The Rouse and Reveille are bugle calls played to signify different parts of the day.
The Rouse is the call used in conjunction with the last post at commemorative services, dedication services, and military funerals. The Rouse is a short bugle call that was also used to call soldiers to their duties.
After the one minute silence, the Rouse is sounded during which flags are raised from half-mast to the masthead.
Reveille, from the French word ‘reveillez’ meaning to ‘wake-up’, was originally played as a drum beat just prior to daybreak.
Its purpose was to wake up sleeping soldiers and to let sentries know that they could cease challenging. It was also a signal to open the town gates and let out the horse guard, allowing them to do a reconnaissance of the immediate area beyond the walls.
Today, the Reveille is only performed at Dawn Services or as the first call of the day in Barracks.
