The question raised by the poster seems to be non-specific.

In general, music that only has people playing but no one singing is collectively called instrumental music.

But its classification is very broad. According to the type, it can generally be divided into: folk music (that is, the performance of traditional Chinese musical instruments), and Western instrumental music (the performance of Western musical instruments).

Folk music is generally divided into solo and ensemble. For example, pieces like Erquan Yingyue and Horse Racing are (erhu) solos. I believe you have heard of the Twelve Girls Band, which is basically a modern version of the folk music ensemble.

The performance methods and classifications of Western instrumental music are quite extensive. Not only are the types of musical instruments diverse, but the forms of playing are also varied.

A Western musical instrument can be played in several ways. For example, a violin can be played as a solo (serenade), concerto (Butterfly Lovers), or ensemble (Canon String Quartet in D major). . and so on. These are considered classical forms of Western musical instrument performance.

Besides, Western musical instruments are also classified into playing styles, such as rock music, jazz music, and blues that are derived from modern styles. . There are also some non-mainstream ones that are popular outside (maybe they are out of date for me) and so on. Lots of variety. There’s endless variety!

I don’t know what kind of music the poster is hearing? Modern or classic? What kind of instrument was it played on? I don't know. I personally studied music and it has been several years since I graduated. I just gave a brief introduction to some music knowledge that I have learned before.

If the poster wants to learn more about music expertise, I suggest you refer to Baidu’s encyclopedia! Or read some related books!

Haha, I’ve said so much, do you think it’s okay?
