The eb clarinet is a type of woodwind instrument, usually made of African black wood. It is made of wood, hard rubber or metal. It has a beak-shaped mouthpiece and a round hollow. The tube body is composed of five detachable tubes. The tube body is cylindrical, and the lower end is an open bell mouth. Fix a reed at the mouthpiece. When the player blows through the space between the reed and the mouthpiece, and with proper pressure from the lower lip, the thin reed tip vibrates, causing the air column in the instrument tube to vibrate, thus giving out a softness timbre. Its roots can be traced back to horns and bagpipes, and are generally believed to have evolved from the reed flute, a eb clarinet-like single reed instrument.

The eb clarinet is different from the oboe. The eb clarinet is a transposing instrument, the oboe is not a transposing instrument, and the oboe uses two reeds to make sound, and the eb clarinet uses a reed and flute to make a sound.

Pipe effective sound column principle pronunciation (overtone is 12 degrees).

As for the eb clarinet family, they are approximately cylindrical from beginning to end.
The pipes of the musical instrument are all made of wood and are divided into five sections. The reason for making five sections is entirely for the convenience of repairing and carrying. Because of the closed tube principle of the air column, the tube length is only half of the other wooden tubes.
