flaw
sleeps in
the framework

creaking above you

while a minor tilt tilts some more
amid relentless shuddering of rusted spines

the geometry of denial can no longer contain the pandemonium

Fibonacci, 1-1-2-3-5-8-13-21

The form, according to Robert Lee Brewer, was developed by Gregory K. Pincus in 2006 based on the mathematical Fibonacci sequence.

“There are variations where the Fibonacci expands even further with each line, but to understand how to accomplish this, you need to understand the Fibonacci math sequence of starting with 0 and 1 and then adding the last two numbers together to add to infinity.

0+1=1
1+1=2
1+2=3
2+3=5
3+5=8
5+8=13
8+13=21
13+21=34
and so on and so forth…”

Since 21 syllables or more are increasingly unwieldy, one can use other variations such as a Fibonacci poem that ascend and descend in syllables: 1 – 1 – 2 – 3 – 5 – 8 – 8 – 5 – 3 -2 – 1 – 1
