Reveille

"Reveille" (US: /ˈrɛvəli/ REV-ə-lee; UK: /rəˈvæli/ rə-VAL-ee) is a bugle call, trumpet call or pipes call most often associated with the military and prisons; it is chiefly used to wake military personnel and prisoners at sunrise. The name comes from réveille (or réveil), the French word for "wake up".

British Army Cavalry and Royal Horse Artillery regiments sound a call different from the infantry version shown below, known as "The Rouse" but often misnamed "Reveille", while the Scottish Regiments of the British Army sound a pipes call of the same name.
