Title music refers to a kind of instrumental music that summarizes the central content of the music. It is often based on literature, drama, history, fairy tales, folklore and real life. Title music has a long history in our country, such as the guqin piece "Goose Falling on the Sand", the pipa piece "Ambush from Flying Daggers", the instrumental solo "Three Plum Blossom Lanes", the ethnic orchestral piece "Spring River Flowers and Moonlight Night", the wind and percussion piece "Hundred Birds in the Morning" Phoenix" etc. Most of the modern works are title music, such as the Erhu solo "Er Fountain Reflects the Moon", the violin concerto "Liang Shanbo and Zhu Yingtai", etc. Generally speaking, it is easier to understand when listening to title music because the title serves as a guide.

Non-title music is also called "absolute music" and "pure music". It does not use a title to indicate the content of the work, but only uses names such as musical form, genre, key speed, etc. to name it, such as "Symphony in a Major", "Concerto in Minor", "Sonata in E Major", etc. The content of these works must be understood by the viewers themselves.
