China Qin Trio is a bundle for three famous Qin instruments in Chinese Music. They are Guzheng, Qin and Yangqin.
The zheng or Guzheng, also known as a Chinese zither, is a Chinese plucked string instrument with a more than 2,500-year history. The modern guzheng commonly has 21 strings, is 64 inches (1.6 m) long, and is tuned in a major pentatonic scale. It has a large, resonant soundboard made from Paulownia. Other components are often made from other woods for structural or decorative reasons. Guzheng players often wear fingerpicks made from materials such as plastic, resin, tortoiseshell, or ivory on one or both hands.
Guqin is a plucked seven-string Chinese musical instrument. It has been played since ancient times, and has traditionally been favoured by scholars and literati as an instrument of great subtlety and refinement, as highlighted by the quote "a gentleman does not part with his qin or se without good reason, "as well as being associated with the ancient Chinese philosopher Confucius. It is sometimes referred to by the Chinese as "the father of Chinese music" or "the instrument of the sages". The guqin is not to be confused with the guzheng, another Chinese long zither also without frets, but with moveable bridges under each string.
The trapezoidal Yangqin is a Chinese hammered dulcimer, derived from the Iranian santur. It used to be written with the characters 洋琴 (lit. "foreign zither"), but over time the first character changed to 揚 (also pronounced "yáng"), which means "acclaimed". It is also spelled yang quin or yang ch'in. Hammered dulcimers of various types are now very popular not only in China, but also Eastern Europe, the Middle East, India, Iran, and Pakistan. The instruments are also sometimes known by the names "santoor" and "cymbalom". This instrument had an influence on the Thai classical instrument, known as Khim.
