INTERESTING PIANO FACTS

·pianos are percussion instruments

·the average piano has aproximately 230 strings

·pianos weigh from a few hundred pounds to 2600 pounds (Rubenstein Piano)

·a Steinway concert grand piano is 9’ long

·a 12’ 2” piano built by Rubenstein Pianos is the largest in the world

·a standard piano has 88 keys

·the Rubestein piano has 97 keys

·some pianos built in the early 1900’s were essentially grand pianos turned up vertically- these were called giraffe pianos and could stand 7’ high

·the amount of downbearing in a piano (amount of downward pressure on the soundboard) can be as much as 1000lbs

·combined string tension in a piano is around 20 tons

·a single piano contains as many as 12,000 parts




HOW OFTEN SHOULD MY PIANO BE TUNED?

The truth of the matter is, when it starts to “sound bad”, but because “sounding bad” is subjective, we recommend a proper tuning schedule for your piano.  A piano that sounds good to an amateur may not be up to par for the concert pianist.  For this reason we recommend a tuning schedule of twice a year for pianos in light use situations such as homes and up to four times a year for pianos in higher use situations such as a church sanctuary’s piano.  For pianos in very high use settings and demanding applications such as recording studios and concerts, tuning as many as a few times a week is in order.  If you have questions regarding a particular situation contact us and we can advise you on a proper tuning schedule.   As a reference, when working for Berklee College of music in Boston with over 200 pianos, the pianos would get tuned a minimum of once a month (most were tuned more often).  These pianos were played 8-10 hours per day as practice pianos.



WHAT CAUSES MY PIANO TO GO OUT OF TUNE?

Changes in humidity, piano strings stretching, moving...  There are many factors, but keeping your piano in a constant, controlled environment is the most important.  A relative humidity of 40-50% and a temperature in the 70’s is best.  As the temperature changes so does relative humidity.   Keeping your piano at 85° and 40-50% humidity is not the same as keeping your piano at 75° and 40-50% humidity.  Keeping consistent temperature and humidity is very important.   It’s easy to go on a summer vacation, turn the air conditioning from 75° to 85° and forget about the piano. 



WHAT IS A HUMIDITY CONTROL SYSTEM AND DO I NEED ONE?

In a grand piano the humidity control system is hidden up underneath the soundboard.  In a vertical piano the humidity control system is contained inside the bottom of the piano.   The system is completely automatic and the owner only needs to add water when the yellow light blinks.  These systems are simple to use, cost only pennies a day to operate and extend a piano’s life.  These systems are installed by a piano technician and provide trouble free service.  We are a Certified Installer of the Piano Life Saver systems by Dampp Chaser and we install these systems exclusively.  Piano Life Saver systems carry a 5 year limited warranty and are handmade in the USA.  Visit Piano Life Saver for more information.


The humidity control system consists of one or more Dehumidifier rods to lower humidity, one or more Humidifiers to add humidity, and a Humidistat which is a humidity sensing/control unit.  The Humidistat is calibrated to create a separate environment (keeping the piano at 45% relative humidity) within the piano through a cycling action. This produces a range of humidity which provides a stable moisture content in the wooden parts.  This constant cycling action stabilizes pitch and protects the piano from deterioration.


The most important part of good piano maintenance is keeping the humidity as constant as possible.  Because tuning stability and physical deterioration are the obvious results of continued humidity extremes, the installation of the humidity control system is a convenient method to ensure the piano is protected from the damaging effects of broad swings in the humidity. 


FLORIDA RESIDENTS: We personally recommend a humidity control system for every piano.  Here in Florida sometimes it is possible to use a dehumidification only system without the humidification portion.  This dehumidification system is still automatic.  The drawback is that in the winter when humidity is low the dehumidification system cannot add humidity.  In Florida, if keeping the initial system cost low is a priority, then choose just the dehumidification system.  Although the dehumidification only system is not as beneficial as a complete humidity control system, your piano will still benefit.  Please contact us for pricing on the dehumidification only systems.


Piano manufacturers that recommend humidity control systems:

Baldwin, Bechstein, Bluthner, Bosendorfer, Fazioli, Kawai, Mason & Hamlin, Pearl River Pianos, Petrof, Sauter, Schimmel, Steinway
