Vuvuzela

The vuvuzela is a horn, with an inexpensive injection-molded plastic shell about 65 cm long, which produces a loud monotone note, typically around B♭ 3 (the first B♭ below middle C). 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.
