How does the author use repetition and rhythm in the folktale, The Village Witch Doctor?

The Village Witch Doctor is structured by a rhythm of anticipated repetitions. The male of each generation of the family in the story; Aro, Jaye, and Ajaiyi, follows a similar set of experiences and actions. Both Aro and Ajaiyi go repeatedly to the village witch doctor for advice, and are repeatedly deceived by him. Aro and Jaye, and their wives, each die "suddenly" of poverty. Repeated actions are also taken by individual characters. For example, Ajaiyi has no choice but to pawn his labor for money three different times in the story.
