For Qin Fangge now, learning mathematics and being able to appreciate the beauty in it is a considerable improvement for him, which is far more important than the score in the exam.

Qin Fangge will be interested in this, also because there are actually many mathematical rules used in music. As he studied Bach's music more and more, the more Qin Fangge could feel the beauty of mathematics in it, to say that Bach was really a god, anyway, after carefully analyzing his works, Qin Fangge felt that his past self was simply weak.

What particularly amazed him was the widely used counterpoint in Bach's works, which could even be compared to a "musical Rubik's cube". The combination between tones and tones, like a Rubik's cube, can be rotated vertically and horizontally to create various collocations. Similar to a card game, 54 cards, four suits, calculated according to mathematical permutations. Then the 12 notes of the music, dozens of rhythms, and the combinations that come out are almost endless.

Bach's more than 1,000 compositions, exhausting the combination of counterpoint, produce rich and emotionally rich polyphonic music. The principle of counterpoint is derived from the principle of harmony of intervals, but it is Bach's imagination that uses it. Bach's keen sense of hearing allows the various intervals to show a spectral and colorful order, in line with mathematical theory, and the colorful intervals are all designed to weave a pattern as exquisite and calm as a Persian carpet. In addition to the cooperation of the sound points, there is also the dislocation of rhythm, the dissociation of tonality, and the transposition of rhythm of the beat...... All kinds of techniques, confusing, and easy.

In the fugue, this expression is even more prominent, with the rotation, separation, intersperse, chance, symmetry, and parallel flow between the voices, every detail is quiet and secure, and every fold and cutwork is delicate, and the brush is clear.

Qin Fangge also wanted to learn Bach's counterpoint technique, but this required stylized composition, and the more rules, the better, although all the pieces such as the prelude and the etude may sound the same thing, but such a large-scale practice made Bach's counterpoint technique perfect. What Bach was able to achieve in the end was to be familiar with the rules, but beyond them. In the end, all the ornamentation, complex structure, and vast scale of his works constitute a magnificent vast sea of stars.

The more he learned, the more Qin Fangge realized that the ocean of music was boundless, deep and complex, and he might not be able to explore the whole picture after exhausting his life's energy, but he was willing to work hard to try.

In the two math classes, Qin Fangge thought more about music, judging from the results of the current exam test, it would never be a problem for him to get 400 points in the college entrance examination.

As a result, when he was in class, he had more time to wander around the world, let his mind run wild, and soar freely in the world of music. Even if he can't use a musical instrument at hand, it's okay for him. Musicians seem to be super talented, and they don't need to play or sing on an instrument, they already have a score in their heads. As if in the bottom of their hearts, they can get close to the concord with those beating notes, and direct them in a perfect and orderly combination.

When Qin Fangge thought about this, he drew them casually, and they were all musical symbols. Fortunately, as long as he doesn't mess with the classroom and affect the teaching, the teacher will not care about him, which can be regarded as giving him full freedom.

After class, Qin Fangge couldn't go to the cafeteria to grab food, because the squad leader Su Linru stopped him.

I feel that Su Lin is still such a cute girl when she doesn't keep a straight face, she will have a smile on her face, and she praised Qin Fangge for doing a good job today, and it was in vain that she played so many ambushes for him in front.

Qin Fangge attributed all the credit to her.

But Su Linru didn't appreciate it, and said solemnly, "I have always been a person who has always distinguished right from wrong, and you have the greatest credit, which cannot be denied." ”

Qin Fangge smiled, "Your credit is not small, if you didn't bravely enter the office and start the radio, the teachers wouldn't be able to hear it!"

"I don't have a hippie smile with you. Su Linru saw that he was spreading on the desktop paper and drawing messy notes, and his face was sunny and cloudy, "You should listen to the teacher's lecture in class! It's always right to learn more." Teacher Yuan just praised you, so you are proud!"

Qin Fangge replied, "I'm not proud, but I'm very satisfied with passing the exam, anyway, we don't need such a high score to learn art." ”

"That's not an attitude, I think your talent is very good and has a lot of potential, if you work harder, you will definitely be able to achieve better results in cultural classes. Su Linru didn't want to say anything about his unmotivated thoughts, but she still had to do her duty as a squad leader.

Qin Fangge is not ashamed, "I think if my talent and potential are used in music, I can achieve better results." ”

Su Linru opened his eyes wide, looked at him, and argued, "That can't be patronized by music and separated from the accumulation of knowledge in other aspects." Otherwise, it will be like a rootless ping, with no form. ”

Her eyes were very bright, her eyes were very shining, and her gaze was very hot, Qin Fangge was defeated in the eye with her, as if after thinking for a while, she slowly admitted, "You're right, I really shouldn't be so eager for quick success." ”

Su Linru's eyebrows fluttered like a triumphant returning general, and a smile bloomed on his delicate melon seed face, "That's right! And in addition to music learning, there should be many things in life, such as friendship and family affection, which are worth cherishing." ”

Qin Fangge nodded, "The class leader's understanding of life is also much deeper than mine, admire!"

Su Linru immediately became unhappy again, "Could it be that in your hearts, am I such a serious person who doesn't understand life?"

"How can there be!" Qin Fangge hurriedly denied it, "I have always felt that a responsible squad leader like you knows life the best." ”

Su Linru pouted and obviously didn't believe it, but she didn't say much, only said, "You must want to go to dinner early now! Go! I won't delay your time, just remember to listen carefully to the teacher's lectures during class time in the future, don't you still have time to study music in the evening?"

Qin Fangge could only nod and say yes, and said, "I know that the squad leader is the most empathetic, and I will pay attention to it in the future." Aren't you going to eat?"

Su Linru only smiled, "You go first, there are many people now, I'll go later!"

Qin Fangge asked, "You don't want to go on a diet and skip lunch, you still have to pay attention to nutrition." ”

Su Linru got angry, "Do you think I look like someone who needs to lose weight?"

Qin Fangge smiled, "I think girls want to be more beautiful, even if they have a good figure like you." ”

Su Linru was still quite confident in her figure, and his compliments only made her roll of the eyes, "Don't think that I will believe you in this way." ”

Qin Fangge didn't say much, took the guitar, and prepared to leave for the cafeteria, at noon Ning Xiupei was busy with the students and didn't have time to cook for them.

Su Linru asked him again, "Do you still bring a guitar with you to dinner?"

Qin Fangge explained, "It's not good to put the guitar at home and put it in the classroom when you go home after eating. ”

"Oh, then you go!" Su Linru waved angrily to drive people away.

Although Qin Fangge was not hungry to that extent, he still chose to go out of the classroom, eat a good meal early, and play the piano more when he got home. He had a new understanding today, and hurried home to test it.

He walked quite fast when he rushed to the cafeteria, but when he got downstairs, he was too fast to run, because several girls stopped him head-on. He was tall and carried a guitar on his back, and his goal was so obvious that he couldn't see them trying to dodge, so he had to go up hard.

is still the girl from the dance team, and the leader is still the bold short-haired girl, named Xu Tingting, who was pushed out by them last time to confess to him, Jiang Siyuan is also among them.

As soon as Qin Fangge saw this scene, he immediately decided to turn passivity into initiative and grasp the right to speak, so he asked them, "Aren't you going home this weekend?"

Xu Tingting said with a smile, "If we go home, we will definitely miss today's good show again." Senior Qin's two songs are well written and sung even better today, we all like them very much, and Yuanyuan is even happier, saying that she didn't wait so long in school in vain. ”

Jiang Siyuan blushed suddenly, and explained in a low voice, "Don't listen to her nonsense, our dance team is rehearsing the program today......

Xu Tingting continued, "We want to ask Senior Qin for help and guidance, knowing that the senior is busy, we don't dare to delay too much time, so we have lunch for a while." For our Yuanyuan's sake, senior, let's give face!"

Qin Fangge hurriedly replied, "It's okay if you want me to play music, if you dance too professionally, where can you use me as a layman to talk nonsense." ”

"No, I know that Senior Qin plays the piano well, plays the guitar well, sings well, dances well, and dances well, the martial arts exercises we used to do between classes, aren't the seniors involved in the design and the final dancers?" Xu Tingting knew him very well.

Qin Fangge laughed, "You guys are not kind, people are difficult to dismantle!"

Jiang Siyuan hurriedly said, "We think that martial arts exercises are very good, and we can learn some martial arts by exercising." It's much, much better than the bunny dance we have to do during recess. ”

Qin Fangge said, "Then I want to see ......"

Jiang Siyuan said with a smile, "It's better not to do it, just a few actions over and over again, everyone doesn't want to learn!"

She will be lively, "It's not good to stand and talk, senior, let's go to the cafeteria together, today is Xiaofeng's birthday, and I said that I would treat you to a small stir-fry." She also admires the seniors, please we must invite the seniors, they have already ordered food over there and waited for the seniors to pass......"

Qin Fangge shirked and said, "No, if I want to go, I will have to eat you poor." ”

Jiang Siyuan's smile was really good-looking, and she also had a coquettish tone, "We all know the amount of food that seniors eat, definitely not, anyway, we are all going to eat, let's go!"

"I suddenly remembered that I still have something to do!" Qin Fangge still wanted to struggle.

"I have to eat if I have something!" Xu Tingting and Jiang Siyuan didn't believe him, they were afraid that he would regret and run away, so they hurriedly dragged his arm left and right, and there were several girls behind him blocking his back road, so that he couldn't escape if he wanted to.
