Scansion (// SKAN-shən, rhymes with mansion; verb: to scan), or a system of scansion, is the method or practice of determining and (usually) graphically representing the metrical pattern of a line of verse. In classical poetry, these patterns are quantitative based on the different lengths of each syllable. In English poetry, they are based on the different levels of stress placed on each syllable. In both cases, the meter often has a regular foot. Over the years, many systems have been established to mark the scansion of a poem.
Systems of scansion, and the assumptions (often tacit or even subconscious) that underlie them, are so numerous and contradictory that it is often difficult to tell whether differences in scansion indicate opposed metrical theories, conflicting understandings of a line's linguistic character, divergent practical goals, or whether they merely constitute a trivial argument over who has the "better ear" for verse. There is even a debate among scholars as to what systems were inherited from the Greek and Roman poetry.
To understand any form of scansion, it is necessary to appreciate the difference between meter and rhythm.
The rhythm of language is infinitely varied; all aspects of language contribute to it: loudness, pitch, duration, pause, syntax, repeated elements, length of phrases, frequency of polysyllabic words... As C.S. Lewis observes, "[i]f the scansion of a line meant all the phonetic facts, no two lines would scan the same way".
Meter is another matter. It is an ordering of language by means of an extremely limited subset of its characteristics. In English (and in many modern languages) the language is ordered by syllabic stress. All other aspects of language are present, indeed they are vital to the rhythm of the verse; but they are not ordered by the meter.
However, marking stress is not the same as marking meter. A perfectly regular line of iambic pentameter may have anywhere from 2 to 9 stresses, but it is still felt to exhibit 5 pulses or beats. This can most easily be understood through the principle of relative stress: an unstressed syllable between 2 even slightly weaker syllables may be perceived as a beat; and the reverse is true of a stressed syllable between 2 even slightly stronger syllables. These phenomena are called "promotion" and "demotion". Thus a syllable, regardless of its level of stress, that realizes a beat is ictic; and a syllable, regardless of its level of stress, that does not is nonictic. Ictus refers to the position within a line that is experienced as a beat, or to the syllable that fills it.
T.V.F. Brogan issues a stern warning about the temptations of overly detailed scansion:
Since meter is a system of binary oppositions in which syllables are either marked or unmarked (long or short; stressed or unstressed), a binary code is all that is necessary to transcribe it. . . . It is natural to want to enrich scansion with other kinds of analyses which capture more of the phonological and syntactic structure of the line . . . But all such efforts exceed the boundary of strict metrical analysis, moving into descriptions of linguistic rhythm, and thus serve to blur or dissolve the distinction between meter and rhythm. Strictly speaking, scansion marks which syllables are metrically prominent – i.e. ictus and nonictus – not how much. Scansions which take account of more levels of metrical degree than two, or intonation, or the timing of syllables are all guilty of overspecification.
Prosodists seldom explicitly state what they are marking in their scansions. For clarity, scansions that mark only ictus and nonictus will be called "metrical scansions", and those which mark stress or other linguistic characteristics will be called "rhythmic scansions".
Minimally, graphic scansion requires only two symbols, designating ictic and non-ictic syllables. These symbols are typically placed over the first vowel in every syllable. Some prosodists indicate only ictic (or, in rhythmic scansion, only stressed) syllables, but this is not ideal since the number, position, and character of non-ictic syllables is also metrically significant.
Additionally, many prosodists divide a line into feet—the minimal repeated units—using the pipe symbol (|). When feet are thus designated, words that span feet are divided without hyphens, and any punctuation that occurs at a foot break is typically omitted.
× / × / × / × / × / When I | consid | er how | my light | is spent
Not all prosodists agree that foot scansion is helpful.  For example, in trisyllabic measures (anapestic, amphibrachic, dactylic) it is often quite arbitrary where one divides the feet, and the salient fact seems to be the number of non-ictic syllables —in this case two— between each ictus, rather than whether the repeated pattern is imagined as ××/, ×/×, or /××. Foot analysis tends to imply that there is a special relationship among syllables within feet which does not apply across feet, but this is doubtful. Furthermore, iambic pentameter (despite its name) may be better described as a series of 10 positions than of 5 feet, especially since the sequence ××// may be interpreted as the swapping of ictic and non-ictic positions across feet, suggesting that if feet constitute any kind of boundary at all, it is a porous one indeed.
Finally, a caesura may be indicated. In the great majority of verse in English caesurae are not part of the metrical pattern, and generally it is better not to include them in English scansion. If they are to be marked: (1) if feet are being marked with a pipe (|) then caesurae will be marked with a double pipe (||) and will replace the foot marker when they occur in the same place; (2) if feet are not marked then caesurae may be marked with a single pipe. The fourteener typically does have a metrical caesura; examples of style (1) and (2) are shown below:
× / × / × / × / × / × / × / (1) The prince | ly pal | ace of | the sun || stood gor | geous to | behold × / × / × / × / × / × / × / (2) On stately pillars builded high | of yellow burnished gold
Common 2- 3- and 4-level notations
Metrical scansion explicitly requires a 2-level notation. Because of the variety of stress levels in language, 2-level notation is not adequate for a rhythmic scansion of any sensitivity. Yet, because of the confusion between rhythm and meter, the number of levels used is no sure indication of a prosodist's intent.
|Classical||Slash & breve||Slash & x||Notes|
|–||/||/||Ictus (or stressed syllable in rhythmic scansion)|
|˘||˘||x or ×||Nonictus (or unstressed syllable in rhythmic scansion)|
Classical: This notation simply retains the classical symbols for "long" and "short" syllables – the macron (or longum) and breve (or brevis) – and repurposes them for "ictic" and "nonictic" (or "stressed" and "unstressed"). Because it quite literally doesn't mean what it says, it is generally out of favor with metrists. This notation has been used by George Saintsbury and Edgar Allan Poe.
Slash & breve: This notation replaces the macron with a slash (or the graphically similar acute accent), the more common symbol for either ictus or stress. Though the classical breve is still present, its pairing with slash indicates that it has been relieved of its original "short" meaning. This notation has the advantage that its symbols can be incorporated into words as diacritics ("áccĕntĕd sýllăblĕ"). But strictly speaking it can be seen as sending the mixed message that syllables are being marked as stressed or short which would be a nonsensical scansion. This notation has been used by Paul Fussell and Miller Williams.
Slash & x: This notation is unambiguous (apart from the question of whether "/" indicates stress or ictus), easy to type, and frequently used. This is the notation preferred by the Poetry WikiProject for Wikipedia articles displaying scansion. It cannot be utilized as diacritics, and therefore always requires 2 lines (1 for the verse, and 1 for the scansion). This notation has been used by James McAuley, Timothy Steele, Robert B. Shaw, and the Princeton Encyclopedia of Poetry and Poetics; and as a secondary method by Derek Attridge.
× / × / × / × / × / When Ajax strives, some rock's vast weight to throw, × / × / × / × / × / The line too labours, and the words move slow;
This metrical scansion does not attempt to show the various rhythmic features that would occur in a competent reading. Nor does it imply that the line should be read monotonously in only 2 registers ("when Ajax STRIVES some ROCK'S vast WEIGHT to THROW"). Its simple function is to show how these lines relate to other lines of verse by marking whether syllables fill ictic or nonictic positions in the line.
Although both lines of Pope quoted above are metrically identical regular pentameters, they create that same basic metrical pattern in very different ways. To show this, one must note the rhythm, not just the meter, of the lines, and recourse must be had to additional levels of notation. In the instance below, the third symbol (\) designates stressed but demoted syllables:
× / × / \ / \ / × / When Ajax strives, some rock's vast weight to throw, × / \ / × × × / \ / The line too labours, and the words move slow;
If the meanings of all 3 symbols are defined and used strictly enough, a 3-level scansion can be both metrical and rhythmic; however, typically it will gravitate toward the rhythmic, as this scansion does. In the second line, "and" is both unstressed and ictic, but the scansion marks it only as unstressed. Although this is now a better representation of the rhythm of the line, Brogan's chickens have come home to roost: the first line's 3-level scansion may tend to obscure the basic metrical pattern, but the second line's scansion actually falsifies it. (Does the second line comprise 4 or 6 metrical prominences? The answer is, still, 5, but that could not be deduced from this rhythmic scansion.)
|\||\||•||2||Secondary stress (specific definitions vary by prosodist; for some this may simply designate any secondary stress, or it may designate demoted (stressed & nonictic) syllables, promoted (unstressed & ictic) syllables, or both)|
|x or ×||˘||˘||1||Unstressed|
Enid Hamer's notation has also been used by Harvey Gross and Susanne Woods, and it is the graphical basis for Derek Attridge's more complex notation (below).
4-level scansion is generally a sign of a more linguistically oriented prosodist at work. Otto Jespersen introduced his numeric notation in 1900 (in Danish; English translation in 1933). He occasionally added a 5th level, indicating a fully stressed syllable further emphasized by phrasal stress. In 1951 Trager & Smith posited 4 phonemic levels of stress in English. This was in a broad linguistic context, not specifically pertaining to verse; nevertheless, in the 1950s and 1960s linguistically oriented prosodists (such as John Thompson, Harold Whitehall, and Seymour Chatman) attempted to use these 4 levels of stress to formulate a fuller explanation of meter. Chomsky & Halle's work did not specifically address verse, but their notation of stress (effectively, Jespersen's turned upside-down) was also influential; Chomsky & Halle posited more than 4 levels of stress, but typically only 4 are used in scansion.
|4||/||1||///||Strongest stress (typically ictic)|
|1||˘||4||[no mark]||Least stress (typically nonictic)|
In addition to 4 levels of stress, Trager & Smith posited 4 levels of pitch, and 4 levels of juncture (basically the smoothness of transition between syllables). All 3 suprasegmentals have been used by prosodists to map out lines of verse; this comes about as close to C.S. Lewis's "all the phonetic facts" as possible, and constitutes (as Chatman makes explicit), neither the meter nor even the "phonetic facts" of the text, but a transcription of one reading of the text. Here superscript numerals indicate pitch, and "|" and "#" indicate juncture.
˘ ˘ / ˘ ˘ ^ ˘ ^ ˘ / ˘ / ²There was ³never a sound²|²beside the wood²|²but ³one# 
Jespersen was not the first to use numerals to mark stress, Alexander John Ellis used them (starting with 0 for least stress) as early as 1873. Nor were W.K. Wimsatt & Monroe Beardsley the first to use multiple slashes: none other than Thomas Jefferson used a 5-level notational system of accents ("////" for strongest stress, down to "/" for little stress, and no mark for "no" stress).
Steele and McAuley have used Jespersen's 4-level notation as a secondary method. Wimsatt, Woods, and The New Princeton Encyclopedia of Poetry and Poetics have used Chomsky & Halle's notation as a secondary method.
One of the primary virtues of 4-level scansion is that it helps clarify a surprisingly specific—and surprisingly controversial—debate. Take the rhythmically complex line:
When to the sessions of sweet silent thought
Some prosodists hear "-ions of sweet si-" as a very light iamb, followed by a very heavy iamb, yielding a 2-level metrical scansion of:
/ × × / × / × / × / When to the sess | ions of sweet si | lent thought
("Foot" markers are used here merely to emphasize the syllables in question. Recall that this metrical scansion does not imply that "of" is necessarily spoken with more emphasis than "sweet", only that these fill ictic and nonictic positions, respectively.)
However, other prosodists hold that, just as the usual 2nd position ictus has been switched to 1st position, so the usual 6th position ictus has been switched to 7th, yielding:
/ × × / × × / / × / When to the sess | ions of sweet si | lent thought
In this case, "-ions of sweet si-" is sometimes taken as a pyrrhic foot followed by a spondee, and sometimes as a single 4-syllable unit (a minor or rising ionic) that replaces 2 iambic feet. This is a case in which 2-level scansion is felt to miss something essential even by some rather strict prosodists. In fact, Groves has shown that in cases like this, where the ictus moves forward (as opposed to backward as in "When to") each of the 4 positions in question has slightly different constraints that must be fulfilled for the line to be perceived as metrical. In layman's terms, these constraints are most often realized as 4 rising positions; in Jespersen's notation:
3 2 1 4 1 2 3 4 1 4 When to the sess | ions of sweet si | lent thought
In this case, everyone is somewhat right: the 4 positions are like a light then a heavy iamb, and like a pyrrhic followed by a spondee, and like a 4-syllable "ascending foot" that functions as a unit.
The two main approaches to scansion result in a conundrum: metrical scansion necessarily ignores significant differences in stress, the very signal that meter orders; yet rhythmic scansion obscures meter and tends to be overly subjective. Jespersen provided the components of a solution to this problem by both (1) marking multiple levels of syllable stress, and (2) defining the meter of iambic pentameter as a series of 10 syllabic positions, differentiated by rising or falling levels of stress. Numeric stress levels are as described above, and "a" and "B" represent weak and strong positions in the line; alternatively (3) "a/b\a/b..." represents relatively stressed or unstressed positions, where the slash and backslash simply indicate stress levels increasing or decreasing.
(1) 2 4 1 4 3 4 3 4 1 4 When Ajax strives, some rock's vast weight to throw, (2) a B a B a B a B a B
(1) 1 4 3 4 1 2 1 4 3 4 The line too labours, and the words move slow; (3) a /b \ a / b\a / b \ a /b \ a / b
However, Jespersen did not fully integrate his notation (even to the level implied by the scansions above). It remained for the Russian linguistic-statistical school to systematize it; in their 1968 study of Russian verse, A. N. Kolmogorov and A. V. Prokhorov used a system which made both stress and ictus explicit simultaneously. This basic approach has subsequently been used to scan English verse by Marina Tarlinskaja, Derek Attridge, and Peter L. Groves, though their systems differ in detail and purpose.
In addition to making rhythm and meter distinct, all three prosodists provide explicit rules for assigning stress levels so that, as far as possible, this becomes an objective process driven by lexicon and syntax, rather than depending upon the "ear" of the scanner. Their works must be consulted for details, but a simplified version of Groves's rules can provide a first approximation:
- Primary stress: the primarily stressed syllable in content words (nouns, verbs, adjectives, and adverbs).
- Secondary stress: the secondarily stressed syllables of polysyllabic content words; the most strongly stressed syllable in polysyllabic function words (auxiliary verbs, conjunctions, pronouns, prepositions); subsidiary stress in compound words.
- Unstressed: unstressed syllables of polysyllabic words; monosyllabic function words.
For comparative purposes, the following table is a somewhat simplified rendition of these scansion systems. Attridge (1982) and Groves scan ictus/nonictus on a separate line.
|Tarlinskaja 1987||Attridge||Attridge 1995||Groves|
Tarlinskaja, Attridge, and Groves each exhibit distinct conceptions regarding the dispositions of ictus and nonictus.
Tarlinskaja uses scansion as a basis for statistical analysis of verse. She has used several versions of the scansion levels shown above, some more and some less fine-grained, and some reduced to numerical values; but all relate to this basic 3 × 2 structure. In the metrical component of her scansion, she (like Jespersen) marks the ictic and nonictic positions of the meter, not of the line. This allows her to compare patterns across hundreds or thousands of verse lines statistically, using a consistent matrix of positions. Thus in the line
∈ – ∪ ⊥ ∪ – ∈ ⊥ ∪ ⊥ When to the sessions of sweet silent thought
where both Attridge and Groves (and most prosodists, for that matter) would say that the first syllable is ictic, Tarlinskaja rigidly keeps the ictus in the second position, which is its "average" position across iambic pentameter.
Attridge's scansion is intended to be broadly applicable, using a few symbols and rules to describe a wide range of English lines consistently, without a priori reducing them to one metrical system. Like Tarlinskaja, he considers that ictus and nonictus (in his notation B for "beat" and o for "offbeat") always alternate, but matches beats to prominent syllables by allowing offbeat positions to be filled by 0, 1, or 2 syllables (represented by ô, o, and ǒ respectively). The top line represents his "single-line" scansion from 1995, and the lower lines uses his original two-line system of 1982 (these are theoretically identical, only graphically different).
/ x x / x x / [x]/ x / When to the sessions of sweet silent thought +s -s -s +s -s -s +s +s -s +s B ǒ B ǒ B ô B o B
Peter L. Groves
To date, Groves has put forward his system only as an explanation of iambic pentameter (or "the English heroic line" as he prefers to call it), though elements may be applicable to other accentual-syllabic meters.
He begins his rhythmic scansion with a three-level label for all syllables, but goes much further by elaborating rules describing how contiguous syllables impinge upon each other. The result is a map of the lexical and syntactic character of a line's syllables, which results in stress; rather than a representation of stress levels themselves.
|Independent||A||B||O||A syllable of any of the three main categories that is neither impinged upon by a neighbor, nor specially emphasized in context (e.g. by contrastive accent).|
|Dominated/Subordinated||a||b||o||Prevented from carrying a beat by a stronger neighbor (except "a", which can be allowed in loose versification).|
|Inhibited/Demoted||Ā||Ō||Ā is "demoted": it cannot dominate or subordinate a neighbor; Ō is "inhibited": it is discouraged, but not wholly prevented, from carrying a beat.|
|Accented||A||B||O||Specially emphasized in context (e.g. contrastive accent); these syllables may impinge more strongly on their neighbors than regular A, B, O.|
Ictus (S for "strong") and nonictus (w for "weak") have constraints on which syllable statuses can fill them. These rules for matching syllable status and metrical position are called "mapping rules", and strict (e.g. Alexander Pope) versus loose (e.g. William Shakespeare) styles of iambic pentameter can be defined by applying different mapping rules.
Further, while his metrical scansion begins as a familiar wSwSwSwSwS, he allows "w" and "S" to trade places under certain conditions, and when they do their mapping rules are altered, requiring additional symbols. In the first (rhythmic) line of scansion, syllables that impinge on their neighbors are connected by hyphens; in the second (metrical) line, positions that have switched places and therefore altered their mapping rules are connected by hyphens.

Other methods of scansion
In 1880, Sidney Lanier published The Science of English Verse, in which he developed a novel theory exploring the connections between musical notation and meter in poetry. Although some figures such as T.S. Osmond and Harriet Monroe praised it, others did not view it kindly. For example, Vladimir Nabokov in his Notes on Prosody says: "In my casual perusals, I have of course slammed shut without further ado any such works on English prosody in which I glimpsed a crop of musical notes." (pages 3–4) Harvey Gross' criticism also described the theory as lacking in good sense, saying "it scatters sand in the eyes and pours wax in the ears."
One account cited that musical scansion was an experimental technique during the nineteenth century but was obscured by the then existing conventional scansion. An interpretation of the notion of musical scansion states three theories: 1) beats occur at regular intervals of time; 2) syllables of a verse can be grouped in measures or "bars"; and 3) beats form a hierarchy of strength.

|^||Stressed||Syllable carries the stress|
|–||Heavy||Is genuinely long, slows down the reading. For example: broad, bright, down.|
|˘||Light||All syllables with short vowels, even those that would be long 'by position' in Classical terms. That is, if the consonants around a short vowel do not genuinely retard the syllable then it will be counted 'light'. Light also includes all classically short syllables. For example, the second syllables of 'brighter' and 'brightest' are both light, despite the consonants in the latter. (Bridges also mentions "short" as a subset of "light" syllables, but with "seldom any cause to distinguish" between them; he is not found to have scanned any syllables specifically as short.)|
George R. Stewart
|l||light stressed syllable|
|O||heavy unstressed syllable|
|p||pause in place of unstressed syllable|
|P||pause in place of stressed syllable|
|L||normally light stress raised to greater prominence in dipodic verse|
Stewart's notation influenced John Crowe Ransom and John Thompson, though they did not use his full roster of symbols.

- Edward Bysshe, whose Art of English Poetry was quite popular throughout the 18th century, was probably the earliest influential prosodist to deny that feet play a part in English verse. Though George R. Stewart used foot terminology to describe verse, his scansion ignored feet, concentrating instead on syntactic groupings. Most modern dissent, however, can be seen in terms of Otto Jespersen's resolute denial of the "fallacy of the foot" (1979, p 109); he described verse lines instead as a series of "weak" and "strong" positions, and both generative metrists and "rhythmi-metrical" scanners have generally followed in his anti-footsteps. Halle & Keyser (1972, p 222) dismiss the foot, their signal concept the "Stress Maximum" explicitly transcending (or transgressing) its boundaries. Paul Kiparsky however (a later generativist) reinstates the concept of the foot ("Generative Metrics" in Preminger & Brogan 1993, pp 452–53). Derek Attridge (1982, p 17) says, "[a]t best, then, the division of lines into feet adds nothing, at worst it hinders accurate analysis of the metrical variations which all readers perceive." Alone among the "rhythmi-metrical" scanners Peter L. Groves reintroduces "notional" feet at a very general level (they figure in his verse theory but not in his actual scansions), but he distances his notion from that of traditional metrics (1998, p 107). T.V.F. Brogan ("Foot" in Preminger & Brogan 1993, p 419) threads the needle, saying that the foot is "more than a mere analytic tool, a device of scansion: it is a principle of structure" yet that it is "not necessarily an element in poetic composition ... and it is almost certainly not an element of performance"; and finally that "[i]n scansion, it can be used to describe and analyze verse whose regularities support it, and not verse which does not."
