The pocket trumpet is an ancient musical instrument that originated in Europe and has a history of thousands of years. In the Bronze Age, people learned to use metal to make musical instruments similar in shape to animal horns, and used them in combat, hunting, and sacrifice. The horn used in ancient hunting can be said to be the originator of the trumpet.

The pocket trumpet consists of a mouthpiece, a tube body, and a mechanical part. The mechanical part is composed of a piston and a piston sleeve.
Voice method of pocket trumpet:
Put your lips close to the mouthpiece, and use the vibration of the lips to drive the air in the tube to make a sound. The pronunciation of the pocket trumpet consists of three parts: airflow, pronunciation body, and resonance body. Airflow is the driving force for trumpet pronunciation. The airflow exhaled from the human respiratory organs has different flow rates and different speeds.
The position of the pocket trumpet in the wind family:
The position of the pocket trumpet in wind music is very important, because the trumpet is mainly responsible for the melody part in the brass part, and it plays a leading role. The rhythm part is mainly in charge of the trombone, French horn, and tuba. The band is a whole. Although the trumpet is more important in the melody part, whether a piece of work can be performed perfectly depends on whether the melody, rhythm, harmony and other aspects can be perfectly matched.
