Clarinet, also called clarinet, is a reed instrument with a wide range. Its roots can be traced back to the horn and bagpipes, and it is generally believed that it evolved from a single reed instrument like a clarinet-reed flute. The modern clarinet was invented by the German flute producer John Danner in 1690, and was improved many times after that, and finally finalized by the German flute player theobald Bohm.

Besides B-flat clarinet, E-flat clarinet and tenor clarinet, Bassett clarinet, bass clarinet and bass clarinet are commonly used. Traditionally, clarinets are made of wood. Elegant clarinets used to be made of ivory, but now they are generally made of plastic.

Clarinet is very flexible, it can easily play long notes across multiple scales, and it is famous for its continuous arpeggios, which is very expressive for soloists. Mozart was the first composer to use clarinet in symphonies. He thinks it is the closest instrument to human voice.
