Does your piano feel sluggish? Does it not feel and play as precisely and evenly as it used to? Chances are it needs some adjustments to the moving parts of the piano called the action. This is known as regulation and is part of the regular maintenance every piano needs, but most piano owners aren’t even aware of its importance. PianoCraft Service’s expert technicians can regulate your piano to feel and respond better than ever! If your piano hasn’t had any regulation done recently (or ever!) contact us to make an appointment or with any questions regarding this critical part of maintaining your piano’s health and performance. >> more info

If your piano doesn’t have an even sound note to note, or if it sounds overly bright and tinny, chances are it needs to be voiced. As your piano gets played, the felt of the hammers are constantly hitting the steel of the strings. The felt gets compacted and harder in a manner that makes your piano sound uneven and unpleasant. PianoCraft Service’s expert technicians can “voice” your piano to sound beautifully warm and rich, and even from note to note. This is a very important part of normal maintenance for your piano that often gets neglected. People are often amazed at how much better their piano sounds after it is properly voiced. If your piano hasn’t been voiced recently (or ever!) contact us to make an appointment or with any questions regarding this critical part of maintaining your piano’s health and performance. >> more info

Climate Control
The Washington DC climate is hot and humid in the summer and cold and dry in the winter. These climate extremes play havoc on the wood of your piano, causing it to go out of tune and out of regulation and the swings in humidity may even cause cracks in the soundboard! PianoCraft Service can install systems that will protect your piano from the harsh Washington DC climate and keep it sounding and playing better and lasting longer! Protect your investment and contact PianoCraft Service with any question regarding climate control for your piano. >> more info


Tunings are considered a basic first step in piano care. You’ll find the difference in playing an in-tune piano is so great you’ll understand why people often think primarily of tuning when they think of standard upkeep. However, it’s important to request that your technician care for your piano’s regulation and voicing, as well.

Pianos are tuned to maintain the pitch, stability, and pitch balance of the instrument. Regular service visits help the piano last longer and makes it a wonderful, musical experience to play. The Piano Technician’s Guild recommends at least two to four tunings per year for a piano under general use. Most performance instruments are tuned more often, usually before each concert as well as throughout the off-season.

How Should I Take Care of My Piano?

If you want to minimize the number of tunings necessary, the best times to have your piano tuned are after the air conditioning has been turned on in the summer and after the heat has been turned on in the winter. Tunings done at these times will be the most stable. In the summer the pitch will rise and in the winter the pitch will fall. The changing pitch is particularly problematic because the drift is not even across the keyboard.

If you’re having your piano tuned once a year it will not suffer significant damage – even though it won’t sound good – but a piano that is left to sit for many years, even one that’s not being played, will drift much farther out of pitch than is healthy for a piano. If this is allowed to happen it will take a series of pitch raise tuning service visits to get the piano back to where it had been before the neglect.


The piano’s several thousand moving parts, known as the action, contain many wood, felt, and leather components. These change over time due to use, wear, and changes in temperature and humidity.

For example, the key height will change as the keys rock up and down on a small stack of felt and paper spacers called punchings. Over time, the keys will sag as the punchings compact. This causes a shorter travel distance at the front of the key, which causes insufficient travel at the back of the key to complete the playing cycle. The result is reduced power, a nonstandard feel to the pianist, loss of control at low volumes, and hammer bouncing, called bobbling, that causes an unwanted repeated tone.

Getting the best touch and tone out of a piano requires regulation of the key height, as well as many other adjustments. A piano goes out of regulation gradually, and a pianist may not notice lessened performance right away. It’s possible to keep the regulation close by touching up several major adjustments every year. If you decide to let the piano go ten or more years, it will need a full sixteen hour regulation. In either event, a piano will only reach its full potential and play its best when the regulation is fresh, and then maintained.

Symptoms of a piano in need of Regulation

  • Notes that will not repeat fast enough
  • Notes that ‘bobble’ or repeat unnecessarily
  • Uneven key response
  • Notes that do not sound fully
  • Key touch too shallow or deep


Every piano has its own voice, also referred to as tone quality. Many piano owners mistakenly assume if they don’t like the voice of their piano there’s nothing a technician can do about it. While a piano’s voice is the result of the piano’s design and construction, there is also a great deal of flexibility to a piano’s voice. The same piano can sound bright and ‘brassy,’ or more mellow and ‘dark.’ In fact, voicing changes as a piano is played. The shape, density, and mass of the hammers all contribute to the piano’s tone quality and tonal responsiveness. Regulation can also affect voicing. Communicating your voicing tastes to your technician takes time and cooperation, and yields a superior piano that more closely meets your artistic needs. Our technicians will work with you to achieve the best voicing for your piano and the room it’s in.

Symptoms of a Piano in Need of Voicing

  • Dull or thin tone quality
  • Harsh tone quality
  • Unappealing or ugly sound
  • Lack of power
  • Uneven tone from note to note
  • Piano is too loud
  • Overly bright, or brassy tone quality
  • Lack of tonal variety

Reasons for Changes in a Piano’s Pitch

String Elasticity

Strings stretch under normal tension. The piano is designed so the strings have just enough tension to stretch and deform them slightly. If string tension is incorrectly set too high, the strings may break. If tension is incorrectly set too low, the piano will have an unpleasant tone, as well as be unplayable with other instruments.

New piano strings will stretch so fast that a new or recently rebuilt piano will require three to four tunings in the first year. Older pianos can be more stable, but, often, if they have not been tuned regularly, they may have stabilized below concert pitch. In the case of both the new piano and the older, neglected piano, the piano will require a pitch adjustment from below pitch, known as a pitch raise, and fine tuning. A pitch raise is the most common form of pitch adjustment.

Weather changes cause strings and soundboard to expand and contract Due to the Washington, DC area’s seasonal changes, a piano that is behaving normally will drift, in general, about ten cents (or two beats) flat or sharp of A440. The longest steel strings, near the break between tenor and bass, will tend to drift twenty cents. This amount of pitch shift should not present tuning challenges.

Pitch will start to drift flat in the winter when it becomes necessary to run the heat in the daytime, and sharp when the heat is turned off entirely and or when the rainy season begins in the Washington, DC area (some years April; some years May). Tunings completed in January and July will be the most stable. A pitch adjustment to lower pitch is usually the result of excess humidity.

Felt hammers pound and stretch the strings. When the piano is played heavily, the repetition of hammers striking the strings will accelerate the normal settling process. The above causes of pitch drift are all normal events in the life of a healthy piano.

Structural shifts are serious problems such as a defective pin block or back beam separation. Shifts in the piano’s structure, including defective pin blocks, plate cracks, and back beam separations, are not normal. A piano that has experienced structural shifts needs to be carefully evaluated. There are usually several options to discuss with your technician when dealing with a damaged piano.


Climate Control

Everyone needs to stay warm in the cold weather. Unfortunately, that cozy fireplace could be wreaking havoc on your piano. While you may be aware that a piano requires a stable temperature, you may not know it’s even more essential to maintain an appropriate humidity level. Even mild changes from central heating can be hazardous.

In times of high humidity, wood swells and puts stress on the piano’s many glue joints, such as those that hold the hammers to the hammer shanks. As the wood dries, damage is visible as cracks and separations. These fluctuations also change all the fine adjustments your technician has made to your piano’s action.

If you’ve experienced sticking or lazy keys, a humidity change is often the culprit. While sticky keys are hard to ignore, you may be unaware of more serious humidity-related problems. In addition to damaging the piano’s glue joints, fluctuations in humidity can cause damage to your piano’s pin block, soundboard, and strings. Humidity changes also alter the string tension and cause the piano to go out of tune.

A good rule to remember is if it’s uncomfortable for you, it’s uncomfortable for your piano. The ideal climate for a piano is a temperature between 68° F and 76°, and the ideal relative humidity is 42%. In the mid-Atlantic area, if you’re keeping your piano’s environment within ± 10 of 42% you’re doing well. If you are unsure of your piano’s current environment, your PianoCraft Service technician can test it at your next service visit. We also encourage you to purchase your own thermometer-hygrometer to see how the environment changes across days, or even throughout the course of one day.

Controlling humidity can add years to the life of your piano. It’s important to keep a piano out of direct sunlight and away from direct exposure to air vents, at any time of year. A Dampp- Chaser Life Saver Climate Control system (with dehumidification and humidification) will help stabilize your piano year round. Some choose to combine a room humidifier and a Dampp- Chaser heater bar and humidistat (sometimes called a ‘partial’ system). It’s best to have the partial system installed in the winter months before April.
