The vuvuzela (English pronunciation: /vuːvuːˈzeɪlə/, also known as lepatata (its Tswana name), stadium horn and plastic trumpet, is a typical 65 cm (2 ft) plastic blowing horn that produces a loud, distinctive monotone B♭3 note (the B♭ below middle C). A similar instrument, known as the corneta, is used in Brazil and other Latin American countries. Many types of vuvuzela, made by several manufacturers, may produce varying intensity and frequency outputs.[1] The intensity of these outputs depends on the blowing technique and pressure exerted.[1]
