Chapter 187

Lin Yue Jing Leng Shen son's Kung Fu, Li Zheng has already picked up the wooden guitar.

And spread it out on your thighs.

Like the guzheng, the left hand presses the string and the right hand plays.

This operation really surprised Lin Yujing.

The posture of playing the piano is no longer a problem of sound mania, is it?

There is no basic music knowledge at all!

However, Li Zheng himself has a self-contained manner.

Between melancholy.

Even, there was a bit of obsession.

In his mind, this scene is exactly the scene in which the elder Qu Yang of the demon sect and Liu Zhengfeng, the leader of the orthodox school, played in "Xiaoao Ao Jiang Hu".

So he swayed his guitar and pretended to be a Guqin.

If the music is high and few, it is hard to find a bosom friend.

Lin Yue Jing, you taste, you fine.

"Well..." Lin Qijing just sighed, and suddenly felt dull.

It's crazy to expect this pig's hoof just now.

"You'd better play for Jiang Qinghua. I'm off."

Lin Yujing purred on the piano and then fell asleep again.

Li Zheng saw that, this is a little lost, but a little bit of a product, and then wonderful.

In Xiaoao Ao Jiang Hu, Qu Yang and Liu Zhengfeng's song is just a combination of Qin and Xiao.

Lin Yue Jing is not a Xiao guest, but Jiang Qinghua is.

Therefore, she was jealous and said that she should play for Jiang Qinghua.

Li Zheng thought he thought of the second floor, but Lin Yujing was already on the third floor.

In front of such a master, or do not show off.

"Come on, stop it." Li Zheng said he took off his leather jacket and hung it on the back of his chair. Then he rolled up his shirt sleeves with great momentum. "Make sure you want a guitar accompaniment, right?"

Lin Qijing just slapped his hand at will, and then fell asleep again.

Li Zheng doesn't pay attention to her any more, so he looks at the relaxing interface.

Lin Qijing is obviously immune to EQ moves.

I can't help it. Let's do it.

[Li Zheng]

[game currency: 25]

[relaxation activity detected: instrument playing]

[vitality recovery rate: 0.3 (playing guitar). 】

[daily recovery limit: 60 minutes. 】

[you can obtain relevant skills by throwing coins -]

[modern music theory: comprehensively master the knowledge of modern music theory. 】(5 game currency)

[breath of Qi: Master whistle, Sheng, suona, flute, harmonica, horn, etc. the performance of musical instruments with "vibration of Qi" as the core is equivalent to the level of ordinary professional performers. 】(5 game coins)

[string ringing refers to playing the piano, erhu, guzheng, violin, guitar, etc., with "string vibration" as the core. 】(10 game coins)

[the power of membrane singing: master the performance of drum, drum, hand drum and other musical instruments with "membrane vibration" as the core. 】(5 game coins)

Li Zheng looked at these skills and said nothing else.

How impressive.

I really want to order it all.

Unfortunately, the game currency is limited.

I'm afraid it's only by taking the degenerate route that we can get the whole point.

Now it seems that at least the combination of "modern music theory" and "string ringing finger" is needed.

15 game currency although some heartache, but the future more a daily relaxation project, is also excellent.

Li Zheng no longer think much, smart coin, skills into the library.

With the arrival of new knowledge, Li Zheng's eyes widened and became more wonderful.

A few seconds later, Li Zheng had already rubbed his cheek and sighed: "so it is..."

He always thought that music was a mysterious art discipline, and tried to understand it sensibly.

But in fact, this is totally wrong.

It's a big mistake.

The essence of music.

It's math!

And a little bit of physics and materials.

The reason is very simple. All sound is based on the vibration of matter.

The material of matter determines the timbre.

The frequency of the vibration determines the tone.

The interval of vibration determines the beat.

The mixture of vibrations is music.

In this, except for the material, all the other problems are simple problems of proportional sequence.

For example, a piano octave has a total of 12 keys, do to Si, seven white keys, and five black keys.

Among them, the first key C, that is, do, is the conventional starting point of the scale, which sounds comfortable. Its vibration frequency can be measured as F0.

After that, according to human hearing habits, the vibration frequency of the last tone B of this scale, namely Si, should be 2f0, which is just double.

The first and last vibrational frequencies are determined, and the rest is to divide the frequencies of the remaining 10 notes equally.Intuitively, it seems that we should use the arithmetic sequence to make the frequency difference of each tone 112.

But in fact, the human ear distinguishes the height of two sounds by the frequency ratio between the two sounds, not the frequency difference.

A normal person can clearly distinguish between 50 Hz and 55 Hz, but it is difficult to distinguish between 5 000 Hz and 5 05 Hz.

Therefore, we have to use the equal ratio sequence to divide equally.

According to junior high school mathematics, the direct frequency ratio of each tone in this sequence should be 2 to 12.

That is 1.01530947.

With this ratio, we can make an octave scale.

This is exactly the twelve temperament commonly used in modern music theory.

It was first created by Zhu Zaiyu, one of Zhu Yuanzhang's grandchildren.

It's a bit scary to say that one, two open 12 times root.

In order to calculate this, he did not hesitate to make a set of 81 digit abacus.

As for how long, no one knows.

Salute the math guru.

By the way, Pythagoras, the inventor of the earlier ancient temperament, was also a great mathematician.

At this time, Li Zheng thought of the staff, the beat, the rising and falling tone.

Between the lines, inside and outside.

It's all math!

"Wonderful For the first time, Li Zheng found music so interesting that he couldn't wait to pick up his guitar and start tuning.

For beginners, this process often requires a tuning fork or a tuner to determine the reference tone.

But Li Zheng, an ordinary professional performer, can recognize by his ears alone.

Thinking that every time you tighten the string, the vibration frequency of the string will have a wonderful change, rippling with the beauty of mathematics, Li Zheng is also more and more powerful.

He went back and forth, comparing the "thump" sound of each string, and his mind was full of proportional sequences.

Hearing the sound of tuning, Lin yuejing, who was sleeping on his stomach, twisted a little, as if in a classroom, peeping through a reasonable gap.

Li Zheng's face was flushed, twisting left and right, and mumbling about the root opening.

It's all weird.

Lin was also shocked.

How can you play a piano to make Olympic Mathematics?

She can't help but twist a few angles, conveniently plucked her hair, exposed her left ear, and listened carefully.

If someone else, I'm afraid I can't hear anything.

But Lin kuojing shivered as soon as he heard it.

Deng -

the first string, high pitch MI.

Deng -

the second root is the middle tone Si.

Deng -

the so of the middle tone.

……

Sixth, bass MI.

Yes, it's all right.

It's right!

In amazement, Li Zheng suddenly raised his head and rolled his eyes. Relying on his intuition, he stares at Lin Qijing's left eye, which is peeping into his hair.

Internal skill has been achieved.

Let's fight!

This time, Li Zheng made no effort to open his mouth: "have you found the score?"

Lin Yue Jing's heart suddenly quickened and he was frightened to sleep.

That's not good.

Li Zheng frowned and said, "how many meanings do you mean? Don't you ask me if I can play guitar and want to have a duel?"

"I I... " After struggling for a moment, Lin Qiaojing suddenly clenched his fist and ran straight to the door. "I'm thirsty. Go get the kettle."

Li Zheng did not expect that a person who had been sleeping on his stomach could "whoosh" and disappear.

However, at this time, he just realized the magic of mathematics and music. He was in a good mood, but he was not angry. In the end, he played with Jiang Qinghua's Qin and Xiao. It's not bad to think about it.

Outside the classroom, Lin Yue Jing didn't go for a kettle, but ran to a row of bungalows in front of the innermost tree, supporting his waist to gasp.

In fact, she didn't want to win honor for the school, nor did she play tricks on Li Zheng.

It's just a simple fear of the crowd.

It is different from Li Zheng's heroism of "blame me for growing up like this, you can look at it at will".

And Zhang Xiaoke that kind of "ha ha ha ha, sure enough I am the most lovely ~ ~" that kind of masturbation is also different.

Lin is very afraid of being watched.

Not to mention being watched by so many people.

Not to mention being watched with Li Zheng.

Playing basketball on the playground is her limit.

Performing in public, in front of people from other schools, she still couldn't make it.

Between gasps, the electronic sound effect of "rocket in orbit" comes from the pocket of the sweater.

Lin Qijing ears a stand, some tangled out of the mobile phone.

This is actually the wechat prompt tone, which is equivalent to the "Deng Deng Deng" of other people.Lin yuejing thought it was a message from Li Zheng. Unexpectedly, the sender was [(rocket) Mom (rocket)].

Of course, this is actually the remark she set up, which is actually her mother Shen Tinglan.

Mom: someone has a birthday tomorrow. 】

[Lin Qijing:??? Are you in June? 】

[Mom: (smiling) Yes, on December 25, who else? 】

[Lin Yujing: Jesus? 】

[Mom: guess again. 】

[Lin Yujing: Grandfather Mao? 】

[Mom: (covering her face and crying) it's Li Zheng. 】

[Lin Qijing:??? 】

[Mom: I happened to see it from his father's circle of friends (whistling)]

[Lin Yujing: cheating, you never look at the circle of friends! 】

[Mom: the experiment is about to start. It's off. 】

[Mom: by the way, I can't come back before 12 o'clock. You can eat by yourself or with your classmates. 】

[Lin Yujing: you shut down! 】

[Mom: (kissing) (kissing) (kissing)]

putting away the mobile phone, Lin Yu was very calm.

Why should you suddenly inform people of such useless news?

What she didn't know was that Li Zheng was also watching his mobile phone in the music room.

[Lao Li: I forgot to talk about it just now. Do you remember what day tomorrow will be? 】

[Li Zheng: That's so annoying. 】

[Lao Li: I don't blame you, my pot. I didn't expect to be so precise on this day. 】

[Li Zheng: what's wrong? 】

[Lao Li: there are several major operations today, they can't go back before 12 o'clock. You can ask your classmates to celebrate their birthday, and I'll give you reimbursement. 】

[Li Zheng: Oh. 】

[Lao Li: so Do you have a date? 】

[Li Zheng: aren't you busy with surgery? 】

[Lao Li: aren't you in class? 】

[Li Zheng: biology class. 】

[Lao Li: Oh, oh, that's it. 】

Li Zheng put away his mobile phone, and his original good mood was completely destroyed by old Li.

It's annoying to be born in Japan.

It's still the awkward time of December 25.

Don't let the students know.

Li Zheng's mentality had just been adjusted a little, then he saw Lin Qijing slip in, and in a twinkling he was lying on the piano.

Li Zheng also ignored her and tried to tune the strings.

A moment later, Lin yuejing suddenly stamped his foot.

Li Zheng raised his head and said, "eh?"

Lin Qijing was silent.

Li Zheng shook his head and continued to rub.

Before long, it was another "Dong" stomp.

Li Zheng looked up again: "mm-hmm?"

"You..." Lin Qijing pinched it for a moment and squeezed out a few words. "You said it yourself."

"Say what?"

Bang! Stamp your feet again.

Li Zheng thought about it for a while, and soon he laughed.

Sure enough, when she heard my music, she couldn't help but want to cooperate.

But before that, it was so different.

Now, I just want to find a step.

"Well, I say." Li Zheng raised his hand and said with a smile, "I want to cooperate with you. Could you please find a guitar accompaniment score?"

Lin qiojing didn't stamp her feet at last this time. She twisted her body and looked at her eyes from her hair: "that Then you have to On November 1st, remember clearly... "

“？？？” Li Zheng a face puzzled, "did I not listen to a sentence?"

Dong Dong Dong Dong!

Lin Qijing stamped his feet three times.

"Scum! Stupefied! Pig! Hoof! Son

“？？？” Li Zheng fell into a profound reflection.

I have to pay it back?

What else?

November 1st?

What is this

Wait

Is

"You Know me Tomorrow? " Li Zheng swallowed and vomited.

Lin Yue Jing did not speak, indicating acquiescence.

"So, you are in November One? "

Stamp your feet! I'm sure.

Li Zheng understood the situation just now.

She's swapping birthday presents in exchange for performances.

Well, what a childish woman.

But then again, this time she did ask for Lin Yue Jing. She exchanged this for her birthday present in the future, but she didn't say that.

"Good, good. Deal." Li Zheng generously nodded, "November 1st, right? I remember. "

"~ ~ ~"

"what do you shake?"

When Lin Yue Jing felt comfortable, he sat back straight, straightened his hair and said, "well You play a piece of etude first, and you have to pass the testWhen Li Zheng heard the speech, his eyes glared.

Everyone panicked.

Although he is a master of music theory and a professional string player.

But actually.

Not a single song.

It's like a master with top-level internal mental skills, but he can't even fight Military Boxing.

It's embarrassing.

Lin Qijing saw this and said, "ha! It's a pig's hoof that can only tune. "

"Damn it..." Li Zheng scratched his head impatiently.

No, I can't. I'll play something.

Think about it.

The most familiar melody.

It can only be that.

It's going to be about that melody, and it's going to pop up.

According to the mathematical principles of musical matching and the mathematical principles of chords, supplemented by commonly used music sets

Li Zheng bowed his head and kneaded the thickest two strings with his left hand.

The right hand claps the body twice, finds the beat, cuts in at the right time, and quickly picks up two thick strings with the thumb.

With a sense of bass accompaniment "bang bang Deng" sounded.

Although it's played on the guitar, this fast-paced bass is like bass.

This series of fast plucking string, also surprised Lin Yue Jing medium hair, slightly open mouth.

But it didn't last long.

Because Li Zheng began to sing.

"Two tigers..."

"Two tigers..."

"Run fast (broken sound)..."

Half a minute later, the song "two tigers" was finished.

Li Zheng pressed the string to receive the voice and looked up: "hum, how about it?"

Lin Qijing is still in the middle state of "fried hair" and "let me die", and can't say a word.

God level accompaniment, with the ghost like singing, this feeling is like eating a cheese cake with soy sauce.

After a long time, Lin Yujing said what he wanted to say half a minute ago: "you still Don't open your mouth. "

"Oh?" Li Zhengmei color a Yang, "that is to say, are you satisfied with my fingering?"

Although reluctant, Lin Yue Jing still bit his lip and nodded: "have a try..."
