Chapter 464 Shocking Zhongle
At some point, Gu Xiaobai was already sitting on the side of the stage facing the audience.

In front of him, there is a table, which looks like an upright piano, but it is two circles larger than the upright piano. The positions of the keys are round short sticks, which have been streamlined and ergonomically processed.

The top of the "upright piano", a myriad of cables, connects to a shelf above the stage.

Gu Xiaobai clasped both hands, and tapped lightly on a piano key in front of him.

At that moment, the round rod-shaped key pulled the cable behind it. The cable passed through four or five pulleys, pulled a wooden heavy hammer, and fell down suddenly.

A 1.5-meter-long bell that was firmly fixed on the bracket and could hardly shake was rang suddenly.

With a sound of "dong", the extremely thick and mellow C4 pitch rang out.

The mellow bell body resonance, coupled with the complex and mellow overall resonance, the moment the timbre sounded, the audience present already screamed "Wow".

What a tone!What a nice view!

Is this the sound of a chime?
Yes, this is the chime tone.

But it is not exactly the same as the traditional chime tone.

Traditional chime bells, including Zenghouyi chime bells, due to the limitation of volume, there will be some disharmony when striking the upper bell with relatively high pitch and relatively small bell body, like the kind of broken iron pieces Unpleasant vibrating sound.

After all, the vibration of the shell is much more complicated than the vibration of the string. It has too many harmonics, and it is difficult to achieve perfect harmony of its own overtones like the vibration of the string.

How to make a good sound is the biggest challenge for Gu Xiaobai to build the "Qin of Bells and Drums" this time.

After Gu Xiaobai tried many methods, he finally decided to increase the size!Make it bigger!

Increase the size of the bell body to enhance its volume, but also to enhance the stability of the sound, and then adjust the pitch by thickening the bell wall.At the same time, through complex tuning technology, the fluctuation of the bell body is adjusted to the most harmonious state.

This kind of processing technology and difficulty has almost reached the technical upper limit of the Spring and Autumn Period. Gu Xiaobai even brought many technologies from the Ming Dynasty to the Spring and Autumn Period.

I'm going to fuck fuck fuck fuck!Anyway, there is Qin Shihuang behind him!
Burning books and burying Confucianism, one after another, no records will be left, perfect!
In the pre-Qin period, it was so capricious.

But it works perfectly.

At this moment, the sound of the chime bell is actually close to that of a round bell. Only after the fundamental tone and several major harmonics have decayed can the dissonant sound like a dragging little tail be heard.

This kind of disharmony is no longer a flaw, but a feature, a part of its timbre, and represents its identity. It is a chime bell, not a round bell.

The sound decay speed of the round clock cannot be so fast!
And this is also Gu Xiaobai's consistent attitude, inherited, but never sticking to it.

The qin of bells and drums he is going to do is the pinnacle of traditional Chinese bells and drums, but they are definitely not clumsy replicas of bells and drums thousands of years ago, they are developed, they can keep up with modern aesthetics, and even Can lead the trend!
The area near the "carillon" in the front is reserved exclusively for Peking University, defense professors, and various review experts.

Two salted fish teachers are also sitting here at this moment. Beside them are many colleagues who are engaged in acoustics. Although everyone is considered a competitor this time, this subject is small after all. They attend various meetings on weekdays, but they do not look up. See, already familiar with it.

The moment the perfect bell rang, he heard a series of exclamations from around him.

"How is it possible? What's the situation?"

"really!"

"Is it the synthesized sound from a loudspeaker?"

"Listen carefully, the clock is shaking!"

Laymen listen to the excitement, and experts listen to the way. Although most people in this world do not have absolute pitch, let alone someone as perverted as Gu Xiaobai who can be accurate to one decimal place.But the human ear, to distinguish "harmonious or not", is an instinct.A sound, the moment it hits the ear is enough to hear it.

For ordinary people, this harmonious and pleasing sound is just pleasant to the ear, but for those who are engaged in acoustics, they think of countless things in an instant.

Yes, as they have emphasized to countless people before, the mechanical design of this "Qin of Bells and Drums" is not difficult, and the processing and manufacturing are not difficult, as long as you have money!
What is difficult?
The hard part is tuning!
People's ears are sometimes so dull that they can't distinguish the high and low of two tones.

But it is sometimes so sensitive that it can distinguish good or bad timbres better than any other instrument.

Know it by ear!
It's so obvious!
Behind the sitting area, Duan Guixin stood up with a bang.

what's the situation?
This tuning?

Gu Xiaobai finished?
"Impossible...impossible, it's just a clock..."

It is not difficult to tune a bell, but it is difficult to tune the 57 copper bells on the entire shelf, and more than half of them are tuned by one bell and two tones!

Even if this tune is perfect, there are still 56 bells left!

The timbre of each bell is perfect, but the key is that all the bells must be in tune and in tune!

The clock is not like a piano, you can adjust it by tightening or loosening the strings, it must be in place in one step!
How long has it been since Gu Xiaobai designed this qin of bells and drums?Not all the clocks can be in place in one step. For such a perfect tuning, I am afraid that dozens of clocks must be cast to pick out a usable one?

Impossible, impossible...

Duan Guixin decided to wait, you can't just play this one note.

As long as you play the next note, you will be exposed.

But Gu Xiaobai did not continue to play.

After pressing the note, he turned around and looked down the stage.

The pitch of this Yong bell is C4, which is almost the center of the range of the bell, drum, and qin, and its position is exactly the center of the whole shelf. The light changes, and circles of ripple-like things spread in all directions and spread to other nearby clocks. All the clocks light up in turn, and the slight resonance makes all the clocks on the entire bracket ring softly, and the light also flickering slightly.

Just as the timbre of a piano is never the resonance of a certain string, its beautiful timbre comes from the resonance of all the strings in the entire body, and the same is true for "The Qin of Bells and Drums".

The peculiar acoustic effect magnified the volume of the Yongzhong and spread it in all directions.

And the light did not stop directly, but spread to all directions of the entire stadium after leaving the bell body. Obviously, the special lighting effects of the bell body are related to the lighting and dance beauty of the audience, and the light sticks held in the hands of the audience present , also lights up at the same time.

Circles of sound wave ripples spread in all directions, spread to the entire stadium within a second, passed to the edge of the stadium, and then reflected back, forming complex interference fringes.

Listening to the slight ringing of the bell echoing in the ears, and seeing the lighting effect that was stirring back and forth in the audience, at that moment, all the audience in the audience had goosebumps and their hair stood on end.

I go!

I'm going to blow it up!
Is this the zither of bells and drums?
Great!

When the bell disappeared, the lights were drawn from all directions to the center, until the Yongzhong in the center of the shelf was darkened, and the whole venue was once again plunged into darkness.

There was silence for three seconds, and then wild cheers echoed through the sky: "Aoooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!"

This is Gu Xiaobai, with just one movement and one voice, he can drive the audience crazy!
Gu Xiaobai smiled slightly, and seemed satisfied with everyone's reaction off the stage. In the next second, he opened his hands and pressed them at the same time!
　Uncle Ha counted, someone would complain about Uncle Ha's ringing of the bell and write a chapter.

　　Please be cautious about complaining, believe it or not, Uncle Ha can write another chapter...
