Taking Care of Your Piano
Why Do Pianos Go Out of Tune?
When a piano is new, the strings stretch and go out of tune very quickly. (If you play the guitar, you
know how often a new set of strings must be tuned before it they settle.) That is why most technicians
recommend at least two tunings in the first year you own a piano. Regular tuning is most important in these
early years, when the strings are stabilizing. If you don’t tune the piano in the first few years, the strings
will stabilize at the wrong pitch, and it will be much harder to bring the piano up to the correct pitch.
Once the strings have stabilized, tuning is most affected by humidity changes. In fact, when a piano
goes out of tune during moving, it’s often because it’s been through a humidity change! The structure of a
piano may be quite massive, but much of it is wood. Whenever the humidity changes, the wood either
expands or contracts. Any little movement of the soundboard tends to change the tension on the strings,
and thus the pitch. When humidity goes up, the pitch goes up; when humidity goes down, pitch goes down.
Be careful of where humid or dry air may come from. The old rule about placing the piano on an
inside wall has some truth to it, but it matters much less in new, well-insulated homes. Look out for heating
vents. And please, don’t leave a window or door open near the piano. That can put a piano out of tune in
minutes. If your piano is in a particularly drafty room, like a church or auditorium, you may need a
humidity control system. It’s expensive, but it definitely will make your tunings and all the wooden parts
last longer.
Please Don’t...
Don’t put anything on the music desk (of a grand piano), except music. Pencils, paper clips, coins, and
index cards can fall into the piano and cause problems.
When you hear a buzz while playing the piano, make sure that it is not some external object that you
are hearing. Remove everything from the piano and try again.
Wooden Caster Cups
If you have a grand piano, you probably have noticed what the wheels do to your rug or wooden
floor. The solution is caster cups. In the past, caster cups have been made of plastic (which you actually
may prefer if your piano has a shiny polyester finish.) In recent years I’ve started offering wooden ones too. They come in satin black or
mahogany finish. The plastic ones come in black or brown. Either way, it’s $20.00 for a set of three.
Humidity Control Systems
Most homes these days are pretty well insulated. But if you have a special situation like a church,
school multi-purpose room, or just a drafty old house, you may need special help to avoid the harmful
effects of excess changes in humidity. The Dampp-Chaser humidity control systems are the industry
standard. The full system, including dehumidifier (drying bar), humidifier, humidistat, and low water
warning light, is $200.00 installed for uprights and $250.00 installed for grands. For most situations,
though, the dehumidifier and humidistat alone are sufficient. That is $150.00 installed in either grand or
upright.

How Can You Learn More About Pianos?
The best book on pianos written for the non-professional is undoubtedly The Piano Book by Larry
Fine. It was first published only three years ago and already is in its second printing. It is primarily written
for people who are planning to buy a piano, but it's also great just for learning how pianos work and what
piano technicians do. You can look for it at the library, at any large bookstore, or order it directly from
Brookside Press, P.O. Box 178, Jamaica Plain, MA 02130. Call (800) 545-2022 for the current price.
The Piano Technician’s Guild is an international association of piano technicians dedicated to
education. It administers tests covering tuning, repair, and general knowledge of the piano. When a
member passes all three tests, he or she receives the title of Registered Craftsman. When you’re looking for
a piano technician, look for a Registered Craftsman Member of the Piano Technician’s Guild. It’s the only
objective standard of competence that I know of in this industry.
