory — but a slipping peg usually is not a compound problem at all. Her three causes for slipping are bad string winding, a worn or badly placed string hole, and a peg that has migrated so far across the pegbox that too little shaft is left to grip. Check the winding first; it is free.

W. E. Hill & Sons Peg Compound
W. E. Hill & Sons
Why it is here: For a peg that is stiff or sticking — the problem compound genuinely fixes.
A stick compound for wooden friction pegs — ebony, rosewood or boxwood — applied to the peg where it contacts the pegbox. This is the right product for a peg that is STIFF or STICKING.
What we cannot tell you: Read the note above before buying: compound treats friction, not fit. Luthier Korinthia Klein, writing for The Strad, identifies the usual causes of a SLIPPING peg as bad string winding, a worn or badly placed string hole, or a peg that has migrated across the pegbox — none of which compound fixes. She also says explicitly not to reach for chalk, and not to force a peg harder into the box.

Ardsley Peg Drops
Ardsley
Why it is here: A liquid alternative aimed at slipping and squeaking pegs, one drop per peg. Note it does not claim to help a sticking peg; these two products are not interchangeable.
A liquid alternative for wooden pegs that slip or squeak, in a small bottle. One drop per peg is typically enough, and the peg only needs loosening and sliding out slightly rather than full removal. Listed for violin, viola, cello and bass.
What we cannot tell you: The retailer page positions this for slipping, squeaking or poorly fitting pegs — note it does not claim to help a STICKING peg, which is the opposite problem and the one Hill compound addresses. The two products are not interchangeable, even though most pages treat all peg products as if they were.

D'Addario Prelude strings
D'Addario
Why it is here: If the strings are old. Johnson String Instrument lists an instrument that will not hold tuning as a reason to replace them, and new strings need days to settle.
A solid steel core student set. D'Addario calls Prelude "the educator's go-to choice for student strings", and it is made for violin, viola, cello and double bass. Worn strings are one of the causes Johnson String Instrument lists for a violin that will not hold its tuning.
Get the right one: Fractional sizes matter — order the size that matches the instrument, not the full size.
What we cannot tell you: Replacement intervals vary by source. Johnson String Instrument says at minimum every 9–12 months; Shar gives 3–4 months for someone practising daily, and cites a luthier's rule of thumb of roughly 120 playing hours. Both note there are too many variables for an exact schedule.

Boveda 2-Way Humidity Control, Small Starter Kit
Boveda
Why it is here: A drying pegbox changes shape, pegs lose grip, and retuning becomes constant. This treats the cause rather than the symptom.
Sealed packs that both absorb and release moisture to hold the case at a set humidity. Boveda states the ideal range for wooden instruments is 40–60% RH and its music packs are 49%. Johnson String Instrument links a drying pegbox directly to pegs losing grip and needing constant retuning — which makes humidity a tuning problem, not just a cracking problem.
Get the right one: The Small kit is for violin and viola. A cello or double bass needs the LARGE kit — getting this wrong is the common mistake.
What we cannot tell you: Boveda recommends refreshing the packs roughly every three months.

Troubleshooting
Pegs slip only when the room is dry or during winter heating season: usually a humidity issue — consider a room humidifier or an in-case violin humidifier rather than repeatedly readjusting the peg. A string was just replaced and will not hold pitch: normal stretch-in behavior, expect it to stabilize within several days. A peg feels loose or wobbly even when pushed firmly inward: needs a proper luthier fit, not a home fix. A fine tuner (rather than a peg) will not hold: fine tuners can also wear out or loosen over time — if adjusting it does not help, that is also a case for a luthier visit.
Common errors
- !Turning pegs too quickly or forcefully; using chalk or soap as a long-term fix instead of proper peg compound; assuming new strings are defective when the flatness is normal stretch-in behavior.
When to stop and see a repair technician
If pegs remain loose after trying the push-and-turn technique and proper peg compound, if a peg or the pegbox shows any crack, or if a fine tuner rather than a peg is the source of the problem and adjusting it does not help, see a luthier rather than continuing to force it.
