How the Keyed bugle makes its sound

In the Hornbostel–Sachs system, which classifies instruments by how they produce sound, the Keyed bugle belongs to the brass (lip-vibrated aerophones): the player's buzzing lips set the air column vibrating – trumpets, horns, trombones, tubas and the didgeridoo.

More broadly it is one of the aerophones (wind instruments), where sound comes from vibrating air.

Players shape its sound through technique and materials; the resonating body filters the raw vibration, boosting some harmonics and damping others.

From Wikipedia

The keyed bugle (also Royal Kent bugle, or Kent bugle) is a high-pitched brass instrument with a wide conical bore and tone holes operated by keys to alter the pitch and provide a full chromatic scale. It was developed from the bugle around the year 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. It was superseded by the flugelhorn and cornet after the invention of valves.
