Trumpet

a well known musical wind instrument. It is the type of a large family, including the bugle, horn, trombone, cornet, etc. The essential parts are a tube, cup-shaped for the mouth at one end and bell-shaped at the other. The tones are produced by the vibrations of the player's lips. The simple trumpet is straight; the cavalry trumpet is bent twice upon itself; the orchestral trumpet is fitted with a sliding section for changing the length of the tube. The addition of finger holes and valves increases the range of notes. The trumpet is the traditional instrument of war. Mars is represented in art as blowing the trumpet of war. Its peal is stirring and imperative, putting life into the feet and courage into the heart. The trumpet's call is the signal of advance, the signal of the wild charge. See Orchestra
