The keyed bugle (also Royal Kent bugle, or Kent bugle) is a wide conical bore brass instrument with tone holes operated by keys to alter the pitch and provide a full chromatic scale. It was developed from the bugle around 1800 and was popular in military bands in Europe and the United States in the early 19th century, and in Britain as late as the 1850s.
