Use a fixed roll call method

1, the inner chord of erhu is d 1, the outer chord is a 1, and the two chords are separated by a pure fifth degree. So if you don't change the pitch of the empty string, no matter what tune you want to play, the pitch of the empty string will only be these two sounds, namely d 1 and a 1. In addition, in the first sound roll call method, d 1 and a 1 can be placed in any key, and the roll call varies according to the key, such as: the tonic and subordinate sounds in D major, singing do and sol；; Mezzo-soprano and tonic in B flat major, singing Mi He. Erhu generally uses the inner and outer chords marked at the front end of the spectrum to represent the calculation results. Erhu should also know that these results are calculated according to this principle and are not marked.

2. In each key, the empty and chord sounds of the first key of erhu are the inner chord on the left and the outer chord on the right, even though it is a key that erhu rarely touches. The purpose of doing this is just to show that as long as it is within the range of erhu, any sound that is turned out can be pulled out.

C:(2，6)； D:( 1，5)； E:(b7，4)； F/#E: (bass 6,3); G: (bass 5,2); Answer: (4,1); B:(b3，B7)； #C/bD:(# 1/b2，# 5/B6)； #D/bE:(7，# 4)； #F/bG: (bass b6/ bass #5, B3/# 2); #G/bA: (Beth b5/ Beth #4, B2/#1); #A/bB:(3，7).

3. to sum up, it is either accurate to pull it up and feel like re and la, just relative pitch. Want to fly solo, just make do. If you want to play an ensemble, you must tune it with the standard sound la and tune it to the true pitch of re and la.

Tuning method of erhu strings

1, approximate key: A sound (440HZ) using a small group of standard pronunciation devices (pitch controller, whistle, tuning fork, etc.). ) is the standard sound, which is it? 5 in d? So sound. By rotating the outer chord of the erhu, (if it is low, tighten the strings; If it is high, loosen the strings). Then adjust the inner chord to d in the same way as the standard pronunciation machine? , which is 1 in d? Do what? Sound. The pitch of erhu is 1? 5? Very harmonious. It's the same as the sound generator.

2. Fine-tuning: Will the electronic tuner? The mode is "erhu tuning mode", put it near the erhu drum, and then pull the slow longbow of the outer string with relatively uniform force (be careful to control it well, too weak or too strong will affect the tuning). The pointer will swing left and right on the instrument according to the slight change of sound. The pointer is between 0 and -50, and the red light is on, indicating that the sound is low; When the pointer is between 0 and +50, the red light is on, indicating that the sound is high; When the pointer is in the middle of 0 and the green light is on, it means the sound is accurate.

3. Several factors affecting the erhu pronunciation:

Bowing strength;

External environment (to be quiet);

Erhu's weight line is aging (often manifested as the pitch difference between the empty string bow and the push bow, and the push bow is low).

Extended data

Methods of mastering the intonation of erhu

1, align

Whether using traditional Andhadhun or electronic organ, the accuracy of the player is very high. If you are not sure about the fixed pitch, especially for beginners, it is recommended to download special erhu tuning software on your mobile phone, and the accuracy of the software even exceeds the human ear.

2. The finger distance changes too much or too little.

The most common thing is that when playing semitone, the finger pitch is often wide, which makes the two too big.

Because the tuning classics of erhu often change the fingering of semitone, such as d? A semitone between two or three fingers; g？ The original semitone is between the first and second fingers of the outer string, and the inner string is between the second and third fingers; f？ The semitone of the keys is between three and four fingers, so we should strengthen the practice of modal scales according to the fingering of different keys, and pay attention to the changes of the fingering distance of each key.

3. Changing the handle is easy to get out of tune

Moving too much or not in place when changing the handle will cause inaccurate sound. To ensure the accuracy of changing the handle, players should have the concept of pitch after changing the handle.

4, the sound of kneading strings is not allowed

When beginners learn to knead strings, because they can't grasp the unity of the amplitude, speed and weight of strings, their voices often drift. At this time, the amplitude, strength and speed of wrist and palm vibration should be controlled by auditory adjustment until the strings make a harmonious and pleasant sound.

5. It is important to listen more.

This is necessary for learning all musical instruments. Only by listening more can we form a fixed and correct melody direction and each pitch in memory, and the accuracy of each note can be determined by this memory when playing. In the process of practicing a piece of music, only by listening more can we compare our mistakes and correct them in time.
