National musical instruments are divided into four categories: body-sounding instruments, membrane-sounding instruments, air-sounding instruments, and string-sounding instruments. Chinese national musical instruments have a long history and a long history. Only from the unearthed cultural relics can be confirmed: as far back as the pre-Qin period, there were a variety of musical instruments. Such as the bone unearthed in Hemudu, Zhejiang, the cultural site of the Neolithic Age, the Jiahu bone flute in Wuyang County, Henan (the earliest flute was about 8,000 years ago), the Xun unearthed in Banpo Village, Xi’an, the Yangshao Cultural Site, and the stone unearthed in Yin Ruins, Anyang, Henan Chime, wood-tuned python skin drum; chimes, chimes, hanging drums, jian drums, flannel drums, pan flutes, sheng, chi, se, etc. unearthed from the tomb of Marquis Yi of Zeng, Suixian County, Hubei (burial in 433 BC). Stringed instruments are an important branch of the musical instrument family. In classical music and even modern light music, almost all lyrical melodies are played by stringed parts. It can be seen that softness and sound are the common characteristics of all stringed instruments. The timbre of the stringed instruments is unified, with multiple levels of expressiveness: surging and exciting in ensemble, gentle and graceful in solo; and flexible colors due to the rich and varied bowing techniques (vibration, breaking, plucking, jumping, etc.). The pronunciation method of stringed instruments relies on mechanical force to vibrate the tensioned strings, so the pronunciation volume is limited to a certain extent. Stringed instruments usually use different strings to play different notes, and sometimes you need to use your fingers to press the strings to change the length of the strings, so as to achieve the purpose of changing the pitch. In terms of their pronunciation, stringed instruments are mainly divided into bowed stringed instruments (such as violins) and plucked stringed instruments (such as guitars).
