Using the two turntable set-up of the disco DJs, Campbell's style led to the use of two copies of the same record to elongate the break. This breakbeat DJing, using hard funk, rock, and records with Latin percussion, formed the basis of hip hop music. Campbell's announcements and exhortations to dancers helped lead to the syncopated, rhymed spoken accompaniment now known as rapping. He called his dancers "break-boys" and "break-girls", or simply b-boys and b-girls. Campbell's DJ style was quickly taken up by figures such as Afrika Bambaataa and Grandmaster Flash. Unlike them, he never made the move into commercially recorded hip hop in its earliest years.
