Prosody and metre in Indian languages

In short

Prosody (Sanskrit *chhandas-shastra*, Hindi *chhand-shastra*, Urdu *ilm-ul-aruz*, Tamil *yappilakkanam*) is the science of how a line of verse is organised - by syllable count, by syllabic weight, by moraic (matra) count, or by foot patterns - and of the rules that let you name and scan a metre. It matters because every classical Indian text before the modern period is in metre: you cannot date, edit, emend or translate a verse without scanning it, and a missing syllable is often the first clue to a corrupt manuscript reading. It is examined in BA and MA papers on *Chhand-Alankar*, *Bhasha Vigyan*, Sanskrit *Vyakarana-Chhandas*, Urdu *Aruz-o-Qafia* and Tamil *Yappu-Ani*, and appears in UGC-NET/JRF, state SET/TET, PGT Hindi/Sanskrit recruitment (KVS, NVS, DSSSB, Navodaya) and in interviews for editorial, lexicography, textbook, subtitling, lyric-writing and TTS/speech-technology roles.

Explained

1. The two foundations: syllable and mora

• Akshara / varna (syllable): a vowel with its preceding consonants. Sanskrit prosody counts *syllables*, not letters: *kṛṣ-ṇaḥ* is two syllables.
• **Laghu (short, ⏑, marked । or U): a syllable with a short vowel - a, i, u, ṛ, ḷ - and nothing heavy after it. One matra** (mora).
• **Guru (long, —, marked S or ऽ): two matras. A syllable is guru if it has (a) a long vowel - ā, ī, ū, e, ai, o, au; or (b) a short vowel followed by anusvara (ṁ) or visarga (ḥ); or (c) a short vowel followed by a consonant cluster** (samyuktakshara), because the first consonant closes the syllable.
• Last syllable of a line (pada-anta) may be counted guru even if short - *pādānte tu laghu api guruḥ* - at the scanner's option; this is why the odd quarters of a shloka seem to end "long".
• A conjunct in the *next* word still closes the previous syllable: in *tat tvam*, *tat* is guru.
• Plutam (⏓, three matras): a protracted vowel, marked 3; relevant to Vedic recitation and to vocative calls, rarely to metrical counting.

2. Classification of metres

Indian prosody splits metres on *what is being counted*:

1. Varnavritta / aksharavritta (syllabic-quantitative): a fixed number of syllables per quarter AND a fixed laghu-guru sequence. Example: Mandakranta, 17 syllables, one pattern only. This is the dominant Sanskrit type.
   • Samavritta: all four quarters identical (Indravajra, Vasantatilaka, Shardulavikridita).
   • Ardhasamavritta: quarters 1 and 3 alike, 2 and 4 alike (Viyogini, Pushpitagra, Aupacchandasika).
   • Vishamavritta: all four quarters different (Udgata).
2. Matravritta / jati (moraic): only the *total matras* per quarter is fixed; laghu and guru may be substituted (one guru = two laghu) subject to local rules. Example: Arya (Sanskrit/Prakrit), Doha, Chaupai, Rola, Harigitika in Hindi.
3. Gana-chhand / ganavritta: built from repeated feet. Urdu *bahr* and Tamil *yappu* are of this kind, as are Hindi folk metres like Lavani.
4. Mukta / free verse (*mukt chhand*, *chhand-mukt*): no fixed count; introduced by Nirala (*Juhi ki Kali*, 1916), and the standard medium of Bengali *gadyachhanda*, Malayalam and Tamil *puthukkavitha*.
5. Vedic chhandas: named purely by syllable count per quarter, with a loose cadence rather than a fixed pattern - Gayatri 8×3 = 24, Ushnik 28, Anushtubh 32, Brihati 36, Pankti 40, Trishtubh 44, Jagati 48. The seven are listed in the *Rigveda* itself and in Pingala.

3. The gana system (Sanskrit) and the key varnavrittas

• Varnavrittas are described using eight trisyllabic ganas, memorised by the sutra "ya-mā-tā-rā-ja-bhā-na-sa-la-gam" (also recited as *ya mā tā rā ja bhā na sa*): read any three consecutive syllables of the sutra to get that gana's pattern.

• Single syllables outside a gana are la (laghu) and ga/gam (guru).
• Yati (caesura): a compulsory word-break inside long lines, stated as "yati at 4 and 10" etc. Gati: the flow/tempo. A line correct in ganas but wrong in yati is still faulty.
• Standard metres to know with pattern, syllables and yati:

4. The Anushtubh / Shloka rule (the single most examined item)

• 32 syllables: four quarters (*pada*) of 8; or two lines of 16.
• Fixed points only: in every quarter, syllable 5 is laghu and syllable 6 is guru; syllables 1-4 are free except that 2-3 should not both be laghu (⏑⏑ at 2-3 is avoided).
• Syllable 7: guru in odd quarters (pathya), laghu in even quarters. Syllable 8 is free (*anceps*).
• So the even-quarter cadence is the signature: ⏑ — ⏑ ⏓ (positions 5-8). The variant forms where an odd quarter deviates are the *vipula* types (bha-vipula, ra-vipula, na-vipula, ma-vipula), named after the gana appearing at syllables 2-4.
• Example - *Gita* 2.47: *karmaṇyevādhikāraste* (8) / *mā phaleṣu kadācana* (8) ... scan the second quarter: mā(—) pha(⏑) le(—) ṣu(⏑) ka(⏑) dā(—) ca(⏑) na(⏑) - position 5 laghu, 6 guru, 7 laghu. Correct even-quarter Anushtubh.

5. Hindi chhand-shastra

• Matrik (moraic) metres, counted in matras per *charan*:
  • Doha: 24 matras per line in two halves of 13 + 11; the 11-matra half ends in a guru-laghu (SI) cadence; rhyme on the two lines. Kabir, Rahim, Bihari, Tulsi.
  • Soratha: the Doha reversed - 11 + 13; rhyme falls at the half-line.
  • Chaupai: 16 matras per charan, four charans, rhymed in pairs; a charan must not end in jagan (⏑—⏑) or tagan (— —⏑). *Ramcharitmanas* is mainly Chaupai with Doha/Soratha.
  • Rola: 24 matras, 11 + 13. Kundaliya: a Doha followed by four charans of Rola, six lines in all, the last word of the Doha repeating as the opening of the Rola and the composition closing with the word it began with. Harigitika: 28 matras, 16 + 12. Barvai: 19 matras, 12 + 7. Chhappay: six lines - four Rola + two Ullala.
  • Savaiya (22-26 *varnas* - a varnik, not matrik, chhand) and Kavitt/Ghanakshari (31 syllables per line) are the Riti-period showpieces.
• Varnik metres in Hindi retain the Sanskrit names and patterns: Indravajra, Vasantatilaka, Mandakranta, Drutavilambit, Malini.
• Alha, Lavani, Birha, Rasiya are folk/gana metres tied to performance tempo rather than page count.
• Tuk (rhyme): *tukant* (rhymed) versus *atukant* (unrhymed); anuprasa is alliteration and belongs to figures of speech, not to prosody proper - a distinction examiners test.

6. Urdu aruz (ilm-ul-aruz)

• Borrowed from Arabic-Persian; the unit is a rukn (foot, plural *arkan*), built from the eight standard feet - *fa'ūlun, fā'ilun, mafā'īlun, fā'ilātun, mustaf'ilun, maf'ūlātu, mufā'alatun, mutafā'ilun* - expressed through the dummy root f-'-l.
• Bahr: a metre, i.e. a sanctioned sequence of arkan. The classical count is 19 bahrs - Hazaj, Ramal, Rajaz, Mutaqarib, Mutadarik, Kamil, Khafif, Mujtas, Mudari', Muqtadib, Munsarih, Sari', Jadid, Qarib, Mushakil, Tawil, Madid, Basit, Wafir - of which Tawil, Madid, Basit and Wafir are not used in Urdu; Hazaj, Ramal, Rajaz, Mutaqarib, Mutadarik, Khafif, Mujtas and Mudari' are the common ones.
• Taqti' (scansion): writing a line as *sabab* (2-letter), *watad* (3-letter) and *fasila* units by haruf-e-illat rules - letters that are written but not pronounced (*alif-e-wasl*, silent *h*, *izafat*) are dropped, and a long vowel may be shortened; this licence is imala/taskin.
• A couplet is a sher (two *misra*: *misra-e-ula* and *misra-e-sani*); the radif is the repeated word ending each rhyming line, the qafia the rhyming syllable before it, the matla the opening sher of a ghazal with both misras rhymed, the maqta the closing sher carrying the poet's takhallus.
• A line that does not scan is kharij-az-bahr (out of metre) - the standard adverse verdict in an Urdu *islah* session.
• Azad nazm (free verse) and nazm-e-mu'arra (blank verse, metre without rhyme) are the modern departures; Nazm Tabatabai's and Josh's practice are cited.

7. Tamil yappu and the other southern/eastern systems

• Tamil (Tolkappiyam, Yapparungalam, Yapparungalakkarikai): the units ascend - ezhuthu (letter) → asai (metrical syllable) → cheer (foot) → thalai (linkage) → adi (line) → thodai (rhyme/alliteration) → pa (metre).
  • Asai is of two kinds: ner (one long or one short unit) and nirai (two shorts followed by the rest).
  • Cheer combinations are named *thema, pulima, kuvilam, karuvilam* (two-asai feet) and so on; thalai governs how one cheer may follow another.
  • The four classical pa: venba (the *Thirukkural* is *kural venba*, two lines of 4 + 3 cheer), asiriyappa, vanjippa, kalippa; marutpa is the mixed fifth.
• Malayalam (*vritham*): besides the Sanskrit varnavrittas, the native *bhasha vrittas* (Keka, Kakali, Manjari, Natonnata, Annanada, Sarpini, Drutakakali) counted in matras with a thalam (beat) sense; *Vrittamanjari* by A. R. Rajaraja Varma is the standard manual. Pattu/Manipravalam verse follows *dravidavritta* with *etuka* (second-syllable rhyme) and *mona* (alliteration).
• Telugu and Kannada: vritta (Sanskrit metres - Utpalamala, Champakamala, Sardula), gana-based desi metres like Kanda/Kanda padya and the Telugu Teta-giti, Ata-veladi, Sisamu, using indigenous ganas (surya, indra, chandra ganas); Kannada's Vachana (prose-poetry of the Sharanas) and Shatpadi (six-line, Raghavanka/Kumaravyasa), Tripadi, Ragale. Rhyme devices: prasa (second-letter rhyme) and adiprasa.
• Bengali: three systems - aksharvritta (*tanpradhan*, syllable-counting, the medium of *payar*: 14 syllables, 8 + 6), matravritta (*kalabritta*, Tagore's favoured measure), svarvritta (*dalbritta*, stress-and-syllable, the nursery-rhyme beat). Payar and Mahapayar (14 and 16) dominate Bengali narrative verse; *amitrakshar chhanda* (blank verse) was introduced by Michael Madhusudan Dutt in *Tilottama Sambhab Kavya* (1860) and *Meghnadbadh Kavya*.
• Marathi: Ovi and Abhanga (four-line, 6+6+6+4 matras) in Bhakti verse; Shloka, Arya, Dindi, Saki, Padakulak in classical Marathi; Moropant's Aryas and Keshavsut's sonnets mark the transition.
• Punjabi/Gurmukhi: metre names in the Guru Granth Sahib - *Chaupai, Savaiya, Pauri, Sloka*, set within raga headings.

8. Texts, authorities and modern tools

• Pingala's *Chhandahsutra* (c. 3rd-2nd century BCE) is the foundational Sanskrit treatise; it is also the earliest known text to use a binary place-value notation for laghu-guru combinations, Meru-prastara (the "Pascal's triangle" of prastara) and the matrameru sequence - which is the Fibonacci sequence, anticipated by Pingala, Virahanka (c. 6th-8th c.), Gopala and Hemachandra (c. 1150).
• Pratyayas (the six combinatorial procedures of prosody): prastara (listing all patterns), nashta (find the pattern given the serial number), uddishta (find the number given the pattern), ekadvi-adi-laghu-kriya (count patterns with a given number of laghus), sankhya (total count), adhvayoga (space needed to write them all).
• Other authorities: Kedarabhatta's *Vrittaratnakara* (the most-taught handbook, each metre defined in its own metre), Halayudha's *Mritasanjivani* (commentary on Pingala), Jayadeva's *Chhandahshastra*, Hemachandra's *Chhandonushasana*, Virahanka's *Vrittajatisamuchchaya* (Prakrit), Kshemendra, and for Hindi Keshavdas's *Chhandamala* and Bhikharidas's *Chhand-Prakash*.
• Modern practice: metre-recognition software (Sanskrit metre identifiers, *chandojnanam*-type tools) scans Devanagari or IAST input and names the vritta; digital-humanities projects use it for authorship and interpolation studies, and TTS/speech-synthesis work uses laghu-guru weight for Indian-language duration modelling.
• Advantages of metre: aids memorisation and oral transmission, fixes the text against corruption, carries emotional register (Mandakranta for longing, Shardulavikridita for grandeur, Anushtubh for narration), and allows editors to detect lacunae.
• Limitations: rigid patterns force unnatural word order and compounding; matravritta substitution makes scansion ambiguous; the system cannot describe stress-based or free verse, which is why 20th-century poets abandoned it.

Key points

• Chhandas - the science of metre; one of the six Vedangas, called the "feet of the Veda" (*padau chhando*).
• Laghu - one matra: short vowel, not followed by anusvara, visarga or a consonant cluster.
• Guru - two matras: long vowel, or short vowel + anusvara/visarga/conjunct; line-final syllable optionally guru.
• Varnavritta - fixed syllable count *and* fixed laghu-guru order; matravritta/jati - fixed matra total only.
• Samavritta / ardhasamavritta / vishamavritta - four quarters identical / alternately identical / all different.
• Eight ganas - ma — — —, ya ⏑ — —, ra — ⏑ —, sa ⏑ ⏑ —, ta — — ⏑, ja ⏑ — ⏑, bha — ⏑ ⏑, na ⏑ ⏑ ⏑; mnemonic *yamātārājabhānasalagam*.
• Anushtubh - 32 syllables, 8 per pada; position 5 laghu, 6 guru, 7 guru in odd padas and laghu in even padas.
• Yati - compulsory caesura; gati - tempo. Both are part of metrical correctness, not ornament.
• Doha 13+11 matras · Soratha 11+13 · Chaupai 16 · Rola 11+13 (24) · Harigitika 16+12 (28) · Barvai 12+7 (19).
• Bahr - Urdu metre made of arkan (feet) built on the root f-'-l; taqti' is scansion; a bad line is *kharij-az-bahr*.
• Radif, qafia, matla, maqta, takhallus - the rhyme-architecture of the ghazal, distinct from its bahr.
• Tamil ladder - ezhuthu → asai (ner/nirai) → cheer → thalai → adi → pa; *Thirukkural* is kural venba.
• Bengali trio - aksharvritta, matravritta, svarvritta; payar is 14 syllables (8+6); amitrakshar = blank verse (Madhusudan Dutt).
• Pingala - *Chhandahsutra*, binary notation, Meru-prastara, matrameru (Fibonacci before Fibonacci).
• Pratyayas - prastara, nashta, uddishta, ekadvi-adi-laghu-kriya, sankhya, adhvayoga.
• Mukt chhand - free verse; Nirala in Hindi (*Juhi ki Kali*, 1916), *puthukkavitha* in Tamil, *gadyachhanda* in Bengali.
• Scansion use - a short or extra syllable flags a corrupt reading; metre is the editor's first diagnostic.

Formulas and examples

Example 1 - scan a quarter and count matras. Line: *dharmakṣetre kurukṣetre* (Gita 1.1, first pada).

• dhar = short *a* + closing *r* of a cluster → guru (2)
• ma = short, but followed by the cluster *kṣ* → guru (2)
• kṣe = long *e* → guru (2)
• tre = long *e* → guru (2)
• ku = short, open → laghu (1)
• ru = short, followed by cluster *kṣ* → guru (2)
• kṣe = guru (2)
• tre = guru (2)

Pattern: — — — — ⏑ — — —. Syllables = 8. Matras = 2+2+2+2+1+2+2+2 = 15. Check the Anushtubh rule for an odd pada: position 5 = ⏑ laghu ✔, position 6 = — guru ✔, position 7 = — guru ✔ (odd pada requires guru). A regular pathya Anushtubh.

Example 2 - identify a varnavritta from its ganas. Pattern: — — — / — ⏑ ⏑ / ⏑ ⏑ ⏑ / — — ⏑ / — — ⏑ / — — (17 syllables).

• Group in threes: — — — = ma, — ⏑ ⏑ = bha, ⏑ ⏑ ⏑ = na, — — ⏑ = ta, — — ⏑ = ta, then — — = ga ga.
• Scheme ma-bha-na-ta-ta-ga-ga, 17 syllables, yati at 4, 6, 7 → Mandakranta (the metre of Kalidasa's *Meghaduta*).
• Matras = ma 6 + bha 4 + na 3 + ta 5 + ta 5 + ga 2 + ga 2 = 27 matras in 17 syllables.

Example 3 - verify a Doha. Rahim: *rahiman dhaga prem ka, mat chatakāvo tōṛi* — count the first half.

• ra(1) hi(1) man(2, nasal close) dha(1) ga(1) pre(2) m... *prem* = pre + m closing → 2 ; ka(1) → running total 1+1+2+1+1+2+1 = 9. The traditional scansion of this half reaches 13 matras when *rahiman* is read *ra-hi-ma-na* and the elided final vowel of *dhāgā* is counted long; the printed text is conventionally scanned 13.
• Second half must be 11 matras and must end guru-laghu (SI): *tōṛi* = tō (2) + ṛi (1) = S I ✔.
• Rule check: 13 + 11 = 24 matras per line, two lines, end-rhyme on the two lines → Doha. If the second half ended laghu-guru, the couplet would be faulty.

Example 4 - Pingala's combinatorics. How many laghu-guru patterns exist for a quarter of 8 syllables, and how many of them have exactly 3 gurus?

• Total = 2⁸ = 256 patterns (*sankhya*).
• With exactly 3 gurus = ⁸C₃ = (8×7×6)/(3×2×1) = 56 (*Meru-prastara*, row 8).
• Of these 256, the Anushtubh rule fixes positions 5, 6 and 7 and leaves 1-4 and 8 free, so the permitted shapes of one odd pada = 2⁵ = 32, less the ones with laghu at both 2 and 3 (2³ = 8) = 24 acceptable patterns.

Example 5 - matrameru (Virahanka-Fibonacci). How many distinct laghu-guru sequences add up to 6 matras?

• S₁ = 1 (⏑), S₂ = 2 (⏑⏑, —), then Sₙ = Sₙ₋₁ + Sₙ₋₂.
• S₃ = 2+1 = 3; S₄ = 3+2 = 5; S₅ = 5+3 = 8; S₆ = 8+5 = 13.
• So a 6-matra foot can be filled 13 ways - the count a poet implicitly draws on when substituting one guru for two laghus in a matravritta.

Where it is used

• Textbook and school publishing (NCERT, SCERTs, Rajkamal, Vani, Sahitya Akademi, Maktaba Jamia): editing chhand-alankar chapters, marking matras in verse anthologies, correcting metrical errors in poems set for Classes 9-12.
• Critical editing and manuscript work (Bhandarkar Oriental Research Institute, Oriental Research Institute Mysore, IGNCA, Rashtriya Sanskrit Sansthan, Asiatic Society): metre is the primary test for interpolations, lacunae and variant readings.
• Broadcast, film and music (All India Radio/Prasar Bharati, Doordarshan, film lyric-writing, devotional and ghazal composition): a lyricist is expected to keep a line *bahr*-correct and to fit matras to a *taal*; Urdu *islah* and mushaira practice is still metre-based.
• Language technology: Indian-language TTS and ASR duration models, Sanskrit metre-identification and OCR post-correction tools, poetry-generation and digital-humanities authorship studies at IIT Bombay, IIT Kanpur, IIIT Hyderabad, C-DAC and the TDIL programme.
• Teaching and recruitment: PGT/TGT Hindi, Sanskrit, Urdu, Tamil and Bengali posts (KVS, NVS, DSSSB, state PSCs, Navodaya) and UGC-NET/JRF - chhand questions are near-certain in these papers.
• Translation, subtitling and dubbing: rendering metrical verse into another language while keeping line-length and beat - Sahitya Akademi and National Translation Mission projects, and lip-sync dubbing where syllable count must match.

Interview questions

• Q: What makes a syllable guru? A: A long vowel, or a short vowel followed by anusvara, visarga or a consonant cluster; the last syllable of a line may also be counted guru by licence.
• Q: Difference between varnavritta and matravritta? A: Varnavritta fixes both the number of syllables and the exact laghu-guru order; matravritta fixes only the total matras, so one guru may be replaced by two laghus.
• Q: State the Anushtubh rule. A: Four padas of eight syllables; in each pada syllable 5 is laghu and 6 is guru, syllable 7 is guru in odd padas and laghu in even padas, and syllable 8 is free.
• Q: What is *yamatarajabhanasalagam*? A: The mnemonic sutra of the eight trisyllabic ganas - any three consecutive syllables of it give that gana's laghu-guru pattern.
• Q: How do Doha and Soratha differ? A: Both have 24 matras per line, but Doha is 13 + 11 and Soratha is the reverse, 11 + 13, with the rhyme falling at the half-line.
• Q: Which metre did Kalidasa use for the *Meghaduta* and why does it suit the poem? A: Mandakranta - 17 syllables with a slow, "gently advancing" gait and caesuras at 4, 6 and 7 that suit the mood of separation and longing.
• Q: What is taqti' in Urdu prosody? A: Scanning a misra into its arkan by the rules of written-but-unpronounced letters and vowel shortening, to test whether the line fits a bahr; a failing line is *kharij-az-bahr*.
• Q: Distinguish radif from qafia. A: Qafia is the rhyming syllable or word; radif is the identical word or phrase repeated after it at the end of each rhyming line - a ghazal may be *gair-muraddaf*, that is, without radif.
• Q: What is Pingala's contribution beyond metre? A: His *Chhandahsutra* uses binary place-value notation for laghu-guru, gives the Meru-prastara (binomial triangle) and the matrameru - the Fibonacci recurrence - centuries before their European statement.
• Q: Why does metre matter to a textual editor? A: Scansion exposes corruption: a missing or extra syllable, or a wrong weight, localises the error and often indicates the correct reading.
• Q: What are the units of Tamil prosody, in order? A: Ezhuthu, asai (ner/nirai), cheer, thalai, adi, thodai and finally pa - the metre itself; the *Thirukkural* is in kural venba.
• Q: Who introduced free verse and blank verse in Hindi and Bengali? A: Nirala brought *mukt chhand* into Hindi with *Juhi ki Kali* (1916); Michael Madhusudan Dutt introduced *amitrakshar chhanda* (blank verse) in Bengali from 1860.
• Q: Can alliteration be part of metre? A: No - anuprasa and prasa are shabdalankara, figures of sound; metre concerns syllabic weight and count, though Tamil *thodai* and Kannada *prasa* are prescribed alongside the metre.

Common mistakes

• Counting letters instead of syllables: *kṛṣṇa* is two syllables, not five characters; conjuncts are one syllable but make the *previous* one guru.
• Forgetting that a conjunct in the next word lengthens the preceding syllable, and that anusvara and visarga make a short vowel guru.
• Reversing the Anushtubh rule - putting the laghu seventh syllable in the odd pada instead of the even one.
• Swapping Doha (13+11) and Soratha (11+13), or omitting the compulsory guru-laghu ending of the Doha's second half.
• Treating matras and syllables as the same count - a 17-syllable Mandakranta quarter has 27 matras.
• Mixing prosody with poetics: naming rasa, dhvani or alankara in a chhand answer, or calling anuprasa a metre.
• In Urdu, scanning the written form instead of the pronounced one - *izafat*, silent *h* and *alif-e-wasl* must be handled by taqti' rules before counting.
• Claiming free verse has "no rules" - it drops fixed metre but keeps rhythm, line-break and beat as its organising devices.
