rhyme scheme

A rhyme scheme is the pattern of rhymes at the end of each line of a poem or song. It is usually referred to by using letters to indicate which lines rhyme; lines designated with the same letter all rhyme with each other.

An example of the ABAB rhyming scheme, from "To Anthea, who may Command him Anything", by Robert Herrick:

Function in writing

These rhyme patterns have various effects, and can be used to:

* Control flow: If every line has the same rhyme (AAAA), the stanza will read as having a very quick flow, whereas a rhyme scheme like ABCABC can be felt to unfold more slowly.
* Structure a poem's message and thought patterns: For example, a simple couplet with a rhyme scheme of AABB lends itself to simpler direct ideas, because the resolution comes in the very next line. Essentially these couplets can be thought of as self-contained statements. This idea of rhyme schemes reflecting thought processes is often discussed particularly regarding sonnets.
* Determine whether a stanza is balanced or unbalanced.
* Help to reinforce the feeling being expressed: If the writer wants to express stubbornness, they may use tight structured rhyme schemes, whereas if one was writing about feeling lost, then perhaps the stanza would only have one rhyme (XXAXXXA).

A basic distinction is between rhyme schemes that apply to a single stanza, and those that continue their pattern throughout an entire poem (see chain rhyme). There are also more elaborate related forms, like the sestina – which requires repetition of exact words in a complex pattern. Rhyming is not a mandatory feature of poetry; a four-line stanza with non-rhyming lines could be described as using the scheme ABCD.

Notation and examples

Notation used below:
* ABAB – Four-line stanza, first and third lines rhyme at the end, second and fourth lines rhyme at the end.
* AB AB – Two two-line stanzas, with the first lines rhyming at the end and the second lines rhyming at the end.
* AB,AB – Single two-line stanza, with the two lines having both a single internal rhyme and a conventional rhyme at the end.
* aBaB – Two different possible meanings for a four-line stanza:
** First and third lines rhyme at the end, second and fourth lines are repeated verbatim.
** First and third lines have a feminine rhyme and the second and fourth lines have a masculine rhyme.
* – Two stanzas, where the first lines of both stanzas are exactly the same, and the last lines of both stanzas are the same. The second lines of the two stanzas are different, but rhyme at the end with the first and last lines. (In other words, all the "A" and "a" lines rhyme with each other, but not with the "b" lines.)
* XAXA – Four lines, two unrhymed (X) and two with the same end rhyme (A)

Other notation examples:
* Indicating the number of stressed syllables in certain lines: AA⁴B²CC⁴ or AA₄B₂CC₄
* Some publications use lowercase or have punctuation to separate lines or stanzas, e.g. or . (These variations are not used elsewhere in this article, for clarity.)

In hip-hop music

Hip-hop music and rapping's rhyme schemes include traditional schemes such as couplets, as well as forms specific to the genre, which are broken down extensively in the books '' How to Rap'' and '' Book of Rhymes''. Rhyme schemes used in hip-hop music include
* CoupletsEdwards, Paul, 2009, '' How to Rap: The Art & Science of the Hip-Hop MC'', Chicago Review Press, p. 99.
*Single-liners
*Multi-liners
*Combinations of schemes
*Whole verse

Couplets are the most common type of rhyme scheme in old school rap and are still regularly used, though complex rhyme schemes have progressively become more frequent. Rather than relying on end rhymes, rap rhyme schemes can have rhymes placed anywhere in the bars of music to create a structure. There can also be numerous rhythmic elements which all work together in the same schemeEdwards, Paul, 2009, '' How to Rap: The Art & Science of the Hip-Hop MC'', Chicago Review Press, p. 104. – this is called internal rhyme in traditional poetry, though rap rhymes schemes can be anywhere in the bar, they could all be internal, so the term is not always used. Rap verses can also employ 'extra rhymes', which do not structure the verse like the main rhyme schemes, but which add to the overall sound of the verse.Edwards, Paul, 2009, '' How to Rap: The Art & Science of the Hip-Hop MC'', Chicago Review Press, p. 103.

Number of rhyme schemes for a poem with ''n'' lines

The number of different possible rhyme schemes for an ''n''-line poem is given by the Bell numbers,. Reprinted with an addendum as "The Tinkly Temple Bells", Chapter 2 of ''Fractal Music, Hypercards, and more ... Mathematical Recreations from Scientific American'', W. H. Freeman, 1992, pp. 24–38.
which for ''n'' = 1, 2, 3, ... are
:1, 2, 5, 15, 52, 203, 877, 4140, 21147, 115975, .. .

Examples: We find one rhyme scheme for a one-line poem (A), two different rhyme schemes for a two-line poem (AA, AB), and five for a three-line poem: AAA, AAB, ABA, ABB, and ABC.

These counts, however, include rhyme schemes in which rhyme is not employed at all (ABCD). There are many fewer rhyme schemes when all lines must rhyme with at least one other line; a count of these is given by the numbers,
:0, 1, 1, 4, 11, 41, 162, 715, 3425, 17722, ... .
For example, for a three-line poem, there is only one rhyming scheme in which every line rhymes with at least one other (AAA), while for a four-line poem, there are four such schemes (AABB, ABAB, ABBA, and AAAA).
