===Rap notation===
The standard form of rap notation is the "flow diagram", where rappers line up their lyrics underneath "beat numbers".{{sfnp|Edwards|2009|p=67}} Hip-hop scholars also make use of the same flow diagrams that rappers use: the books ''How to Rap'' and ''How to Rap 2'' extensively use the diagrams to explain rap's triplets, flams, rests, rhyme schemes, runs of rhyme, and breaking rhyme patterns, among other techniques.{{sfnp|Edwards|2013|p=53}} Similar systems are used by musicologists Adam Krims in his book ''Rap Music and the Poetics of Identity''{{sfnp|Krims|2001|pp=59–60}} and Kyle Adams in his work on rap's flow.{{sfnp|Adams|2009}} As rap usually revolves around a strong 4/4 beat,{{sfnp|Edwards|2009|p=69}} with certain syllables aligned to the beat, all the notational systems have a similar structure: they all have four beat numbers at the top of the diagram, so that syllables can be written in-line with the beat.{{sfnp|Edwards|2009|p=69}}
