Overview

A rhyme scheme is the ordered pattern of end-rhymes in a stanza or complete poem. Poets mark which lines rhyme with one another using letters: the first rhyme is A, the next new rhyme B, and so on. The resulting sequence — for example ABAB, AABB, or ABBA — identifies how sound repeats across lines. Rhyme schemes serve as a structural tool: they create expectation, reinforce rhythm, highlight refrains, and can shape meaning by grouping lines that respond to each other sonically.

Notation and basic patterns

Notation is simple and widely understood: identical letters denote matching end-rhymes, different letters indicate different rhymes. Some common short patterns include AA (a couplet), AAA (a triplet), AABB (paired couplets), ABAB (alternate rhyme), and ABBA (enclosed or envelope rhyme). With longer stanzas or fixed forms, schemes become more elaborate: lines may follow ABABABCC or ABABBCC, and tercets or quatrains inside a larger poem can combine to form the overall pattern.

Named schemes and fixed forms

Certain stanza types and classical forms carry conventional schemes. For example, the seven-line pattern ABABBCC is known as rhyme royal, while ABABABCC is the structure of ottava rima. The extended Spenserian stanza combines a long sequence ending in a couplet and is often given as ABABBBCBCC. Sonnets display varied schemes depending on tradition: Italian or Petrarchan sonnets commonly use ABBA ABBA followed by a sestet such as CDE CDE or CDC DCD, French and English adaptations alter these patterns, and the English or Shakespearean sonnet is typically ABAB CDCD EFEF GG. For general reading on sonnets see sonnets.

Examples, internal rhyme and sound devices

Rhyme schemes refer to end sounds, but poems also use internal rhyme and other sonic devices. Internal rhyme occurs within a line or between nearby words, and is often paired with alliteration, consonance or assonance to enrich texture. A famous example of internal rhyme and alliteration appears in Samuel Taylor Coleridge's lines: "The fair breeze blew, the white foam flew, / The furrow followed free", where the repetition of the -ew sound and initial consonants intensifies musicality; see Coleridge and the related concept of alliteration. Short extracts like Robert Herrick's quatrain demonstrate a clear ABAB layout, while Robert Browning used less common alignments in poems such as "Meeting at Night"; you can read analyses of Browning's use of rhyme and sound for narrative effect.

Variety, language differences and poetical preference

Languages influence how rhyme schemes function. In syllable-timed languages or those with abundant vowel endings (for example Italian or Spanish), many rhymes share vowel sounds and produce dense rhyming patterns without heavy consonant repetition. In English, with its greater variety of word endings, poets often choose schemes that suit the stress and syntax of the line. Individual poets may favor particular patterns: for instance, Robert Burns frequently used an AAABAB pattern in some of his songs and lyrics; see discussions of Burns and dialect song forms. Certain schemes, like simple AABBCC, are ubiquitous and unspecific, while others — for example ABCCBA or interlocking forms — are rarer and can create surprising structural effects.

Uses, analysis and composing with schemes

Rhyme schemes affect pacing, emphasis and reader expectation. Paired rhymes (AABB) can feel conclusive, alternate rhymes (ABAB) maintain forward motion, and enclosed forms (ABBA) can create a mirrored or reflective sensation. Analysts of poetry use rhyme schemes to identify form, trace influences, and compare translations. Poets selecting a scheme consider not only sonic repetition but also stanza length, meter, and thematic development: a repeating couplet may underscore a refrain, whereas a final GG couplet in a sonnet often delivers a volta or summation. Understanding rhyme schemes helps readers appreciate how sound and structure work together to produce the distinctive effects of individual poems and genres.
