Pantoum is basically a quartain based poem, modelled upon the Malay Pantun. However, I haven’t got any clue as to the relationship between both of them is established. It is generally written in a set of four line quartains. Even if there is a repetition of lines, but a change of meaning is intended when the line is repeated – by shifting punctuation marks or changing the context.
Quartain1 A B C D
Quartain2 B E D F
Quartain3 E G F H
Quartain4 G I H J
Note that I or J can be new lines or a repetition of the lines A or C and J
I believe, then, it will be nice to attempt the below sequence
A B A D
B E D F
E G F H
G A H A
but with different meanings for every line.
Coming to Pantun,
1. There is no standard, but the standard sequence followed is ABAB
2. The rythm is maintained across the lines
3. Number of syllables is 8-12 in every line
4. Even if ABAB is maintained, it’s intended that the first A differs in meaning from the second A and same goes for B.
