How Often Should You Tune a Piano in Chicago? A Technician’s Honest Answer
By Eathan Janney, Founder of Floating Piano Factory · Chicago Piano Care
“How often should I tune my piano?” is the question I hear more than any other from piano owners.
The textbook answer — “twice a year” — is technically correct as a minimum. But it’s also incomplete, and applying it blindly to every piano in every situation leads to instruments that drift further than they should between appointments, owners who are disappointed by the result, and in some cases, real long-term harm to the instrument.
Here is a more honest, detailed answer. I’ll give you the general principles and then specific guidance for Chicago — which has one of the most demanding climates for piano stability in the country.
The Standard Recommendation: Why “Twice a Year” Exists
The Piano Technicians Guild — the professional association for piano technicians in North America — recommends tuning most pianos twice annually. This is grounded in several realities:
Strings stretch and settle. Even in a perfectly stable environment, steel piano strings gradually stretch from their own tension. A freshly tuned piano will be slightly out of tune within weeks of its tuning, simply from string relaxation. Over six months, this drift is noticeable.
Environmental changes affect pitch. As humidity rises and falls, the soundboard expands and contracts, changing string tension. In most climates, this produces a predictable spring-and-fall pitch pattern.
Twice a year catches both seasonal peaks. A tuning in fall (before indoor heating begins and humidity drops) and a tuning in spring (after heating season ends and outdoor humidity rises) catches the piano at each seasonal turning point — the moments when drift has been greatest and a reset is most valuable.
For a piano in a stable, well-humidified environment, receiving moderate use, twice-yearly tuning is genuinely sufficient to maintain it in very good condition.
Chicago is not that environment.
Chicago’s Seasonal Swings: Why the Standard Answer Falls Short
I’ve covered the climate issues in detail in a separate article, but the summary is this: Chicago’s relative humidity swings between approximately 20–30% in winter and 70–80% in summer. That 50-point range is one of the widest of any major North American city.
What this means for tuning frequency:
Without humidity management, a Chicago piano typically needs three tunings per year at minimum. The seasonal peaks in Chicago are more extreme than the national average, and a piano tuned in October will often be significantly flat by February — not just a little off, but noticeably, problematically flat.
With good humidity management — a room humidifier maintained at 45–55% relative humidity, or a piano-specific Dampp-Chaser system installed — twice-yearly tuning is reasonable even in Chicago, because you’re moderating the environmental swings that cause the most dramatic pitch changes.
The calculus is simple: invest in humidity control (inexpensive) and you can maintain the twice-yearly schedule. Skip the humidity control and you’ll either pay for an additional tuning annually or live with an instrument that’s more out of tune than it should be for half the year.
Your Tuning Schedule by Situation
Rather than one blanket answer, here are specific recommendations by situation:
For the typical household piano with moderate use
Without humidity management: 3 times per year. Late October, late January or early February, and late April or early May.
With a good humidifier: Twice per year. Late October and late April are the ideal windows.
For a music teacher’s studio piano
Piano teachers consistently underestimate how much pitch drift a heavily used piano accumulates. An instrument played 6–8 hours daily by multiple students isn’t a “household piano” — it’s a working instrument with working instrument maintenance needs.
Recommendation: Quarterly. Fall (October), winter (January), spring (April), and early summer (June or July). This keeps the instrument consistently reliable for students who are developing their musical ear — and students do internalize the sound of the instrument they practice on.
For a student practicing seriously (1–2 hours daily)
Twice a year is fine if the piano is in a humidified room and conditions are stable. Three times a year — adding a February tuning — is better, especially if the student is working toward auditions, competitions, or recitals.
For a performing musician’s home instrument
If you perform professionally or are an advanced student performing in recitals and competitions, quarterly tuning is the right baseline. Add a tuning before any significant performance or recording if the last service was more than six weeks prior.
For a piano that hasn’t been tuned in more than two years
First, understand that a piano that far out of regular service will need a pitch raise before it can be properly tuned. A pitch raise is a preliminary pass that brings the instrument back to standard pitch (A=440Hz); it stresses the strings and doesn’t produce a stable, fine result. After the pitch raise, a full tuning is done in the same appointment.
The good news: this is routine, not alarming. A pitch raise just takes more time and typically costs more. After the pitch raise and tuning, the instrument needs to be put on a regular maintenance schedule. Your technician may recommend a second tuning 4–8 weeks after the first to stabilize the strings.
For a new piano in its first two years
New piano strings are still stretching and settling. For the first two years, quarterly tuning is standard — and some piano manufacturers actually recommend monthly tuning in the first year. This is especially true for higher-quality instruments where the strings are tensioned to precise and demanding tolerances.
For a piano after a move
Wait 2–4 weeks after any move before tuning. This includes a move across town, a move into a new building, and even a significant repositioning within the same home. The piano needs to acclimate to its new environment’s humidity and temperature. Tuning it immediately after a move produces a tuning that won’t hold.
After the acclimation period: tune it. And then follow whatever schedule is appropriate for the environment.
How to Know If Your Piano Actually Needs Tuning
Even on a regular schedule, there are signs that a piano needs service before its next scheduled appointment:
It sounds noticeably wrong. Even without trained pitch perception, most people can hear when a piano sounds “off” — chords that sound wrong, notes that clash slightly, or a general quality of unpleasantness when playing harmonically. Trust your ear.
Someone with musical training tells you it’s out of tune. A musician who plays violin, guitar, or another instrument with reliable pitch will hear piano pitch problems more readily than a typical listener. Take them seriously.
Playing with other musicians reveals the problem. The most common context in which piano owners discover their instrument is badly out of tune is when they try to play along with another instrument or with recorded music. If you notice a discrepancy, it’s almost certainly the piano.
It’s been more than eight months since the last tuning. In Chicago, eight months without a tuning crosses at least one major seasonal transition. Even a piano that “sounds fine” to untrained ears has likely drifted enough that a professional tuning will produce a noticeable improvement.
The False Economy of Less-Frequent Tuning
Some piano owners reason that if they use the piano less, they can tune it less. This logic is partially correct — an instrument played infrequently drifts less from string wear — but it misses the primary driver of pitch change, which is environmental, not use-based.
A piano sitting silent in a Chicago living room still experiences winter dryness and summer humidity. Its soundboard still contracts and expands. Its strings still change tension with the seasons. A piano that isn’t played much still needs tuning twice a year in Chicago — or three times if it’s not humidified.
The difference is that an unplayed piano may tolerate pitch drift better structurally, since the strings aren’t experiencing the added load of frequent playing. But the pitch drift still happens, and the longer it goes unaddressed, the more severe it becomes.
More importantly: a piano that sits perpetually out of tune is a piano that gradually trains its owner to accept substandard sound. Children learning on an out-of-tune piano develop inaccurate pitch perception. Adults playing for pleasure find it subtly less satisfying. The instrument’s potential is unrealized, year after year, because the maintenance cost was skipped.
A Note on Pitch Stability Between Tunings
After a professional tuning, how well the piano holds pitch is a function of several variables:
The quality of the previous tuning. A skilled technician will “set” each pin in a way that holds — the pin is turned past the target position and then backed down to it, creating a configuration that resists slippage. An inexperienced or rushed technician may not take this step, and the tuning will slip faster.
The condition of the pinblock. In older pianos or those with significant wear, tuning pins may sit loosely in the pinblock and slip after tuning. This is a more serious mechanical issue that a technician should identify and advise on.
Environmental stability. Even a perfectly executed tuning will drift faster in an unstable humidity environment. This is the strongest argument for humidification.
String condition. Very old strings have less elasticity and are less able to hold a tuning. In some instruments, string replacement is a cost-effective investment in tuning stability.
Bottom Line
In Chicago, tune your piano at minimum twice per year — ideally in late October and late April. Add a February or March tuning if the piano receives daily use, if a teacher or serious student plays it, or if you’ve noticed significant pitch drift. For high-use instruments or demanding players, quarterly is the right standard.
Invest in humidity management. A hygrometer costs $15. A room humidifier costs $60–150 for a quality unit. A Dampp-Chaser system professionally installed costs a few hundred dollars. These are investments that protect an asset worth anywhere from a few hundred to several hundred thousand dollars.
And find a technician you trust and stick with them. The technician who knows your specific instrument — its idiosyncrasies, its history, its response — does better work than one starting from scratch each visit.
