"I didn't expect this kid to have such a deep understanding of music theory, and it is rare to be able to explain it in such a simple way." Jiang Ya secretly admired in her heart, looking at Liu Yufan's eyes full of encouragement.

Bai Zhifei saw Liu Yufan for the first time, and he originally had the intention of watching jokes. What are you kidding, if such a little kid can talk about music theory well, he can become a professor at the Central Conservatory of Music. This Jiang Ya is really, isn't this nonsense, if you want to find someone to talk about music theory, isn't she a ready-made candidate?

Unexpectedly, Liu Yufan's "export is extraordinary", and his opening remarks not only made Jiang Ya's eyes shine, but even he had to admit that this kid was not ordinary, although the things he said were not read from the script, but they were obviously higher. If you didn't have an in-depth understanding of music theory, you wouldn't have said it in such a condescending manner.

"Let's see what he says." Bai Zhifei also put away his contempt, and inexplicably, he was a little worried, worried that this student named Liu Yufan would be a "threat" to him.

It's funny to think about it, a child who hasn't grown all his hair can actually make Bai Zhifei feel this kind of "threat", but when he saw the unconcealed appreciation in Jiang Ya's eyes, Bai Zhifei felt that his worries were not superfluous.

"Alright, let's get started now." Liu Yufan didn't know the careful thinking of Jiang Ya and Bai Zhifei, and he gradually entered the state, and he had faintly found the feeling of being a teacher at the beginning.

"In this class, we mainly learn to understand four aspects, one is to have a preliminary understanding of staves, the second is to conduct simple rhythm training, the third is simple sight-singing, and the fourth is improvisation." Liu Yufan said, turned around and wrote four learning goals on the blackboard.

"This kid really speaks in a good way, and he actually speaks in accordance with the music theory class model of a formal music major, but can he grasp so much content?" Jiang Ya has also taken music theory classes, so she naturally knows that the content written by Liu Yufan on the blackboard is a compulsory item in music theory classes.

"Okay, first let's talk about staves. Before I begin, I would like to ask you if you are studying piano or electronic piano, and if so, please raise your hand. Liu Yufan held a piece of chalk in his hand, looked at the audience and asked.

As soon as the words ended, more than half of the students raised their hands.

Chen Siying also raised her hand, at this moment she has completely regarded Liu Yufan as a teacher, it is really Liu Yufan's performance on stage just now, too much like an experienced "old teacher", so that Chen Siying, who was waiting to see the joke, unknowingly entered the role of a student. Looking at other children, they are roughly the same, obviously ignoring Liu Yufan's age. This can be seen from the fact that they subconsciously followed Liu Yufan's words.

"Very well, let's put our hands down. It seems that most of the students have been exposed to keyboard instruments, which is good, so that at least everyone will not be unfamiliar with staves. Of course, students who have not learned keyboard instruments are also necessary to know staves. Compared with simple notation, the scope of application of stave is wider and more intuitive, and everyone can lay a good foundation for learning instrumental and vocal music and even composition by learning stave well. Next, let's get to know the stave officially. Liu Yufan said, turned around and drew five evenly spaced horizontal lines on the blackboard.

"These are the five lines of the staff, and now I ask you a simple question, does anyone know which line is the first line?" Liu Yufan said, looking at the two dozen students below with a smile.

However, his smile disappeared after a few seconds.

Because he found that none of these children raised their hands.

Jiang Ya also shook her head secretly in her heart, these children, they only know how to practice those repertoire for the exam every day, many of them are played on their backs, thinking that there are also their own students here, she also feels a little embarrassed in her heart, she can't even answer such a simple question, the foundation of music theory is really poor.

Liu Yufan's heart sank, he also expected that the foundation of music theory of these students would be very poor, because under the current examination system, teachers generally ignore music theory, but he didn't expect it to be so bad!

I don't even know the most basic knowledge of staves, even if I pass the ninth grade, what's the use, is it called being able to play the piano? Liu Yufan felt sad for these children from the bottom of his heart.

"Well, it seems that everyone doesn't know much about it, it's okay, let's start today and learn from scratch." Liu Yufan said, turned sideways in the direction of the blackboard, pointed to a horizontal line on the most side and said: "The stave starts from the bottom line, which is the first line, the second line, the third line, the fourth line and the fifth line. Liu Yufan said, drawing an oblique circle between the first line and the second line with chalk, and continued: "A space is formed between the lines, which is called the stave. The order and line are the same, and they are also bottom-up, which are the first, second, third, and fourth. ”

Liu Yufan said, wrote another symbol at the beginning of the staff, and continued to ask: "Does anyone know what this symbol is called?" ”

"I know, it's a treble clef." Chen Siying raised her hand and said, it can be regarded as meeting someone who knows it herself.

"Well, yes, this is the treble clef, Chen Siying, do you know the meaning of this symbol?" Liu Yufan continued to ask.

"Huh? Isn't it just a treble clef? What's the point? Chen Siying originally wanted to be in the limelight, but she didn't expect Liu Yufan to ask a question and then there would be a following, which stuck her. When Jiang Ya taught her, she didn't tell her what this symbol meant.

Seeing Chen Siying's somewhat embarrassed appearance, Liu Yufan secretly laughed in his heart, but he didn't show it on his face, but continued to say patiently: "Actually, this treble clef is an abstract pattern of the English letter g. We see that the clef is written from the second line, which means that it is written on the second line. We know that every note has a note name and a roll call. When Liu Yufan said this, he glanced below, and it was obvious that no one knew the difference between this "sound name" and "roll call". He shook his head in his heart, the foundation is too poor, it seems that literacy is not an easy task.

"For example, when we sing music, we sing do, ri, mi, fa, sol, la, si, which are the seven tones of the roll call, and in turn, they also have a sound name. You can simply understand that the roll call is the nickname of each sound, and when we sing it, we have to call it its nickname, and the sound name is the name of the sound, which is a written language, and the sound names of these seven sounds are C, D, E, F, G, A, and b. Liu Yufan said as he wrote down the names and roll calls of the seven tones on the blackboard, and then pointed to G and said, "Look, this G is the name of SOL, that is, the name of the sound." ”

Liu Yufan said, pointed to the treble clef with his finger, and continued: "Now that everyone knows that this treble clef represents G, and it is recorded on the second line of the staff, it means that what should be sung on the note recorded on this line?" ”

"Sing G," said some of the students below.

"No, it should be sung", and soon someone realized the mistake.

"Yes, everyone understands very quickly, if it's a score, of course we have to sing its sol-call, which is sol, this time you know what the treble clef means." Liu Yufan said with a smile. Seeing that the students below were all stunned, he exhaled secretly. It took so long just to explain a treble clef, and he was really worried that he would speak too fast and these students would not understand. It seems that his efforts have been effective, although it is slower, but it can give them a deep understanding of the staff, which is also his purpose.

"So with this g as the boundary, down to F, E, D, C, that is, FA, MI, RI, DO, then some people may ask, by the time it comes to ri, it is beyond the range of the stave, so what to do? It doesn't matter, the excess part, we call it 'plus line' and 'plus room', for example, this ri, is written on the 'next plus room', and the lower 'do' is recorded on the 'next plus line'. ”

Liu Yufan spoke very carefully and slowly, but the two dozen or so people below understood it very clearly. Obviously, Liu Yufan's easy-to-understand explanation is easier for them to accept.

Next, Liu Yufan didn't talk about anything more, but randomly asked a few questions on the blackboard to check the results of his learning. The result was satisfactory to him, and most of the people had already mastered what he had just said.

"Okay, about the staves, we've been exposed to so much content today, and then we'll do a few sets of rhythm exercises." Liu Yufan said, wrote a few rhythms on the blackboard, and then said: "I will talk about the way of practice, this x symbol, only represents the time, not the pitch, you can use the way of clapping, and at the same time shout 'big' in the mouth, if you encounter a rest, shout 'empty', come, everyone do it with me......"

Ten minutes of rhythm practice is followed by sight-singing practice. Liu Yufan's direct sight-singing of the stave, of course, is limited to the content of the stave he talked about today, and the effect is satisfactory, although it still needs to be tried to react for a while, but by the end of the training, these 20 people can already sing a simple melody under the guidance of the piano.

In the last link, that is, the improvisation session, Liu Yufan was a little depressed, although the few exercises he prepared were the simplest, basically a simple paragraph, and the space left was also monophonic, but most people still couldn't do it. Apparently due to a deficiency in harmonic knowledge. And harmony is not what Liu Yufan wants to talk about today, so seeing that the effect is not good, Liu Yufan decisively gave up.

The class lasted fifty minutes, but the order was always good, and no students showed impatience. This is also thanks to Liu Yufan's interactive teaching method. In the whole class, basically the time of talking and the time of practice were kept at one to one, almost every student got the opportunity to practice, and Liu Yufan gave a positive evaluation to almost every student, which is impossible in the classroom at this time. Most teachers still pursue the teaching mode of "I talk and you listen", although sometimes some students will be allowed to do questions on stage, but it is far from the "interaction" of Liu Yufan.

In terms of effect, this music theory class is very successful, there are lectures, exercises, and interactions, and students use their eyes, ears, mouths, and brains in class, and almost every sense is used.

"Okay, let's go here for today's class, don't forget to do these questions on the blackboard when you go back, I'm going to spot check it next time, let's get out of class." Liu Yufan "waved his big hand" and stepped off the podium, only to find that Teacher Jiang Ya was looking at him with a strange look.

(Four more will be sent, everyone should rest early after reading it!) Good night! ）
