"We're talking about the cello above, let's talk about the violin, and when it comes to the violin, I'm afraid it's a much bigger system. ”

"We need to start with the origin of the violin, and when we talk about the origin of the violin, we must involve the artistic views and technical methods of the original designers of the violin. Modern mathematics is a tool of technology, but in the Renaissance mathematics was the initiation of art, and proportions and sequences were elements of aesthetic research and were adopted by all artists. A master violin maker is not just a methodologist, but a true artist, and the overall harmony and consistency of the violin dominates the entire design. ”

"The shape of the violin can be thought of as being composed of many curved lines, and the outline of the violin can be sketched with arcs, but not all of them are arcs. The original designer first used a compass to draw the arcs of each segment, and then used an artistic eye to correct and bend the arcs into the final shape. Use a pen and knife to modify the pattern as it is made, and polish and smooth a curve made up of a sufficient number of arcs. The curves at the top and bottom of the violin are designed in the classic way of designing the arch of the bridge, and some people think that they resemble the shape of a basket handle. The curvature of the plate resembles a vertical chain, and the spin head is modeled after the graceful spiral design of the ancient Greek columns. Of course, in addition to using arcs, there are also some other lines that may be taken. ”

In addition, the compass and ruler were the tools of both ancient geometricians and medieval architects, as well as tools for designing musical instruments. Especially in the case of violins, the average instrument designer tries to place the center and arc of the circle in different positions, and draws the outline of the instrument after many experiments. However, the master instrument designer has carefully conceived before designing a shape that is both beautiful and meets the requirements of performance, and at the same time, carefully considering the consistency of the inside and outside, as well as the harmony of the acoustics, so that the violin produced is not only beautiful in appearance and easy to play, but more importantly, it has a beautiful and touching timbre, loud and full dynamics, a very penetrating volume and a quality of control of intonation and frustration. This is the violin. ”

"At the same time, the violin is made up of more than 30 parts. Its main components include headstock, body, neck, pins, strings, horses, cheek rests, bows, panels, side plates, sound columns, etc. The violin has four strings, divided into: 1 string (E string), 2 strings (A string), 3 strings (D string) and 4 strings (G string). The violin body (resonance box) is about 35.5 cm long and is made of curved tops, backplates, and side plates bonded together. The panels are often made of spruce and have a softer texture, while the back and side panels are made of maple and have a harder texture. Whole maple for headstock and neck, and ebony for fretboard. The sound quality of a violin is basically determined by its wood and the corresponding structure, on the frequency of the wood's vibration and how it reacts to the vibration of the strings. A high-quality piano is able to transmit the fundamental and overtones of each sound with equal sensitivity. ”

"The violin has four strings, all of which were originally bare strings made of sheep's intestines, and from about the 18th century, the bass G string is often wrapped with silver wire, making it responsive. In modern times, the G, D, and A3 strings are wound with metal wire or steel wire, and more recently, nylon strings are also used. The E string was changed to a steel wire string to give it a better tone in the high register. ”

"The violin is made in a modern style, not entirely from the beauty of the form, but from the need for sound and performance. The violin top and back plate have a curved shape to make it resonate well and the sound is loud, the waist is narrow to facilitate the playing of high and low strings, and the top and back plate are equipped with inlays to prevent the wood from cracking, and also play a certain role in the sound quality of the instrument. There is a column support between the top and the backplate, and its position change has a significant effect on the timbre of the violin. The lower left side of the panel is glued with a bass beam, which not only plays a reinforcing role, but also has an acoustic role. ”

"If the paint on the surface of a violin is too hard, too soft, or unevenly painted, it will detract from the sound quality. When the bow rubs against the strings to vibrate the strings, the panel vibrates through the horse, and the back plate vibrates through the sound column, the E string vibrates less, while the G string vibrates more, so that the bass beam has greater vibration and causes the resonance box to vibrate. The ability to get the most out of the sound depends on the strings and their tension, the quality of the horse, the pressure and speed of the bow. In order to express the various sound qualities of the piano, it is necessary to add the player's bowing, fingering, kneading, and playing skills. ”

At the same time, in terms of artistic value and social influence, the violin is the most important instrument among Western musical instruments. It has played its most important artistic role in Western symphony orchestras (also known as "orchestras") and Chinese orchestras that combine Chinese and Western orchestras, as well as in solo and concerto performances. In the symphony orchestra, there is the name of the principal, the "principal", the first, so the principal violin is also called the "first violin". In the Western symphony orchestra, the violin obviously occupies an important position, and if it is the principal violin, it will also play the artistic role of the leader and leader. ”

Li Youyang's words were sprinkled, first introduced the cello, and then introduced the violin, then stopped his voice and looked at the daughters of the Dream Angel Dance Troupe who were sitting in two rows with Li Yiyi and them in front of him, and the girls all looked at him with admiration, thinking that Li Youyang not only wrote songs well, but also had such profound knowledge.

Or, if he doesn't write songs, doesn't sing, or simply becomes a teacher, he should be able to achieve very proud achievements!

And this is not only the voice of the girls of the Dream Angel Dance Troupe, but also the voice of Ji Ruolin, who has just entered the door, after hearing it.

Because, in this situation, anyone can see that Li Youyang is training as a teacher, aside from Li Yiyi, Chen Ying, Dong Xueqin, and Xiahou Yaoyao, for the standard students of Cannes Quyi Academy, including Du Shasha, Nie Yudan and Dianya Dream Dance Troupe!

And the content of the training is cello and violin that people don't know at a glance!

"So, next, you have to follow Dong Dong and Dandan, divide into two groups, and learn the relevant skills of cello and violin as soon as possible, because your performance on these two instruments will directly determine whether the theme song I wrote for the IMCS league can reach the most perfect state!"

"In addition, Yaoyao, I will prepare a few folk songs next, of course, I will also prepare a few Chinese style, but how can you also be the former queen of folk songs, especially at the IMCS All-Star Folk Song Night, how can you just sing Chinese style and not traditional folk songs?"

"It's okay, Li Youyang, if Xiahou Yaoyao doesn't want to sing folk songs anymore, I'll sing it, I will do it! Without waiting for Xiahou Yaoyao to express her position, Dong Xueqin took the initiative to ask for help. (To be continued.) )
