The sound of pulling the erhu is made by the vibration of the strings, right?

It should be the bow rubbing the strings to cause the barrel to vibrate.

The erhu uses kneading strings to pull out two distinct identical notes with a bow.

There are many types of kneading strings, all the methods that use the continuous change of string length or tension to produce sound waves can be called kneading strings, among which tumbling is the most basic kneading technique, which is to swing up and down with the palm of the hand, drive the first joint of the fingers to bend and stretch the movement, so that the fingertips roll evenly on the phoneme, to change the length of the string to produce sound waves.

Tumbling is composed of two action processes, the first process is: the palm of the hand is raised, so that the first joint of the finger is straightened, and the finger surface touches the string, which at this time produces a sound slightly lower than the baseline of the pitch; The second process is to swing the palm of the hand, so that the first joint of the finger is bent, and the touch point is rolled to the fingertip, which produces a note slightly higher than the baseline of the pitch.

The cycle repeats itself, with the fingers rolling evenly on the phoneme, resulting in a kneading sound that fluctuates up and down around the pitch baseline. When tumbling, the active point of the action should be placed on the back of the hand, and the palm of the hand should only move up and down, not inside and out. The wrist is an "axis" of movement, so the wrist must not be stiff.

The erhu uses a bow to pull out two distinct and identical sounds

1. Broken bow. After pulling the first 5 bows, pause slightly, keep the direction and strength of the bow unchanged, and then pull the second 5. The pause time is determined according to the tempo and time value of the piece;

2. Change strings. After pulling the outer string empty string 5, keep the direction and strength of the bow unchanged, press the 5 of the inner string with four fingers, but the bow hair is changed to the inner string to play.

3. Liantun bow. Keep the direction and strength of the bow unchanged, and play two echo notes elastically. In the song "Festival" (2 6 strings), 16 notes are required to be played with a bow.

4. Throw a bow. The bow is lifted upwards and smashed against the barrel, taking advantage of the elasticity of the bow shaft, and the bow hairs are two or three 5 on the string.

Pulling the erhu is a combination of finger and bow techniques.

If you don't press the strings, the bow pulls the inner empty string for 1 tone.

Press the index finger on the string, and pull the inner string of the bow for 2 tones.

The middle finger is pressed on the string, and the bow pulls the inner string for 3 notes.

The ring finger is pressed on the strings, and the bow pulls the inner strings for 4 notes.

If you don't press the strings, the bow pulls the hollow strings for 5 tones.

The index finger presses the string, and the bow pulls the outer string for 6 notes.

The middle finger is pressed on the string, and the bow pulls the outer string for 7 tones.

The ring finger is pressed on the string, and the bow pulls the outer string for 1 (high) note.

In the case of two identical notes, it means that only one note is played but it is the value of two notes, and if it is a repeater (two notes and more than two notes), it is pulled with one bow.

The erhu belongs to the 12 equal temperament instruments. All tones can be pulled. Seven tones that are commonly used. c, d, e, f, g, a, b. The strings are one of the articulatory bodies of the qin and one of the sound sources of the erhu. The quality of its quality directly affects the pronunciation effect.

Tell me earlier. The arc above this is called a ligato line, that is, the sound below the line is pulled out by a bow, and the bow cannot be changed. Like this time value is the time value of one and a half beats, although it is two 3s, but when pulled out, it is a bow, here, the arc is equivalent to the delay line, that is, the tone of the previous 3 is extended by one beat.

For example, if the two notes below the arc are 32, that is, two notes are pulled with a bow. That's it.

There is a deliberate pause in between.

The two notes use different forces, and the force can be added when the second note is pulled.

Add ornamentation to one of the notes to distinguish.

It's the finger that keeps the sound of 3, and the bow is stretched enough to be worth the time. For example, in the second beat, pull a long note 3 in the second beat

There are many ways to achieve two notes of the same pitch with a bow without changing the direction of the bow, and the specific method should be determined according to the expression needs of the piece. Let's take 1 5 5 of the 5 string as an example to illustrate:

1. Broken bow. After pulling the first 5 bows, pause slightly, keep the direction and strength of the bow unchanged, and then pull the second 5. The pause time is determined according to the tempo and time value of the piece;

2. Change strings. After pulling the outer string empty string 5, keep the direction and strength of the bow unchanged, press the 5 of the inner string with four fingers, but change the bow hair to the inner string to play.

3. Liantun bow. Keep the direction and strength of the bow unchanged, and play two notes elastically. In the song "Festival" (2 6 strings), 16 notes are required to be played with a bow.

4. Throw a bow. The bow is lifted upwards and smashed towards the barrel, taking advantage of the elasticity of the bow shaft, and the bow hairs are two or three 5 on the strings.

I don't understand what you mean. To put it bluntly. Do you mean to use the erhu to play the double tone? Or is it a bow that pulls the first half of the do, and the second half of the treble do? Or something else?

It's too vague, do you mean a false sound?

Summary. Hello dear! When you move the erhu strings from the bottom to the top with the same force, the sound is from high to low.

We use the same force to move from top to bottom, and the sound produced is from high to low, and this is because the shorter the string, the faster the vibration, and the higher the sound.

It's from high to low or low to high.

Hello dear! When you move the erhu strings from the bottom to the top with the same force, the sound is from high to low, and when you move the erhu strings from the bottom to the top, the sound is from low to high. We use the same force to move the sorghum from top to bottom, and the sound is from high to low, because the shorter the string, the faster the vibration, and the higher the sound.

Erhu began in the Tang Dynasty and is called "Xiqin" and has a history of more than 1,000 years. It is a traditional Chinese stringed instrument. Erhu, that is, the two-stringed huqin, also known as "Nanhu", "Huzi", erhu is one of the bowed string instruments (rubbing string instruments) of the Chinese national musical instrument artists imitating the main sail in the Jin clan.

Famous erhu songs include "Erquan Reflecting the Moon", "Preparing the Sedan Chair for the Good Night", "Listening to the Song", "Horse Racing", "The Grapes Are Ripe" and so on.

The erhu relies on the vibration of the strings to produce sound, and its quality directly affects the pronunciation effect. There are two types of strings: one is metallic and the other is silk.

The erhu is a traditional Chinese Huikuo stringed instrument with two strings, which began in the Tang Dynasty and has a history of more than 1,000 years.

The erhu includes the body (including the stem, barrel, holder, membrane, and sound window), the string system (including the strings, pins, jacks, saddles, and sound pads), and the bow (including the bow fish, bow rod, and bow hair). Luthiers usually make erhu from wood, such as mahogany, rosewood, ebony, etc. One end of the barrel is covered with snake skin, which is the unique sound of the erhu, and some high-end erhu uses python skin.

Famous erhu songs include "Erquan Reflecting the Moon", "Good Night", "Listening to Song" and so on.

Hello dear, here is the query for you that there will be no sound of shaking sound when the erhu inner string is hollow and the bow is drawn. 1.If there is a jitter sound when the bow is drawn, it may be due to the uneven tightening of the loose sail of the string, especially when the bow is drawn, there may be a large gap between the tightness of the left and right strings, and the tightness of the right side is higher than that of the left side, resulting in an inconsistent sound when the left and right strings pass through the bow.

2.In order to solve this problem, you can consider adjusting the string tightness on both sides when drawing the bow, and try to keep the gap as close as possible in the range of the smallest slag pie to avoid jitter sound. 3.

In addition, in order to maintain the balance of the tightness of the strings, you can also tighten the strings first when changing the strings, and you also need to pay attention to the tightness of the strings when pulling the bow, and adjust the tightness difference between the left and right strings not too much, so as to ensure the auditory effect of the erhu.

These two vibrating objects are not the same. The body of the saxophone is a resonant cavity because the column of air in it vibrates to produce sound. The erhu is rubbed against the strings by the tail of the bow, and the vibration of the strings is transmitted to the python skin through the horse, and the python skin vibrates through the barrel to amplify the sound.

The saxophone was invented by Antoine-Joseph Sax (1814-1894) in 1840. Adolf was an avid instrument maker and specialised in clarinet and flute playing. His original idea was to design a low-level instrument for the orchestra that would be more flexible than the Ophicleide and could be adapted to outdoor performances.

He combined and improved the mouthpiece of the bass clarinet and the body of the Opclyde horn, naming the new instrument after himself.
