The common instruments in the brass family are used in orchestras, concert bands, brass bands, jazz bands and other instrumental ensembles. The main instruments in the brass family (Trumpet, Trombone, French Horn, Euphonium, Tuba) can be taught from year 3 onwards, other than Tuba being more suitable to older (year 5-6) students due to its size. Trombones have a physical limitation because some notes are difficult to reach for children with shorter arms, but teaching methods and repertoire are able to work around this.
Trumpet and Trombone are standard in jazz ensembles; Trumpet, Trombone, French Horn and Tuba are standard in orchestras.
There are a number of other brass instruments used in Brass Bands, such as cornet, tenor horn and baritone horn. These are not standard instruments in some other ensembles but they are very close to other instruments in the family (eg. Trumpet/Cornet) and musicians can often transition between them without much trouble.
