The five representative musical instruments of Gong Shangjiao and Zheng Yu that most highlight each of them are:

Gong----drum.

Shang----metal instruments such as gongs, bells, or cymbals.

Horn----bamboo and wooden musical instruments, such as flute, bird song and other sounds.

Zheng----erhu, morinouqin and other string instruments.

Yu----guqin, guzheng.

Reason: It can be distinguished according to the timbre characteristics of the instrument. When you hear the drum sound, your heart will feel like it is building and moving with the drum beat. It is believed that it should belong to earth, the son can make the mother solid, and the sound of the drum will make the heart of the mother of earth solid and move. In traditional music, drums are often the prelude to music. And when attacking in war, the war drums are beaten.

Turtle controls water. Water belongs to the kidneys among the five elements and governs fear. Therefore, drums can reduce the soldiers' fear of battle and encourage rustic spirit. And "one vigorous effort, then decline, and three times exhaustion." also illustrates this point from the side. Therefore, the sound of drums should be regarded as the palace, and after the enemy retreats, in order to prevent one's own troops from blindly pursuing the enemy's ambush, the troops are retracted with the sound of gold. Gold is for convergence, and gold should be metal instruments such as gongs, bells, or cymbals. Should be business.

The horns should be made of bamboo and wood instruments, such as flutes, birdsong and other sounds. The tone is high and gentle. The Yang Qi rises in the morning. When you hear the birdsong, you will feel relaxed. You will have the same feeling when you hear the sound of the bamboo flute. When you hear the erhu, morinouqin and other string instruments, or when you hear the music of the yu, reed, and xiao, you will feel a distant and pleasant feeling, which can alleviate sadness and sorrow. It is classified as Zheng, which belongs to fire.

The feather should be the sound of running water or musical instruments such as guqin and guzheng. It can make people calm and can resist the feeling of slowness of joy and unfocused mind.

Gong, Shang, Jiao, Zheng, Yu" are the names of five different tones in the Chinese pentatonic scale, similar to 1, 2, 3, 5, and 6 in the current simplified musical notation. That is, Gong is equal to 1 ( Do), the quotient is equal to 2 (Re), the angle is equal to 3 (Mi), the levy is equal to 5 (Sol), and the feather is equal to 6 (La)

The earliest name of "Gong Shang Jiao Zheng Yu" is found in. During the Spring and Autumn Period, more than 2,600 years ago, in "Guanzi·Diyuanpian", there is a scientific method of using mathematical operations to obtain the five tones of "Gong, Shang, Jiao, Zheng, and Yu". This is the famous "Gong, Shang, Jiao, Zheng, Yu" in the history of Chinese music. "Three-point profit and loss method".

Basic knowledge of Guqin:

1. Music

In the rich and colorful music The world is full of all kinds of sounds. Some of them sound delicate, some sound rough, some sound soft, and some sound deep... It can be said that music is endless. An art of sound.

According to the rules of sound production, we can divide sounds into two categories: one is called music, and the other is called noise. Music has a fixed pitch and is harmonious. It is also pleasant to listen to. The sounds played by instruments such as piano, electronic keyboard, violin, and erhu are all musical sounds. The music world is mainly composed of musical sounds.

2. Sound names.

In order to name the sounds used in music, people use seven English letters. The arrangement of these seven letters starts from C and is called CDEFGAB. When singing. , we use do, re, mi, fa, sol, la, and si to sing the sounds on the music score. This is called roll call. The note names and roll call are both related and have different uses. Each is used in different ways. Please pay more attention when using it.

There is a specific mode in Chinese folk music, that is, the five tones: Gong, Shang, Jiao, Zheng, and Yu.

The seven tone names of CDEFGAB are used in a cycle. These sounds with seven tone names are the basic tone levels.

4. Semitones and whole tones

The smallest pitch distance between sounds is called a semitone, and two semitones form a whole tone. In the simplified notation, between 7 and 1, there is a semitone between 3 and 4.

Fifth. , notes

The symbols that represent the length of the sound in the music score are called notes, which are represented by 1, 2, 3, 4, 5, 6, and 7 in the musical notation.

Usually in the music score. Common notes are: whole notes, such as 5-, quarter notes, such as 5, and sixteenth notes. The length relationship between them is just like their names: whole note = 2 half notes = 4 quarter notes = 8 eighth notes = 16 sixteenth notes

6. Rest< /p>

The sound in the music does not stop all the time. Sometimes there is a break in the middle, and there is a silent time. At this time, another type of symbol - rest is used to represent it. The name of the rest is similar to the name of the note, and is represented by 0 in the musical notation. A full rest is as long as a whole note. A half rest is equal in length to a half note, etc.

7. Dotted Notes

Some notes need to be extended for a certain period of time. When notating, just put a small dot on the right side of the note. This small dot is called Attached. This note is also called a dotted note. A dot increases the note's duration by half the original value. Commonly used dotted notes include: dotted quarter note, dotted eighth note, etc.

8. Dotted Rest

If you know what a dotted rest is, you will also know what a dotted rest is. A dotted rest also increases the duration by half of the original rest. .

9. Tie-tie extension

To extend the time of a certain note, in addition to using dots, two other methods are commonly used. One method is to use a tie line to connect several notes of the same pitch together. When playing, these notes add up to play one note. Such as: 5---∣5---.

Another method is to add a extension above the note. The continuum looks like an eye, which means you can freely extend the time of the note as needed. The extension sign can also be used on rests.
