The glasses man's name is Yang Zhenyu. He was in a bad mood.

The reason why he sings is very simple, to make money. Ming'er is going to pay the rent, and he has to scrape together 500 yuan tonight. Yang Zhenyu has been singing for three days, and the first day was not bad, with an income of 42 yuan and 5 cents. The next day it was over, and only 13 yuan were collected. Today...... Alas, it took half an hour of singing to earn 1 dollar.

There were 13 yuan in the piano case, and 12 of them were put by himself.

"I Miss You Every Day" was too broken to sing, and he himself knew that he was sulking while sitting on the piano case. Seeing that Fang Yan wanted to play the piano and sing, he squinted and glanced at him.

Well, this man is very dirty, and he is a poor man. It's quite pleasing to the eye, but the hair is so short, it looks like it has just been released from prison. Yang Zhenyu bombarded him impatiently, and said angrily: "Go and go, play while playing." Don't you see that I'm making money here? ”

"Come on." Fang Yan nodded with a smile and left.

"Hey......"

Fang Yan was not angry at all, and turned to leave, but Yang Zhenyu was embarrassed. Come out and sell it in these days,...... No, when he was singing, there were passers-by who wanted to play his piano. At that time, he was in a good mood, so he let them play. Passers-by will fiddle twice, play a little ballad, and self-absorbed for a few minutes. After playing, throw away a little change, and leave with a few polite words. After a few times, he felt quite bored.

I'm singing, for the sake of ideals, and rent, what kind of mess are you making when you're full of food and drink.

But this person doesn't look the same.

Life is so ironic. A few seconds later, Yang Zhenyu made a decision that changed his life.

"Hey, hey! Call you, buddy. ”

Yang Zhenyu summoned Fang Yan back, glared at him, handed him the guitar a little reluctantly, and said, "Be careful with the dotted line, don't knock it." ”

"Thank you." Fang Yan nodded.

Fang Yan has a temperament on his body, I don't know why, Zhenyu has a good impression of him. He thought for a moment, took out a cigarette, handed it over with the lighter, and asked, "One for you?" ”

"Thank you."

Fang Yan lit the fire. He was 17 years old when he entered prison, where he learned to smoke. The cigarette is a big front door, spicy and choking, Fang Yan smoked, thinking that this guy is also quite poor.

Fang Yan put on the strap of his guitar. The first thing he did was to bend down and turn off the speakers and unplug his guitar again. The brand of the guitar is Epiphone, which is a very famous brand, but it seems to be a domestic imitation of a fake. However, this is also a veneer, and it is estimated that it can be sold for 1,000 yuan a piece.

The acoustic guitar is also equipped with a pickup, commonly known as the electric box piano, which can be connected to the speaker to play.

Fang Yan turned off the speaker for two reasons, one is that the speaker is a bargain, which is too bad. Second, this is a pedestrian street, there are no cars, and there are no shops to play music, except for the sound of people, it is quiet enough that there is no need to amplify the volume.

He plucked the fifth string of his guitar with his right hand, the A string. The strings vibrated and an open bass sounded slowly, and he twisted the knob of the headstock at an angle.

The guitar has a total of 6 strings, so it is also called a six-stringed instrument. The guitar is a perfect instrument because the human hand has 5 fingers, and playing 6 strings is almost the limit of one hand. The 6 strings are, from highest to lowest, E, B, G, D, A, and E. Fang Yan quickly adjusted.

Finally, he pressed the 7th and 5th frets of the two strings, played the overtones, and confirmed that the piano had been tuned.

On the neck of the guitar, there are many metal strips, which divide the neck into grids, and each grid is called a fret. There are two specifications of the guitar, one is the classical guitar, which has 12 frets, and the rest of the folk guitars, electric guitars, etc., are all 14 frets.

Counting from the headstock, the first grid is called the first fret. From the 14th fret onwards, there is still a grid, and you can continue to play, but you use it less.

Fang Yan turned off the speaker just now, and Yang Zhenyu was very unhappy. When Fang Yan was silently tuning, he sat with his legs crossed, with a look of disdain.

It's a pretending criminal, he sneered. It's also tuned.

"Hey, look at this place, no one listens." Yang Zhenyu pouted, looked around, and said. "You look at these guys, they don't understand music at all. What's the use of your tuning? ”

"That's it."

Fang Yan's left hand clasped the strings and said with satisfaction. This guitar is in good condition, it has been bounced, and the tone is relatively accurate. Domestic copycat manufacturers have a conscience.

"Well, you can play, I'll listen." After Yang Zhenyu finished speaking, he suddenly thought of something, and a spirit sat up straight and asked, "How do you tune the tone?" ”

"Straight to tune."

Yang Zhenyu swallowed a mouthful of spit, opened his eyes and asked, "Do you have an absolute sense of tone?" ”

Absolute pitch is a colloquial saying. Sound is produced by vibration, and each sound has a frequency of vibration and also has its own pitch. For example, one defines the frequency of standard A as 440 Hz. People with an absolute sense of pitch can sing this A accurately without any outside help, and the score is exactly right.

Absolute pitch is a rare talent, and the approximate count is 1 in 10,000 people. Of course, after a long period of practice, there are very few people who can master the absolute sense of tone.

What is the concept of innate absolute tone? For example, if you hear the brakes of a car squeak, you will say the pitch of that sound. When you hear the door open, you can tell what it is. When you hear a baby crying, you can write it down. Birds, streams, sneezing...... You can tell the pitch of any sound you hear.

If it's a singer with an absolute sense of tone, it's amazing. You don't need to listen to the cues of the accompaniment, you just open your mouth and come, you won't be out of tune at all, it's impossible to go out of tune.

However, people with an absolute sense of sound are sensitive to sound and tend to be more painful. For example, just now, Fang Yan felt extremely uncomfortable when he heard that Yang Zhenyu's guitar was not accurate.

Musical instruments, including drums, all need to be tuned. Only when the sound is correct and accurate can it sound good. Generally, when you play the guitar, the first thing you do when you take a piano is to tune it.

Ordinary people have to use a timpani to tune, and it can be anything that can provide a standard tone - the blind tone of the telephone, which is A. There are also ways to play a key of the piano, play the harmonica, an ancient tuning fork, an advanced electronic tuner, and so on. Folk guitars generally use a blown 6-hole timpani, which corresponds to the 6 strings of the guitar.

Now it's much more convenient, the mobile phone can be installed with the APP of the electronic tuning meter, pluck the strings, and directly tell you whether the pitch is low or low.

Yang Zhenyu was taken aback. He was a little jealous and unwilling, so he took out his mobile phone from his pocket, opened the tuning APP, and muttered: "Don't move, I'll try." ”

The red light is not allowed, and the green light is accurate. He plucked the strings one by one, brushed and brushed, and it was all green.

Mobile phones don't lie. Yang Zhenyu was convinced, sat back on the speaker, looked at Fang Yan in a daze, and didn't know what to say. This man is not simple, he seems to be able to play a little piano.

But young people are always arrogant. Yang Zhenyu raised his chin slightly and made a gesture of please. The meaning is very clear, you play, I see what you can play?
