What is the difference between country music and bluegrass music? What are their characteristics?

Bluegrass music is a kind of exquisite, pure and original music, which is easy to identify. Compromise music has two or three harmonies, with intense rhythm and unrestrained emotions.

Country music is developed from European folk songs brought by the first generation of American immigrants. It can be divided into many equally important schools, such as cowboy music, western swing, bluegrass music and so on, and has developed its own unique personality on the original basis. It abandons the tradition of oral narration of folk songs, and often uses the melody played by instrumental music to express inner feelings. Country singers have a strong nasal voice when singing, and more and more emphasis is placed on the musician's own personality when playing musical instruments.
