Bugle

A bugle is a long, skinny musical instrument that is often used to play simple tunes like "Taps" or "Reveille." It looks kind of like a long trumpet, but instead of having buttons to change the sound, it only has one tube that you blow into and make sounds with your lips. It's often used by soldiers to signal different things, like to wake up in the morning or to signal the end of the day. So, a bugle is like a skinny trumpet that makes simple sounds and is used to signal things, especially by soldiers.
