Haiku is a short form of poetry adapted from Japanese tradition. Each poem consists of three lines; the first line has five syllables, the second line has seven syllables, and the third line has five. (5-7-5) Find an interesting place where you can sit and observe, uninterrupted. Focus on a tiny, detail -- a color, a texture, a movement. Create a haiku by describing (literally or figuratively) that detail in just 17 syllables.
Traditionally, haiku are based on observations of the natural world -- explaining a small moment, but can be used for any subject matter. They are usually written in the present tense, about the present moment. Example: Whitecaps on the bay: A broken signboard banging In the April wind. - Richard Wright
