"Today I would like to introduce to you the modernist composition techniques, one of which is the twelve-tone system." In the small music room, Yin Dixiao began his endless waves. For some reason, lecturing always appealed to him enough, and the man had endless strength as soon as he stood on the stage.

He was originally very interested, picked up the ** pen and was about to make a statement on the blackboard, but saw He Beifan looking elsewhere with dull eyes, looking thoughtful but didn't know what he was busy with. In fact, Yin Dixiao had already discovered that there was something wrong with He Beifan's state, and the young man looked very sad as if he had something on his mind.

"Beifan, He Beifan." Yin Dixiao knocked on his lectern with some dissatisfaction, and looked at Beifan's face fixedly, "You can introduce the twelve-tone system to everyone." His tone was already very serious, but He Beifan didn't seem to hear it, and the expression on his face was dumbfounded. At a glance, you can see that Beifan's mind is not in the classroom at all.

"He Beifan, get up and introduce what is the twelve-tone system?" Yin Dixiao looked at him with a little annoyance, and patted the blackboard eraser in his hand. But the young man obviously didn't notice that the man was looking at him, He Beifan was now full of only what his mother said to him last night, how could she think of herself like this, the more Beifan thought about it, the more aggrieved he felt. He didn't notice that the eyes of the whole class were focused on him alone.

Ren Shupeng had already taken out his pen, intending to write something down. He's not good at music theory, and it's good to rap, but these boring dead knowledge doesn't suit his appetite. Originally, I wanted to take advantage of the class to remember more, but now I was disturbed by He Beifan. To his surprise, the boy next to him didn't notice it at all, and he was still sitting next to him looking as safe as a mountain. He Beifan's posture made Ren Shupeng really angry. He has never been nosy, but now he can't sit still.

He pushed Beifan's arm, "Hey, what are you thinking, the teacher is calling you?" He looked at He Beifan with some anger on his face, but Fan was slowly relieved by his push, "Huh? What's wrong? He looked confused, and the whole class laughed when he looked so stupid.

"Tell you to get up and answer the questions." Ren Shupeng put down a sentence quite impatiently, not knowing how disdainful he was for He Beifan. He has always had no good impression of students who run out of class hair, and Fan is naturally no exception in the hearts of his scholars. Seeing that everyone was looking at him, Yin Dixiao also had a cold face. He Beifan suddenly realized his faux pas, and hurriedly stood up from his seat, he could feel his cheeks a little hot.

The laughter of the class had subsided a little, but the dozens of pairs of eyes were still staring at him. Deng Wen, who was sitting in the back row of the classroom, was even more so, the corners of his mouth couldn't help but rise, as if he was waiting for a good show. He was a little afraid that Yin Dixiao would be eccentric, but looking at his appearance of "six relatives don't recognize", he really didn't mean to spare He Beifan easily.

Beifan knew that he had done something wrong, he bit his lower lip, and he had never felt such a panic. He didn't dare to look at Yin Dixiao's eyes, the man must be very disappointed in himself now, but it is not a way to continue like this. Forget it, it's better to admit your mistakes first, thinking like this, Fan strengthened his courage again, "I'm sorry, I didn't hear your question clearly, can you repeat it again?" ”

Seeing him say this surprised Ren Shupeng, he usually spoke to Yin Dixiao with respect, and never dared to make such an rude request, I really don't know where He Beifan got the guts. He even cast a praising glance at his fellow tablemate, but at the same time, he looked at Yin Dixiao's face quite worriedly.

"Hmph." The man standing on the podium sneered, he has always been very open to He Beifan, so sometimes he turns a blind eye to some of the boy's mistakes. But it's clear that he doesn't want to do that now. Yin Dixiao cleared his throat, and there was something difficult, "Didn't you hear clearly?" Or didn't you listen to what I was saying at all? His voice suddenly rose an octave, and such a posture startled the students under the podium, they had never seen Teacher Yin so angry. In the children's impression, their homeroom teacher is a good talker. Yin Dixiao is not very old, he looks polite, he likes to laugh, and he can always mingle with the children after class. Naturally, the teenagers have never seen a man's fierce and vicious appearance, not to mention that He Beifan is his protégé. This kind of trouble happened to Fan, which made the students more or less unbearable.

But obviously Deng Wen didn't think so, he still casually turned the original ballpoint pen in his hand, looking light and light, and the years were quiet. It seems that he is still very afraid that this matter will not make trouble, and he belongs to the kind of people who are afraid that the world will not be chaotic. Looking at He Beifan again, he was so nervous that he couldn't speak, and cold sweat began to break out in his palms.

"He Beifan, what are you asking me to say about you?" Yin Dixiao sighed helplessly, he gritted his teeth, and it could be seen that he was trying his best to control his anger, "Do you think that you studied very well and you don't have to listen to the class?" The man's words showed no mercy, but he did see it that way in his heart. He then pressed his big hands on the lectern, like an angry lion.

"No, it's not." He Beifan did something wrong, but he really couldn't accept such an accusation, "I'm sorry, I was really a little hairy in my thinking just now." Bei Fan stood there feeling extremely embarrassed, his thoughts had been very chaotic lately, and he didn't know what he was thinking.

"Not so? Then why don't you listen, where is your heart? Yin Dixiao was really not used to scolding students, but today he really couldn't control himself, he rolled his eyes at the embarrassed boy, "Okay, you said that's not the case, then please answer me a question." The more Yin Dixiao spoke, the more excited he became, and his attitude became more and more impatient, "What is the twelve-tone system?" Don't you listen? Then you must know, so you can answer it. His tone sounded extremely arrogant, and he didn't know how many points he had deducted from He Beifan in his heart.

The class was completely quiet at that moment, and all the students held their breath, and they couldn't help but pinch a cold sweat for He Beifan, who was standing. Of course, there was no lack of Deng Wen's mouth with a smile that was almost contemptuous. The room was so quiet that only the ticking of the clock on the wall could be heard. But such a small voice was enough to disturb He Beifan's train of thought at this time.

The boy seemed to have never been so flustered, obviously he had already dabbled in knowledge, but now he couldn't think of anything, and his brain was even more blank. Beifan's heart was beating fast in his chest, as if it was about to jump out.

"Why, it won't." Yin Dixiao sneered, this was the man's wish, "If you don't, stand behind with your book now and listen, go." The man's order made Ren Shupeng dissatisfied, which was a knowledge point they had never been exposed to. Yin Dixiao obviously knew that He Beifan would not make things so difficult for him, so what kind of ability was it.

At this moment, Deng Wen should be the happiest person in the entire music room. He was really proud, and when he saw Beifan being punished, he even had a feeling of "great joy". But He Beifan was not so powerful, he still stood firmly in his seat like a wooden stake. But his eyes have become a little calmer, and he is no longer as flustered as he was. The numb-like thoughts seem to have been sorted out in this short period of time.

Yin Dixiao was originally angry, but when he saw He Beifan ignoring him, he felt that he was about to be angry, "What do you mean?" There was an obvious anger in the man's words, "He Beifan, I asked you to stand in the back, did you hear me?" You're special, aren't you? Seeing that Beifan still didn't react, Yin Dixiao counted without stopping, "Hurry up, don't delay everyone's time." ”

Ren Shupeng also patted He Beifan's arm, he didn't understand why he was so stubborn, "Go ahead, don't be angry." I thought that under my own persuasion, He Beifan would get out of his seat. Unexpectedly, the boy did react, but it was not a physical expression.

"The twelve-tone system is one of the modernist compositional techniques. It was founded in 1921 by the Austrian composer Schoenberg. The composer abandons the traditional system of key, tonality and harmony, and arranges the twelve notes in the chromatic scale into a one-year sequence, and then treats them with techniques such as inversion and retrograde, and no note can be repeated unless all the notes have been present. He Beifan finished speaking in a hurry, without pausing, as if he had been thinking about it in his heart for a long time.

In fact, He Beifan was just nervous, but when he adjusted his breathing, the knowledge construction that had been constructed in his mind clearly appeared in front of him. Therefore, when the boy finished talking about it in one breath, he felt inexplicable confidence.

The group of children in the music room were not to mention how surprised, they sighed a few times and then applauded Beifan in unison. This made Yin Dixiao, who was standing on the podium, suddenly confused, the man had never encountered this situation in such a class for such a long time, and he couldn't help but glance at He Beifan. But for a second he felt very faceless, "What are you applauding?" He had to feign anger again, "Will he be great?" That's what he should be. He turned to He Beifan again, "You sit down." ”

Beifan was originally a little worried, but he saw that the corners of Yin Dixiao's mouth were close to the arc of a smile. This time, he slapped Deng Wen hard, "Damn, this kid, how is it possible?" He threw the pen in his hand on the desk in annoyance.
