"Rappers speak of flow explicitly in lyrics, referring to an ability to move easily and powerfully through complex lyrics as well as of the flow in the music. The flow and motion of the initial bass or drum line in rap music is abruptly ruptured by scratching (a process that highlights as it breaks the flow of the base rhythm), or the rhythmic flow is interrupted by other music passages. Rappers stutter and alternatively race through passages always moving within the beat or in response to it, often using the music as a partner in rhyme. Rappers layer meaning by using the same word to signify a variety of actions and objects; they call out to the DJ to 'lay down a beat,' which is expected to be interrupted, ruptured. DJs layer sounds literally one on top of the other, creating a dialogue between sampled sounds and words . . . one can argue that [these concepts] create and sustain rhythmic motion, continutiy, and circularity via flow; accumulate, reinforce, and embellish this continuity through layering; and manage threats to these narratives by building in ruptures that highlight the continuity as it momentarily challenges it" (BN 39).
