Syllable-count patterns often are used in poems--helping to give a rhythmic tempo to the words. As I mention often, syllable counts -- and other word-patterns -- help me to discover new and special meanings to convey. When I start to write, my thoughts are scattered and need to be gathered and focused -- and a poetic form helps this to happen. The sonnet and the villanelle have long been valued examples of poetry patterns. More recent -- and more simple -- is the Fib. Introduced by poet Gregory Pincus back in 2006, the Fib is a six-line poem whose syllables are counted by the first six Fibonacci numbers: 1, 1, 2, 3, 5, 8. (Each succeeding Fibonacci number is the sum of the two that precede it.)
Since 2006, a journal aptly named The Fib Review has offered (available at this website) more than 40 issues of poems, all of whose lines have syllable-counts that are Fibonacci numbers. Here is a portion of one of the poems -- by Washington-based poet Sterling Warner -- (the complete poem is found here).
