Structure, Metrical Requirement, End Word Requirement, Isosyllabic
Bob Newman has taken the general idea of the sestina and extended it both upwards and downwards from the six-line stanza it normally uses. The Bina is the two-line stanza version. Like the sestina, it is preferable to use isosyllabic lines.
End word repetition pattern:
It is much shorter and more practical that the sestina.
Having shorter stanzas, the end words come back very quickly, so while it isn’t as repetitive and possibly monotonous as the sestina, they will be a very strong presence in the poem. This could make the poem somewhat comic, intentionally or not.
Because it is only five lines, the flexibility of the end words is not nearly as important as in the sestina; however, they should be chosen well enough that they can be used three times each in five lines and not grate on the nerves.
For “that blackcurrant drink – is any left?”
I wonder, now that she’s grown up and left,
If maybe I indulged her for too long.
When in the tooth she’s long, she’ll have none left.
