A bugle call is a short tune, originating as a military signal announcing scheduled and certain non-scheduled events on a military installation, battlefield, or ship. Historically, bugles, drums, and other loud musical instruments were used for clear communication in the noise and confusion of a battlefield. Naval bugle calls were also used to command the crew of many warships.
A French Marine plays the bugle during the Gulf War, in March 1991.
