After dreaming of getting rich, I dressed up as a collapsed idol

A boy from the School of Physics played a piece called "Hundred Birds Paying Homage to the Phoenix" on suona, which also attracted applause from the whole room.

Then, as the performances went on, somehow there were signs of differences between the departments.

They were all secretly competing to see which department had the best performance.

The Chinese Department has made a good start, but there has not been any outstanding performance so far.

"Looks like it's my turn."

Zeng Yiqing found a basketball from somewhere and was eager to try it out.

Lu Qingfeng opened his eyes and encouraged him a few words, but suddenly felt something was wrong.

On the girls' side, led by Zou Yanxi, their eyes frequently looked here and pointed at him without any concealment.

Finished!

He immediately guessed what the girls in the class were planning.

Sure enough, after a boy from the law school who sang and played the guitar came off the stage.

The Chinese Department became noisy.

"Lu Qingfeng, our Lu Qingfeng is going to perform a show."

Zeng Yiqing, who was about to go on stage, was stunned.

Lu Qingfeng shrugged helplessly at him. It was not that he wanted to pretend, but his strength did not allow it.

He brushed the weeds off his butt and stood up.

It was a little after eight o'clock in the evening, and there were only a few scattered stars in the city's night sky.

The searchlights around the playground were on, casting the space in warm light.

Lu Qingfeng took off his hat, and his long hair gently fell over his eyebrows.

The narrow and long fox eyes are smiling, and the beautiful facial features, etched by light and shadow, have the exquisite feeling of being carefully carved by an artist's chisel.

In this playground filled with the atmosphere of youth, the young boy is as eye-catching as the breeze and the bright moon.

After a brief moment of surprise, there were cheers and applause.

There were also some screams in between.

Many people know that this year a new freshman came to the Chinese Department who is good-looking, has outstanding creative ability, and can play the violin.

The two lines of poetry I wrote at the beginning of the school year were praised by the school leaders.

Among the freshmen enrolled this year, he is the most talked-about one.

We are all Peking University students, so we are usually a bit reserved.

But at this moment, perhaps the group atmosphere amplified everyone's emotions, and everyone was less restrained than usual.

Emotions are more outward

"Lu Qingfeng, come on."

Lu Qingfeng couldn't help laughing.

"Actually, I didn't come up prepared. I didn't bring my violin, and I haven't learned any other instruments yet. Everyone knows from my voice that I can't sing. I don't even know what to perform."

"It's okay, we'll go get you your violin."

It was Guo Hao shouting in the crowd.

Lu Qingfeng glared at him.

"Forget it, it takes too much time."

He glanced around and suddenly saw that the cup he used to drink sour plum soup during the day had not been taken away. He wondered if the old Taoist priest had forgotten about it.

"Brother Fei, Haozi, Lao Zhang, please help me get those glasses."

The three people in the dormitory naturally would not refuse and moved the basket of more than 40 glasses over.

He then asked the people at the scene for some mineral water.

Finally, find two resilient branches.

At first everyone was curious about what he was going to do, but when they saw him add water to the cup and then knock on the rim of the cup with a stick, they knew what he was going to do.

This is making instruments on the spot.

The principle of a water cup as a musical instrument is the same as many regular musical instruments, which is based on the principle of resonance.

When the cup is filled with water, the volume of the water resonates with the air, which can resonate and amplify the sound.

The tone of the sound will change depending on the type of water.

Because the pitch of a sound is determined by the frequency of the vibration of the sound source.

The higher the frequency, the higher the pitch; the lower the frequency, the lower the pitch.

Simply put, the more water you put in, the greater the total mass of the vibrating cup, and the lower the sound.

On the contrary, the higher it is.

In this way, by combining them according to different water levels to form different scales, a water cup piano is formed.

This instrument is very simple and any ordinary person can make sounds by tapping it. The only difficulty is accurately identifying the pitch of each cup.
