Pei Ningle's tutoring for Fu Jiu started with how to make equations. But as he talked, the topic changed from equations to chords.

"In fact, music does not rely entirely on inspiration. Many things also require mathematics. For example, chords are the superposition of three sound waves, and of course there are more complex ones, that is, there are more superposition notes, such as four, five, and six notes stacked together. Then the key to the chord is the ratio of the frequency, which is very important..."

Pei Ningle said to himself, while Fu Jiu held his chin with both hands, nodding while listening. As for how much he heard, only God knows.

After listening for a while, Fu Jiu asked in a vague sense of understanding: "So do Sister Xiaole also use mathematics when writing songs?"

Pei Ningle: "That's not true. But when writing songs, you need to use music theory knowledge, and those predecessors who established a music theory system used mathematics."

Fu Jiu asked again: "Then why do we need to learn mathematics? If you want to write songs, learn music theory. If you don't learn mathematics, won't it be okay?"

This question is a bit difficult to answer.

Pei Ningle thought for a while and said uncertainly: "Because learning will make people smarter..."

Fujiu: "Really?"

Pei Ningle: "It should be."

At this moment, Pei Ningle's cell phone ringed. The girl picked up her phone and saw that it was a strange number she had never seen before.

But the sound that sounded after it was turned on was no stranger to it.

"Is it Pei Ningle? I am your mentor..."

"Peng Xiaoya!" Pei Ningle subconsciously blurted out, but fortunately realized that it was not good to call someone's name, so he immediately followed the suffix, "Teacher!"

The celebrity mentor on the other end of the phone smiled and said, "How are you doing recently? Haven't you forgotten how to sing?"

Pei Ningle said with great vitality: "Remember clearly!"

Peng Xiaoya: "Haha, that's great. In ten days, it's my episode. You and the other seven students will compete on the same stage, and it's the song you used to blindly select, but you have to make some changes in arrangement and performance, and become more shining as much as possible."

Pei Ningle simply said: "Tell me, mentor, how to change it better?"

Peng Xiaoya pondered for a while and said, "I think your song can be divided into two parts, the main song part and the climax of the final chorus. You can make the main song more quiet, just like the simplest folk song, just use a guitar, throw away the slightly complicated arrangement. Then add more accompaniment to the chorus part..."

Listening to the instructor's description, Pei Ningle imagined it and hummed casually. While humming the tune, he also imitated the drum beats with the interruption and strong sound of breathing.

Peng Xiaoya's voice suddenly became excited: "Yes, yes, that's the feeling! Hey, have you practiced bbox?"

"No." Pei Ningle subconsciously shook his head, regardless of whether he could see it.

Peng Xiaoya: "Then I think you can practice. The cutest girls play the coolest bbox, and it feels very interesting to think about it!"

Listening to this sentence, Pei Ningle couldn't help but fall into deep thought. Thinking about it carefully, it seems to be quite interesting.

After waiting for a while, Peng Xiaoya didn't hear the response and couldn't help asking: "Hey hey hey? Are you still here?"

Pei Ningle hurriedly said, "It's here, here! That... I'm going to go on stage in ten days. Isn't it too late to practice now?"

Peng Xiaoya: "Of course you can't have time. I mean in the future. You can write such a great song, sing well and look good. There will definitely be many opportunities to go on stage in the future!"

Pei Ningle: "Teacher, you are too much..."

Peng Xiaoya: "No, you are really great..."

Fu Jiu, who was standing beside him, couldn't hear Peng Xiaoya's voice on his phone, so he could only listen to Pei Ningle's words, looked at the slightly shy smile on her face, and sighed secretly - it's really a bit strange for people who make music. Can you be happy if you say something too much to others?

It should be said that it is really worthy of being 'Sister Xiaole'?

Another professional course.

After more than half a year of college career, computer students at the University of Telecommunications Technology have already understood that they cannot take too much water. For example, if professional courses such as mathematics courses and C language are not studied well, then the only way to re-plan the next year. As for the leisurely scenes depicted by high school teachers, they can only be implemented in less important elective courses.

At this time, Wang Heng looked around. Whether it was Fu Hanwen and Wang Ke sitting on his left, or Tang Hexing sitting on his right, they were listening carefully to the lecture and taking notes, showing the seriousness of a high school student.

As for the efficiency of listening to classes, no one knows...

Finally, the bell rang and Wang Heng heard the sound of breathing from both sides, and everyone seemed to feel relieved.

The old professor had no intention of dragging the class and turned around and stepped down. However, the five students sitting in the front row moved faster, and they entangled the professor with the problems on their laptops.

Looking closely, the most active among the five students was the class leader Sun Xingsi.

Wang Ke: "Our class leader, every time we are taking some questions that can be found with Qiandu and Zhihu to find the answers to the teacher..."

Fu Hanwen curled his lips and said disdainfully: "Or why do you think the teacher runs so fast after class? Do you think so?"

Wang Heng doesn't like to talk about others behind his back. After all, it's not easy for everyone, so why bother to expose it? But before he could get over it, Xiao Tang on the other side changed the topic.

Tang Hexing said helplessly: "Don't worry about the squad leader's show of pretending. I'm annoyed now! Do you feel that my little white seems to be a little wrong recently? Is it in heat?"

Fu Hanwen and Wang Ke looked at each other and nodded.

Wang Heng has been in the dormitory for the least amount of time recently and has no feelings about this. He glanced at Tang Hexing's mobile phone and found that the kid seemed to be checking how the female cat was dealing with estrus...

Then at this moment, Wang Heng's own phone vibrated. He took it out and took a look and saw that it was a text message from Pei Ningle:

[We are going to prepare for the second round of the game!]

After putting away his phone, Wang Heng observed his roommates and suddenly realized a problem - they didn't seem to have the habit of watching CCTV programs, nor did they pay attention to the entertainment industry, they did not interfere in the school social circle, and would not go to Tao's bar to listen to music for a long time, so they still don't know what Pei Ningle performed on that program.

Of course, if Pei Ningle performed more outstandingly and became more famous in the next round of the show, then the roommates would know after all. And they already knew about Pei Ningle’s relationship with him, so what should we do then?

Before Wang Heng could come up with a countermeasure, his roommates had already started an in-depth discussion on the topic of female cats in estrus.

Wang Ke: "I heard that I need to undergo sterilization surgery or something..."

Tang Hexing: "I just checked it and it costs several hundred yuan!"

Fu Hanwen: "Tsk tsk, it is obviously a couple who have worshipped the world and are not willing to pay for her even a few hundred yuan. Is this a moral destruction or..."

Tang Hexing: "Shut up!"

At this moment, Wang Heng casually said: "Why don't you try medical cotton swabs?"

The three of them turned their heads and looked at him, their faces full of surprise and surprise.

Imagining the scene of a medical cotton swab and a female cat, Tang Hexing's face turned red.

Fu Hanwen gave a thumbs up: "Teacher Wang, he deserves to be Teacher Wang!"
