The Kent bugle (keyed bugle) is a keyed bugle introduced or possibly invented by the bandmaster of an Irish regiment, James Halliday, about 1810 and so named in respect of the Duke of Kent (Edward Augustus), the father of the then Queen Victoria. The kent bugle has six finger keys or stops, by means of which the performer can play upon every key in the musical scale. The kent bugle was popular until about 1860 when it was superseded by the cornet-a-piston. Research Kent Bugle
