Firstly, the shape of the head inserted with a wooden stick is a double spring head. Generally, the head is thick and has a silver or leather hoop. It is a single spring (currently, it seems that due to the high level of leather hoop B, silver has not been seen in high-end music concerts in recent years). Thin is a double spring. Fat is a single spring. Large is a single spring. Small is a single spring. There is a silver ring between the double spring and the button. Single springs do not have a double spring... (because single springs have an extra section)

Generally speaking, the solo that you hear in classical music that is closer to the melody for a longer period of time and is played for other parts to unfold is definitely the double reed... For example, the Spring Festival overture is quite long... The Beijing good news to the border village is quite long... Oh, I can't remember anything else. The double reed is basically my own son. Which capital has him for a long period of time? When watching the performance, he shakes vigorously like a suona, and when he performs solo, his movements are so big that he almost stands up. He must be holding back and blushing all over his face... (Ah, my personal preference is so obvious) The solo that is different from the melody and sounds strange or is about to end. At that time, the solo was a single reed

Here are a few easy to find ones, such as the middle and back sections of Yao dance music, which have a rather eerie solo. For example, there is a strange solo in front of the Red Flag Song fast-paced board and behind the trumpet. For example, there is a very melodious solo at the end of the morning song by Pilgit, and the last section of the first movement by Bei Liu. If you can't continue listening to these, listen to Chen Qizhen. Let's open the slightly cool wind and listen to the prelude three times. You will remember that the double reed is small and difficult to play. In the first class, you may not even be able to make a sound, and the sound is a bit sharp, like singing with a clear and organized voice. Due to the characteristics of its structure (and price), the pitch is relatively less affected by the temperature of the instrument and it is difficult to tune it up significantly... Therefore, he plays the A in the counterpoint stage of all concerts
