What's the name of this instrument?

There are many kinds of cloth, besides the traditional oval cloth, there are also many types of cloth, such as gourd cloth, grip cloth, mandarin duck cloth, mother-child cloth and so on.

Traditionally, it is mostly oval, but now there are many kinds, such as gourd, handle, mandarin duck, mother and son, etc., with beautiful style and fine technology.

1. Gourd bed: equipped with a throat device, shaped like a gourd. Production needs a second child, and the process is complicated. The place near the waist is the thinnest, and when the airflow passes, it can cause edge sound effect again, so that the high-pitched range of the trap can be appropriately expanded. Because the piano body is longer, it is more convenient and labor-saving to play, and the timbre is softer than the traditional oval.

Gourd awn is characterized by:

A. The range above the pitch (starting from full flat blowing) extends for three degrees; But the downward flow part below the pitch is reduced by three degrees;

B, save effort when playing high notes;

C due to the throat device, the timbre of the bass area is affected.

2. Grip method: It is the grip method of holding the performance, and it uses the roots of ten fingers and thumb to control the sound hole.

3. Yuanyang spectrum: refers to the binary spectrum with different pitches, opposite directions and connected bases. The two ends of this urn have a blowing hole, and the sound holes of the upper and lower urns are exactly the same as those of ordinary urns. You can quickly change when you play.

Yuanyang is characterized by rich timbre and wide range. But the shape is not beautiful (more abnormal than the original shape), and it is not convenient to switch between Yuanyang and Yuanyang when playing. Moreover, the sound quality changes greatly, so the sound quality is uneven.

4. Mother and child: refers to two conjoined shackles with different sizes and the same direction. The interval between the big shackles and the small shackles is generally pure five degrees. For example, the big one is G, and the small one is D. You can also combine them as you like.

5. Tau-head ring: According to the improvement of Ningxia Hui musical instrument, it has a hole of 10, ranging from bass 5 to treble 2, and has a sound insulation board inside, which is round and thick and easy to blow the treble. The disadvantage is that the hole is slightly larger and the scope is not easy to expand.

6. Bullet pad: Feng's latest patented product, ceramic pad, is made of double-cavity structure by imitating gourd pad inside, which is convenient for beginners to master at will and easy to blow high notes; The disadvantage is that it is not easy to blow down.

At present, most common on the market are gourd, bull's head, bullet and oval. Others are rare.
