Reveille takes its name from the French word for wake up and has been used by militaries for generations as the sunrise bugle call signalling the start of the day. In the United States Army it is played during flag raising ceremonies in the morning. The melody spread far beyond barracks through films, cartoons and scout camps, becoming shorthand for an early start. In the mobile phone era it circulated widely as a built in ringtone, including on Sony Ericsson handsets, which helped keep it familiar online.
