It does follow a fairly simple pattern
for the repetition of a fixed word
in each line. The words occur as end
words in a set order in each line,
but you can think of it as a repeated

composition. It brings us back to repeat
a bit of the history of the pattern:
it traveled throughout elaborate lines
and difficult styles in the court of words.

But, the most powerful of the words
started as an oral tradition repeated
in sound and meter. That is how a line
enters hearts: when you hear the pattern
begin in the words, then change and end.
