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

Knock your chest with two fists to intimidate the enemy.

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

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

From an acoustic point of view, music consists of sounds and noises.

Musical sound is periodic vibration, continuous input or slow attenuation of energy, resulting in periodic sine waves, or periodic waves composed of the superposition of sine waves and their own harmonics, such as the vibration of piano strings and the continuous input of wind instruments.

Vibrations are all musical sounds.

This kind of music can give people a very clear sense of pitch, and it can clearly locate its pitch and form a melody.

However, most percussion music is strictly speaking "noise". Its fluctuations are not periodic, but decay at an extremely fast speed.

For example, gongs and drums.

"Bang~~"

"Dong——"

Because it lacks sufficient time domain information, its pitch sense is relatively unobvious. Of course, there is still pitch.

But this kind of sound will be noisy to human ears.

So it is noise.

Of course, the distinction between "music" and "noise" by the human ear is not strict, and even "noise" can be continuously output in some way to produce continuous periodic music.

It's like the wagging finger in guzheng or the round finger in pipa.

Or...the rolling of a drum.

Gather points to form a line and turn noise into joy.

This is the real origin of percussion.

The sound of a drum is harsh and unpleasant, and when it gets faster...

Everything has changed.

When playing quarter notes, the percussion sounds like a poor kid humming on the side of the road that no one wants.

When playing eighth notes, the percussion is a bit like shouting, and you can get some rewards.

When it's sixteenth notes, percussion can be used as a hiphop beat, and when it's thirty-second notes or even sixty-fourth notes...

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

You find that your drum's expressive power is no weaker than any other melody instrument.

And when your hands are fast and your timing is terrifyingly accurate...

That's probably what it is now.

"That's Teacher Xiaobai?" When Gu Xiaobai's rolling music played, the black bear spirit's eyes bulged out as if he had seen Ultraman's transformation.

Rolling is probably the fastest way to play percussion.

Throw the drum stick down, then use the power of the drum head to bounce it up, and then use the power of your fingers to continue pressing down. In fact, it can bounce several times during the time it takes to hit it once.

At this time, the Black Bear Demon drummer strained his ears to carefully distinguish the sound coming from the monitor speakers, trying to hear clearly how many times Gu Xiaobai had played each roll.

Four times? No... five times!

Gu Xiaobai rolls with sixteenth notes. Every time the drum stick is struck, it will play five more times and ring six times. It is absolutely the strength of a professional drummer!

The black bear spirit drummer was a bit shocked...

How could it be possible? Teacher Xiaobai is better than me at playing the drums!

fall!

Have all my ten years of hard work (touching) and practicing (fishing) been transferred to dogs?

Moreover, the timing of each of Gu Xiaobai's sounds was terrifyingly precise, as if there was an extremely precise metronome inside Gu Xiaobai's body.

Black Bear Spirit wanted to know how Gu Xiaobai developed such basic skills.

How could someone possibly be able to control such a tiny muscle and form muscle memory!

This way of playing gives people a very strange feeling.

It is obviously two drum sticks hitting each other alternately, but the sound produced is six times the number of hits. One person, two hands, two drum sticks, but it is like a heavy rain falling on a lotus leaf field, like a wedding reception.

The footsteps of tens of thousands of people in the team were like tens of thousands of firecrackers going off in the distance at the same time.

The lively atmosphere suddenly arose.

After playing two bars, Gu Xiaobai made a "pop" sound and stopped playing.

Then next to him, the guitar playing for the letter started playing.

Fu Han is also a versatile musician and can play various instruments, but his favorite is the guitar.

After Gu Xiaobai's bass drum roll ended, he hugged the guitar and smiled slightly, and heard a few "clang" sounds from the monitor speakers.

"Huh?" Outside, Fu Wenyao's eyes almost popped out of his head as he listened to the sound coming from the monitor speakers.

No! This isn’t the sound of a guitar~ It’s a pipa!

At this moment, Fu Wenyao felt confused.

He leaned all over the glass window.

Brother, did you pick up the wrong instrument?

Brother, please put that pipa up! The pipa is played vertically!

No...please let go of that guitar, that's not the sound of a guitar!

Brother, if you really can’t afford a pipa, I can buy one for you. Please give me your limited edition guitar!

But no matter how he wails outside, his whole body will be pressed against the glass window, and the payment letter inside will be unknowingly followed by the "clanging" sound of the pipa, and he not only plays the main melody, but also plays the chords.

, decorative sounds, all added.

This guitar not only disguises the pipa, but also does all the work for the entire band.

It is simply unbelievable how much sound this guitar can produce with only six strings.

Fingerstyle!

And it’s a superb fingerstyle technique.

No, the superb finger-picking technique coupled with the superb tone control technology!

Change the playing position, suppress unnecessary overtones, change the timbre, and let the guitar produce a more exciting timbre like the pipa. When you play to your heart's content, Fu Han moves his left hand down and makes a "Zi'er~" sound, like

It was the sound of the electric guitar.

The next second, Fu Han loosened his fingers, and the sound of guitar sounded like water.

Main melody, chords, rhythm, fill-in, pattern!

Even Gu Xiaobai, the drummer, had his job taken away.

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

At this time, one person is a band!

"Fuck, my brother is so good!" Fu Wenyao looked at Fu Han's fingerstyle skills.

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

It's a bit provocative.

Look, Brother Han, I play the guitar well.

"Well..." Gu Xiaobai lowered his eyelids and looked at the drums in front of him.

Music library system, start, Helmholtz equation, operation!

In an instant, several drum heads of different sizes appeared in Gu Xiaobai's mind, and each drum head was vibrating continuously.

His brain was running at an astonishing speed, displaying the complex waveforms produced by each drum head vibration.

Compared with the sine wave of polyphonic vibration, the vibration of the drum head is an order of magnitude more complicated, and its waveform is like a kaleidoscope!
