Bahr
Quick answer: Bahr is the metre of Urdu, Persian and Arabic poetry, a fixed pattern of long and short syllables that every line of a ghazal must follow. Learn the basics.
Bahr is the metre of Urdu, Persian and Arabic poetry: a fixed pattern of long and short syllables that every line of a poem must follow. The word means sea in Arabic, and the image is apt, since the metre is the water the whole poem floats on. The system descends from arud, the science of prosody worked out by al-Khalil ibn Ahmad in eighth-century Basra, and it measures syllable weight rather than stress, which is what makes it feel unfamiliar to English ears.
In a ghazal, every couplet must sit in the same bahr, so the choice is made once and obeyed for the whole poem. Reciters and listeners internalise these patterns so deeply that a line even one syllable out of metre lands like a wrong note at a concert.
How a Bahr Is Built
Each bahr is assembled from metrical feet called arkan, memorised through nonsense words such as faulun, failatun and mafailun, whose own syllable weights encode the pattern. A short syllable is light, roughly 'ka'; a long one is heavy, roughly 'kaa' or a closed syllable like 'kar'. String the feet together and you get the line's rhythm. An English approximation of the flowing bahr-e-mutaqarib might run: 'the night / has a gate / and it opens / for grief', four small rising waves, though English stress can only gesture at what syllable weight does precisely.
The Classical Bahrs
Urdu manuals commonly list nineteen bahrs, most inherited from Persian, which took them from Arabic. Bahr-e-hazaj carries a huge share of famous ghazals, including many of Ghalib's. Bahr-e-ramal is the metre of Rumi's Masnavi. Bahr-e-mutaqarib drives Ferdowsi's Shahnameh through fifty thousand couplets. Arabic adds metres like kamil and wafir that Persian and Urdu use rarely. Each bahr also comes in variant lengths and clipped forms, so the practical family of usable rhythms is far larger than nineteen.
Do You Need Bahr in English?
Not literally, because English metre counts stresses, not syllable weights. But the discipline transfers. English ghazal writers usually substitute a steady syllable count or a consistent accentual pulse across lines, which honours the spirit of bahr: one music, chosen early, kept faithfully. Whatever system you use, scan your lines aloud; the ear catches what the eye forgives.
What poets can take from this
- Learn one bahr thoroughly before sampling others; depth beats a shallow tour of nineteen.
- Scan couplets by famous poets aloud until the pattern lives in your ear, not your notes.
- In English, pick a fixed syllable count per line as a working substitute for bahr.
- When a line refuses to fit, change the words, never the metre; the bahr is the contract.
- Record yourself reciting; a metrical stumble you cannot hear while reading is obvious on playback.
Try it yourself
Write six lines in English that all match one rhythm template of your own design, such as da-da-DUM repeated four times, and keep the pattern exact in every line.
Questions
What is the difference between bahr and arud?
Arud is the whole science of prosody, the rulebook; a bahr is one specific metre defined within that science. Arud tells you how to scan, and the bahr is the pattern you scan against.
How many bahrs are there?
Classical Arabic theory defines sixteen, and Urdu-Persian tradition commonly works with nineteen, each with many variant forms. In practice a handful of popular bahrs carry most of the ghazal tradition.
Must all couplets of a ghazal share one bahr?
Yes. A ghazal keeps a single bahr from first couplet to last, along with its qafiya and radif. That constancy is what lets each couplet change subject without the poem falling apart.
