The trumpet or cornet is the smallest and highest member of the brass family. As with all brass instruments, the sound is produced by buzzing the lips into a mouthpiece. The difference between a trumpet and cornet is very minor. They both play the same notes and they sound virtually the same. In appearance, the trumpet looks a bit longer and more slender than a cornet. The real difference has to do with the way the tubing of the instrument flares. A cornet is more cone shaped or conical than a trumpet. For all practical purposes they are the same instrument for beginners. A band teacher may refer to the trumpet section when he or she really means all trumpets and cornets. Either is a good instrument for a beginner.
