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

"Yo~yo~

Vacuum in the glass cover,

The bell is placed in the right,

Sound because there is air,

It's useless to shake the vacuum,

To calculate the pressure and volume,

v is equal to c divided by p,

With Robert Boyle,

The word law was born. ”

Everyone learns this relatively fast, this I will, junior high school physics!

Teacher Xiaobai, why didn't you come and teach me to sing when I was in junior high school!

Is it too late to go back and take the junior high school physics exam now?

"And Galileo Galilei,

Combining experimentation and mathematics,

Explain pitch and vibration,

Prove that the five degrees are in harmony,

With the monopendulum isochronism,

There are modern watches and clocks. ”

So Galileo was still a musician?

Isn't he just going to throw iron balls?

Congratulations to Galileo for breaking the world record in the shot put!

Singing this, everyone thinks it's a little interesting.

I didn't listen to it well at all, and I didn't remember it after listening to it, but now I suddenly have a little impression.

On the stage, Gu Xiaobai stopped.

You can't always rap.

A song must have a hook!

What about the chorus?

Gu Xiaobai frowned and thought about it, and then remembered the profit and loss process of the three-point profit and loss method just now.

If you arrange the tunes according to Miyasheng Zheng, Zhengsheng Shang, Shangsheng Yu, and Hanyu Kaku, it is 1, 5, 2, 6, and 3.

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

Then use this 15263 as a motive to build the melody.

Once you have a motive, whether it's good or not, you can expand it in various ways and turn it into a musical phrase.

Then there is the phrase, and the rest is simpler, it can be repeated, it can be modulated upward, it can be modulated downward, its interval can be expanded or compressed, it can be changed from beginning to end, and ending with the same tail......

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 measured the speed of sound, Hook set frequency,

Newton laid the foundation, and fluctuations became equations.

Klarney pattern, sound change pattern,

Plate Vibration Equation, Sophie Germain,

If you ask about membrane vibration, you also need to look at Poisson.

Fechner's law, Helmholtz motion,

Psychology and acoustics have only been combined ever since.

To summarize the previous works, Rayleigh surface waves.

Andronov, and Hopf,

Self-excitation vibrates and the system forks.

Science and music are never separated.

Learn this song, and the exam won't hang. ”

The result of the three-point method is the most traditional pentatonic form in China, because there are no semitones and dissonant intervals, and any two tones between them sound good.

Some instruments are beautiful because they use pentatonic mode.

For example, the guzheng can be intoxicated by a casual pluck, because it is tuned no matter where it starts, no matter how you listen to it.

Another example is the black keys of the piano, which is a 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, and most traditional Chinese songs are actually written in pentatonic mode, because it is very easy to write in this way, and there will be no unpleasant sounds.

But it's monotonous.

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

But if you want to write just a catchy chorus, pentatonic is enough.

But even if the pentatonic tone is good, the melody direction of 15263 still seems a little weird......

In other words, detached and teasing.

In particular, the interval between 15 and 26 is the same, and suddenly there is a 3, which is a feeling of instability.

It's like a person who takes two steps and jumps a step, and he doesn't live at all.

Chords, Gu Xiaobai originally planned to start directly with 15263, but it sounded a little discordant, so he changed it and changed it to 1625 chords, which is a common chord in country music.

As a result, a song that combines Chinese and Western, Chinese-style tunes and country-style chords, and mixed elements appeared.

In the first half of the song, it feels like a serious professor in a suit sitting on the stage, tapping on the blackboard to teach everyone to sing rap.

Being able to knock out the rhythm and rhythm of the blackboard is also considered to be amazing.

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

Just like this professor in a suit and leather shoes, he suddenly took off his coat, played the guitar and twisted Yangge.

emmm, it's magical.

Dude, are you here to be funny?

People in the audience: "emmmm......"

Why is it so weird?

The song written by Mr. Xiaobai is so strange!

The lyrics are weird, and the tunes are a bit weird.

Poof, no, I can't help it, I want to laugh!

But when I listen to it, they can't laugh, why do I think it's such a strange song??!!

What if you can't help but want to sing along with it?

Good magic good magic good magic nature!

Teacher, is my aesthetic finished? Should I buy a coffin for it to bury it?

And...... It's so hard!

It's so long!

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

"Nope!"

"Teacher, sing it again!"

"The lyrics are too long!"

Gu Xiaobai said: "Then I'll teach it again, everyone will learn hard! If you can't learn, you will have to drag it out!"

"Good~"

Sang again: "Have you learned?"

"No!"

"Teach it again!"

"Yes, sing it five more times!"

"Ten times is fine!"

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

It's so happy to watch Teacher Xiaobai drag the hall!

And there is also a little white teacher to teach singing!

Wang Haixia was beside him, covering his mouth and holding back a smile over and over again, and taking wild pictures with his mobile phone over and over again.

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

This kind of combination makes people laugh.

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

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

The dominating stage performance of the past is completely gone.

Of course, that oppressive force is gone.

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

????? "Why don't you know yet, why not?" Is there something wrong with my teaching methods?

I've written songs, hey, what else are you going to do!

It's so hard to teach...... Senior Brother Xiao Su is so powerful, he has to face so many students.

Deep self-doubt.

Up to the duck head .jpg.

If it weren't for the fact that there was still a little bit of face, the big wave aunt fans in the audience would rush to the stage to pinch Xiaobai's face.

Ahh

Why is it so cute!

What should I do, I really want to bully him......

Am I a little perverted and a little bad?

Especially the interaction of the audience below, adding and changing words indiscriminately, Gu Xiaobai's face darkened when he heard it.

Seeing that Gu Xiaobai had turned into Gu Xiaohei, Wang Haixia laughed and fell.

You guys are so good at bullying Xiaobai, please bully more!

Gu Xiaobai is a serious person, he is still young, he didn't see it at all, many people in the audience were teasing him, and they wanted to hear him sing more.

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

It's so pitiful, Lord Waitre!

Fortunately, Gu Xiaobai's EQ is not online, but his IQ is still there, and after a while, he feels that something is wrong.

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

"Nope!"

"Not really!"

"Give me a serious lesson!"

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

Ahhh

Senior Brother Xiao Su added the amount with his hand below, and he was sure.

Xiaobai is good at everything, but ...... Definitely not fit to be a teacher!

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

"Teacher Xiaobai's new song is here!
