A Dictionary of Music and Musicians/Kent Bugle
KENT BUGLE, or Royal Kent bugle, an improvement of the Key bugle, said to have been named in consequence of a performance upon it before H.R.H. the Duke of Kent by Halliday in Dublin, shortly after its invention. It had a complete chromatic scale from B♭ below the treble stave to C above, but is now superseded by valve instruments.
