Elements

Prosody

Prosody is the study of the meter, rhythm, and intonation of a poem. Rhythm and meter, although closely related, should be distinguished. Meter is the definitive pattern established for a verse (such as iambic pentameter), while rhythm is the actual sound that results from a line of poetry. Thus, the meter of a line may be described as being "iambic", but a full description of the rhythm would require noting where the language causes one to pause or accelerate and how the meter interacts with other elements of the language. Prosody also may be used more specifically to refer to the scanning of poetic lines to show meter.

Rhythm

The methods for creating poetic rhythm vary across languages and between poetic traditions. Languages are often described as having timing set primarily by accents, syllables, or moras, depending on how rhythm is established, though a language can be influenced by multiple approaches. Japanese is a mora-timed language. Syllable-timed languages include Latin, Catalan, French, Leonese, Galician and Spanish. English, Russian and, generally, German are stress-timed languages. Varying intonation also affects how rhythm is perceived. Languages also can rely on either pitch, such as in Vedic or ancient Greek, or tone. Tonal languages include Chinese, Vietnamese, Lithuanian, and most subsaharan languages.

Metrical rhythm generally involves precise arrangements of stresses or syllables into repeated patterns called feet within a line. In Modern English verse the pattern of stresses primarily differentiate feet, so rhythm based on meter in Modern English is most often founded on the pattern of stressed and unstressed syllables (alone or elided). In the classical languages, on the other hand, while the metrical units are similar, vowel length rather than stresses define the meter. Old English poetry used a metrical pattern involving varied numbers of syllables but a fixed number of strong stresses in each line.

The chief device of ancient Hebrew Biblical poetry, including many of the psalms, was parallelism, a rhetorical structure in which successive lines reflected each other in grammatical structure, sound structure, notional content, or all three. Parallelism lent itself to antiphonal or call-and-response performance, which could also be reinforced by intonation. Thus, Biblical poetry relies much less on metrical feet to create rhythm, but instead creates rhythm based on much larger sound units of lines, phrases and sentences. Some classical poetry forms, such as Venpa of the Tamil language, had rigid grammars (to the point that they could be expressed as a context- free grammar) which ensured a rhythm. In Chinese poetry, tones as well as stresses create rhythm. Classical Chinese poetics identifies four tones: the level tone, rising tone, departing tone, and entering tone. Note that other classifications may have as many as eight tones for Chinese and six for Vietnamese.

The formal patterns of meter used in Modern English verse to create rhythm no longer dominate contemporary English poetry. In the case of free verse, rhythm is often organized based on looser units of cadence rather than a regular meter. Robinson Jeffers, Marianne Moore, and William Carlos Williams are three notable poets who reject the idea that regular accentual meter is critical to English poetry. Jeffers experimented with sprung rhythm as an alternative to accentual rhythm.

Meter

In the Western poetic tradition, meters are customarily grouped according to a characteristic metrical foot and the number of feet per line. Thus, "iambic pentameter" is a meter comprising five feet per line, in which the predominant kind of foot is the "iamb". This metric system originated in ancient Greek poetry, and was used by poets such as Pindar and Sappho, and by the great tragedians of Athens. Similarly, "dactylic hexameter", comprises six feet per line, of which the dominant kind of foot is the "dactyl". Dactylic hexameter was the traditional meter of Greek epic poetry, the earliest extant examples of which are the works of Homer and Hesiod. More recently, iambic pentameter and dactylic hexameter have been used by William Shakespeare and Henry Wadsworth Longfellow, respectively.

Meter is often scanned based on the arrangement of "poetic feet" into lines. In English, each foot usually includes one syllable with a stress and one or two without a stress. In other languages, it may be a combination of the number of syllables and the length of the vowel that determines how the foot is parsed, where one syllable with a long vowel may be treated as the equivalent of two syllables with short vowels. For example, in ancient Greek poetry, meter is based solely on syllable duration rather than stress. In some languages, such as English, stressed syllables are typically pronounced with greater volume, greater length, and higher pitch, and are the basis for poetic meter. In ancient Greek, these attributes were independent of each other; long vowels and syllables including a vowel plus more than one consonant actually had longer duration, approximately double that of a short vowel, while pitch and stress (dictated by the accent) were not associated with duration and played no role in the meter. Thus, a dactylic hexameter line could be envisioned as a musical phrase with six measures, each of which contained either a half note followed by two quarter notes (i.e. a long syllable followed by two short syllables), or two half notes (i.e. two long syllables); thus, the substitution of two short syllables for one long syllable resulted in a measure of the same length. Such substitution in a stress language, such as English, would not result in the same rhythmic regularity. In Anglo-Saxon meter, the unit on which lines are built is a half-line containing two stresses rather than a foot. Scanning meter can often show the basic or fundamental pattern underlying a verse, but does not show the varying degrees of stress, as well as the differing pitches and lengths of syllables.

As an example of how a line of meter is defined, in English-language iambic pentameter, each line has five metrical feet, and each foot is an iamb, or an unstressed syllable followed by a stressed syllable. When a particular line is scanned, there may be variations upon the basic pattern of the meter; for example, the first foot of English iambic pentameters is quite often inverted, meaning that the stress falls on the first syllable.The generally accepted names for some of the most commonly used kinds of feet include:

iamb – one unstressed syllable followed by a stressed syllable

trochee – one stressed syllable followed by an unstressed syllable

dactyl – one stressed syllable followed by two unstressed syllables

anapest – two unstressed syllables followed by one stressed syllable

spondee – two stressed syllables together

pyrrhic – two unstressed syllables together (rare, usually used to end dactylic hexameter)

The number of metrical feet in a line are described in Greek terminology as follows:

dimeter – two feet

trimeter – three feet

tetrameter – four feet

pentameter – five feet

hexameter – six feet

heptameter – seven feet

octameter – eight feet

There are a wide range of names for other types of feet, right up to a choriamb of four syllable metric foot with a stressed syllable followed by two unstressed syllables and closing with a stressed syllable. The choriamb is derived from some ancient Greek and Latin poetry. Languages which utilize vowel length or intonation rather than or in addition to syllabic accents in determining meter, such as Ottoman Turkish or Vedic, often have concepts similar to the iamb and dactyl to describe common combinations of long and short sounds.

Each of these types of feet has a certain "feel," whether alone or in combination with other feet. The iamb, for example, is the most natural form of rhythm in the English language, and generally produces a subtle but stable verse. The dactyl, on the other hand, almost gallops along. And, in the manner of The Night Before Christmas or Dr. Seuss, the anapest is said to produce a light-hearted, comic feel.

There is debate over how useful a multiplicity of different "feet" is in describing meter. For example, Robert Pinsky has argued that while dactyls are important in classical verse, English dactylic verse uses dactyls very irregularly and can be better described based on patterns of iambs and anapests, feet which he considers natural to the language. Actual rhythm is significantly more complex than the basic scanned meter described above, and many scholars have sought to develop systems that would scan such complexity. Vladimir Nabokov noted that overlaid on top of the regular pattern of stressed and unstressed syllables in a line of verse was a separate pattern of accents resulting from the natural pitch of the spoken words, and suggested that the term "scud" be used to distinguish an unaccented stress from an accented stress.

Metrical patterns

Different traditions and genres of poetry tend to use different meters, ranging from the Shakespearian iambic pentameter and the Homeric dactylic hexameter to the Anapestic tetrameter used in many nursery rhymes. However, a number of variations to the established meter are common, both to provide emphasis or attention to a given foot or line and to avoid boring repetition. For example, the stress in a foot may be inverted, a caesura (or pause) may be added (sometimes in place of a foot or stress), or the final foot in a line may be given a feminine ending to soften it or be replaced by a spondee to emphasize it and create a hard stop. Some patterns (such as iambic pentameter) tend to be fairly regular, while other patterns, such as dactylic hexameter, tend to be highly irregular. Regularity can vary between language. In addition, different patterns often develop distinctively in different languages, so that, for example, iambic tetrameter in Russian will generally reflect a regularity in the use of accents to reinforce the meter, which does not occur, or occurs to a much lesser extent, in English.

Some common metrical patterns, with notable examples of poets and poems who use them, include:

Iambic pentameter (John Milton, Paradise Lost

Dactylic hexameter (Homer, Iliad;[45] Virgil, Aeneid; Ovid, Metamorphoses)

Iambic tetrameter (Andrew Marvell, "To His Coy Mistress"; Aleksandr Pushkin, Eugene Onegin)

Trochaic octameter (Edgar Allan Poe, "The Raven")

Anapestic tetrameter (Lewis Carroll, "The Hunting of the Snark"; Lord Byron, Don Juan)

Alexandrine (Jean Racine, Phèdre)

Rhyme, alliteration, assonance

The Old English epic poem Beowulf is written in alliterative verse and paragraphs, not in lines or stanzas.

Rhyme, alliteration, assonance and consonance are ways of creating repetitive patterns of sound. They may be used as an independent structural element in a poem, to reinforce rhythmic patterns, or as an ornamental element.

Rhyme consists of identical ("hard-rhyme") or similar ("soft-rhyme") sounds placed at the ends of lines or at predictable locations within lines ("internal rhyme"). Languages vary in the richness of their rhyming structures; Italian, for example, has a rich rhyming structure permitting maintenance of a limited set of rhymes throughout a lengthy poem. The richness results from word endings that follow regular forms. English, with its irregular word endings adopted from other languages, is less rich in rhyme. The degree of richness of a language's rhyming structures plays a substantial role in determining what poetic forms are commonly used in that language.

Alliteration and assonance played a key role in structuring early Germanic, Norse and Old English forms of poetry. The alliterative patterns of early Germanic poetry interweave meter and alliteration as a key part of their structure, so that the metrical pattern determines when the listener expects instances of alliteration to occur. This can be compared to an ornamental use of alliteration in most Modern European poetry, where alliterative patterns are not formal or carried through full stanzas. Alliteration is particularly useful in languages with less rich rhyming structures. Assonance, where the use of similar vowel sounds within a word rather than similar sounds at the beginning or end of a word, was widely used in skaldic poetry, but goes back to the Homeric epic. Because verbs carry much of the pitch in the English language, assonance can loosely evoke the tonal elements of Chinese poetry and so is useful in translating Chinese poetry. Consonance occurs where a consonant sound is repeated throughout a sentence without putting the sound only at the front of a word. Consonance provokes a more subtle effect than alliteration and so is less useful as a structural element.

In 'A Linguistic Guide to English Poetry' (Longmans, 1969) Geoffrey Leech identified six different types of sound patterns or rhyme forms. These are defined as six possible ways in which either one or two of the structural parts of the related words can vary. The unvarying parts are in upper case/bold. C symbolises a consonant cluster, not a single consonant, V a vowel.

Type    Pattern            ; Example 1       Example 2

Alliteration     C v c   great/grow      send/sit

Assonance      c V c   great/fail         send/bell

Consonance    c v C   great/meat       send/hand

Reverse Rhyme          C V c  great/grazed    send/sell

Pararhyme       C v C  great/groat      send/sound

Rhyme          &nb sp; c V C  great/bait         send/bend

In many languages, including modern European languages and Arabic, poets use rhyme in set patterns as a structural element for specific poetic forms, such as ballads, sonnets and rhyming couplets. However, the use of structural rhyme is not universal even within the European tradition. Much modern poetry avoids traditional rhyme schemes. Classical Greek and Latin poetry did not use rhyme. Rhyme entered European poetry in the High Middle Ages, in part under the influence of the Arabic language in Al Andalus (modern Spain). Arabic language poets used rhyme extensively from the first development of literary Arabic in the sixth century, as in their long, rhyming qasidas. Some rhyming schemes have become associated with a specific language, culture or period, while other rhyming schemes have achieved use across languages, cultures or time periods. Some forms of poetry carry a consistent and well- defined rhyming scheme, such as the chant royal or the rubaiyat, while other poetic forms have variable rhyme schemes.

Most rhyme schemes are described using letters that correspond to sets of rhymes, so if the first, second and fourth lines of a quatrain rhyme with each other and the third line does not rhyme, the quatrain is said to have an "a-a-b-a" rhyme scheme. This rhyme scheme is the one used, for example, in the rubaiyat form. Similarly, an "a-b-b-a" quatrain (what is known as "enclosed rhyme") is used in such forms as the Petrarchan sonnet.Some types of more complicated rhyming schemes have developed names of their own, separate from the "a-b-c" convention, such as the ottava rima and terza rima. The types and use of differing rhyming schemes is discussed further in the main article.

Ottava rima

Ottava rima is a rhyming scheme using a stanza of eight lines with an alternating a-b rhyming scheme for the first six lines followed by a closing couplet. First used by Boccaccio, it was developed for heroic epics but has also been used for mock-heroic poetry.

Terza rima

Dante's Divine Comedy is written in terza rima, where each stanza has three lines, with the first and third rhyming, and the second line rhyming with the first and third lines of the next stanza (thus, a-b-a / b-c-b / c-d-c, et cetera.) in a chain rhyme. The terza rima provides a flowing, progressive sense to the poem, and used skilfully it can evoke a sense of motion, both forward and backward. Terza rima is appropriately used in lengthy poems in languages with rich rhyming structures (such as Italian, with its many common word endings).

Form

Poetic form is more flexible in modernist and post- modernist poetry, and continues to be less structured than in previous literary eras. Many modern poets eschew recognisable structures or forms, and write in free verse. But poetry remains distinguished from prose by its form; some regard for basic formal structures of poetry will be found in even the best free verse, however much such structures may appear to have been ignored. Similarly, in the best poetry written in classic styles there will be departures from strict form for emphasis or effect.

Among major structural elements used in poetry are the line, the stanza or verse paragraph, and larger combinations of stanzas or lines such as cantos. Also sometimes used are broader visual presentations of words and calligraphy. These basic units of poetic form are often combined into larger structures, called poetic forms or poetic modes (see following section), as in the sonnet or haiku.

Lines and stanzas

Poetry is often separated into lines on a page. These lines may be based on the number of metrical feet, or may emphasize a rhyming pattern at the ends of lines. Lines may serve other functions, particularly where the poem is not written in a formal metrical pattern. Lines can separate, compare or contrast thoughts expressed in different units, or can highlight a change in tone. See the article on line breaks for information about the division between lines.

Lines of poems are often organized into stanzas, which are denominated by the number of lines included. Thus a collection of two lines is a couplet (or distich), three lines a triplet (or tercet), four lines a quatrain, five lines a quintain (or cinquain), six lines a sestet, and eight lines an octet. These lines may or may not relate to each other by rhyme or rhythm. For example, a couplet may be two lines with identical meters which rhyme or two lines held together by a common meter alone. Stanzas often have related couplets or triplets within them.

Other poems may be organized into verse paragraphs, in which regular rhymes with established rhythms are not used, but the poetic tone is instead established by a collection of rhythms, alliterations, and rhymes established in paragraph form. Many medieval poems were written in verse paragraphs, even where regular rhymes and rhythms were used.

In many forms of poetry, stanzas are interlocking, so that the rhyming scheme or other structural elements of one stanza determine those of succeeding stanzas. Examples of such interlocking stanzas include, for example, the ghazal and the villanelle, where a refrain (or, in the case of the villanelle, refrains) is established in the first stanza which then repeats in subsequent stanzas. Related to the use of interlocking stanzas is their use to separate thematic parts of a poem. For example, the strophe, antistrophe and epode of the ode form are often separated into one or more stanzas. In such cases, or where structures are meant to be highly formal, a stanza will usually form a complete thought, consisting of full sentences and cohesive thoughts.

In some cases, particularly lengthier formal poetry such as some forms of epic poetry, stanzas themselves are constructed according to strict rules and then combined. In skaldic poetry, the dróttkvætt stanza had eight lines, each having three "lifts" produced with alliteration or assonance. In addition to two or three alliterations, the odd numbered lines had partial rhyme of consonants with dissimilar vowels, not necessarily at the beginning of the word; the even lines contained internal rhyme in set syllables (not necessarily at the end of the word). Each half-line had exactly six syllables, and each line ended in a trochee. The arrangement of dróttkvætts followed far less rigid rules than the construction of the individual dróttkvætts.

Visual presentation

Arabic poetry

Visual poetry

Even before the advent of printing, the visual appearance of poetry often added meaning or depth. Acrostic poems conveyed meanings in the initial letters of lines or in letters at other specific places in a poem. In Arabic, Hebrew and Chinese poetry, the visual presentation of finely calligraphed poems has played an important part in the overall effect of many poems.

With the advent of printing, poets gained greater control over the mass-produced visual presentations of their work. Visual elements have become an important part of the poet's toolbox, and many poets have sought to use visual presentation for a wide range of purposes. Some Modernist poets have made the placement of individual lines or groups of lines on the page an integral part of the poem's composition. At times, this complements the poem's rhythm through visual caesuras of various lengths, or creates juxtapositions so as to accentuate meaning, ambiguity or irony, or simply to create an aesthetically pleasing form. In its most extreme form, this can lead to concrete poetry or asemic writing.

Poetic diction

Poetic diction treats of the manner in which language is used, and refers not only to the sound but also to the underlying meaning and its interaction with sound and form. Many languages and poetic forms have very specific poetic dictions, to the point where distinct grammars and dialects are used specifically for poetry. Registers in poetry can range from strict employment of ordinary speech patterns, as favoured in much late 20th century prosody, through to highly ornate and aureate uses of language by such as the medieval and renaissance makars.

Poetic diction can include rhetorical devices such as simile and metaphor, as well as tones of voice, such as irony. Aristotle wrote in the Poetics that "the greatest thing by far is to be a master of metaphor." Since the rise of Modernism, some poets have opted for a poetic diction that deemphasizes rhetorical devices, attempting instead the direct presentation of things and experiences and the exploration of tone. On the other hand, Surrealists have pushed rhetorical devices to their limits, making frequent use of catachresis.

Allegorical stories are central to the poetic diction of many cultures, and were prominent in the West during classical times, the late Middle Ages and the Renaissance. Rather than being fully allegorical, however, a poem may contain symbols or allusions that deepen the meaning or effect of its words without constructing a full allegory.

Another strong element of poetic diction can be the use of vivid imagery for effect. The juxtaposition of unexpected or impossible images is, for example, a particularly strong element in surrealist poetry and haiku. Vivid images are often, as well, endowed with symbolism.

Many poetic dictions use repetitive phrases for effect, either a short phrase (such as Homer's "rosy-fingered dawn" or "the wine-dark sea") or a longer refrain. Such repetition can add a somber tone to a poem, as in many odes, or can be laced with irony as the context of the words changes. For example, in Antony's famous eulogy of Caesar in Shakespeare's Julius Caesar, Antony's repetition of the words, "For Brutus is an honorable man," moves from a sincere tone to one that exudes irony.

Forms

Poetic form

Specific poetic forms have been developed by many cultures. In more developed, closed or "received" poetic forms, the rhyming scheme, meter and other elements of a poem are based on sets of rules, ranging from the relatively loose rules that govern the construction of an elegy to the highly formalized structure of the ghazal or villanelle. Described below are some common forms of poetry widely used across a number of languages. Additional forms of poetry may be found in the discussions of poetry of particular cultures or periods and in the glossary.

Sonnet

Among the most common forms of poetry through the ages is the sonnet, which by the thirteenth century was a poem of fourteen lines following a set rhyme scheme and logical structure. A sonnet's first four lines typically introduce the topic. A sonnet usually follows an a-b-a-b rhyme pattern. The sonnet's conventions have changed over its history, and so there are several different sonnet forms. Traditionally, in sonnets English poets use iambic pentameter, the Spenserian and Shakespearean sonnets being especially notable. In the Romance languages, the hendecasyllable and Alexandrine are the most widely used meters, though the Petrarchan sonnet has been used in Italy since the 14th century. Sonnets are particularly associated with love poetry, and often use a poetic diction heavily based on vivid imagery, but the twists and turns associated with the move from octave to sestet and to final couplet make them a useful and dynamic form for many subjects. Shakespeare's sonnets are among the most famous in English poetry, with 20 being included in the Oxford Book of English Verse. The relative prominence of a poet or set of works is often measured by reference to inclusion in the Oxford Book of English Verse or the Norton Anthology of Poetry.

 Jintishi

The jintishi (近體詩) is a Chinese poetic form based on a series of set tonal patterns using the four tones of Middle Chinese in each couplet: the level, rising, departing and entering tones. The basic form of the jintishi has eight lines in four couplets, with parallelism between the lines in the second and third couplets. The couplets with parallel lines contain contrasting content but an identical grammatical relationship between words. Jintishi often have a rich poetic diction, full of allusion, and can have a wide range of subject, including history and politics. One of the masters of the form was Du Fu, who wrote during the Tang Dynasty (8th century). There are several variations on the basic form of the jintishi.

Sestina

The sestina has six stanzas, each comprising six unrhymed lines, in which the words at the end of the first stanza’s lines reappear in a rolling pattern in the other stanzas. The poem then ends with a three- line stanza in which the words again appear, two on each line.

Villanelle

The Villanelle is a nineteen-line poem made up of five triplets with a closing quatrain; the poem is characterized by having two refrains, initially used in the first and third lines of the first stanza, and then alternately used at the close of each subsequent stanza until the final quatrain, which is concluded by the two refrains. The remaining lines of the poem have an a-b alternating rhyme. The villanelle has been used regularly in the English language since the late nineteenth century by such poets as Dylan Thomas, W. H. Auden, and Elizabeth Bishop. It is a form that has gained increased use at a time when the use of received forms of poetry has generally been declining.[citation needed]

Pantoum

The pantoum is a rare form of poetry similar to a villanelle. It is composed of a series of quatrains; the second and fourth lines of each stanza are repeated as the first and third lines of the next.

Rondeau 

The rondeau was originally a French form, written on two rhymes with fifteen lines, using the first part of the first line as a refrain.

Roundel

 The roundel form, said to have been devised by Swinburne, consists of nine lines plus a refrain after the third line and after the last line, the refrain being identical with the beginning of the first line.

Tanka

Tanka is a form of unrhymed Japanese poetry, with five sections totalling 31 onji (phonological units identical to morae), structured in a 5-7-5 7-7 pattern. There is generally a shift in tone and subject matter between the upper 5-7-5 phrase and the lower 7-7 phrase. Tanka were written as early as the Nara period by such poets as Kakinomoto no Hitomaro, at a time when Japan was emerging from a period where much of its poetry followed Chinese form. Tanka was originally the shorter form of Japanese formal poetry, and was used more heavily to explore personal rather than public themes. It thus had a more informal poetic diction. By the 13th century, tanka had become the dominant form of Japanese poetry, and it is still widely written today. The 31-mora rule is generally ignored by poets writing literary tanka in languages other than Japanese.

Haiku

Haiku is a popular form of unrhymed Japanese poetry, which evolved in the 17th century from the hokku, or opening verse of a renku. Generally written in a single vertical line, the haiku contains three sections totalling 17 onji (see above, at Tanka), structured in a 5-7-5 pattern. Traditionally, haiku contain (1) a kireji, or cutting word, usually placed at the end of one of the poem's three sections; and (2) a kigo, or season- word.

Ruba'i

Ruba'i is a four-line verse (quatrain) practiced by Arabian, Persian, Urdu, Azerbaijani (Azeri) poets.

Sijo

Sijo is a short musical lyric practiced by Korean poets. It is usually written as three lines, each averaging 14-16 syllables, for a total of 44-46 syllables. There is a pause in the middle of each line and so, in English, a sijo is sometimes printed in six lines rather than three. An example is given below:

You ask how many friends I have? Water and stone, bamboo and pine.

The moon rising over the eastern hill is a joyful comrade.

Besides these five companions, what other pleasure should I ask?

Ode

Odes were first developed by poets writing in ancient Greek, such as Pindar, and Latin, such as Horace. Forms of odes appear in many of the cultures that were influenced by the Greeks and Latins. The ode generally has three parts: a strophe, an antistrophe, and an epode. The antistrophes of the ode possess similar metrical structures and, depending on the tradition, similar rhyme structures. In contrast, the epode is written with a different scheme and structure. Odes have a formal poetic diction, and generally deal with a serious subject. The strophe and antistrophe look at the subject from different, often conflicting, perspectives, with the epode moving to a higher level to either view or resolve the underlying issues. Odes are often intended to be recited or sung by two choruses (or individuals), with the first reciting the strophe, the second the antistrophe, and both together the epode. Over time, differing forms for odes have developed with considerable variations in form and structure, but generally showing the original influence of the Pindaric or Horatian ode. One non-Western form which resembles the ode is the qasida in Persian poetry.

 Ghazal

The ghazal (Arabic: ghazal, Persian: ghazel, Turkish/Azerbaijani: gazel, Urdu: gazal, Bengali/Sylheti: gozol) is a form of poetry common in Arabic, Persian, Turkish, Azerbaijani, Urdu and Bengali poetry. In classic form, the ghazal has from five to fifteen rhyming couplets that share a refrain at the end of the second line. This refrain may be of one or several syllables, and is preceded by a rhyme. Each line has an identical meter. Each couplet forms a complete thought and stands alone, and the overall ghazal often reflects on a theme of unattainable love or divinity. The last couplet generally includes the signature of the author.

As with other forms with a long history in many languages, many variations have been developed, including forms with a quasi- musical poetic diction in Urdu. Ghazals have a classical affinity with Sufism, and a number of major Sufi religious works are written in ghazal form. The relatively steady meter and the use of the refrain produce an incantatory effect, which complements Sufi mystical themes well. Among the masters of the form is Rumi, a 13th-century Persian poet who lived in Konya, in present-day Turkey.

Acrostic

An acrostic (from the late Greek akróstichon, from ákros, "top", and stíchos, "verse") is a poem or other form of writing in an alphabetic script, in which the first letter, syllable or word of each line, paragraph or other recurring feature in the text spells out another message. A form of constrained writing, an acrostic can be used as a mnemonic device to aid memory retrieval.

A famous acrostic comes from the acclamation, "Jesus Christ, God's son, savior," which in Greek is: "Ἰησοῦς Χριστός, Θεοῦ ͑Υιός, Σωτήρ", Iēsous Christos, Theou Huios, Sōtēr. The initial letters of each word spell ichthys, the Greek word for fish; hence the frequent use of the fish as a symbol for Jesus Christ.

The Jewish devotional prayer Ashrei has lines beginning with each of the letters of the Hebrew alphabet in turn, implying that Jews ought to praise God with each letter of the alphabet. Likewise, the prayer Ashamnu, recited on Yom Kippur (the Day of Atonement), lists sins beginning with each letter of the alphabet, emphasizing the breadth and universality of wrongdoing.

Canzone

Literally "song" in Italian, a canzone (plural: canzoni) (cognate with English to chant) is an Italian or Provençal song or ballad. It is also used to describe a type of lyric which resembles a madrigal. Sometimes a composition which is simple and songlike is designated as a canzone, especially if it is by a non-Italian; a good example is the aria "Voi che sapete" from Mozart's Marriage of Figaro.

Cinquain

While "quintain" is the general term applied to poetic forms using a 5-line pattern, there are specific forms within that category that are defined by specific rules and guidelines. The term "CINQUAIN" (pronounced SING-cane, the plural is "cinquains") as applied by modern poets most correctly refers to a form invented by the American poet Adelaide Crapsey. The first examples of these were published in 1915 in The Complete Poems, roughly a year after her death. Her cinquain form was inspired by Japanese haiku and Tanka (a form of Waka).

Other forms of poetry include:

Carmina figurata

Concrete poetry: Word arrangement, typeface, color or other visual effects are used to complement or dramatize the meaning of the words used.

Fixed verse

Folk song

Free verse: based on the irregular rhythmic cadence or the recurrence, with variations, of phrases, images, and syntactical patterns rather than the conventional use of meter.

Limerick

Minnesang

Murabba

Pastourelle

Poetry slam: This is a modern style of spoken word poetry, frequently associated with a distinctive style of delivery.
