don't call me singer

Chapter 262 "Song of the Science of Music (dou) (bi)"

Gu Xiaobai on the stage was not in a hurry, he turned around from the projector, typed out the lyrics while thinking, and then taught them over and over again earnestly, until the audience was almost sung and the lyrics were basically sung correctly. Continue to the next paragraph.

"Yo~ yo~
Vacuum inside the glass cover,
The bell is placed in the middle,
Sound is transmitted because of air,
Shaking in a vacuum is useless.
To calculate pressure and volume,
V equals C divided by P,

With Robert Boyle,
The word law was born. "

Everyone learns this section relatively quickly. I will learn this, junior high school physics!

Teacher Xiaobai, why didn't you teach me how to sing when I was in junior high school!
Is it still too late to go back and take the junior high school physics exam?

"And Galileo Galilei,
Combining experimentation and mathematics,
explain pitch and vibration,
Prove that the fifth degree is harmonious,
With pendulum isochronism,
There are modern watches and clocks. "

So Galileo was a musician?
Isn't he only throwing iron balls?
Ah hey!Congratulations to Galileo for breaking the shot put world record!Everyone applauds him!

After singing here, everyone feels a little interesting.

I didn't listen to it at all just now, and I didn't remember it when I heard it, but now I suddenly have a little impression.

On the stage, Gu Xiaobai stopped.

Can't always rap.

A song must have a hook!
What about the chorus?
Gu Xiaobai frowned and thought for a while, then remembered the profit and loss process of the three-point profit and loss method just now.

按照宫生徵、徵生商、商生羽、羽生角来排列一下曲调的话，就是1、5、2、6、3。

It sounds a little weird... Well, it's better to change it into a levy, that is, 1=G, it becomes 1, bass 5, 2, bass 6, 3 on the C major keyboard, there are up and down, it sounds slightly It sounds better.

Then use this 15263 as a motivation to build a melody.

Once you have a motive, no matter whether the motive sounds good or not, you can use various methods to develop it and turn it into a phrase.

Then there are phrases, and the rest is even simpler. It can be repeated, it can be stepped up and down, its interval can be expanded or compressed, it can change the beginning and the end, and the end and the beginning...

But Gu Xiaobai doesn't need it here, he just wants to simply repeat and brainwash!

It's too complicated for students to learn.

Gu Xiaobai played a few times on the piano with both hands, found a simple melody, and Gu Xiaobai sang:
"Mason measures the speed of sound, Hooke determines the frequency,
Newton lays the foundation, and waves become equations.

Crani pattern, sound becomes pattern,
Plate Vibration Equations, Sophie Germain,
If you ask about membrane vibration, you also need to look at Poisson.

Fechner's laws, Helmholtz motion,

Psychology and acoustics have only been combined since then.

Summarize previous works, Rayleigh surface waves.

Andronov, and Hopf,
Self-excitation will vibrate and the system will fork.

Science and music have never been separated.

Learn this song and you won't fail the exam. "

The three-point profit and loss method is the most traditional Chinese pentatonic tone, because there are no semitones and dissonant intervals, and any two tones between them sound good.

Some musical instruments sound nice no matter what because they use the pentatonic mode.

Take the guzheng for example, just playing it casually can make people intoxicated, because no matter where it starts, no matter how you listen to it, it will always be in tune.

Another example is the black keys of the piano, which is the pentatonic mode, which sounds good no matter how you play it, and is very in line with psychoacoustics.

In other words, it is easy to write songs in pentatonic mode. In fact, most of the traditional Chinese songs are written in pentatonic mode, because it is very simple to write in this way, and there will be no unpleasant sounds.

But it's just monotonous.

It was not until after 2000 that this phenomenon changed slightly, and more emotions and expressiveness were introduced into Chinese pop music.

But if you only write a catchy chorus, the pentatonic mode is enough.

But no matter how nice the pentatonic mode is, the melody direction of 15263 still seems a bit weird...

In other words, frivolous and teasing.

In particular, the interval between 15 and 26 is the same, and suddenly there is a 3, which feels unstable.

It's like someone jumping one step after taking two steps, it's not safe at all.

The chord, Gu Xiaobai originally planned to start directly with 15263, but it sounded a bit dissonant, so he changed it and changed it to 1625 chord, which is a common chord in country music.

Thus, a song with a combination of Chinese and Western elements, Chinese-style tunes and country music-style chords, and mixed elements, just appeared.

In the first half of this song, it feels like a serious professor in a suit is sitting on the stage, knocking on the blackboard and teaching everyone to sing rap.

Being able to knock out the rhythm and sense of rhythm on the blackboard is considered amazing.

But when the chorus started, the feeling changed all of a sudden.

Just like this professor in a suit and leather shoes with a big back, suddenly took off his coat, played the guitar and twisted Yangko.

emmm, it's too magical.

Dude are you kidding me?
People in the audience: "emmmm..."

Why is it so strange?
The song written by Teacher Xiaobai is so strange!
The lyrics are weird, and the melody is also a bit weird.

Pfft, I can't help it, I want to laugh!
But listening to it, they couldn't laugh anymore. Why do I think such a strange song sounds good? ? ! !

What should I do if I can't help but want to sing along?
So magical, so magical, so magical!
Teacher, is my aesthetics finished?Shall I buy him a coffin and bury him?

And... the lyrics are so difficult!

very long!

After singing the chorus, Gu Xiaobai looked up and asked everyone, "Have you learned it yet?"

"no!"

"Teacher, sing it again!"

"The lyrics are too long!"

Gu Xiaobai said: "Then I will teach it again, everyone should study hard! If you can't learn it, you will be delayed!"

"Good~"

Sing it again: "Have you learned it yet?"

"No!" He said confidently.

"Teach me again!"

"Yes, five more times!"

"Ten times will do!"

Please drag the hall, please drag the hall as much as you like.

It is also very happy to see Mr. Xiaobai dragging the classroom!

And there is Teacher Xiaobai teaching singing!
Wang Haixia was next to him, covering his mouth and holding back his laughter, and taking crazy pictures with his mobile phone.

This is probably the song with the most serious lyrics written by Gu Xiaobai, but the most amusing tune.

This combination makes people laugh.

And now is probably the most chaotic scene of Gu Xiaobai's performance.

Gu Xiaobai is not performing on stage now, he is in class.

The dominant stage performance in the past is completely gone.

Of course, that oppressive force is gone.

Gu Xiaobai on the podium blinked blankly with a question mark on his forehead.

"?????" Why don't you know it!Why not?Is there something wrong with my teaching method?
I've already written songs, hey!What else do you want!
Teaching is so difficult... Senior Brother Xiao Su is amazing, he has to face so many students.

Deep self-doubt.

Up to the duck head.jpg .

If it wasn't for a little shame, the fans of Big Wave Aunt in the audience would rush to the stage to pinch Xiaobai's face.

Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahhhhhhhh

Why so cute!
What should I do, I really want to bully him...

Am I a bit perverted and a bit bad?

Especially in the audience's interaction below, adding and changing words randomly, Gu Xiaobai's face turned dark when he heard it.

Seeing that Gu Xiaobai had turned into Gu Xiaohei, Wang Haixia laughed so hard that he fell down.

You are so good at bullying Xiaobai, please bully more!
Gu Xiaobai is a serious person, he is still young, he didn't realize at all that many people in the audience were teasing him, they just wanted to hear him sing more.

Jiang Wei stood up several times, wondering whether to rescue Gu Xiaobai.

How pitiful, my lord!
Fortunately, Gu Xiaobai's EQ was not online, but his IQ was still there. After a while, he felt something was wrong.

He looked down suspiciously: "You did it on purpose, right!"

"no!"

"Really do not have!"

"Give me a serious lesson!" Slap the table!

"Okay!" The girls screamed desperately as they stared at the stars in the audience.

Ahhh, Xiaobai is angry, angry!What to do, what to do, are you coming to punish me?
Brother Xiao Su raised the amount with his hands below, and he was sure.

Xiaobai is good at everything, but... definitely not suitable to be a teacher!

After filming for a while, Wang Haixia briefly edited and posted it on the Internet.

"Teacher Xiaobai's new song is here! Come and challenge!"

　In fact, two versions of this song were written. After checking the information, I found out that I collapsed.

　　This kind of song is a high song from a man of science and engineering...but you can still briefly understand the relationship and development history of music and science.
