How to tune pianos?

Internet is full of incorrect advice on how to tune a piano. It is generally recommended to use an electronic tuner, such as those used for guitars, to tune each note to an absolute pitch. Piano tuners generally use electronic tuners, but these are not the chromatic guitar tuners out $ 20. These are sophisticated devices that measure the disharmony and provide a uniformly heated pitch (and leaving more than 1000 dollars!). In addition, many of these items listed on the internet make it seem an easy process to learn, which is not true. This type of advice is not good, for two main reasons:

1) When tuning a piano is intended that this has an equally tempered tuning, rather than having absolute tones. Just a note, usually La-440 is tuned to have an absolute pitch. After this note is ready, the rest of the notes are tuned based on it. Take all the notes with a tone that assumes all the strings vibrate according to the theoretical mathematicians, but this is not true. For the piano strings to vibrate in accordance with these principles of mathematics, the instrument would be enormous. Because it is not practical to have a big instrument, the piano strings are shrinking and use of different thicknesses to simulate these theoretical properties.

This, however, causes what is known as disharmony (For more information visit their website disharmony in Wikipedia). Then all the pianos have disharmony due to the properties of the tension of the strings, and thickness. In addition, each piano has its own degree of disharmony. The larger pianos will have a lesser degree, while the smallest one greater. This makes the tuning process is a specific task for each instrument. To take account of disharmony, the notes of a piano does not tone down its “theoretical” or absolute, but stretched a bit in the entire keyboard range. Otherwise, then the harmonic intervals with the modulation of a note to another, it would sound horrible. As you can imagine, this requires a trained musical hatred, which is acquired after many hours of practice.

2) Another difficulty with the process of tuning a piano is the enormous amount of work involved. A piano has more than two hundred pins, which makes it very different tune four to six strings of a violin or guitar. It is rare that all the strings need to be adjusted, but anyway, unless your really good ear for music this coming, it is very difficult to determine which strings need to be adjusted and what not (and also, as previously explained, a tuner e will not help in this case).

To set the tone should be a great skill in using the tuning key, and probably if one is learning to possess this ability, breaking a string ends in the process. If this happens, buy a rope from a store that sell items piano. Change the string is not an easy task since one must open the piano and insert the rope behind the other strings and around the pins without bending. Finally, to tune a piano on your own, you have to buy a tuning key, a strip of felt and rubber wedges, without these tools you can not tune a piano properly.

These issues are raised, not to discourage beginners to learn to tune a piano, but to alert the experimenter occasional difficulties and dangers of this task. If a person really wants to learn how to tune a piano, you can do, but as long as you keep in mind how difficult it is. You are encouraged to consider several pitch books to prepare well.
