What is the tuning of the piano?

The piano may look like a solid tool that does not require tuning, but it is not. In fact, it is recommended that the new piano be tuned three or four times during the first year and then twice a year, whether or not it is played. But how does the piano get out of the melody in the first place and why does such a secret surround the piano?

The answer to both questions is in the construction of the piano. Pianos are made of materials that age, breathe and change shape with time and weather conditions. Wood, iron, leather, felting and steel get into the piano. Each piano has thousands of complex moving parts and a complex system of 250 or more steel chains with high strength attracted through the iron harp, which holds 40 tonnes of string tension! Each chain is wound around a tuning pin, which is inserted into the block of the wooden pin. The pins must fit very cozy to maintain tension. When the piano is tuning, these pins must be carefully turned on one Ange of Every Commpant SinGC. This is done with tuning with a hammer and requires a large amount of carefully applied force.

But the piano tuning is more than just turning the tuning pin. When you suppress a single key on the piano, the hammer hits a set of two chains for lower octaves and three strings for higher octaves. This set of chains is tuned to the same playground to create a single note. If one of the chains in the set is flat or sharp, the only note can be tuned by itself! When the piano is tuning, a single chain inside the set sounds individually and rubber wedges are used to stop the vibration of other chains. Once this string is tuned, the second string can vibrate along with the first and is tuned to it and so on and so on. It is an extremely slow, methodological process that requires expertise, good ear and a lot of patience.

The piano chains last about 20 years before they were to be replaced. This is nAid expenditure, so many people just live with old strings. Piano tuning then becomes even more difficult, because the older the strings get around the 20 -year -old brand, the more prone they become. Peg must be very carefully turned and the string has allowed to "rest" between small adjustments. However, there will be a time when tuning is no longer safe to carry out the risk of breaking the chain.

In the United States, piano tuning generally costs about $ 120 and is considered a regular need to keep the piano in good playing throughout your life. Do-it-yourself piano tuning is not recommended, although books and guides are available on the topic for those interested.
