Brass instruments are those instruments that use air flow and player's mouth vibration in order to produce sound, like for example trumpet, saxophone or conch. Important thing is that we also have wind instruments like flute, the difference is that in those kind of instruments lips-vibration does not matter. The same goes for church organ for example which as well need air flow to operate but use keyboard and nobody needs to blow into them.
