On stage, the four of them didn't have any stage movements, no cool dances, and no too many expressions.

One stands, three sit, no instruments, no accompaniment, only mournful whistles and muffled chanting.

Offstage, the judges listened quietly.

What is it?

A Cappella (a cappella)?

Perhaps, but is the whistle an accompaniment or a vocal?

Is it a musical instrument, or is it singing?

Is it accompanied, or unaccompanied?

Is a table a musical instrument, and what's the difference between slapping a table and slapping a belly?

And the lyrics of this song are exceptionally simple.

Without Bai Mo's usual aggressiveness and sharp words.

I don't have that high spirit, and I don't want to move forward.

At this moment, the four people on the stage are the four lonely and melancholy teenagers on the eve of the college entrance examination, watching the countdown coming day by day.

Who is the "you" in their mouths?

What do "you" look like?

I don't know, I don't know anything.

But because I don't know, I have enough room for imagination, and everyone can't help but think of his own him and her.

I remembered my high school years.

On the stage, Gu Xiaobai was still singing:

"One hundred days, one hundred days......

A hundred test papers were folded into geese

One hundred days and one hundred days......

A hundred pieces of chalk are gone

One hundred days and one hundred days......

One hundred days and one hundred days......

The last 100 days before separation

One hundred days and one hundred days......

One hundred days and one hundred days......

Why are all 100 days over?

We'll never see each other again tomorrow......"

This song condenses all the imagery to the extreme.

There are only four images left in the whole song.

You, the test papers, the blackboard, a hundred days.

It didn't have a chorus or a climax, and it just kept singing.

Yes, life in high school is like that, especially when the college entrance examination is approaching.

All that is left is the classroom, learning, boring and boring.

No impulse, no passion.

There is only loneliness.

The lyrics are repetitive, but the beautiful melody and the subtle changes brought about by Gu Xiaobai's excellent singing skills make this song not boring at all.

In the audience, a judge listened and listened, and when he heard the last sentence, his eyes suddenly turned red.

It turns out that I thought there were still a hundred days, but it was just a fleeting moment?

Suddenly, tomorrow a hundred days will be over?

What should I do?

Do you want to confess and apologize?

Or are you still waiting silently for this last day to pass?

After singing "I'll never see each other again tomorrow", Gu Xiaobai suddenly raised his head.

A third whistle joins in.

Hey, wait, it's not a whistle!

Gu Xiaobai didn't whistle, but opened his mouth.

Whistle!

Bass whistle!

The raging air currents slammed into his vocal voice, vibrating the walls of the pipe and making a whistle-like sound.

But the whistle is too low.

In the audience, the judges froze.

Wait, is this a showmanship?

Most of the people present had heard Gu Xiaobai's high-pitched whistle.

In the chanting version of "Yanyan", the high-pitched whistle as high as C8 cleanses people's hearts.

And now, Gu Xiaobai's whistle is hovering up and down in highC, that is, C5.

Can the whistle sound be as high as C8 and as low as C5?

Even the whistle can span three octaves? Is this human?

This sudden show off is too ...... Uh, perverted.

"Actually, Xiaobai can't whistle......" Next to Fu Han, he ruthlessly betrayed Gu Xiaobai's weakness.

What? Can't whistle?

You say that even the whistle can span three octaves, and a young man who plays all kinds of wind instruments can't whistle?

That's really ...... emmmmm......

This world is truly mysterious.

But soon, their shock at Gu Xiaobai's "indiscriminate filling" whistle disappeared.

Wait, what is this?

Gu Xiaobai, Wang Haixia, and Zhou Xianting whistled and formed a three-voice part.

Gu Xiaobai's whistle is in these three parts, acting as the middle frequency.

Wang Haixia is a lip blowing method, at this time controlling the speed and the position of the tongue, blowing a relatively low and thick tune.

Zhou Xianting is tongue blowing, he bared his teeth, and the frequency was slightly higher, and there was some breath sound.

The three of them form three voices, and the three melodies are different, but they are all so melancholy, lonely, and blended together, but so good!

Is this polyphony?

I'm going, are all the kids now starting to play with such advanced ones?

And the tune is so well written!

Polyphony is actually quite common, such as canon.

Canon is strictly repeated with each other, entering at different times, imitating each other.

But at this time, the three people, the three tunes are different, but they are all very sad.

There are not many imitations, they develop separately, but they also have the same melody, occasionally coincide, and then separate again.

It's like an accidental passage after class, or a chance encounter in the hallway.

Offstage, the eyes of many professionals widened.

It's not a canon, it's a fugue.

Using strict counterpoint, the voices are arranged into harmonious chords, and the melody of each melodic line is also considered.

This is more difficult than the way of setting chords, and it is heavenly.

Three times as sad, nine times as lonely, and N times as difficult!

Senior!

So, the song, it sounds like a ballad, it looks like a cappella, is it actually classical at the core?

I'll go, good high, good high!

Such simple lyrics, with such a simple-sounding, actually very advanced, complex melody, today's children, really good at playing!

Ordinary fans, at this time, I just feel so sad to listen to!

If someone whistles in front of me like this, I will immediately pounce on me and confess.

Where will wait until 100 days later, tomorrow will be separated!

It doesn't matter if you're beautiful or ugly, it's you.

But professional fans have been shocked.

At this moment, Zhao Mo also joined in.

His way of whistling is intermittent, and he can only sound a single scale at a certain time.

It's like having a clumsy child repeating the scales of the main melody at an inopportune time.

But his addition instantly made the whole song more harmonious and beautiful.

I go, it turns out not a whistling trio, but a quartet!

Difficulty: Max!

Nowadays, the children have studied music theory so deeply?

Is this something that should appear in an original competition for non-classical music composition?

At this moment, the judges did not know whether to be shocked by the melody, or the form, or the music theory knowledge it displayed.

In fact, they all overthink it.

In fact, the process of writing the melody of this song is like this.

"Little man, the mid-frequency overtones of your whistle are relatively concave, and the high-frequency overtones are too prominent, you have a semitone down this scale, and use eight overtones to make up for Brother Ting's six overtones...... Yes, it's much more harmonious. ”

"Zhao Mo, you join in at this time, cover up the glitch of Xiao Xiazi's high-frequency overtones, and suppress his seven overtones, yes, this is the sound ......"

In fact, when this song was written, it was not romantic at all.

But at this moment, looking at the four people on the stage whistling, everyone felt.

If, loneliness will sing.

Then it must be singing such a song.
