I don't know when, Gu Xiaobai was already facing the audience and sitting on the side of the stage.

In front of him, there is a table, like an upright piano, but it is two circles larger than the upright piano, and the position of the keys is a round short stick, which has been streamlined and ergonomically processed.

The top of the "upright piano", with its myriad of cables, is attached to the shelf above the stage.

Gu Xiaobai's hands were empty, and he gently knocked down a piano key in front of him.

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

A Yong bell, which was one and a half meters long, firmly fixed to the bracket, and almost completely unable to shake, was suddenly struck.

With a "bang", the extremely rich and mellow C4 pitch sounded.

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

What a timbre! It's beautiful!

Is this the tone of the chime?

Yes, this is the tone of the chime.

But it doesn't sound exactly the same as a traditional chime.

Traditional chimes, including the Zeng Hou Yi chime, due to the limitation of size, when striking the upper row of bells with a relatively high tone and a relatively small bell, there will be some discordant, such as the unpleasant vibration sound of breaking the iron plate.

After all, the vibration of the shell is much more complicated than the vibration of the string, and its harmonics are too much, and it is difficult to have perfect harmony with its own overtones like the vibration of the string.

How to make a good sound is Gu Xiaobai's biggest challenge in creating the "Bell and Drum Piano" this time.

After Gu Xiaobai tried a lot of methods, he finally decided to increase it!

Increase the size of the bell body to enhance its volume, but also to enhance the stability of the sound, and then thicken the bell wall to adjust the pitch. 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 upper limit of the technology of the Spring and Autumn Period, and Gu Xiaobai even brought many Ming Dynasty technologies to the Spring and Autumn Period.

I'm going to mess around! Anyway, there's Qin Shi Huang behind me!

Burning books and pit Confucianism, pit burning wave after wave, no record will be left, perfect!

In the pre-Qin era, it was so capricious.

But the effect is perfect.

At this moment, the timbre of this chime is actually close to that of a round bell, and only after the attenuation of the fundamental tone and a few major harmonics can the dissonance of a small tail be heard.

This dissonance, however, is no longer a flaw, but a characteristic, a part of its timbre, representing its identity, a chime, not a round bell.

The sound of the round clock decays so fast, it can't be so fast!

And this is also Gu Xiaobai's consistent attitude, inheritance, but never conformist.

The bell and drum qin he wants to make is the pinnacle of traditional Chinese bells and drums, but they are definitely not a clumsy replica of the bells and drums of thousands of years ago, they are developed, they can keep up with modern aesthetics, and even lead the trend!

The area near the "carillon" in front is reserved for Kyoto University, the defense professors, and various review experts.

The two salted fish teachers are also sitting here at this moment, beside them, there are many peers engaged in acoustics, although everyone is a competitor this time, but after all, this discipline is very small, and they participate in various meetings on weekdays, and they are already familiar with it.

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

"How is that possible?

"Fake!"

"Is it a synthesized sound from a megaphone?"

"Listen closely, the clock is vibrating!"

Laymen listen to the excitement, insiders listen to the doorway, although the vast majority of people in the world do not have an absolute sense of sound, not to mention that a pervert like Gu Xiaobai can be accurate to 1 decimal place. But the human ear is instinctive to distinguish between "harmony and non-harmony". A sound that is enough to be heard in the first moment it enters the ear.

For ordinary people, this harmonious and pleasant sound just makes people feel good in the ear, but for those who are engaged in acoustics, countless contents are instantly thought of.

Yes, as they have emphasized to countless people before, the mechanical design of this "Bell and Drum Piano" is not difficult, and it is not difficult to process and manufacture, as long as there is money!

What's hard?

The hard part is tuning!

The human ear is sometimes so dull that it is impossible to distinguish between the high and low tones.

But sometimes it's so keen that it can tell the difference between good and bad tones better than any other instrument.

You know it when you hear it!

It's so obvious!

Behind the side of the sitting area, Duan Guixin stood up with a bang.

What's the situation?

This tuning?

Gu Xiaobai, he's done?

"Impossible...... No way, it's just a bell......"

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

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

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

The bell is not like a piano, it can be adjusted by tightening or loosening the strings, it must be done in one step!

Gu Xiaobai: How long has it been since he designed this bell and drum harp? Can't all the bells be in place in one step, like this level of perfect tuning, I'm afraid it will take dozens of casts to pick out one that can be used?

Impossible, impossible......

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

As soon as you play one more note, you're exposed.

But Gu Xiaobai didn't continue to play.

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

The pitch of this bell is C4, which is almost the center of the range of the bell and drum, and its position is also the center of the entire shelf, at the moment when the bell is ringed, the bell body suddenly lights up, and then the light changes, and the ripple-like thing in a circle spreads in all directions, and transmits to other bells nearby, all the bells light up in turn, and the slight resonance makes all the bells on the entire bracket ring gently, and the light is 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 of the whole body, and the same is true of the "Bell and Drum Piano".

The peculiar acoustic effect amplifies the volume of this Yong clock, spreading in all directions.

And the light did not stop directly, but after leaving the bell, it spread to all directions of the entire stadium, obviously the lighting effect of the bell body, related to the lighting and dance of the audience, and the glow sticks held by the audience were also lit up at the same time.

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

Listening to the gentle bell ringing in my ears, and looking at the lighting effects that reverberated back and forth throughout the audience, at that moment, the audience had goosebumps and hair stood up.

I'll go!

Lao Tzu is going to blow up!

This is the Lyre of Bells and Drums?

Great!

When the bell disappeared, the lights converged in the middle from all directions, until the bell in the center of the shelf dimmed, and the whole audience fell into darkness again.

There was silence for three seconds, and then a crazy cheer resounded in the sky: "Whoa, whoa!"

This is Gu Xiaobai, as long as one action and one sound, he can make the audience crazy!

Gu Xiaobai smiled slightly, and seemed to be very satisfied with everyone's reaction under the stage, and in the next second, he opened his hands and pressed them at the same time!
