Buying a piano is an exciting thing for any music lover who studies the Piano.
However, the Piano is a complex musical instrument with strict requirements on the environment; many people are often due to the lack of piano knowledge and lead to serious consequences.
Why is the Piano out of tune?
The tuned Piano will be under a lot of tension. (the average medium-sized Piano has about 230 strings, each with a tension of about 165 pounds, and all of the strings have the equivalent tension of 18 tons!)
As pianos experience climate change, wood expands, and contracts. As this happens, the tension on the piano string changes (and hence the pitch).
Low Humidity, low pitch
The Piano’s soundboard shrinks during periods of low Humidity, and the strings have less tension, so the pitch sounds lower.
High Humidity, high pitch
At high Humidity, the Piano’s soundboard expands. There’s more tension on the strings, so the pitch sounds higher.
Humidity fluctuations can not only throw your Piano out of whack, but they can also wreak havoc on its structural integrity.
Minor damage due to fluctuations in Humidity includes “stick key” that reflects slowness and loosening of screws.
More serious damage that can occur may include problems such as corrosion of the strings, Glue Joint Failure that causes loud buzzing, Code Bridge cracks, cracked soundboard, and loose tuning pins.
So piano maintenance should try to keep the piano temperature and humidity balance.
MOISTURE PROOF:
In general, please be sure to close all the windows of the piano room in cloudy or rainy weather. Be Sure to close the LID after each play.
In a dark and humid environment, the cover can be put on to prevent water from the air. However, the cover should be dried in good weather. The precision of the wire-striking mechanism made of wool felt, leather, and wood is very high, the permissible margin of error is limited to 1 / 100mm.
These components are very sensitive to changes in Humidity, and Humidity too high will lead to slow action, Piano dull, metal rust, and key failure, etc.
The optimum temperature is 20-25 °C, and the Relative Humidity is about 40-70%. When the relative humidity is more than 75%, a moisture discharger and a moisture absorbent can be installed in the Piano.
ANTI-DRYNESS:
1. Winter use heating, air conditioning, furnace room should pay special attention not to blow the hot air directly to the Piano, should try to stay away from the heat source.
Because some rooms in the winter, its relative Humidity will fall below 20%, on the piano protection is very adverse.
2. Use A humidifier.
3. You can put a pitcher on the Piano.
4. Keep broadleaf plants in your room.
5. Avoid drastic temperature changes and have adequate ventilation.
If it is very cold outside to move the piano into the house, should open the doors and windows in advance, let the temperature in the house after the Piano into the house, gradually warming up.
The optimum temperature for a piano should be about 22 degrees.
