The first reason is that the piano is lighter and the support is not heavy.
Reason 2: When wearing a skirt or shorts, the solution to the smooth swing of the piano rest is to place a rough towel or woolen cloth under the piano rest to prevent slipping.
When we choose an erhu, the first thing to consider is the wood material of the body and the quality of the python skin, and then the workmanship. How to identify these things? There are many popular science articles on the Internet, and I also I have written some articles, and basically follow these popular science guidelines to ask the store and test them yourself. But there is actually a very unique problem that has been ignored by most Erhu popular science articles, but in fact this is the first thing our Erhu buyers notice when choosing Erhu, but it is just too common. Even buyers themselves often overlook this issue, which is the shape of the erhu itself.
Although many popular science writers and buyers have ignored this issue, erhu manufacturers generally have some ideas about this issue. Therefore, with the unremitting efforts of many experts and scientific performers, our erhu There are more and more types. Some of them are purely decorative and have no impact on the performance, while some of them actually have some impact on the pronunciation of the erhu.
Let’s first talk about decorations that have little impact on performance. If you are interested in collecting erhu, then this is also a very important consideration. In terms of decorative shape, there are mahogany curved neck erhu, Dragon head erhu, flat top erhu, etc. This year, after the Erhu master Mr. Chen Jun created the "Tai Chi Qin Xia" erhu concept, the Ruyi dragon head Tai Chi Hu appeared based on the erhu shape specially designed for his own playing. Many erhu collectors Try to collect all kinds of decorated erhus as much as possible. After all, the culture represented by the erhu, the wood of the erhu and the carving of the erhu decoration all have their own collection value.
Let’s talk about the factor that has a certain impact on the performance. The most influential factor is the barrel shape of the erhu. After years of continuous improvement and innovation, the barrel of the erhu has changed from the unified octagonal hexagonal shape at the beginning. There are many new varieties of erhu, such as flat cylinder, straight-sided egg-shaped cylinder and elliptical cylinder, as well as the whole-cylinder erhu that has applied for a national patent for its overall structure
Flat cylindrical erhu: The original hexagonal octagon was changed to an ellipsoid. In order to adapt to the structural changes, the skin method was also changed, the strings were thickened, and the piano rod was changed to an oval shape. The characteristic of this kind of erhu is that its volume is relatively loud.
Flat hexagonal/octagonal erhu: There are many categories of this kind of erhu. The basic principle is to make the regular hexagonal/octagonal erhu of the harp tube flatter and turn it into a symmetrical or irregular flat cylindrical shape. Compared with the traditional erhu, this type of erhu has many advantages. The volume is larger, the upper and lower positions are more balanced, and the pronunciation is sensitive enough. However, the disadvantage is that there are still some differences in timbre compared with the traditional erhu. Many people still feel uncomfortable listening to this erhu performance. Can't get used to it.
Full-tube erhu: Use wood to directly make the shape of the erhu without using splicing. This kind of erhu is supported by national patents and is a commercial originality. However, from the perspective of practical performance, the whole-tube erhu Compared with performance, its application value is actually limited. The reason why the whole-cylinder erhu appears is that hollow wood is mostly modified according to local conditions. It is very meaningful to avoid waste. However, regardless of whether the original wood is hollow or not, the craftsmanship of the entire erhu is very difficult and the workmanship must be exquisite, so it has a particularly high collection value.
