Pedals, tuning pegs, piano, damper, piano tube, soundboard and keys.

1. Pedal: refers to the pedal under the piano that is stepped on by the foot. It is the most important accessory of the piano besides the keyboard. It was invented in 1711 by Italian musical instrument maker Cristofori when he was renovating the piano.

2. Tuning nails: These are nail-shaped bolts that can be twisted and rotated with a special wrench. Its turning machine is made of special high-carbon steel with a lock, so the strings can be firmly wound on the pegs, so that the intonation can be maintained and stabilized for a long time under the high-strength tension of the strings.

3. Qin: It is covered with high-quality felt or flannel. Since this "skin" is mostly made of wool, it is also called a wool mallet. It is connected to the keys. When the keys are pressed, the hammers will hit the strings and the vibration of the strings will make the piano sound. Therefore, its function is to strike the strings that are tightly held by the tuning pins.

4. Damper: The damper is in close contact with the strings and is used to prevent the vibration of the strings. For example, when a key on a piano is pressed, the hammer inside the piano will hit the strings made of copper, and the sound will be produced by the vibration of the strings.

5. Piano bladder: The piano bladder connects the keys and hammers and is the soul and most important accessory of the entire piano.

6. Soundboard: The soundboard is a large metal steel plate located at the back of the piano. It is connected to the tuning nails and is close to the strings. When the strings are caused to vibrate and make sounds, the sound is heard. The soundboard will produce a double resonance of the sound, that is, the sound will be reflected and amplified through the soundboard.

7. Keys: The entire keys are composed of black keys and white keys.

Extended information

The origin of the piano:

The world's first piano was made in Florence around 1710 by the Italian Cristofori. It's called "Weakness and Strength." Later, almost all languages ??called piano Piano, which is the abbreviation of Piano e forte. Piano is called piano in Chinese, which is a Chinese name.

Just from the fact that the original name of the piano is "weak and strong", it has been explained: the player can play weak, strong, diminuendo, crescendo, sudden weak, sudden strong and other intensity changes and contrasts at will , this is the fundamental difference between the pronunciation principle of the piano and the fortepiano.

This difference is of great significance to the development of piano performance art and the promotion of piano music creation. This has been verified by the subsequent history of piano music. Christopher's great contribution lies in this.

Everything is difficult at the beginning. Although the piano he made is still very different from the common grand pianos and upright pianos we have today, after all, Piano was born in the hands of Christopherori. In the following hundreds of years, countless skilled craftsmen from various countries continued to improve it in terms of shape, structure, materials, range, timbre, volume, etc., before it became what it is today.
