Lục bát
The Six-Eight Verse — Vietnam's Most Beloved Poetic Form
Lục bát (六八, literally "six-eight") is the quintessential Vietnamese poetic form. It alternates 6-syllable and 8-syllable lines with strict rhyme and tonal rules, creating a flowing, musical rhythm that has captivated Vietnamese speakers for centuries.
Nguồn Gốc — Origins
Lục bát emerged around the 13th-14th centuries as a purely indigenous Vietnamese innovation, born from oral folk traditions. Unlike Chinese-origin forms (tứ tuyệt, thất ngôn bát cú), lục bát reflects the natural phonology and rhythm of spoken Vietnamese.
The form gained literary prestige in the 19th century when Nguyễn Du used it for his masterpiece Truyện Kiều (1820), a 3,254-line epic narrative considered the pinnacle of Vietnamese literature.
Today, lục bát appears in folk songs (ca dao), love poems, proverbs, lullabies, and even modern pop lyrics. It's the most recognizable Vietnamese poetic pattern.
Cấu Trúc — Structure
Basic Pattern
Line A: 6 syllables (ending rhyme X)
Line B: 8 syllables (syllable 6 rhymes with X, syllable 8 rhymes Y)
Line C: 6 syllables (ending rhyme Y)
Line D: 8 syllables (syllable 6 rhymes with Y, syllable 8 rhymes Z)
...and so on, creating an interlocking rhyme chain
Rhyme Rules
- Syllable 6 of the 6-line must rhyme with syllable 6 of the following 8-line
- Syllable 8 of the 8-line must rhyme with syllable 6 of the next 6-line
- Rhymes must match both final sound (vowel + ending consonant) and tone category (bằng or trắc)
- This creates a "chain rhyme" pattern where each couplet links to the next
Tonal Rules (Luật Bằng Trắc)
- Syllable 6 of the 6-line is usually bằng (ngang or huyền)
- Syllable 8 of the 8-line can be bằng or trắc, but must rhyme properly
- The pattern is more flexible than Chinese regulated verse, allowing natural Vietnamese speech rhythm
Ví Dụ Nổi Tiếng — Famous Examples
Example 1 — Truyện Kiều (Nguyễn Du, 1820)
The opening lines of Vietnam's national epic poem:
Trăm năm trong cõi người ta,
Chữ tài chữ mệnh khéo là ghét nhau.
Translation: "A hundred years in the span of human life / Talent and fate, how they hate each other."
Rhyme Analysis:
- • Line 1 (6 syllables): "ta" (ngang, bằng)
- • Line 2 (8 syllables): syllable 6 = "là" (huyền, bằng) rhymes with "ta" ✓ | syllable 8 = "nhau" (huyền, bằng)
- • Next 6-line would rhyme with "nhau"
Example 2 — Ca Dao (Folk Song)
A traditional love song about separation:
Thương nhau cởi áo cho nhau,
Gió nào khác nắng mua về mặc lại.
Translation: "When lovers part, give each other clothes / In any wind or sun, wear them again (to remember)."
Cultural Context:
This folk verse expresses Vietnamese values of loyalty and remembrance. The imagery of exchanging clothes symbolizes keeping a physical reminder of love during separation.
Example 3 — Lục Vân Tiên (Nguyễn Đình Chiểu, 1857)
A philosophical reflection on fame and love:
Công danh giấy một tờ,
Tình duyên giây một sợi mà thôi.
Translation: "Fame and glory are just a sheet of paper / Love and fate are just a thread, that's all."
Literary Device:
Uses đối (parallelism): "công danh" (fame) // "tình duyên" (love), "giấy một tờ" (sheet of paper) // "giây một sợi" (thread). This symmetry emphasizes the fragility of both worldly success and romantic bonds.
Example 4 — Ca Dao (Agricultural Life)
Trời mưa gió thổi mưa sa,
Anh đi cày ruộng em ra bừa bừa.
Translation: "Rain falls, wind blows, rain pours / You plow the fields, I'll harrow and till."
Depicts the partnership of rural couples working together in the rice fields.
Lục Bát Today
Lục bát remains widely used in contemporary Vietnamese culture:
- Pop music lyrics: Modern singers incorporate lục bát patterns for nostalgic or romantic effect
- Advertising slogans: Companies use lục bát to create memorable, culturally resonant taglines
- Wedding toasts and speeches: Formal occasions often feature lục bát verses
- Children's games and rhymes: Lục bát patterns appear in jump-rope songs and counting rhymes
- Political discourse: Slogans and propaganda often adopt lục bát for rhythmic impact
The form's flexibility and natural rhythm make it the "default" Vietnamese verse pattern — if you hear poetry in Vietnamese, there's a good chance it's lục bát.
Tips for Composing Lục Bát
- Count syllables carefully: Each Vietnamese syllable = 1 unit, regardless of length in English. "Trăm" (hundred) = 1 syllable, not two.
- Check rhyme category: Make sure rhyming syllables share the same tone category (both bằng or both trắc). "ta" (ngang) can rhyme with "là" (huyền), but NOT with "tá" (sắc).
- Use natural speech rhythm: Unlike regulated verse, lục bát allows flexibility. Read your lines aloud — they should flow like conversational Vietnamese.
- Study ca dao: Folk songs are the best source of authentic lục bát patterns. They show how everyday Vietnamese naturally falls into 6-8 rhythm.
- Avoid awkward tonal sequences: Too many trắc tones in a row sounds harsh. Mix bằng and trắc for musicality.
