Percussion is probably the oldest and most rooted music in the world.

Two fists, striking the chest, can deter the enemy.

Two drumsticks, beating up and down, can inspire the three armies.

Two heels, stepping on the ground, can make people sway along.

From an acoustic point of view, music is composed of sound and noise.

Musical sound is a periodic vibration, the continuous input or slow attenuation of energy, resulting in a periodic sine wave, or a periodic wave composed of the superposition of the sine wave and its own harmonics, such as the vibration caused by the continuous input of the string vibration and the wind music, are all musical sounds.

This kind of musical sound can produce a very clear and definite sense of pitch in the human ear, can clearly locate its pitch, and can form a melody.

However, most percussion is strictly "noise", and its fluctuations are not cyclical, but decay at an extremely fast rate.

For example, gongs and drums.

"Bang~~"

"Boom-"

Due to the lack of sufficient temporal information, the pitch perception is relatively insignificant, although there is still pitch.

But this kind of sound, to the human ear, will be noisy.

So it's noise.

Of course, the human ear does not distinguish between "music" and "noise", and even "noise" can be continuously output in some way to produce continuous periodic sounds.

It's like shaking the fingers in the zither or the wheel fingers in the pipa.

Or...... Drum rolling.

Gather the dots into a line, turn noise into fun.

That's where percussion really comes in.

A drumbeat was piercing and unpleasant, and when it was fast......

Everything has changed.

At quarter notes, the percussion is like a poor kid humming on the side of the road that no one wants.

When it comes to eighth notes, percussion is a bit like shouting microphones, which can be tricked into rewarding.

At sixteenth notes, percussion can be used as a hiphop beat, and when it comes to thirty-second notes or even sixty-fourth notes......

The time has come to witness the birth of a miracle.

You find that your drum, its expressiveness, is no weaker than any melodic instrument.

And when your hands are fast and the time is terrifying......

That's probably what it is now.

"Is that Teacher Xiaobai?" When Gu Xiaobai's rolling music sounded, the black bear spirit seemed to see Ultraman's transformation, and his eyes bulged out.

Rolling is probably the fastest way to play percussion.

Throw off the drum stick, then borrow the power of the drum surface to bounce, and then use the power of your fingers to continue to press down, and the time you knock it out can actually bounce several times.

At this time, the black bear spirit drummer pricked up his ears to carefully distinguish the sound coming from the monitor speakers, and wanted to hear clearly how many times Gu Xiaobai played every roll.

Four times? Wrong...... Five times!

Gu Xiaobai rolls with sixteenth notes, and every time the drum stick is struck, it will be played five more times, and it will sound six times, which is absolutely the strength of a professional-level drummer!

The black bear drummer is a bit of a hit......

How could it be, Teacher Xiaobai is better than me in playing the drums!

Stumble!

Have I practiced all the hard work of (touching) (fishing) for ten years to practice on dogs?

And the timing of Gu Xiaobai's every sound is accurate and terrifying, as if there is a metronome in Gu Xiaobai's body that is extremely accurate.

The black bear spirit wanted to know how Gu Xiaobai practiced this basic skill.

How can someone be able to control even such tiny muscles and form muscle memory!

This way of playing feels particularly strange.

Obviously, the two drum sticks were knocked down alternately, and the sound produced was six times the number of strikes. One person, two hands, two drum sticks, but it is like a rainstorm falling on the lotus leaf field, like the footsteps of tens of millions of people in the welcoming team, like tens of thousands of firecrackers sounding in the distance at the same time.

The lively atmosphere suddenly came up.

After rolling two bars, Gu Xiaobai "snapped" and closed the sound.

Then next to it, the guitar of the letter sounded.

Fu Han is also a versatile musician who knows a variety of instruments, but his favorite is the guitar.

After Gu Xiaobai's bass drum rolling, he held the guitar, smiled slightly, and heard a few "Zheng Zheng" sounds in the monitor speaker, which came out.

"Huh?" Outside, Fu Wenyao listened to the sound coming from the monitor speaker, and his eyes were about to pop out.

No, this is not the sound of a guitar~ This is a pipa!

At this moment, Fu Wenyao had a sense of confusion.

He fell on his stomach on the glass window.

Brother, did you get the wrong instrument?

Brother, please put that pipa upright!

Wrong...... Brother, please let go of that guitar, that's not the sound of a guitar!

Brother, if you really can't afford to buy a pipa, I can go buy you one, please give me your limited edition guitar!

But no matter how he wailed outside, the whole person had to stick to the glass window, and Fu Hanwu inside was unconscious, and after the sound of the "Zheng Zheng Zheng" pipa, Wu Zi resounded non-stop, and he not only added the main theme, but also added chords and ornaments.

This guitar, it not only disguises the lute, but also does the work of the whole band.

It's hard to believe that this is the sound that a six-string guitar can make.

Fingertips!

And it's a magical finger bullet technique.

No, the amazing fingerstyle technology, plus the amazing timbre control technology!

Change the playing position, suppress the unwanted overtones, change the timbre, let the guitar produce a more exciting timbre of the pipa, play to the point of interest, Fu Han stroked down with his left hand, "Zi'er~" sounded, like the sound of an electric guitar.

In the next second, Fu Han's fingers were released, and the sound of a guitar like water sounded.

Main themes, chords, rhythms, flowers, and boards!

Even Gu Xiaobai, the drummer, was robbed.

As we all know, the guitar is a percussion instrument!

At this time, one person is a band!

"I'll go, my brother is so powerful!" Fu Wenyao looked at Fu Han's finger shooting skills.

Playing the main theme, Fu Han smiled at Gu Xiaobai.

It's a bit provocative.

Look, Brother Han, I play my guitar well.

"Hmm......" Gu Xiaobai's eyelids drooped and looked at the drums in front of him.

Library system, start-up, Helmholtz equations, arithmetic!

In an instant, in Gu Xiaobai's mind, several drum surfaces of different sizes appeared, each of which was constantly vibrating.

His brain was running at an astonishing speed, revealing the complex waveforms that vibrated from each drum surface.

Compared to the sine wave of the chord vibration, the drum vibration is an order of magnitude more complex, and its waveform is like a kaleidoscope!

Gu Xiaobai's drum sticks always adjust their position on the drum surface, suppress the waveform, change the timbre, and form a legato with pitch and even intonation under the continuous rolling.

Outside, the black bear spirit dragged Fu Wenyao down from the window and pasted his big face on it.

"No, is it my delusion? Why do I think Mr. Xiaobai's drum can speak?"

"......Ahh

Wait, it's not talking, it's singing!

This is the lyrics of "Writing"!

Is this a drum?

Is this something that a drummer can do?

This is too mysterious!

At that moment, the black bear spirit drummer and Fu Wenyao, who were listening outside, suddenly had a ......

Wife, come out and see how God feels.
