"Reveille" follows the bugle scale in the order of the notes C, G, C, E and G in C major. The United States Army maintains public access to the sheet music for "Reveille," a very short bugle or trumpet piece used to call soldiers to morning attention. Trumpet and bugle players can study the sheet music and listen to a recording on the U.S. Army Music website.
"Reveille" is also used by some scouting organizations such as the U.S. Scouts. It is used for the same purpose, rousing scouts from their beds and calling them to assembly.
"Reveille" has a short, repetitive structure designed to help wake people up by constantly starting and re-starting the assault of sound. In this way, it helps to create order in a camp.
