The trumpet is divided into several different musical instruments. One is a wind instrument, which is thin at the top and thick at the bottom. It is mostly made of copper. Wind instruments are thin at the top and thick at the bottom. The mouth at the bottom opens to amplify the sound.
There are many ways to classify trumpets. Generally speaking, they can be divided into hole blowing, single reed, double reed and lip spring. They are collectively called woodwind instruments, although many instruments have used metal, rubber and even synthetic materials as raw materials.
In orchestras and military bands, this group of instruments is called the wooden pipe group, while the lip spring air sounding instrument is called the copper pipe group.
