The coordinate surfaces of the Cartesian coordinates (x, y, z). The z-axis is vertical and the x-axis is highlighted in green. Thus, the red plane shows the points with x = 1, the blue plane shows the points with z = 1, and the yellow plane shows the points with y = â1.
Generally speaking, rap was started in the Bronx, New York in the 1970âs. Because of personal recollections and the myth-making aspect of hip hop, itâs hard to isolate the exact time and place where rap started or who exactly should be considered the inventor of rap.
Rapping is also used in Kwaito music, a genre that originated in Johannesburg, South Africa, and is composed of hip-hop elements. Another form of rap that predates hip hop was boxer Muhammad Ali's rhythmic poetry used to taunt his opponents in the 1960s and 1970s, or Gil Scott-Heron's melismatic style.
