Ancient Piano Age:
According to historical records, the earliest ancient piano was called Craveca, which was created between the 12th and 14th centuries. Gupianos can actually be divided into two types: one is plucked gupianos, and the other is percussion gupianos, which are also called harpsichords. In the Baroque period, the position of the clavichord was extremely important. In the bands and chamber music at that time, the players who played the clavichord played a leading role. In opera performance, it is also needed to accompany recitation, which continued until Mozart's time. Whether it is a plucked clavichord or a percussion clavichord, the sound produced is relatively weak, the strength cannot be changed, and it lacks expressiveness. These two kinds of pianos were gradually replaced by hammer pianos in the 18th century.
Modern piano era:
In 179, Italian piano manufacturer Christofi improved the harpsichord, successfully manufactured a mallet wrapped in leather on a wooden core, and invented the hammer-type piano with keyboard machinery, which laid the foundation for modern piano keyboard machinery. Because of this improvement, it makes up for the deficiency that the volume of the ancient piano can hardly be adjusted, so that when the piano is played, it can obtain the volume change from the random change of the tapping force on the keys, which can be divided into different grades according to the tapping force on the keys. This kind of piano is called harpsichord with strong and weak tones. Since then, due to the efforts of many pianists, in 1812, Eller of France once again improved the structure of the string striking machine, making it a compound vibration playing machine, further improving the performance of the piano. This further improved piano can quickly strike the strings repeatedly and play complex music. In 1825, some people tried to make a string frame made of cast iron, which enhanced the bearing capacity of the string frame to the huge tension caused by the tension of the strings, so that the strained strings would not relax because of the deformation of the string frame. This improvement has created good conditions for the stability of piano pitch and the improvement of its service life. After the continuous improvement and development in the later period, the piano has a cross arrangement of strings, which replaces the previous parallel arrangement of strings on a plane, thus solving the problem that the bass strings are too long to make the string codes and strings difficult to place, and opening up a new way to rationally use the vibration area of the soundboard and reduce the piano volume. Through continuous development, a mallet made of felt and wood core has appeared on the piano, replacing the mallet wrapped in leather. This kind of felt mallet is improved and used in piano production, which adds new expressive force to the piano playing effect. Modern piano has gradually become more perfect in the continuous development and improvement of nearly 3 years.
Maintenance and maintenance of piano:
Whether the piano is properly maintained not only affects the playing effect, but also relates to the service life of the piano. When maintaining the piano, we should pay attention to the following aspects:
* Moisture-proof
Most components of the piano are made of wood and iron, and their combination depends on screwing and gluing. When the piano made of steel
is wet, many parts will be inflexible, steel wire and metal parts will rust, wooden parts will be deformed, the bonded parts will be degummed, and when it is seriously wet, the quality of the whole piano will be reduced, even difficult to use. Therefore, it is very important to prevent the piano from being wet, especially in the south. If the house where the piano is kept is wet, it is best to make a small wooden platform, put the piano on the wooden platform, and scatter some quicklime under the platform. It would be better if you put some desiccant (such as silica gel) in the piano. The desiccant can be put in several small cloth bags, which can be taken out to dry or dry regularly in wet season and then put into the piano. Some people make a piano cover with flannel to protect the piano, and even wrap it up with several layers of plastic sheets. In this way, subjectively, it seems to protect the piano, but in fact, it is damaging the piano, and the piano is airtight. In fact, as long as it is covered with a layer of cloth, the rabbit can get dust in it. In case the piano enters the water, please ask someone who knows how to dry it carefully in time.
* Heat protection
The piano is afraid of the sun and the heating, otherwise the soundboard will crack, the wooden parts will be deformed and it will be easy to degum. Other parts are also easy to be damaged. Therefore, the piano should be placed in a ventilated, damp-proof place away from heating.
* Dust-proof
It is also important to keep the inside of the piano clean. In order to prevent dust from entering, it is best to cover the upper body of the piano with a piece of cloth, and then spread a soft cloth on the keyboard. After using the piano, you should cover it with your hands. To prevent dust and other sundries from falling into the keys of the piano.
* moth-proofing
Many parts in the piano are made of high-grade wool felt and woolen cloth, which are easily eaten by insects. To prevent moth-proofing, a bag of sanitary balls should be hung at both ends of the machine frame, and some sanitary balls should be scattered on both sides of the pedals.
* Anti-collision
The piano is collided, which will affect the appearance and loosen the internal parts. In severe cases, it will damage the internal parts, and even break the steel plate. When moving the piano, some people think that there are four wheels under it that can be pushed around with force. In fact, that is completely wrong. When pushing the whole piano hard, it will vibrate badly, not only the strings will be out of tune, but also the parts of the parts will be damaged. Therefore, when moving the piano, it is best to lift it, or push it gently to prevent violent vibration. If it is transported for a long distance, you must nail a wooden box and fix the piano in the wooden box. You can screw it to the support post on the back of the piano from the outside of the wooden box with large screws. A wooden strip should also be placed on the cover of the piano. The wooden strip should be fixed on the wooden box, and the foot of the piano should also be fixed with wood. In short, to make the piano immovable in the wooden box, use sponge, PVC foam or shredded paper to cushion the place where the piano is in contact with the packing box. Rub the paint with a rabbit.
* Repair it in time
If the piano is faulty, it should be repaired in time. It is easy to damage the internal parts when playing the piano with a disease, and it should be overhauled at least once a year. It would be better if it is checked and tuned every three or two months, because the tension of the strings will change with the change of seasonal heat and cold, which will directly affect the intonation. Regular maintenance and tuning can find the problems in time and eliminate the faults. Make the piano always in the best working condition. In addition, don't put ornaments such as photo frames and vases on the piano, which will affect the sound or damage the surface of the piano when the rabbit plays. In short, as long as the piano is carefully maintained and taken precautions, the service life of a piano will be very long, and it can accompany a person for life and even serve several generations.
