Woodwind instruments include flute, piccolo, oboe, clarinet, saxophone, row shaw and bass. They all have a hollow tube that can blow out air. Woodwind instruments got their name because they were originally made of wood, but now many woodwind instruments are also made of metal and plastic. Woodwind instruments have a long history. Basically, the primitive flute made by ancient humans in the leg bones of animals is the ancestor of woodwind instruments. Modern woodwind instruments are developed from instruments such as reed, flute and xiao used in folk music in various countries.

The woodwind instrument has a sound hole on the pipe body, and changes the effective length of the pipe body by blocking and releasing a specific sound hole to produce different pitches.
