19th century versions based on the original bugle included keys and valves. Keyed bugles were invented in England in the early 19th century, with a patent for one design, the Royal Kent bugle, taken out by Joseph Halliday in 1811. This bugle was highly popular and widely in use until around 1850 – for example, in works by Richard Willis, later bandmaster of the United States Military Academy Band at West Point. This version of the bugle stopped being used when the valved cornet was invented.
