How Often Should I Have My Piano Tuned?
How Often Should I Tune My Piano?
If you own a piano in Ireland, a good rule of thumb is to have it tuned every six to twelve months.
But there is no single schedule that is right for every piano.
A piano that is played every day by a professional musician, for example, has very different needs from a piano that sits in a family home and is played occasionally. A piano in a stable, well-controlled environment will behave differently from one beside a radiator, fireplace or window. And a brand-new piano can actually need more frequent tuning than an older instrument.
As a seventh-generation piano tuner and registered piano technician with the Piano Technicians Guild, I have worked with thousands of pianos in Ireland, from new and second-hand instruments to restored pianos, concert instruments and family heirlooms.
My experience has taught me that the best answer to "How often should I tune my piano?" is not simply a number of months.
You should tune your piano according to how it is used, where it is kept and how well it is holding its pitch.
How often should a piano be tuned?
For the average piano in an Irish home, I would generally recommend one or two tunings per year.
That six-to-twelve-month window allows us to account for some of the biggest variables affecting a piano:
How often it is played
The age of the piano
The quality of its construction
Where it is located in the home
Temperature fluctuations
Humidity
Whether it is new or recently restored
How accurately it has been maintained in the past
Ireland's changing weather makes the environment particularly important.
Pianos are made from a combination of materials including wood, felt, glue and steel. These materials respond to changes in temperature and humidity by expanding and contracting. As they move, the tension of the strings changes, and therefore so does the pitch.
This is one of the reasons an Irish piano may need attention more frequently than a piano kept in a very stable environment.
Some pianos need tuning much more often
The six-to-twelve-month recommendation is for a typical domestic piano. There are plenty of situations where I would recommend tuning more frequently.
Professional musicians
A professional pianist should generally have their piano tuned much more regularly.
When you spend hours listening to and playing an instrument, your ear becomes accustomed to hearing what a properly tuned piano sounds like. A piano that is only slightly out of tune to the casual listener can be distracting to someone who plays professionally.
Piano students and teachers
I would also recommend more frequent tuning for piano students and teachers.
There is a useful feedback loop involved in learning music. When a student hears their piano sounding like their teacher's piano, the piano in the conservatory, or the recording they are learning from, they get a much clearer auditory reference for what they are trying to achieve.
If the instrument is badly out of tune, that feedback becomes less useful.
There is also something very encouraging about sitting at a piano that sounds like the instruments played by professionals. When your playing sounds more like the recording you are learning, it can make you feel that you are getting closer to the real thing.
Frequently played family pianos
A family piano that is played frequently should also be tuned more often than one that is rarely touched.
The more an instrument is used, the more frequently its condition should be assessed.
That does not necessarily mean that a piano needs tuning every time someone plays it. It means that its maintenance schedule should reflect its actual use.
New pianos need more attention, not less!
One of the most common misconceptions I encounter is that a new, expensive or high-quality piano should need less tuning.
In reality, a new piano can require more attention during its early years.
A new piano is going through a break-in period. The strings, pins, soundboard and other components are settling into their working positions, and the instrument can move considerably during its first few years.
Manufacturers commonly recommend several tunings per year during the first two or three years of a piano's life.
The same principle applies to a recently restored piano.
If a piano has been fitted with a new pinblock, new strings, new pins, or a combination of these, it will need time and attention to stabilise.
In other words, buying a new or newly restored piano does not mean you can forget about tuning for several years.
What about hotels, venues and performance pianos?
The answer here depends almost entirely on usage.
I recently encountered a particularly extreme example: a grand piano in a hotel orangery.
It was being played approximately once a week, but it was situated in an environment with significant temperature and humidity fluctuations. From what I could establish, the piano had last been tuned six years previously.
The condition of the piano reflected that neglect.
It was essentially unplayable—not just in terms of tuning, but also in its touch and tone.
This is an extreme example, but it illustrates an important principle:
The environment and usage of a piano have to be considered together.
A hotel piano being played once a week might reasonably be tuned quarterly, particularly if its environment is not perfectly stable.
At high-end venues, pianos may be tuned twice before a performance and sometimes again afterwards, allowing the technician to stabilise the instrument following the demands of a performance.
What happens if you don't tune your piano?
Many piano owners wait until their piano sounds terrible before calling a technician.
By that point, what should have been a routine tuning can sometimes become remedial work.
The first thing that usually becomes noticeable is the unisons.
A piano note is produced by multiple strings sounding together. When those strings drift apart, you can hear a kind of sourness or beating between them.
At first, this may be subtle.
Over time, however, the sound can become unmistakable—the sort of exaggerated, honky-tonk sound you might associate with an old Western film.
After the unisons, the octaves become increasingly noticeable. The treble is particularly susceptible to falling flat because of the high tension on its shorter strings.
Eventually, the piano's overall pitch can fall significantly below concert pitch.
Concert pitch is generally A440, meaning that the A above middle C is tuned to 440 Hz.
A piano that has dropped significantly below this pitch creates a practical problem. You may no longer be able to play along comfortably with recordings, and other instruments may have to accommodate the piano rather than the other way around.
That can be particularly problematic with instruments that cannot easily be retuned to accommodate a piano.
There can also be a technical cost…
The problem with leaving a piano for years without tuning is not simply that it sounds bad.
As the overall pitch drops, the tension throughout the instrument changes. The plate, soundboard and pinblock are no longer operating under the conditions for which the instrument was designed.
This can have a domino effect.
Changes in tension can contribute to changes in regulation and tone, and what began as a straightforward maintenance visit can eventually require more extensive and expensive remedial work.
This is why regular tuning is maintenance rather than simply cosmetic work.
How can I tell if my piano needs tuning?
You don't need to be a professional musician to hear the early signs.
One of the easiest things to listen for is a single note.
Play a note slowly and listen carefully. Does it sound clean and unified, or can you hear a slight sourness or a pulsing, beating quality?
Those beats are the individual strings of the unison interacting because they are no longer at exactly the same pitch.
You can also listen to octaves.
A well-tuned octave should sound clear and cohesive. If the relationship between the two notes sounds noticeably rough or uncomfortable, the piano may be drifting out of tune.
But tuning isn't the only thing to listen for.
If the touch of the piano changes, that can be a sign that it needs servicing. Perhaps the keys feel unusually heavy or unusually light. Perhaps some notes feel different from others, or one section of the keyboard feels different from another.
Changes in tone are another warning sign.
A piano that sounds uneven, dull, harsh or inconsistent may need more than a tuning.
This is where it is important to understand the difference between tuning and servicing.
A tuning brings the pitches of the piano into the correct relationship with one another. A service can involve regulation, repairs, adjustments and other work required to restore the instrument's touch and tone.
Most technicians will address very minor repairs or regulation as part of a tuning, but a full service is a different proposition.
Where should you put a piano in your home?
The location of a piano can make a surprising difference to how well it holds its tuning.
For an upright piano, I would ideally place it against an interior wall, towards the centre of the home.
For a grand piano, I would avoid placing it where it is exposed to significant direct sunlight, particularly through a south-facing window.
The goal is stability.
Radiators, fireplaces and direct sunlight are all enemies of a stable piano. Exterior walls can also expose the instrument to greater temperature fluctuations.
Conservatories and orangeries can be particularly challenging environments.
That hotel grand in the orangery is a good example of why.
The more the environment fluctuates, the more the piano's materials move—and the more difficult it becomes for the instrument to maintain a stable tuning.
Does my piano need humidity control?
Not necessarily.
In many homes, sensible environmental control and good placement are enough to keep a piano relatively stable.
There are, however, measures that can provide additional protection.
A Dampp-Chaser system is a well-known and proven method of helping to control the piano's immediate environment.
There are also simpler measures that can sometimes help. A bowl of water can be placed inside a piano to increase the local humidity, although this should obviously be done carefully to avoid spills or introducing unnecessary moisture to the instrument.
The most important thing is not to become obsessed with achieving a particular humidity number while ignoring the fundamentals.
Keep the piano away from extreme environmental changes wherever possible.
Does playing the piano make it go out of tune?
Playing a piano is certainly one factor, but it is not the only factor—and it isn't necessarily the biggest one.
A piano being played heavily by a professional will require more attention than one being played occasionally by a child.
But environmental stability can be equally important.
I've had pianos scheduled for tuning every six months where the actual usage was very light. In some cases, the players were young children who weren't practising particularly often or playing with much force.
These were also relatively new, premium-quality pianos kept in stable environments.
So while a six-month schedule is perfectly reasonable, the piano itself may tell us that it could comfortably go longer.
We are all guilty of shirking our practice duties every now and then!
Don't wait until the piano sounds terrible!
Another common mistake is assuming that if only a few notes sound out of tune, only those notes need fixing.
That isn't generally how it works.
If individual notes have become starkly out of tune, it is a good indication that the entire piano has been drifting.
Trying to correct only the notes that are obviously wrong is a little like looking at a clock and replacing only the hands because they are showing the wrong time.
The whole instrument needs to be assessed.
There is also a psychological element to this.
Like watching a child or a pet grow up, you don't necessarily notice small changes from one day to the next. But over a period of years, those changes become obvious.
The same thing happens with a piano.
You sit down and play it every week, gradually becoming accustomed to the way it sounds and feels. Then a visiting relative sits down and immediately notices that something doesn't sound right.
Regular maintenance prevents that gradual decline from becoming your new normal.
How often should your piano be tuned?
As a starting point:
Occasionally played home piano: Every 9–12 months
Regularly played family piano: Every 6 months
Professional pianist: More frequently, depending on use
Piano student: More frequently, depending on practice
Piano teacher: More frequently
New piano: Up to 4 times a year initially
Newly restored piano: Several tunings during stabilisation
Hotel piano played weekly: Approximately every 3 months
High-end performance venue: Before and/or after every performance
These are starting points rather than hard rules.
The right schedule depends on the particular piano.
An older, well-maintained piano in a stable environment may hold its tuning surprisingly well. A newer piano in an unstable environment may require considerably more attention.
The real value of regular piano maintenance
There is another reason I encourage owners to maintain their pianos properly.
Pianos can last an extraordinarily long time.
Many pianos built during the last two centuries are still functioning instruments today. They have survived because successive owners cared enough about them to maintain them properly and invest in their upkeep.
As a seventh-generation piano technician, this is something I have experienced in a particularly tangible way.
I have seen pianos where my father, his father, and his father before him have left consecutive signatures on the piano keys, recording their service history.
You can literally see generations of technicians maintaining the same instrument.
That is what a piano can become.
It can be bought by one generation, played by another, passed to children and grandchildren, restored when necessary, tuned throughout its life and continue making music long after its original owner is gone.
When properly maintained, a piano can outlive us all.
So if you're wondering how often you should tune your piano, don't think only about whether it sounds out of tune today.
Think about the instrument you want to hand to the next person.
A piano gives an enormous amount of joy back to the people who play it. Regular tuning and proper maintenance are simply part of returning that favour.
