Example An iambic foot is an unstressed syllable followed by a stressed syllable. The rhythm can be written as: da DUM A standard line of iambic pentameter is five iambic feet in a row: da DUM da DUM da DUM da DUM da DUM Straightforward examples of this rhythm can be heard in the opening line of
William Shakespeare's
Sonnet 12: and in
John Keats's ode
To Autumn: It is possible to notate this with a "/" marking
ictic syllables (experienced as beats) and a "×" marking nonictic syllables (experienced as offbeats). In this notation a standard line of iambic pentameter would look like this: × / × / × / × / × / The
scansion of the examples above can be notated as follows: × / × / × / × / × / When I do count the clock that tells the time × / × / × / × / × / To swell the gourd, and plump the hazel shells
The iamb in classical and English verse The term "iamb" originally applied to the
quantitative meter of classical poetry. The classical terms were adapted to describe the equivalent meters in English
accentual-syllabic verse. Different languages express rhythm in different ways. In
Ancient Greek and
Latin, the rhythm was created through the alternation of
short and long syllables. In
English, the rhythm is created through the use of
stress, alternating between unstressed and stressed syllables. An English unstressed syllable is equivalent to a classical short syllable, while an English stressed syllable is equivalent to a classical long syllable. When a pair of syllables is arranged as a short followed by a long, or an unstressed followed by a stressed, pattern, that foot is said to be "iambic". The English word "
trapeze" is an example of an iambic pair of syllables, since the word is made up of two syllables ("tra-peze") and is pronounced with the stress on the second syllable ("tra-", rather than "-peze"). A line of iambic pentameter is made up of five such pairs of short/long, or unstressed/stressed, syllables.
Rhythmic variation Although strictly speaking, iambic pentameter refers to five iambs in a row (as above), in practice, poets vary their iambic pentameter a great deal, while maintaining the iamb as the most common foot. However, there are some conventions to these variations. Iambic pentameter must always contain only five feet, and the second foot is almost always an iamb. The first foot, in contrast, often changes by the use of
inversion, which reverses the order of the syllables in the foot. The following line from
Shakespeare's
Richard III begins with an inversion: / × × / × / × / × / Now is the winter of our discontent Besides inversion, whereby a beat is pulled back, a beat can also be pushed
forward to create an indivisible 4-syllable unit: x x / /. In the following example, the 4th beat has been pushed forward: x / x / x / x x / / A mote it is to trouble the mind's eye Another common departure from standard iambic pentameter is the addition of a final unstressed syllable, which creates a
weak or
feminine ending. One of Shakespeare's most famous lines of iambic pentameter has a weak ending: × / × / × / / × × / (×) To be or not to be, | that is the question This line also has an inversion of the fourth foot, following the
caesura (marked with "|"). In general a caesura acts in many ways like a line-end: inversions are common after it, and the extra unstressed syllable of the feminine ending may appear before it. Shakespeare and
John Milton (in his work before
Paradise Lost) at times employed feminine endings before a caesura. Here is the first quatrain of a
sonnet by
John Donne, which demonstrates how he uses a number of metrical variations strategically. This scansion adds numbers to indicate how Donne uses a variety of stress levels to realize his beats and offbeats (1 = lightest stress, 4 = heaviest stress): 4 1 1 4 3 4 1 4 1 2 / × × / × / × / × / Batter my heart three-personed God, for you 1 3 2 4 3 4 1 4 1 4 × / × / × / × / × / As yet but knock, breathe, shine and seek to mend. 1 2 1 4 1 4 2 4 1(1) 4 × / × / × / × / ×(×) / That I may rise and stand o'erthrow me and bend 1 4 1 4 3 4 1 4 1 4 × / × / × / × / × / Your force to break, blow, burn and make me new. Donne uses an inversion (DUM da instead of da DUM) in the first foot of the first line to stress the key verb, "batter", and then sets up a clear iambic pattern with the rest of the line (da DUM da DUM da DUM da DUM). In the second and fourth lines he uses strongly-stressed offbeats (which can be interpreted as
spondees) in the third foot to slow down the rhythm as he lists monosyllabic verbs. The parallel rhythm and grammar of these lines highlights the comparison Donne sets up between what God does to him "as yet" ("knock, breathe, shine and seek to mend"), and what he asks God to do ("break, blow, burn and make me new"). Donne also uses
enjambment between lines three and four to speed up the flow as he builds to his desire to be made new. To further the speed-up effect of the enjambment, Donne puts an extra syllable in the final foot of the line (this can be read as an
anapest (dada DUM) or as an
elision).
Percy Bysshe Shelley also used skilful variation of the metre in his "
Ode to the West Wind": × / × / | × / × / × /(×) O wild West Wind, thou breath of Autumn's being, / × × / × / × × / / Thou, from whose unseen presence the leaves dead × / × / / × × / × / (×) Are driven, like ghosts from an enchanter fleeing, As the examples show, iambic pentameter need not consist entirely of iambs, nor need it have ten syllables. Most poets who have a great facility for iambic pentameter frequently vary the rhythm of their poetry as Donne and Shakespeare do in the examples, both to create a more interesting overall rhythm and to highlight important thematic elements. In fact, the skilful
variation of iambic pentameter, rather than the consistent use of it, may well be what distinguishes the rhythmic artistry of Donne, Shakespeare, Milton, and the 20th century
sonneteer
Edna St. Vincent Millay. Several scholars have argued that iambic pentameter has been so important in the history of English poetry by contrasting it with the one other important meter (
tetrameter), variously called "four-beat," "strong-stress," "native meter," or "four-by-four meter." Four-beat, with four beats to a line, is the meter of nursery rhymes, children's jump-rope and counting-out rhymes, folk songs and ballads, marching cadence calls, and a good deal of art poetry. It has been described by Attridge as based on doubling: two beats to each half line, two half lines to a line, two pairs of lines to a stanza. The metrical stresses alternate between light and heavy. It is a heavily regular beat that produces something like a repeated tune in the performing voice, and is, indeed, close to song. Because of its odd number of metrical beats, iambic pentameter, as Attridge says, does not impose itself on the natural rhythm of spoken language. Thus iambic pentameter frees intonation from the repetitiveness of four-beat and allows instead the varied intonations of significant speech to be heard. Pace can be varied in iambic pentameter, as it cannot in four-beat, as
Alexander Pope demonstrated in his "
An Essay on Criticism": In the first couplet, in phrases like "Ajax strives", "rock's vast weight", "words move slow", the long vowels and accumulation of consonants make the syllables long and slow the reader down; whereas in the second couplet, in the word "Camilla" all the syllables are short, even the stressed one. The last line is in fact an
alexandrine—an iambic hexameter, which occurs occasionally in some iambic pentameter texts as a variant line, most commonly the final line of a passage or stanza, and has a tendency, as in this example, to break in the middle, producing a symmetry, with its even number of syllables split into two halves, that contrasts with the
asymmetry of the 5-beat pentameter line. Pope exemplifies "swiftness" partly through his use of contraction—two extra implied syllables squeezed into the metrical template between the first two ictuses: / ×(×) (×)× / × / × / × / × / Flies o'er th'unbending corn, and skims along the main. Moreover, iambic pentameter, instead of the steady alternation of lighter and heavier beats of four-beat, permits principal accents, that is, accents on the most significant words, to occur at various points in a line as long as they are on the even-numbered syllables, or on the first syllable, in the case of an initial trochaic inversion. It is not the case, as is often alleged, that iambic pentameter is "natural" to English; rather it is that iambic pentameter allows the varied intonations and pace natural to significant speech to be heard along with the regular meter. == Theories of iambic pentameter ==
