• Tho Bay Chu or Seven Word Poetry is written with seemingly more flexible tonal pattern than most Viet verse with the exception of when an end word is flat, the 3rd word must be sharp and when the end word is sharp, the 3rd word in the line must be flat.
Tho Bay Chu is:
○ stanzaic, written in any number of quatrains.
○ measured by number of words, 7 words per line.
○ rhymed, tonal rhyme appears to be at the discretion of the poet except if and end word is flat, the 3rd word of the line must be sharp or if the end word is sharp, the 3rd word of the line must be flat. End rhyme aaxa bbxb etc. or xaxa xbxb etc.
