The clarinet as we know it today was invented in the 18th century.
The clarinet is made of ebony, coconut wood, ebonite resin, metal or plastic. It has a very wide and adjustable range, and it first appeared in a symphony orchestra at the end of the 18th century.
The tone of the clarinet is very rich in the low register and very clear in the middle register. It can sound like a flute at times, especially in the high register.
Clarinets are categorized as follows: E-flat soprano clarinet, A clarinet, B-flat clarinet, E-flat alto clarinet, and B-flat bass clarinet.
