Chapter 187 (1/2)
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]

[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.
