The pipa performance of the small test made everyone in the piano room in Beishi have long been accustomed to shouting 666, and they are even a little numb to Jiang Bai's series of pretending performances.

This kind of numbness is reflected in the emotional value, almost without waves, when Jiang Bai is not deliberately playing for the sake of brushing, it is purely an itchy pipa playing.

"Before the recording of the show starts, you should take classes and teach."

Early the next morning, the North City Piano Room...

Jiang Bai had just arrived at the classroom and found a bunch of students and parents at the front desk discussing something with Jia Linlin.

"Don't lie to us, Teacher Jiang is so powerful, why don't you teach piano and violin?"

"We are willing to pay a high price to experience Mr. Jiang's courses."

Several parents spoke to themselves, pointing to the teacher's business card in protest. In addition to Jiang Bai's photo, there is also a pipa instrument that he took on this business card.

In addition, other courses such as piano and violin are arranged from time to time.

The so-called special course is expensive, with a three-hour class at a time, which is a one-time guided course.

A teacher who can enjoy such treatment, the entire Beishi piano room is also qualified by Liu He. This has made Yu Guang envious enough, so far, the new Meng has been brought by him.

Finding that Jiang Bai appeared, several parents gathered around: "Teacher Jiang, when will the special class start?" ”

"Featured class..."

Jiang Bai also wants to make money, but even if the current course is still decided by the Beishi Piano Room, he can't start the class rashly.

Yesterday's youth performance competition, although ordinary people don't care much, but the parents and students of the Beishi piano room also watched the whole game because of Liu He in the group and Yu Guang's Aite.

If it weren't for Aite, these parents wouldn't know that there was such a powerful teacher in the piano room in Beishi.

A pianist who can play with Li Mu is bound to be an excellent teacher. Since you come to class, you have to take the class of the best teacher.

In a sense, Jiang Bai suddenly surpassed Liu He and became the top teacher of the piano room in Beishi.

Jiang Bai waved his hand: "Recently, I have indeed been mainly responsible for the course of the pipa class, and the special course may have to wait for a while. ”

Pipa?

Many parents were stunned for a moment, and then looked at the course arrangement in the pipa column on the business card, and finally believed that Jiang Bai did know how to pipa.

Wait a minute, the North City Piano Room is ready to open Chinese classical instruments?

"Teacher Jiang can also play the pipa?"

"Starting today, there will be a Chinese classical musical instrument interest class in the North City Piano Room, and you can sign up if you are interested."

At present, in China, classical musical instruments pipa and guzheng are also very popular music, and most of the teachers in the piano room in Beishi are mainly Western musical instruments, and there are no teachers of musical instruments such as pipa.

During the previous competition, Jiang Bai's performance made Wu Daozi and the old woman decide to let him temporarily serve as the person in charge of the pipa interest class.

Hearing that Jiang Bai mainly focused on pipa teaching, several other teachers who secretly observed the teacher were also relieved.

After all, no one wants to be robbed of their jobs.

As for Jiang Bai... He himself has a strong interest in the pipa and many local Chinese classical musical instruments.

This interest even includes the interest of the Viennese triumvian classical triumvirate, Beethoven and Mozart.

Trial class?

At this time, the Beishi piano room had already placed dozens of pipas in a teaching room, all of which were common electric pipas on the market.

The electric pipa maintains the national style of the original pipa in appearance, only some electrical components are installed on the panel of the piano case, and the pickup is placed under the strings close to the bound strings, and the vibration of the strings is converted into an electric signal through electromagnetic induction, and then the sound is emitted through the amplifier and the speaker.

In order to avoid reverberation due to resonance, the electric lute increases the thickness of the panel, reduces the volume of the resonance box, and makes the sound quality more pure. The sound of the electric pipa is soft and beautiful, crystal clear, and has rich expressiveness.

In the experience class, Jiang Bai looked at the group of students below, as well as several high-level officials in the Beishi piano room, including the old woman and Wu Daozi.

Although I knew that Jiang Bai's pipa performance was good, I hadn't seen him teach after all, so I was still a little worried.

Jiang Bai didn't have any nervousness, he stood in the center, Beethovenka had a very dazzling aura due to the high synchronization rate.

"The pipa is set to the strings, and there are many variations in traditional music, and the interval relationship between the four empty strings is not fixed. However, the more commonly used method of setting the strings is to fix the four strings from winding to subchord into four notes: A, D, E, and A, which is the so-called C key. ”

According to his own memory, Jiang Bai perfectly displayed the pipa strings in the process of teaching the students below and plucking with his hands.

"Everyone is a beginner, so it's best to learn D first, and the strings are set according to the D key."

In the process of Jiang Bai's elaboration, he asked these students to press the piano when setting the string notes of A, d, e, and a, and set the empty strings according to the pitch of the piano's a note.

Then on the first fret the string plays the e, which serves as the basis for the e-note of the air string. These little students didn't know it at first, but then slowly groped their way out of the door.

Then on the fourth fret, the octave D is played according to the middle string, which is used as the basis for calibrating the D note of the empty old string; Finally, on the first fret, the A note is played according to the old string, which is used as the basis for calibrating the A note of the empty winding string.

After the four strings have been preliminarily set, they should be checked again. In the process of several children's continuous learning and exploration, one of the little girls who had learned the pipa showed a dissatisfied look.

Jiang Bai's calibration method is a beginner's two-tone calibration method, using this method, when it is found that there is disharmony between the two strings, carefully distinguish the pitch of each string, which string is low or high, and then calibrate the strings that are not accurate.

"Teacher... The checksum method you use seems a bit too basic and outdated. ”

The little girl said proudly, with a hint of mockery in her tone, and she didn't know who she learned from, maybe it was the relationship between the female elders in the family.

The girl's mother was a little anxious and reprimanded: "Xiao Duoduo, what are you talking about, this Teacher Jiang is at a high level." ”

Recalling the handsome appearance of his previous pipa teacher, Xiao Duoduo shook his head: "Teacher Han's verification method is much more powerful than his!" ”

Jiang Bai didn't have any mood swings, and with the blessing of Beethoven's cards, the whole person spoke with a sense of stability.

"The main thing is that beginners generally use the two-tone check method, but when they learn a certain level, that is, when they master the harmonic performance, they can use the harmonic check method, which is a more reliable and good method. That is, when arranging products, it is also advisable to use overtones to verify that the grade row sticks to the accurate position. ”

Speaking of this, Jiang Bai showed a bright smile: "Although I don't know what method your teacher gave you, but you can use other verification methods, which shows that Xiao Duoduo is very good and has a solid foundation." ”

Looking at Teacher Jiang Bai's young face, Xiao Duoduo blushed: "... Well... In fact... I didn't... How much have I learned? ”

All of a sudden, Xiao Duoduo's tone became very different...
