Kwaito is a music genre that emerge in Johannesburg, South Africa in the early 1990s. It is based on house music beats, but typically at a slower tempo and containing melodic and percussive African samples which are looped, deep basslines and often vocals, generally male, shouted or chanted rather than sung or rapped. DJ Diplo described kwaito as "[poor South African kids'] form of slowed-down garage music." More recently, kwaito artists like Zola have rapped their lyrics in a hip-hop style, while others such as BOP and Oskido have sped up their beats and toned down the male chants to create a softer form of kwaito or african house. Other prominent kwaito artists include Arthur, Mandoza and Mzekezeke. Kwaito's lyrics are usually in indigenous South African languages or in English, although several languages can be found in the same song. The name kwaito itself is derived from the Afrikaans word Kwaai, meaning "angry". This Afrikaans word is derived from the Isicamtho, South African township slang, word amakwaitosi, meaning "gangster". Arthur Mafokate, one of the founding fathers of kwaito describes the relationship between kwaito and "gangster" being because it is "all about the ghetto music". Kwaito was born in Soweto, one of the townships where blacks were forced to live during the time of apartheid. Similarly, kwaito has been referred to as the "sound of the ghetto", and emerged from the most economically depressed areas of South Africa. Therefore, kwaito "opened up an economic avenue for a lot of young people as well as a creative avenue". Older musicians looked down upon this new music, calling it the music of gangsters, while current kwaito musicians tended to interpret this relationship of the word "gangster" to their music as it being "hot and kicking". Other listeners describe kwaito as “a mixture of all that 1990’s South African youth grew up on: South African disco music, hip hop, R&B, Ragga, and a heavy, heavy dose of American and British house music.”
