Xu Jin groaned, and when everyone else looked at him, he was slightly puzzled: "Actually, I don't know what is going on with me, yesterday I practiced singing, and I could find the tune while practicing." ”

He frowned, "And it's not just the key of the song, any sound, except for noise, I can find the key, play a note, I can tell whether it's do or re or fa, it's a wonderful feeling." ”

Wei Zhou couldn't help but ask, "Wait, you said you could find the tone of any voice?" ”

Xu Jin hummed, "Except for the noise." ”

"How is it possible, you couldn't even tell the difference between 'do re mi fa' the other day!" Wei Zhou exclaimed.

Xu Jin shrugged his shoulders and used a joking analogy, "Maybe I suddenly received the divine empowerment of a master in a dream, right?" ”

As the saying goes, don't pretend. Forced, pretended. was forced to be struck by lightning, Xu Jin was not struck by lightning, but he was found wrong.

"What is the key that can hear any sound, it is obvious that the tune of those songs is familiar, and I am still pretending to be powerful there." A student said.

This student is talented in music and has always been a dazzling presence in the class, but today he was suddenly taken away from the limelight by a weed, and he was very unhappy.

If Wei Zhou steals the limelight from him, he can still bear it, but what kind of thing is Xu Jin, he can't even recognize the stave at the beginning, and he can sing out of tune!

Although it was only a short week, everyone knew that Xu Jin was hard working and making great progress, but he was still a weed, the bottom of the class.

This sentence caused others to nod their heads in agreement, and they didn't believe that Xu Jin had suddenly become so powerful.

A person who has been counting down all the time suddenly ran to the front with a bang, and everyone subconsciously thought that person was cheating!

It's not that they doubt that person's ability, but the fact that they count down every time makes them think that person doesn't have the ability to be first!

Wei Zhou actually wondered if Xu Jin was bragging, but Xu Jin was his friend, and friends could BB each other, but others questioned it in person and didn't give face to their friends!

Wei Zhou immediately stood up: "Wei Dicheng, what are you talking about!" ”

Wei Dicheng said: "Wei Zhou, you can't just open your eyes and talk nonsense just because Xu Jin is your friend, work hard and work hard, and you can also get our admiration by telling the truth, instead of saying something that is impossible to achieve." ”

Wei Zhou's face turned red: "I think you are jealous that Xu Jin has stolen your limelight!" ”

Wei Dicheng snorted disdainfully: "I'm just telling the truth!" ”

Seeing that the two were arguing, the teacher frowned: "It's quiet, this is a class, not a vegetable market, what's the noise!" ”

Xu Jin didn't want to talk to people like Wei Dicheng, but Wei Zhou was beaten down to save his face, he lost face, and his friends couldn't lose face because of him.

He stood up, glanced at Wei Dicheng, then looked at the others, and said nonchalantly: "I don't know how I can suddenly find the right sound, why don't you help me test the test?" ”

He didn't know how to choke Wei Dicheng, so he just said a test test, and the meaning of his words was sharp.

Now Wei Zhou is worried about Xu Jin, it's so big, what if Xu Jin can't do it?

"Brother Jin, what do you have to say to these people, we-"

Xu Jin patted him on the shoulder, pressed him back to his seat, and said lightly, "It's okay." ”

Wei Dicheng was thinking about how to make Xu Jin ugly, so Xu Jin handed him a ladder!

He was also polite, "Then let's try it, how do you want to try?" ”

"Try however you want!"

The teacher frowned: "It's class time, if you have any problems, you can solve them privately, don't affect the class!" ”

At this time, Xu Jin raised his head and asked, "Teacher, do you know what [absolute pitch] is?" ”

The teacher was stunned, and subconsciously said: "Absolute pitch specifically refers to the ability to distinguish the specific pitch of a sound without the need for a reference tone, and the moment you hear a certain sound, you can know the name of this sound, and you can accurately identify the source of the sound."

A person with an absolute sense of tone can distinguish what kind of sound it is from the noise that is usually not noticed, and this ability is one in a million, and it is said that it is innate, not trainable, and that is the wealth brought by God. ”

Xu Jin: "Teacher, I think I may have awakened [absolute tone]. ”

Wei Dicheng sneered: "Do you think you are Dong Chou, or a music star?" Still awakened? Got too much of the game, right? Didn't you hear the teacher say that [absolute pitch] is innate? ”

Xu Jin asked rhetorically: "Is it really innate, can't you go through acquired training?" ”

Xu Jin has read the [Absolute Pitch] data given by the system, and knows that it is not innately possessed at all, and it is still trained from the day after tomorrow, but it just needs a specific training period.

Without waiting for the others to speak, he continued: "Pitch is the result of artificial customization, not that such a thing as pitch has existed since the birth of the world, and the pitch set by us is different in each era.

Take the pitch of the music, A = 440Hz (the center C is six degrees high) is artificial, not natural. More precisely, it is for each people, in each era, for convenience or other reasons, even political reasons.

For example, in the West, in the Mozart era, the tone was about a minor second (semitone), which means that our C is almost equal to C#. If Mozart hears his own tune being played, it can be said that it has been turned up by a semitone.

Officials in the past dynasties used bronze bells to set the tone, often also known as yellow bells, which is also a one-tone name and has a benchmark meaning. However, because each new dynasty is to show the new atmosphere of the current dynasty, each generation often destroys the bell of the previous generation and makes a new sound.

Therefore, the pitch is formulated, and each era is different, so that no one can naturally guess what kind of pitch is used in this era, so as to have an absolute sense of tone. ”

Xu Jin's words were loud!

Wei Dicheng's mind was blank, he wanted to refute but didn't know what to refute, and froze in place.

The teacher said at this time: "[Absolute tone] rarely appears in people, just take the most popular singer, so many famous singers are the only ones who have this ability."

I haven't studied [absolute pitch] very much, and most singers can reach the top as long as they have [relative pitch], but in the case of [absolute pitch] that I have heard, people who have this ability can distinguish the name and pitch of any note without giving a reference note. ”

He pondered for a while, "It's not that difficult to test whether it is absolutely pitched, and if you really want to test, I can give you a private test after class." ”

This can be regarded as showing mercy to Xu Jin, in case it is not, there is no need to be ridiculed in front of so many people.
