Instrumental music includes: all types of string instruments, woodwind instruments, brass instruments and percussion instruments.

Instrumental music is music that is played entirely with instruments without the use of human voices or in a subordinate role to vocal music. The instruments played can include all kinds of string instruments, woodwind instruments, brass instruments and percussion instruments. Some instrumental music also uses part of the human voice as an effect.

Some composers sometimes add some vocals, such as the chorus of "Ode to Joy" in "Beethoven's Ninth Symphony", but in general symphonies are instrumental music rather than vocal music. In addition, whistles and humming performed by human voices are often added to instrumental music to add certain effects.

Of course, the creation and performance of purely instrumental music also has a long history. It is said in "Warring States Policy" that "Linzi is very prosperous and rich, and its people all play the yu, drums, zithers, build buildings, and play the harp." It shows how active the performance of folk instrumental music was at that time. The well-known story of Boya playing the drum and harp and meeting a close friend tells the story of Boya's superb playing, which Ziqi understood deeply.

One is good at playing and the other is good at listening, so the two become friends of life and death. During the Sui and Tang Dynasties, the pipa was one of the main instruments in the "Daqu" band. Pipa masters emerged one after another with superb skills and new tunes. Bai Juyi, a poet in the Tang Dynasty, gave a very vivid description of pipa music in his poem "Pipa Xing".

Blowed string instruments:

Blowed string instruments mainly refer to huqin-like instruments. Although its history is shorter than other ethnic instruments, due to its beautiful pronunciation, rich expressiveness, high performance skills and artistic level, stringed instruments are widely used in solos, ensembles, ensembles and accompaniments. Typical musical instruments: Erhu, banhu, Gehu, morinouqin, Aijie, Jinghu, Zhonghu and Gaohu.

Most stringed instruments have two strings, and a few have four strings, such as Sihu, Gehu, Aijie, etc. Most of the piano tubes are covered with snake skin, python skin, sheepskin, etc.; a few are made of wooden boards such as coconut palm, banhu, etc. A few are flat or oblate, such as morinouqin, penhuhu, banhu, etc. Some of their timbres are elegant and soft, some are clear and bright; some are vigorous, cheerful and full of singing.
