Recall (bugle call)

"Recall" is a bugle call used to signal to soldiers that duties or drills are to cease,[1] or to indicate that a period of relaxation should end.

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, a requirement if it is to be playable on a bugle, or on a trumpet without moving the valves.
