Erhu, the shining star in the long river of Chinese history, is unique and full of profound cultural heritage, like a poet who sings in a low voice, telling ancient stories and is deeply loved by people. Today, let's unveil its mystery and discover the mystery behind that beautiful sound. 
Since the Tang Dynasty in the 7th century, the erhu has begun to emerge. After years of baptism, it has gradually become a bright star in China's traditional musical instruments, playing an indispensable role in classical, folk and various stage performances. So, where does this spring-like sound come from?The answer lies in the vibration of the strings. 
Stringed instruments are able to be pronounced because of the vibration of the strings. The frequency and amplitude of the vibration of the strings determine the pitch and loudness of the tone. When the erhu is played, the strings begin to vibrate as the bow hairs slide over the strings. The sound waves produced by this vibration are the beautiful melodies we hear. The strings of the erhu are the key to sound. The choice of texture and material determines the vibrating performance of the strings. The strings of the erhu are usually made of metal wire, such as shiny steel wire or hard-textured copper wire. These materials have good vibration properties and can easily cause string resonance. When the bow hair squeezes the strings, the vibration of the strings is further stimulated, producing a louder and clearer sound, adding rich color to the expressiveness of the instrument. 
* Through exquisite performance skills, the musicians finely control the sound quality and volume of the erhu, and interpret the emotional connotation of the work to the fullest. With their profound skills and skills, they perfectly present the charm of erhu. Therefore, learning and appreciating erhu art is not only an auditory enjoyment, but also a process of gaining an in-depth understanding of traditional Chinese culture. 
The beautiful movement of the erhu stems from the use of natural materials, the ingenious sound design, and the exquisite interpretation of countless outstanding artists. It is a treasure of Chinese culture, which is worthy of our cherishing, inheritance and carrying forward.
