How to identify handmade violins? What are the tricks?

The choice of violin needs more care. Handmade violins are very different from ordinary violins. I'll tell you how to identify a handmade violin. Welcome to read!

The method of identifying handmade violin 1. Look at the wood, the panel is spruce, and the texture should be even and straight. The wood rays on the back plate should be straight. The pattern of the back plate is only beautiful, and it is not the beauty of the texture that affects the sound quality. It is important to look at the timbre, but what you hear is what you believe. And a good material, the pianist is reluctant to put it in a hot-pressing mold to press it out.

2。 Looking at the edge of the piano, because most of the factory pianos use hot-pressing molds to suppress the deformation of the wood grain on the edge of the piano, some handmade pianos generally see the round wood grain from inlay to the edge of the piano similar to relief, but the factory piano can not achieve this effect due to production relations.

3。 Look at the piano head. The exquisite craftsmanship of the piano head shows that the piano is largely hand-made. First of all, the piano head should be symmetrical, carved cleanly, and the details should be fine, such as? Comma? Start and spin down the gap.

4。 Looking at the accessories, the so-called good horse with good saddle, the real handmade piano should be made by the same pianist from beginning to end. Ensure coordination. Some pianos refer to handmade pianos. But one person makes the panel and one person makes the backboard. However, it was later spliced together, so it was semi-manual.

How to choose violin materials

The material of violin is divided into back plate, side plate and neck. Each kind of wood has a different sound, such as spruce as a panel, ebony as a fingerboard and so on.

Set age

Wood has its own age and time, and so do the rings. It is best to choose wood with uniform density, compact fiber structure and no knots.

In fact, the styles are almost the same, mainly reflected in the length, width, pattern and design style.

The production technology of violin is quite high. If the rough assembly is mostly made by machinery, the price is generally lower and cheaper.

Good violins are all made by hand, but pay attention to lines, smooth edges and corners, flatness and so on.

The string horse is a very delicate accessory on the violin. There are many materials of this accessory, which directly affect the sound quality of the piano.

Judging the quality of violin timbre volume: the sound is loud and clear, of course, it is obtained through the correct playing method. You can try to play according to the height of the piano, especially the G and D strings. If the sound played in a high position can be soft and loud, it shows that the pronunciation of the piano is ideal. On the other hand, if there is a harsh squeak, it means that there is something wrong with the placement of accessories, and even ordinary violins can't have obvious noise.

These four strings are pronounced evenly. In the range of violin, the intensity of various frequencies should be uniform or relatively uniform, and one tone should not be particularly strong and the other tones should be particularly weak. In particular, the low-frequency sounds on the G and D strings are louder. The minimum requirement should also be that there is no obvious difference between the four strings. Any piano with a loud and even pronunciation sounds very pleasant. Otherwise, if the pronunciation is too weak or the strength is very different, it will sound unpleasant or harsh.

Timbre: The timbre of violins varies greatly due to different materials, methods, sizes, strings, pigments and assembly. Advanced violins must have pure and soft high notes, full and powerful low notes, and implicit and concentrated pronunciation. Specific to each string, E string is required to be clear and bright, A string is as soft as a song, D string is elegant, and G string is rich and deep. In this way, the piano sounds mellow and beautiful without any noise.

Harmony: The fifth tone of each violin must be harmonious and can't be different, and it can't be obviously different from ordinary violins. In addition, the four strings of the violin are required to be sensitive in pronunciation, fast in vibration transmission and not dull. And the vibration lasts for a long time and decays slowly. If you are not familiar with the above identification methods, you can also choose the most convenient comparison method.

Judging from the working materials of violin, the quality of working materials is used to help judge the quality of violin.

If you are familiar with computers, you can judge from the spectrum analysis of violin sound.

Pitch is the lowest spectral line, and the pitch of the strings is determined by it. The spectral line above is overtone.
