Why did DJ Kool Herc call his two-turntable method the merry-go-round?

DJ Kool Herc coined the term "merry-go-round" to describe his innovative two-turntable technique because it allowed him to loop and extend the percussive instrumental breaks of songs indefinitely.1

By using two copies of the same record on two turntables and a mixer, he could transition seamlessly from one break to the next, creating a continuous flow of music for dancers. He observed that these breaks—the sections of a song featuring heavy percussion—were the moments that most energized the crowd, and by looping them, he provided a sustained rhythmic foundation for dancers to perform their moves. This technique not only kept the dance floor active for longer periods but also directly led to the naming of the dancers who performed during these extended breaks as "break-boys" and "break-girls," or "B-boys" and "B-girls".12
