1. How to tune the piano
1. Determine the standard pitch
Use a tuning fork with a group of small characters to tune it, and calibrate the a in the small group of characters. But it is not a simple matter to tune this note accurately. In addition to hearing accurately, accurate technique is equally important
This requires focusing on practicing the ability of fine-tuning, sensitively feeling the rotation of the pegs, and listening accurately. Make a beat sound.
2. Temperament
First, use the tuned a note as the benchmark to divide the temperament of "four up, four down, five". The temperament of the piano is twelve equal temperament. The 24 cents that cause sound disharmony are evenly distributed to every two adjacent notes, so the beat frequency of a perfect fourth and a perfect fifth is about 1 beat/second, that is, every two adjacent notes. Add two cents to the adjacent note.
When it reaches the end, start using the "three-sixth test method" for testing, that is, the beats of a major degree and a major sixth are the same. Each note that is tuned is based on the previous note
As long as there is an error in one note, all the following notes will be incorrect. When the last perfect fifth cannot match, , it is necessary to perform reverse tuning to find the error
error point.
3. Tuning of unison and octave
To ensure the speed and accuracy in the tuning of unison and octave, the tuning of unison and octave The key is to tune the strings that emit the same note to the same frequency without any beat notes. In this way, all 88 notes of the piano can be tuned.
2. Piano Tuning Skills
If we have professional music knowledge and training, we can use our ears, that is, hearing to listen to the tone of the piano and tune it. 6 shall prevail
Adjust in the following order. Every time you adjust, you need to listen carefully to the level of the tone.
In addition to listening with your ears, you also need to know the structure of the piano, which is divided into three areas: treble area, alto area, and bass area. These three areas are distinguished by the number of strings, and the treble area is one

There are three strings corresponding to each note, two in the alto range and one in the bass range. Generally, the tuner will tune one string of the same note in the middle and high range first, and pay attention to using your ears to listen to the high and low notes and the timbre.
If we do not have the skills in this area, we can find professionals to adjust it. We must not adjust the sound of the piano randomly by ourselves. Another way is to buy a regulator
to replace it ourselves. You need to use your ears to listen to the sound of the piano and make adjustments, but the editor recommends that it is better to have a professional, because piano tuning requires a certain amount of technology and experience
3. Piano tuning knowledge
1. There are many tools required for piano tuning, which generally include children’s music instruments (including stopper notes, ascending pitch notes, and let notes). Tone belt, small treble clip, treble | sound stick,
Metal handle treble mute pitch and chain-type tuning pitch and other instruments), tuning tools (mainly including tuning forks, electronic tuning forks and tuning forks) Accuracy instrument and other equipment), tuning tools (tuning wrench
hand) and auxiliary tools (socket loading and unloading wrench, screwdriver, reverse stopper adjustment wrench).
2. When tuning upright pianos, pay attention to the position and angle of the board. It is best to place the tuning wrench within 45° above the tuning axis, and it is strictly prohibited
Some tuning experts mention that tuning with the left hand is to reduce damage to the peg board and cause premature peg loosening, thereby reducing the intonation and service life of the piano.

Life is extended.
3. It is not advisable to tune a newly purchased piano in a hurry. Because new pianos often undergo major changes in new environments, and changes take time. After rapid tuning, the pitch is not easy to maintain
and the tuning cost is wasted. It is generally best to leave it for half a month to three months before adjusting.
