What are bagpipes made of?

Bagpipes, pronounced in Chinese: fēng dí, also known as wind bag pipes, are a folk musical instrument popular in European countries. Bagpipes belong to wind instruments, and their sound-making principle is similar to that of organ, accordion and even harmonica. They sound by vibrating reeds (embedded in wooden pipes) by airflow. Its pronunciation principle is that the player inflates the airbag and then presses the airflow in the airbag to the spring tube installed on the airbag for pronunciation.

The structure of Irish bagpipes (only this kind is found ~)

One end of the bagpipe bag is a big thick tube, which is connected with five thin tubes, and the other end of the bag is connected with a thin tube with air holes like a flute. The hand should change the notes by controlling the air holes of the thin tubes. It is generally believed that the earliest bagpipes in Ireland are very similar to the big bagpipes in the Scottish Highlands today. This ancient Irish bagpipe was named Irish battlefield bagpipe in 1920.
