A bugle is a brass instrument that is similar to a TRUMPET, but with a more limited range of notes. It is often used in military and scouting contexts, and is most commonly associated with the playing of 'Taps' at funerals. The term 'bugle' can also refer to a type of HORN, which is a wind instrument made from an animal HORN, usually an ELK. The term 'tantaras' is also related to bugles, as it is a type of fanfare or call that is played on a bugle. Finally, the term 'RETREAT' is associated with bugles, as it is a bugle call that signals the end of the day.
