Keyed bugle (USA) [key bugle, Kent bugle, Royal Kent bugle, Kent horn]
- Ralph T. Dudgeon
A conical military bugle with tone-holes controlled by keys similar to those found on woodwind instruments. The instrument was the first fully chromatic soprano brass voice in bands in Europe and the United States. The first keyed bugles had five keys; seven keys made the instrument fully chromatic. Extra keys on later instruments increased alternate fingerings and extended the low range. American keyed bugles were commonly pitched in C, with a crook to B♭, and provided the alto and soprano voices in brass bands, with the bandleader often playing a high E♭ model. Elaborate keyed bugles with up to 12 keys were presented to outstanding bandmasters and soloists. Keyed bugles were normally made of copper with brass or German silver keys and fittings, but some were made of solid silver, gold, and tortoise-shell....
