Fibonacci poetry is based on a number sequence.
Typically a Fibonacci poem has 6 lines and 20 syllables.
Many poets are experimenting with the Fibonacci form and Fib poems can, and do, go into longer sequences.
Some also reverse the sequence. Some Fibonacci poems use words instead of syllables as their counter.
The main requirement these days is to keep the numbering sequence consistent.
The Fibonacci Sequence mathematically is as follows: 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on. You get my meaning.
It is also found in nature. The Fibonacci sequence is often the form that underlines patterns.
The Fib Review has some wonderful examples of Fibonacci poems.
For an example of one of my own attempts at a Fibonacci I’ve posted Moment.
