Who and what were the models for the development of the breaking?

Break dancing, also called breaking and B-boying, energetic form of dance, fashioned and popularized by African Americans and U.S. Latinos, that includes stylized footwork and athletic moves such as back spins or head spins. Break dancing originated in New York City during the late 1960s and early ’70s, incorporating moves from a variety of sources, including martial arts and gymnastics.

Break dancing is largely improvisational, without “standard” moves or steps. The emphasis is on energy, movement, creativity, humour, and an element of danger. It is meant to convey the rough world of the city streets from which it is said to have sprung. It is also associated with a particular style of dress that includes baggy pants or sweat suits, baseball caps worn sideways or backward, and sneakers (required because of the dangerous nature of many of the moves).

The term break refers to the particular rhythms and sounds produced by deejays by mixing sounds from records to produce a continuous dancing beat. The technique was pioneered by DJ Kool Herc (Clive Campbell), a Jamaican deejay in New York who mixed the percussion breaks from two identical records. By playing the breaks repeatedly and switching from one record to the other, Kool Herc created what he called “cutting breaks.” During his live performances at New York dance clubs, Kool Herc would shout, “B-boys go down!”—the signal for dancers to perform the gymnastic moves that are the hallmark of break dancing.

In the 1980s breaking reached a greater audience when it was adopted by mainstream artists such as Michael Jackson. Jackson’s moonwalk—a step that involved sliding backward and lifting the soles of the feet so that he appeared to be gliding or floating—became a sensation among teens. Record producers, seeing the growing popularity of the genre, signed artists who could imitate the street style of the breakers while presenting a more-wholesome image that would appeal to mainstream audiences. Breaking had gone from a street phenomenon to one that was embraced by the wider culture. It is around this time that the term break dancing was invented by the media, which often conflated the repertoire of New York breakers with such concurrent West Coast moves as “popping” and “locking.” Those routines were popularized in the early 1970s by artists on television, including Charlie Robot, who appeared on the popular TV series Soul Train.
