 He says rap lyrics are made up of, "lines with four stressed beats, separated by other syllables that may vary in number and may include other stressed syllables.The strong beat of the accompaniment coincides with the stressed beats of the verse, and the rapper organizes the rhythms of the intervening syllables to provide variety and surprise".The same technique is also noted in the book "How to Rap", where diagrams are used to show how the lyrics line up with the beat – "stressing a syllable on each of the four beats gives the lyrics the same underlying rhythmic pulse as the music and keeps them in rhythm ... other syllables in the song may still be stressed, but the ones that fall in time with the four beats of a bar are the only ones that need to be emphasized in order to keep the lyrics in time with the music".
