Poetry is an art and a discipline that ranges from whatever goes to the very specifics of form and use of language.
It can take many shapes from free verse that is open in structure to a fixed form that follows specific rules to the semi-fixed form of prose poems. The fixed forms include sonnets, sestinas, villanelles or haikus that have specific meters, syllable counts and rhyming schemes. Prose poems combine poetry and prose through a block of text written in poetic language.
Poems, no matter their structure, are about feeling, emotion, stories and moments. They have tempo, rhythm, color, sound and movement as they capture an experience, thought, idea or observation.
This capturing is done in language of beauty, awe and difference. To make that capture different than that of writing prose, poems employ various poetic devices that add musicality to the words.
Some of those devices include alliteration, the repetition of initial consonant sounds; consonance, the repetition of internal consonant sounds; and assonance, the repetition of vowel sounds. There also is onomatopoeia, or words that imitate the sounds they stand for, such as hiss, buzz or squawk, and slant rhyme, the similar sound of two words that are nearly identical.
Free verse poetry doesn’t have a specific meter or syllable count or a consistent rhythm and sound. This form is open but still engages one or more of the poetic devices.
Poems typically fall into two categories, lyrical or narrative. A lyrical poem is a snapshot or a fixed moment of time; it is a poem of a single image, thought or emotion. A narrative poem tells a story and has a plot with beginning, middle and end.
Poetry, no matter its form, shape or the devices it uses, becomes art as it uses language to create something of beauty, and its craft through the employment of those devices to make that beauty.
Poetry, in essence, is art, craft and a bit of magic that comes from inspiration, word play and discovery.
