History

Like other bugle calls, "recall" is a short tune that originated as a military signal announcing scheduled and certain non-scheduled events on a military installation, battlefield, or ship. Historically bugle calls indicated the change in daily routines of camp. A defining feature of a bugle call is that it consists only of notes from a single overtone series. This is in fact a requirement if it is to be playable on a bugle or equivalently on a trumpet without moving the valves.
