Looking at Li Wenyin who was smiling, the judges couldn't help feeling guilty, just like a child who was checking homework by the teacher.

I could have discussed something easily and happily before, but now...

Don’t dare to move, don’t dare to move!

"Mr. Li, you are busy!"

A judge chuckled and didn't know what to say, and the scene suddenly became a little embarrassed.

"I'm not busy!"

Li Wenyin looked at several judges and touched her nose.

"I'm just wondering what you are doing, give me Kang Kang?"

"Oh!! That happens to be Mr. Li here!"

The judge was stunned and immediately said ecstatic.

"There will be a report performance after this competition. Princess Elizabeth will come to visit as a royal representative. The performance process has been determined, but..."

Several judges looked at each other, nodded to each other, and said.

"In the report performance, the judges also need to perform... We are discussing the project we perform."

Oh, waiver?

Li Wenyin was stunned and then burst into laughter.

Good guy!

The judges will also be evaluated!

You guys have today too?

"Mr. Li, you are here. Why don't you... after the competition is over, please show us?"

The judge, who looked in his forties or fifties, had a strange expression.

This time the relationship is even more messy.

Will the contestants who judge themselves give advice to themselves at the end of the game?

But I didn't think something was wrong.

But it just seems something is wrong.

“Um…”

Li Wenyin thought about it.

Although it feels a little weird, it seems nothing is wrong.

But...what if he is polite, will I seem arrogant and unremarkable?

If he really thinks so, will it make me look pretty pretentious if I refuse?

"Haha, the strength of the judges certainly doesn't require me to talk too much, but it is my honor to watch the performances of the judges."

Li Wenyin recruited Bird's tail on the spot.

Smiling and saying what everyone loves to hear.

"Hahahaha! Mr. Li is modest!"

Several judges were obviously a little ashamed, but in addition to being ashamed, they seemed to be a little happy.

"Mr. Li, I've always been curious...how did you think of those techniques?"

The judges were very curious.

To be honest, I don’t know how Li Wenyin came up with many skills beyond imagination.

"This is simple!"

Li Wenyin smiled.

"In fact, if you follow the techniques and trace it back, it is actually the interference of different movements of the left and right hands on the strings and bows, creating different overtones and resonances. You just need to think about whether there are other pronunciations and whether they can be used on some music."

"So that's the case. It seems that we have to study marginal disciplines a little too!!"

Several judges suddenly realized.

"Yes, if you only study music, maybe many more wonderful things will be ignored!"

Li Wenyin nodded with deep emotion.

Fringe disciplines sometimes positively promote the development of this discipline!

For example, only studying ophthalmology or studying neurology must have its own limitations.

However, doctors who are mainly engaged in ophthalmology or neurology have some research on neuroophthalmology and will also have a huge improvement in their subjects!

The subjects that are related to musical instrumental performance are somewhat incompatible.

That is physics and kinematics!

Especially kinematics.

Describing and studying the mechanical branches of the law of changing the position of objects over time from a geometric perspective will actually be of great help and breakthroughs for the performance of such string music.

Just like playing musical instruments, you have to study the direction and control of airflow, and even analyze the structure of the human body, study pores, ventilation and other methods to pave the way for better performance.

If you only learn half of it or have not studied to a high level, you will not be able to understand another sky here!

"Look, for example, when playing the real sound, how does the noise of changing the bow originate?"

Li Wenyin picked up a pen, found a piece of paper, drew two circles with different arrows, and cut a straight line on the side of the circle.

Figure 1.

Figure 2.

"Look, this is the vibration trajectory and kinetic energy movement direction that occurs when we play the up and down bows when the strings and the bows rub! "

Although it seems a bit complicated after figuring out the picture, it is actually very easy to understand these judges.

"The movement direction of the upper bow and the lower bow are different, and the vibration direction of the string is also different. Therefore, if we are more impatient when changing the bow, we will quickly switch to the opposite counterclockwise vibration when the string rotates clockwise!"

"So, at this time, if you are not skilled enough, it is easy to generate noise, or the second note should start with a strong and gradually weaker, but it plays into a weak and weaker, gradually weaker!"

Li Wenyin smiled.

"Of course, the theory here actually has a relatively small impact in reality. If you practice hard, you can still pull it off even if you don't understand it. However, if you change to more advanced techniques, such things are very necessary to study!"

This sentence immediately made the judges very concerned!!

That's right!

What is most shocking about Li Wenyin is far more than the magical bowing technique and the left hand plucking strings!

What shocked the insider even more was his accurate and beautiful overtones!!!

"Yes, it's the overtone!"

Li Wenyin said to the judges.

"Look, when we are real, we press the string with our left hand and press it down on the fingerboard!"

"But the overtones are just gently placed on them and do not press them, so the pronunciation will become false."

"This is a natural overtone. The four basic natural overtones are very simple to understand, but above this, artificial overtones seem very difficult!!"

Li Wenyin continued to draw a picture on the paper.

The left and right are used to describe the piano code and the pillow, and two intersecting arcs are drawn in the middle, which are ∞-shaped!

Figure 3.

"Look, the intersecting wave joints in the middle are the touching points of the finger when playing overtones!"

Li Wenyin explained very simply.

"The real sound is to let the fingers constantly press on the fingerboard, creating vibrating strings of different lengths and creating different sounds. In other words, the lower part of the finger pressing point will vibrate under the pull of the bow, and the part between the fingers and the pillow will not vibrate!"

"The overtone is not pressed firmly by fingers, so when playing overtones, the whole string will vibrate!!"

Damn it!

Good guy?!

The judges looked at each other, a little stunned.

"I know this, but is there any problem?"

Perhaps for the public, no one cares about the vibration mode of overtones and the vibration mode of real sounds.

Even for many people who learn violin, the majority of people who don’t know this principle are.

Although some performers, professors and others know this principle, they generally don’t know how to study it.

"Of course there is, that's why I can play artificial overtones perfectly, but others can't!"

Li Wenyin nodded.
