Paul Harrison is a German-American, in his sixties, with a burly build and red hair.

He immigrated to the United States during World War II and was penniless when he first arrived. Because he was good at the accordion, he got a job in a tavern. He played the accordion and sang in the tavern, and sometimes worked as a bartender, a job he has been doing until now.

He is also a member of the band "Owl", although he is a guest member, and usually he has to work at night and only has free time during the day.

Barthes, on the other hand, has to go to work during the day and have free time at night. Because of this, the composition of their band changes frequently.

"Hey, Paul! This is my son Alex! Bart introduces Alex to Paul, and then explains Paul's identity to his son, "From now on, Paul will be your teacher, and he will teach you how to sing in front of an audience." ”

"Hello, Mr. Paul!" Alex greeted Paul obediently.

"Ha Luha, what a smart boy!" Paul was so happy that no one had ever called him Mr. so respectfully!

After Barth handed over his son to Paul, he left in peace. He still has a lot of things to do and doesn't have time to be around.

Paul didn't come empty-handed, he had an accordion on his back. He believed that it was best to sing with accordion accompaniment.

"Let's get started now!" Instead of teaching Alex how to sing right away, Paul made a request: "I heard you play the guitar well?" Can you play it for me? ”

Alex nodded, picked up his guitar, put it on his back, and played a song without saying a word. After a few days of practice, his playing level has skyrocketed. On the one hand, it is because he is still young and accepts things quickly, and on the other hand, he learns hard and uses the right methods.

Crucially, he found that "simulated memory" was very useful for learning other people's playing techniques. This is normal, when humans first start learning, they will always find an object to simulate.

A guitar tune, played very quickly, not played very well, not played badly.

When Paul heard this, he was secretly surprised. Let's not talk about Alex's age, let's just say that people who have only practiced for less than a week can play so quickly. He complimented Alex a few times and said, "Alex, I think you should learn the accordion first." ”

"So, sir, when am I going to start learning the accordion?" Alex couldn't wait to ask, he had only seen the accordion before, but had never learned it! Singing or something, in fact, he himself is secretly practicing.

Paul was so pleased with Alex's studious attitude that he said, "Have you ever seen an accordion before?" ”

"Sir, is the accordion the thing you carry on your back?" Alex noticed that Paul was carrying a large thing with a keyboard and buttons, which was divided into three parts, the left side was like a shrunken piano keyboard, the right side was a row of round buttons, and in the middle was a folded bellows.

"What a smart boy! Yes, that's the accordion! Paul took the accordion off his back and handed it over.

The accordion was a heavy creature for a four-year-old, and Alex had to exert all his strength to hold it securely. If you want to play in your arms like an adult, it's a hard job! Luckily, the accordion has a strap and can be carried on your body.

Paul was also very happy to see that Alex liked the accordion, and he slowly introduced Alex to the various buttons of the accordion and the origin of the accordion.

"The accordion is a reed instrument that can be played both solo and accompaniment, and it is an instrument made by borrowing from the principles of Chinese sheng reed articulation."

"I really didn't expect it to be borrowed from a Chinese instrument!"

Alex was Chinese in his previous life, and he had never heard of the accordion, and he had only just heard Paul talk about it.

In fact, more than one instrument was originally made according to the principles of Chinese musical instruments.

In 1777, the Chinese musical instrument "sheng" was introduced to Europe by the Italian missionary Father Amauite, and soon after, Europeans made similar instruments based on the pronunciation principles of this Chinese instrument. These were the precursors to the accordion, but most of them were eliminated before they could be disseminated.

The real hand-drawn organ is the mouth-blown Ola made by the German Derek Bujmann in 1821. Soon a hand-controlled bellows and buttons were added to the Ola violin, and later the Austrian Cyrillus Demian combined the various predecessors of the accordion on the original basis to successfully improve and produce the world's first accordion accordion.

To this day, the accordion is still used as a accordion in various parts of the world.

In Germany, and even throughout Europe, many rural farmers have accordions in their homes. Compared with the piano, it can not only play a beautiful melody with a single voice, but also play a multi-part piece, and can play rich harmonies with both hands like a piano. The most important thing is that it is inexpensive, and it is a very suitable instrument for poor people.

From an early age, Paul knew how to play the accordion, which was one of his favorite instruments.

In some old-fashioned European black-and-white films, the entertainment of the poor is to gather in a group, with one person playing the accordion and the rest singing and dancing.

The most memorable accordion performance for Alex was a video I watched on the Internet, which was a movie version of the song and dance clip of "Ievan Polkka", the predecessor of "Song of Throwing Onions", which was widely circulated. In that video, a homeless man plays the accordion, while the others sing and dance in a circle, looking very happy.

At that time, Alex thought that the accordion, an instrument that looked weird, was very powerful, because it was such an instrument that played the role of a band.

Paul's method of teaching was simple, he played the accordion and let Alex practice. Of course, he will still teach some of the most basic playing techniques one by one. The piece he played was called "In the Sky of Paris", and it sounded very kind of European countryside.

After Alex listened, he memorized every detail of Paul's movements, and when he wanted to repeat those movements, he found that it was not as simple as he thought. He played, stumbling, and the music was slow and fast. The more he tried to play well, the harder it became to play well, and it was clear that he remembered all of Paul's movements.

"Ha Luha, yes, yes!" Paul didn't expect Alex to be able to play from beginning to end after listening to it once.

"But I can't play as well as you, teacher!"

"I've been amazed by your performance! Many children have to teach even the basic notes several times when they first start. ”

Regardless of what Paul said, Alex felt like he wasn't as good as he should be. Apparently he had tried his best to learn, so he almost used "simulated memory" to repeat Paul's movements, but he still couldn't play smoothly.

Using "simulated memory" can be learned faster, but it requires more energy and has limitations on learning skills. He thought about it, only using "simulated memory" to learn other people's skills, and at most he would learn seven or eight percent, and when he used it in the future, he would never exceed this level. When he really wants to use it, he can only "simulate" it all the time, which will exhaust him.

Only by studying seriously, you can use "simulated memory" to break through when it is critical, and that is the right way to learn skills.

Paul felt that he could not teach too much at once, so he said, "I see that you have learned almost well today, so now you can practice it a few more times." ”

After that, he let Alex practice the accordion alone. At this time, Alex was practicing, and at the same time, he was thinking about how he could learn Paul's accordion playing skills faster.

Thinking about it, there is only one way to go, and that is to practice honestly. Eventually, he simply didn't think about the problem and stopped practicing the accordion. He entered the spiritual space he had created, which was still in the shape of a hut. It was still filled with the light of the setting sun, and he lay on that bed, quietly in a daze.

Although he was in a daze, he knew that his body was now under a lot of pressure, consuming energy bit by bit. Once exhausted, he had to replenish his energy through deep sleep. Yes, that's what he's for, he wants to sleep.

However, when he was in a daze, his head was not blank. Suddenly, he suddenly thought: "Let's create living objects in this spiritual space, it looks quite interesting!" ”

When he created this space before, he had never thought of creating other life. He once wanted to extract the person in his memory directly, but found that it was useless, and the person who was drawn was like a puppet that couldn't stop, repeating the actions in the past memory scene.

"If you don't extract it from your memory and generate a person directly in this space, will he move? If he can move, can he speak? If he could do all of this, what about thinking? ”

The more Alex thought about it, the more excited he became, he sat up, concentrated, and began to "make man"!

At this time, he realized that people and objects are completely different. At least "creating man" is a hundred times more difficult than "creating things"! He has no way to create a new person out of nothing, he can only find the prototype from his past memories to learn from, so that it is possible to create it.

At the same time, he found that the more familiar people are, the easier it is to create. Also, the more fresh the memory, the easier it is to create.

"Who made it? Bart or Angel? ”

Alex was most familiar with these two people, and he thought about it, forget it, or not make them. He was worried that after creating his parents, if this virtual person had the mind of his parents, he would feel very embarrassed at that time. If the person who created it couldn't think, then he would feel a little embarrassed.

"Then Paul! He's the guy I've seen in my last memory, and it's an experiment anyway, and I'll have a chance to observe him in the future. You can compare it and see what is different. ”

Alex did what he thought of, and he quickly built a model in the mental space and built Paul's body. Outwardly, the object of this "man" looks exactly the same as Paul's, and there is no difference. However, Alex soon discovers that the person he has created is a doll, a realistic doll.
