A bugle is a simple brass musical instrument that produces sound by the player's lips vibrating against the mouthpiece. It has a conical shape and typically lacks valves, making it easy to play. Bugles are often used in military settings for signaling and ceremonial purposes, as they can produce clear, loud notes that carry over long distances. The bugle is closely associated with military traditions, where it is used to convey commands and announcements. It is also a popular instrument in marching bands and is sometimes featured in orchestras. The sound of a bugle can evoke a sense of nostalgia and patriotism, often linked to historical events and ceremonies.
