Humidity Control for your Piano

 Many people are not aware that humidity can have a profound effect on the tuning and performance of your piano. Humidity is a measure of how much water vapor is in the air, relative to the maximum amount of water vapor it can hold (that’s why it’s called relative humidity!).  Your piano is subject to wide swings in humidity. This is particularly true in the Hudson Valley, where the majority of our clients live. In the summer, humidity levels can go as high as 100%, while in the winter, your heating system can drop the relative humidity in your home into the single digits.

What does this mean for your piano? When the humidity is high, the soundboard and bridges absorb moisture and swell, increasing the tension of the strings and forcing the piano sharp. When the humidity is low, the opposite happens - the soundboard and bridges release moisture and shrink, reducing the downward pressure of the strings and forcing the piano flat. This is why almost all piano manufacturers - and your piano technician - recommend that your piano is tuned twice a year. In addition to forcing your piano out of tune, increased humidity affects the action parts, swelling the wood and increasing friction, which can make your action respond sluggishly (a major cause of “sticking” keys).

How can you mitigate the effects of humidity on your piano? There are several options. The absolute best solution is to have your whole house humidity controlled. This involves either attaching a humidifier to your HVAC system or installing a separate humidifier/dehumidifier system in your home. While this is the best solution, it can be very expensive to install and maintain, and is usually cost prohibitive.

The next, and we think best, solution is to install a humidity control system directly in your piano. The Dampp Chaser company, makers of the Piano Life Saver system, is the only company making these systems. Over the past 74 years they have perfected their system and adapted it to work in all pianos. This system maintains the relative humidity of your piano within a few percent of the ideal level of 45% Relative Humidity. A humidistat regulates the humidity, similar to the way your thermostat regulates temperature. If the humidity is high, the humidistat activates low power dehumidifier bars to dry out the piano. If the humidity is low, the humidistat activates a humidifier - a gentle version of that which you might put in a room. Periodically, you must fill the humidifier tank with water. This can be disconcerting the first few times, pouring water into a tube that disappears into your piano!

In grand pianos, the system is installed underneath the piano, in direct proximity to the soundboard. An under cover will aid in the effectiveness of these systems. A dehumidifier bar is installed at either end of the underside of the piano, and a humidifier tank is located in the approximate middle.

In vertical pianos, the system is installed in the lower half of the piano, inside the knee board. There is one dehumidifier bar which runs the width of the piano, and the humidifier tank generally rests on the bottom board. A watering tube extends from the top of the knee board to underneath the key bed.

Routine care of the system involves replenishing the water for the humidifier tank, when prompted to do so by a discreet light panel mounted underneath the key bed. The system will be serviced by your technician when they comes to tune your piano; this involves replacing the humidifier pads and testing the system. The system comes with a five year warranty, which New York Piano Works will double to 10 years provided we continue to service the system.

Other than routine care by a qualified technician, a Piano Life Saver system is the best investment you can make towards the quality and consistency of your piano. Click HERE or contact us for more information! For more information click here: Piano Humidity Control

Basics of Piano Care

FIRST POST! Thanks for checking out this blog page. We will be adding content every week or so, as long as we keep coming up with interesting and informative things to say.

I’d like to start by talking about basic piano care… The aspect of piano care that everyone is familiar with is tuning. Pianos go out of tune due to changes in humidity, which swells and shrinks the wood of the soundboard, bridges, and action parts. This happens regardless of how much or how little the piano is played. We STRONGLY recommend having your piano tuned twice a year. This is in line with all manufacturer’s recommendations. If you put it in terms of car maintenance (the other big, complicated machine in your life), tunings are the oil changes of piano care. It’s important to note that your piano may be out of tune and still sound relatively ok, but not be at the correct pitch. More on this in a future post. Is your piano out of tune? Find out how to determine this here.

A piano is a very complex instrument, with up to 10,000 parts - many of which move and are subject to wear over time. This causes the piano to function at a sub-optimal level, lessening your enjoyment and making playing and learning more difficult. The good news is this is a relatively easy condition to combat. Every 3 years or so, the action should be serviced. To do this, we remove the action, clean it with compressed air, lubricate all action centers, and tighten all screws (over 200 in uprights!). This serves three purposes: it makes the piano play better, avoids problems due to contaminant buildup, and allows for the detection of small issues before they become big ones. If it were a car, this would be the inspection and basic tune up.

As the piano ages, the parts deteriorate. Felt gets compressed, screws loosen, and gravity acts on the hammers. The result is poor performance - lack of dynamic range, the inability to play softly, and unevenness of touch. The solution to this is regulation. Regulation is the adjusting of numerous measurements and tolerances for each note, bringing the piano back to a level of playability it enjoyed when leaving the factory (or better). This takes several hours, but it is a normal and necessary part of caring for your instrument. In car terms, it’s like having the transmission serviced, and alignment done, and a thorough tune up - like a 50,000 mile service. This should be done every 5 years or so, but can also be done piecemeal at your six month appointments to spread out the expense. Vertical Regulation is explained in greater detail here, and Grand Regulation can be found here.
