Origins and the old school

Although widely considered a synonym for rap music, the term hip-hop refers to a complex culture comprising four elements: deejaying, or “turntabling”; rapping, also known as “MCing” or “rhyming”; graffiti painting, also known as “graf” or “writing”; and “B-boying,” which encompasses hip-hop dance, style, and attitude, along with the sort of virile body language that philosopher Cornel West described as “postural semantics.” (A fifth element, “knowledge of self/consciousness,” is sometimes added to the list of hip-hop elements, particularly by socially conscious hip-hop artists and scholars.) Hip-hop originated in the predominantly African American economically depressed South Bronx section of New York City in the late 1970s. As the hip-hop movement began at society’s margins, its origins are shrouded in myth, enigma, and obfuscation.

Graffiti and break dancing, the aspects of the culture that first caught public attention, had the least lasting effect. Reputedly, the graffiti movement was started about 1972 by a Greek American teenager who signed, or “tagged,” Taki 183 (his name and street, 183rd Street) on walls throughout the New York City subway system. By 1975 youths in the Bronx, Queens, and Brooklyn were stealing into train yards under cover of darkness to spray-paint colourful mural-size renderings of their names, imagery from underground comics and television, and even Andy Warhol-like Campbell’s soup cans onto the sides of subway cars. Soon, influential art dealers in the United States, Europe, and Japan were displaying graffiti in major galleries. New York City’s Metropolitan Transit Authority responded with dogs, barbed-wire fences, paint-removing acid baths, and undercover police squads.
