How To Use a Vuvuzela Horn - How To Blow a Vuvuzela/Stadium Horn
Vuvuzela music: Telemann Trumpet Concerto in D major, I: Adagio
The vuvuzela, also known as lepatata, is a plastic horn, about 65 centimetres (2 ft) long, which produces a loud monotone note, typically around B♭ 3. Some models are made in two parts to facilitate storage, and this design also allows pitch variation. Many types of vuvuzela, made by several manufacturers, may produce various intensity and frequency outputs. The intensity of these outputs depends on the blowing technique and pressure exerted.
