Extended data

Ragtime music, especially the popular style of downplaying jazz, is aimed at the middle class and is not liked by orthodox musicians.

Jazz first appeared at the end of19th century, but it was not called "jazz" at that time. It was originally called Jass, and it first appeared in the black workers' residential areas in southern American cities.

Like ragtime music, jazz first appeared as dance music.

By about 19 12, the instruments of a typical jazz band include cornet (or trumpet), trombone, clarinet, guitar, double bass and drums.

Jazz gives the impression that banjo and tuba stand out from the crowd. In fact, it took several years for jazz bands to start using it, because the early recording technology could not connect softer guitars and bass.

In the jazz band at that time, the trumpet was the lead singer, and the trombone echoed it in the bass area in a sliding way, and the clarinet played a decorative role in both.
