At night, Duan Yuying, who was uneasy in the room, sat next to the piano. Seeing Li Li sitting in the upper head staring at him, she couldn't help but lower her head, worried, but she forced herself to calm down.

The wife said that the king had any problems and needed her to solve them, but what did a man and a woman do here?

Sure enough, can't you avoid it?

Now that things have come to this point, Duan Yuying can only accept her fate, after all, this is a matter of time sooner or later.

But this is not a dormitory, it seems to be a piano room. When she thinks that she is being brought to the other party here, she feels sad.

Footsteps sounded, and two more entered in turn. Duan Yuying looked closely and found that it was Xue Yuechang and sister Xue Yue'e.

Several more maids followed in and brought Qin, Se and Zheng respectively.

After a while, Li Li saw that the instruments were all arranged, and coughed dryly. The maids waited aside and stood in a row, while the Xue sisters sat at the lower right head and Duan Yuying sat at the lower left head.

"Madam Duan, from today on, she will be the female teacher in my mansion and teaches Qinyi." Li Li introduced Duan Yuying's new identity to the Xue sisters.

Then he looked at Duan Yuying: "However, I still have some things that I need Duan's help, that is, to improve the instrument."

When Duan Yuying came, she had heard her wife say the reason, which was "improving the instruments". Looking at the strange instruments in front of her, she didn't know how to express her opinion.

"Miss Duan is well versed in music, and so is Mrs. Xue and Mrs. Xue. Then, let me talk about it..."

Common string plucking instruments in this era include pipa, zipper, zipper, zipper, zipper, and zipper. The structure of the pipa, zipper, zipper is very similar.

The zither has seven strings, which is a seven-string zither; the zither is an accompaniment instrument, which mainly accompanies the zither. It is said that the zither originally had fifty strings, but now the zither is generally thirteen strings, sixteen strings, etc.

The zheng is a thirteenth string, while the fifteenth string is more common.

The three types of musical instruments require the player to constantly pluck the strings with his fingers, which will damage the fingers, so the player will wear finger protection, such as the "anter finger" made of deer antlers.

Or use a pick, which is similar to playing the lute.

"Describing a couple with a good relationship, there is an idiom 'Qin and Se', so I was wondering, since Qinse and Se are all stringed instruments, why can't they be put together and become a new instrument."

"This new instrument, played by one person, may achieve the effect of harmony between the zither and the zither?"

Duan Yuying almost blurted out: How is this possible!

"You must want to say, how is this possible, right?" Li Li put a normal piano in front of him and made gestures to play the piano.

He doesn't know how to play the piano, and he does this action just for the convenience of explanation: "One string, when plucked at different positions, will produce different sounds, and seven strings can have many sounds."

"New musical instruments are similar to the combination of zither and zither. They are arranged on them with strings of different lengths. Each string makes a single sound when it is plucked in a fixed position."

"Then, this new instrument has dozens or even hundreds of strings, including the main tones of qin, si, and zheng, and plays them alone."

Duan Yuying felt that such a thought was simply delusional, and the Xue sisters didn't know how to respond.

"You will definitely say that if a person, with his hands, can't touch dozens or even hundreds of strings, he can't even take care of it, right?"

Li Li asked and answered: "So, this kind of instrument does not require the player to pluck the strings directly with his hands, but pressed the skull called the 'key' and plucked the strings from the skull."

After saying that, he clapped his hands, and after a while, several maids pushed an instrument in.

The instrument is not small in size, like an enlarged desk, about one meter long, about four feet high, and about seven feet wide.

A Hu bed was placed in front of the instrument, and Li Li sat on it, and it seemed that he was going to demonstrate the usage. Duan Yuying hesitated when she saw this, wondering if she should stand beside Li Li.

Xue Yuechang did not hesitate and immediately "attacked" with her sister and stood around Li Li.

Duan Yuying stood outside Xue Yuechang. When he looked carefully, he saw that there was a row of black and white strips of objects at the front of the instrument, like a "comb tooth".

"This black and white long strip object is called the keys and is the front end of the machine." After Li Li said that, he opened the top cover of the instrument and supported it with a strut.

"Look, there are a hundred straight strings inside, with different lengths."

Duan Yuying looked carefully and was shocked: Sure enough, there were dense vertical lines arranged in this instrument, that is, neatly arranged strings.

From right to left, the length of the string gradually increases.

If there are so many strings, if you come to pluck them alone, you will not be able to take care of them at all.

"You guys look carefully, I'll press the keys now..."

After Li Li finished speaking, he pressed a key, but saw that the keys were linked to several leverages. The small hammer at the end of the lever hit a string and made a sound.

Li Li pressed the other keys one after another, and the small hammers linked to each key hit the corresponding strings and made different sounds.

This is the principle of piano pronunciation.

The fingers hit the piano keys, and the piano keys drive the string striker through the connecting rod.

There is a small hammer at the end of the string striker, called the string hammer. The string hammer will be lifted after being driven by the string striker, and then the tensioned string (wire/iron wire) below is hammered.

A string hammer hits the string, and the string vibrates and makes sound.

The string hammer must be lifted immediately after hitting the string, otherwise it will affect the vibration and sound of the string. However, the sound will not disappear immediately after the string vibrates, so a string suppressor must be used to stop the string from vibrating.

This is the mechanical structure of the pronunciation of pianos. The principle is simple. Li Li once heard someone introduce the principle, but it is not easy to make the principle described in a few simple sentences.

After he proposed the concept of a complete string strike and string suppression device, it took the field technicians seven or eight years to make mature products.

The structure of the string-strike and string-suppressing device made is indeed very simple. There seems to be a layer of window paper between theory and reality, but it took seven or eight years to break this layer of window paper.

The Xue sisters and Duan Yuying experienced the "playing the piano" separately, and they felt unbelievable: There are such wonderful musical instruments in the world?

"This is just a principle verification machine, that is, a trial product. The instrument I want covers a wide range of sounds, so there will be only more strings, not less."

"The number of sounds that can be made by stringed instruments, zithers, zithers, and zithers can be accumulated, and there may be more than 200 strings. Then, there may be no less than 200 strings of such instruments."

"But it is impossible for the instrument to have more than 200 buttons, otherwise one person will not be able to play it."

"A string-beating device does not necessarily only hit one string, but also can hit two or even three strings at the same time, so it can make different resonance sounds, which requires exploration."

"I can make the structure of the musical instrument, but I can only ask you to do the tone of the strings. Moreover, the string is not a silk string, but an iron string, or a steel string."

"Steel string?" Duan Yuying was surprised, Xue Yuechang and Xue Yue'e also looked at Li Li in surprise.

"That's right, so you need to hit a hammer to hit the metal strings. It's not possible to use your fingers." Li Li pointed at the keys, "There are fingerings for playing the piano, so there are also fingerings for playing this kind of harpsichord."

As he spoke, he was full of longing: "The strings played by this kind of musical instrument should be steel strings, so I call it 'piano'."

Piano is a very complex instrument with a wide range of sound ranges. If you only know the pronunciation principle, instead of a professional piano maker, you will not be able to make it.

Li Li only initially solved the structural problem of the piano, and the structure still needs to be improved, so the piano in front of him is actually a semi-finished product.

As for sound quality, he did not understand the rhythm at all and could not be further improved.

Therefore, he presented the semi-finished piano as a gift to the emperor who was proficient in music, giving the other party a surprise.

It also includes the wire drawing process for steel (iron) strings. In this way, he can openly organize a wire drawing workshop without being questioned about the purpose of the wire drawing process.

The cultural development of Liang State was extremely prosperous. The scholars and officials could not play the piano and could not understand the music. The royal family, Lanling Xiao, was famous for their literature, and the emperor was a typical literary youth.

When the emperor and his ministers saw the piano, they would definitely be obsessed with such complex and magical instruments.

Then mobilize music officials, musicians, and even all "professionals" to further improve the piano. Only in this way can the piano be formed quickly.

That was the general direction. Li Li asked three "professionals" around him who were good at music to help. First, let the three of them have something to do and not think about anything.

Secondly, it is to determine the "scalar", divide the "voice range", and adjust the "sound quality" according to his needs.

The method of formulating and optimizing the 'play' is the fingering method.

Li Li said it roughly, and Duan Yuying was so shocked that she was extremely shocked.

She could not describe her shock at this time in words. Although it was the first time she heard this idea, she could imagine that the complexity of this kind of instrument was far beyond any instrument she knew.

She can play the piano, but she doesn't know much about making the piano, but she can tune it. However, with her ability, she has to set more than 200 notes, and she feels unconfident.

Xue Yuechang and Xue Yue'e were also not sure. They learned to play the piano since childhood and of course they could tune it, but it was too difficult to tune more than 200 notes.

The two of them couldn't help but look at Duan Yuying, but saw that this person was thinking, mistakenly thinking that the other party was sure, and they felt a chill on their backs.

Duan Yuying has outstanding appearance and can already attract the "greed" of the king. If she compares their sisters in terms of music, what should she do in the future?

Xue Yue'e made a quick decision and asked: "My Lord, can there be a deadline?"

"There is no deadline, because it is very difficult. I won't force you, just do my best." Li Li looked relaxed, "Take it slow, don't be anxious. Tuning is very hard, and you won't be fat in one bite."

"June, may I ask for specific requirements?" Duan Yuying raised her head and looked at Li Li with a determined look on her face: She wants to try to complete this complex instrument.

It is not to please Li Li, but to challenge herself. Since she likes music, if she can complete such an instrument, it will be worth her life.

"My requirement is that an instrument can play the tone of the piano, si, zheng. Note that it is the tone, not the sound quality..."

"The treble is sweet, the midrange is accurate, the bass is heavy, in short, it is transparent."

Li Li was actually memorizing the lines and then added: "This instrument covers treble, midrange, bass, for example..."

"There can be both the tinkling spring water and the roar of waterfalls; there can be gentle drizzle and strong winds and rains; there can be whispers and whispers and whispers to the sky."

"When playing, it makes people feel like walking on a forest path, with birds singing and flowers singing in their ears, or riding a horse racing in the vast field, with the howling of the biting cold wind..."

Li Li said slowly, Duan Yuying listened and was fascinated.

If there really is such an instrument in the world, she really wants to play it, turn into a bird, and fly freely.

As Xue Yuechang listened, she couldn't help but look at her sister. Seeing that her sister was also excited, she couldn't help but feel excited: If she could complete such an instrument, it would be really worth her life.

"Don't worry, just to improve the instrument, the heavy responsibility is not on the shoulders of you three."

Li Li said and laughed: "Actually, I have dedicated this instrument to the emperor. The emperor will definitely let the musicians of the Taile Administration improve this musical instrument that has never been seen in ancient times."

"Think about it, so many skilled craftsmen have worked hard to find ways to improve this instrument. Everyone has high firewood and flames. Will it be long before the piano is truly released?"

He didn't want to undermine the enthusiasm of the three, and said, "But I hope you can perfect this instrument for me, because I have many good songs that need to be played according to my preferences."

"The court mobilized manpower to improve the piano, and I'm afraid there will be a lot of debate. I don't know when it will be finalized. I don't want to wait too long."

Duan Yuying was excited when she heard this: "I wonder what good songs are there for you?"

"Do you want to hear it?" Li Li looked at Duan Yuying, then looked at Xue Yuechang and Xue Yue'e. Seeing the three of them nodded, he said, "Then, I'll sing a song."

Li Li is preparing to hum a famous song that is "looped" in countless supermarkets and shopping malls.

"The title of the song, "MY LOVE", is the Western and Chinese name "My Love".
