Variation is to add some modifications to the original melody or make some deformations around the original melody, so that the music has a richer expression form, and it will change more when sounding and playing, which is conducive to the music to better express its emotions. There are many forms and methods of variation, and a same melody can change many forms of variation through different methods.

The improvisational variation of the theme requires the player to have rich improvisational abilities, which is different from the complete spectrum of playing classical works. Variations give the player a lot of room for performance. The same harmony formula can be expressed by column chords, or by pilophones, which can be alternating parts and changing rhythms, but no matter how it changes, the skeleton of the music is still the content of the harmony formula.

Lu Wei looked at the six harmonic formulas written on the blackboard, three major and three minor, all of which are very ordinary harmonic formulas, and there are also review materials. There is nothing to keep in mind for such questions because their difficulty is reflected in an improvisation. Although the students participating in the competition have done some practices in a targeted manner, the difficulty of composing himself is far greater than the difficulty of playing a ready-made piece.

Lu Wei looked at it, an invisible smile appeared on his lips, and he thought to himself: "It turns out that there is this, so it's easy to deal with it."

Lu Wei looked at the third one, a major harmonic formula: I→V→VI→III→IV→I→IV→V→I. This formula is a completely terminated formula, starting from the major chord and ending on the major chord. Several secondary chords are added in the middle, adding some lively colors.

The reason why Lu Wei smiled was very simple. He was so familiar with this formula. Lu Wei, who liked to play popular pianos in his previous life, could tell at a glance that this was the famous American pianist George.

The standard harmonic formula of "Variationsonthe Canon" in Winston's album "December", haha, this is Lu Wei's favorite popular piano piece in his previous life, and he has to play it almost every day. Although this song was also used as scene music in "My Savage Girlfriend" and added some changes, Lu Wei still likes George more.

This song by Winston, because he sounds closer to the original.

Of course, Lu Wei was not playing George.

Winston's original version of "Cannon" was a version downloaded by later generations on a "Popular Piano Network". Lu Wei remembers that the guy who revised the score seemed to be called "Cold Wind". This is also Lu Wei's favorite version among many revisions.

Lu Wei was not worried that the judges would think that the judges would be considered plagiarism by playing this song because "Kanon" is not the name of a song. To be precise, Canon is a kind of music, which literally means "wheel sing", which originally means "rule". It refers to a writing technique of polyphonic music. The tune of one part follows another from beginning to end, and the same melodies of several parts appear in sequence, cross, imitate each other, chase and entangle each other, while the parts are almost monotonously repeated until the end... the last conclusion and the last chord, they will merge together and never separate. The extremely entangled music is like two people following life and death. The music written with Canon's technique is called "Kanon's song". In this sense, Lu Wei only played this chord formula in Canon's composition.

Although I haven't played this song for a long time, that kind of skilled muscle memory can completely allow Lu Wei to play it smoothly on the piano, because this song is not difficult at all, and can be controlled by Lu Wei's previous level, not to mention now.

The game was going on, and the first one to play was the fat Li Wei with freckles. She chose the fourth one, which was a minor harmonic formula. It seems that most girls like the minor tunes of the gentle and dull petty bourgeois mood.

However, Li Wei's performance is indeed unreasonable. She simply changed three times, but suddenly it was semi-decomposed, decomposed, and then changed the main melody to the left hand, and then it ended. Looking at the time, it was less than a minute.

Several judges looked at each other and tried hard to endure the smiles on their faces. They had never seen such a "creative" variation.

However, after all, it was at the home court of Nanshi. Even if you were to take care of your face, it was difficult for several judges to score too low. Kong Xiangdong, the lowest score, also gave a passing score of 63 points. Although the other judges gave high points, they did not exceed 70 points.

Li Wei also felt that her performance was a little too simple, so she smiled at the judges embarrassedly, bowed and walked off the stage quickly.

The performances on the field later were also worse than the above. In fact, Lu Wei believes that it is unreasonable to set this item in a non-professional competition. If you have not learned composing professionally and systematically, even if you have time to prepare, it is still too difficult to play a completely self-created piece of music. Lu Wei knows that in fact, many students are not writing it themselves, but specially prepared by teachers who know how to compose music.

After Zhao Jie went up, he played the second major chord, which was quite neatly played. Lu Wei knew that this song must have been written by Teacher Gao, because Lu Wei also had one in his hand, and there was one of them.

Dong Kun, who was on the sixth, performed well, which made Lu Wei's eyes lit up. Although this was also a completely self-created song, it was obviously already professional. It was excellent in terms of neatness and the display of skills, especially the performance of showing off in the middle, which received warm applause from the audience below.

After playing, Dong Kun stood up and bowed to the audience, then bowed to the judges, thinking: "The song prepared by the teacher is really good, but it's a bit underestimated in such a competition."

As expected, Dong Kun scored a high score of 91 points in his performance, which is the highest score in the whole game so far.

Li Deqian in the audience was worried secretly. Although the variations of the harmony formulas had been written by himself and Teacher Gao and printed and distributed to the students before, it was obvious that the variations that Dong Kun had just played better than the music he prepared in terms of skills and artistry, and he couldn't help but worry about the competition again. He knew that even if Lu Wei played the music he prepared perfectly, he would definitely not have the score of Dong Kun. It seems that the results of this part were

It won't be too good. Li Deqian thought, and couldn't help feeling unfair about the use of Kong Xiangdong's students to participate in the competition in the South Master, but he couldn't catch any talk. After all, Dong Kun is indeed a student in the music class of the South Master, so he had to rely on Lu Wei's afternoon competition. Li Deqian was still very confident about Lu Wei's "Moonlight Sonata". He believed that no matter how difficult the song Dong Kun chose and how good he played, he was only at Lu Wei's level. After all, this song was a concert-level song.

It was Lu Wei's turn to play. When Lu Wei slowly left his seat and walked towards the piano, the cheerleaders of Changshi collectively shouted: "Come on Lu Wei, come on Lu Wei!" Lu Wei waved his hand to the bottom with a smile. He saw that Xiaoling was also waving his arms at him hard in the team. This situation was much like the scene when he participated in the sports meeting in his previous life.

Retracting his thoughts, Lu Wei walked towards the Kawai grand piano in the middle of the stage, his eyes became extremely hot, and he could finally play this beautiful professional piano.
