The clarinet is a type of wind instrument, usually made of African black wood, so called black pipe, clarinet, and is one of the most widely used instruments in the wind instrument family, known as an "orator" in the orchestra and a dramatic soprano in the pipes. The clarinet consists of flute head, small tube (also known as "two sections"), main pipe (two sections, namely upper and lower joints), horn mouth and mechanical sound key system.
