The trumpet is a great instrument to learn as it is relatively inexpensive, very portable, and stylistically very flexible. trumpets are used in bands, orchestra, jazz big bands and other ensembles, chamber music (brass quartets and quintets), show orchestras, pep bands, rock bands, Latin music ensembles, New Orleans brass bands ("jazz funeral" bands), and many others. As with other wind instruments, the trumpet relies on you connecting your breath to your sound, which can be difficult to begin with (and produces some strange sounds) but is very much worth pursuing.
