Names of the different parts of the instrument are presented here. The aim is to understand what “beginning of the bell” or other terms are describing in the articles on this website.

The most important
By unrolling the tubes, similar shapes appear. This is how we can identify easily brass subfamilies.
- At the top: Trumpet and Trombone family which is the closest to cylindrical tubes.
- In the middle: saxhorns family which includes the flugelhorn.
- At the bottom: tubas family which if the most cylindrical.
The French horn family is similar to the trumpet family with a much longer cylindrical part and a more flared bell.
Cornets are not represented either. They would fit between the two first schemes.
The lead pipe is represented as a conical tube but it’s not always right. Valves trumpets are exception for example.
Cylindrical parts of tubas are not represented but slides could not exist without some of these.
This disassembled trumpet allows us to see clearly the different parts of the instrument.
