"Woo-woo-mile ↗ ↗ ↗ ↗-......" gradually went up, and the faster and faster sound of the spitting flute echoed in the workshop.

The black-faced, short Qin Chuan, wearing blue overalls and a hard hat, stood in the middle of various machine tools without the slightest decoration, and put a flute without the slightest decoration in front of him, after dozens of fast notes in a row, and then suddenly his arm trembled, and his body shook together, and the rapid spitting sound turned into a trembling sound that rose up and gradually fell.

Qin Chuan originally hoped that Gu Xiaobai would try out the sound in person, but seeing that Gu Xiaobai couldn't play the flute at all, he couldn't even blow the sound, so he could only come by himself.

Gu Xiaobai's eyes sparkled when he heard it, on the one hand, he saw that the flute made with his own formula could make such a beautiful sound, and on the other hand, he heard such beautiful music.

Next to her, Senior Sister Jing looked at Qin Chuan's eyes, and her tenderness seemed to be about to melt.

This man who is not tall, handsome or white, is the man he likes, and he may have to go with him for the rest of his life.

"Ah, I've heard this song before!"

"Lao Qin used this song to chase Sister Jing into his hands. ”

"I still remember Valentine's Day, there were people playing guitars, singing love songs, candles, and flowers downstairs in the girls' dormitory......

Qin Chuan listened, happy in his heart.

No matter how handsome Xiaobai is, he can't play the flute, I still have a hand in Qin!

"What's the matter, it's because the flute is loud and can't stop it when the window is closed, so I came down......" Senior Sister Jing was shy, but when she looked at her man, she was also happy.

The hooligans in folk music, suona is the boss, if the flute claims to be the third, I'm afraid no one dares to call himself the second.

This kind of musical instrument with opera bangzi, performed in a large court and crowded place, if the sound is not loud, it would have been eliminated long ago.

Gu Xiaobai felt that he had learned, and said with wide eyes: "If I chase girls in the future, will I also play the flute?"

Senior Sister Jing shook her head and said, "No, Xiaobai, you remember, if you meet a girl you like, just stand there and smile at her, only ugly people like my family Qin Chuan need to play the flute." ”

"Oh......" Gu Xiaobai showed a well-behaved smile, stared ahead, and wrote it down in his memory palace.

Qin Chuan: "......"

Forget it, don't blow it!

Irritating!

He looked down at the flute in his hand and said, "What a flute...... It's a little better than the famous flute I bought. ”

Is such a flute really made by yourself?

Although they can process all kinds of complex parts, and in the future, they will also process all kinds of precision devices with high precision to the point of explosion, compared to that, a flute is nothing, but now, Qin Chuan still has an inexplicable sense of achievement.

"These few drills are worth a thousand yuan. ”

As soon as these words came out, Qin Chuan's heart suddenly moved, and he thought of something.

He looked up at Gu Xiaobai and wanted to speak, but he couldn't.

Next to him, Sister Jing hit him: "Your hole is worth 5 cents, haven't you heard the story of that German expert......

"I know, I know, it's not worth drawing a line, it's worth knowing where to draw a line, right......" Qin Chuan was hit by his mother-in-law, so he thought more, and he handed the flute to Gu Xiaobai with both hands: "Thank you." ”

Gu Xiaobai blinked, you helped me make a flute, what are you thanking me for?

A message popped up on the phone: "The bamboo flute production is completed, please ask the host to passively train the beginner bamboo flute playing skills as soon as possible." ”

Qin Chuan cautiously pointed to the other flutes: "Let's continue?"

"Go on. ”

"Okay!" Qin Chuan was nervous and excited, rubbing his hands, "Your formula, can I calculate it myself?"

After getting Gu Xiaobai's approval, he took out another D-tone material, carefully leveled the inner chamber, measured the inner diameter, and then took a pen and paper to calculate the formula and distance beside him.

The formula summed up by Gu Xiaobai is not difficult at all for science students in the university, Qin Chuan substituted the frequency and diameter respectively, calculated the distance, and then began to drill.

A few onlookers on the side, looking at the hot eyes, also came over and asked Gu Xiaobai for a flute, calculating and experimenting at the same time.

Gu Xiaobai ran back and forth, helping them calculate the numbers and check the answers, and for a while, the entire internship workshop was as if they were conducting an experimental class guided by Gu Xiaobai.

It is as if Gu Xiaobai is the boss of a black factory that processes flutes, and he is exploiting cheap labor.

But Qin Chuan is the most stable and fastest, and it is also the most accurate pitch.

Qin Chuan finished making another flute, skillfully pasted the flute membrane, and tried to blow it, feeling that this one seemed to be better, he turned his head and wanted to call Gu Xiaobai to come over to try the flute, Sister Jing sighed and said, "Xiaobai seems to be asleep." ”

"It is said that I got up early in the morning to look for the flute. ”

"Don't disturb him, let him sleep. ”

A few girls whispered.

Qin Chuan turned his head and helped other flutes to paste the flute film first.

This pile of flutes, I'm afraid there are not twenty or thirty, from A to G, three sets can be selected.

After pasting a few flute membranes, Qin Chuan heard a sound of "spitting and spitting" behind him.

I saw that Gu Xiaobai had woken up, wearing headphones, looking at his mobile phone, and spitting on the flute.

"Xiaobai's classmate is so good-looking even to spit. A few girls held their faces.

Qin Chuan couldn't cry or laugh, neither was he jealous, nor was he jealous, and said, "Xiaobai is learning to play the flute." ”

Gu Xiaobai tried a few times, and suddenly blew out a long note: "Woo......"

Gu Xiaobai blows the barrel sound of this flute, that is, the sound of the six fingers pressed, and the flute in C key, which is the G below the central C, that is, G3.

The overall vocal range of the flute is on the high side, because as I said before, according to the laws of physics, the lower the flute, the greater the breath required, and the flute is a blow-hole type, not a mouthpiece type, and it will blow to the lack of oxygen.

After blowing this sound, Gu Xiaobai's eyes lit up, and the effect of passive training just now slowly showed itself.

Passive training, training is reflexes and instincts, Gu Xiaobai's current feeling is like a person who used to play the flute, but hasn't played it for a long time, many things the brain may not remember, but the body still remembers.

When he handed over the control of his limbs from his brain to the reflexes of his limbs, and relaxed his whole body, he immediately felt that something was different.

"Sol-la-si-do-re-" A complete flat blowing scale was blown down, Gu Xiaobai felt that his limbs were becoming more and more flexible, more and more relaxed, and the more relaxed, the more flexible, he climbed the scale seven or eight times in a row, from the beginning of the stumbling, to the smooth.
