I was fortunate to get to blow a vuvuzela which my teacher Mrs Sigamoney brought back from South Africa. I was interested to know more about the vuvuzela so I read about it.
The vuvuzela is also known as lepatata and it is a Tswana name. It is typically a 65-centimetre (2 ft) plastic device that requires the flow of air to produce a loud monotone note. A similar device, known as the corneta is used in Brazil and other Latin American countries. Many types of vuvuzelas are made by several manufacturers, may produce varying intensity and frequency outputs. The intensity of these outputs depends on the blowing technique and pressure exerted.
