Principle: When playing, the airflow slides over the mouthpiece and hits the inner tube wall on the opposite side. The airflow vibrates in the inner cavity of the sound tube, producing musical sounds. Due to the different positions of the beeswax and cork, the airflow The vibration periods in the sound tube are different, so the vibration frequencies of the airflow are different, thus producing different musical sounds.

In the eight-tone classification of ancient musical instruments, panpipes are classified as bamboo instruments. It consists of arranging bamboo tubes of different lengths in a row, braiding them with ropes, bamboo grates or setting them up with wooden frames.
