In the same vein as Torana's Colour Imagery challenge, it occurred to me that sound imagery is often neglected in poetry. Sound imagery? Isn't that an oxymoron? You don't see sounds! No, but imagery encompasses more that description of visual elements. All five senses participate in perception, and good imagery related to the other four senses can greatly enrich the reader's involvement. So select a sound, and try describing it vividly, so a reader will recognize the sound in all its nuances, and tie it to an emotional reaction. Good luck, and have fun with it!
I've tried describing a dog's bark- A sound yells out from deep within the creature, containing a slight hint of aggression and the faintest sliver of fear. It begins with an attack of sharp noise and progresses into a mellow reflection, only to be followed by another sharp note. This assault of sound continues until its bearer grows tired of the echo of noise that has splintered the air and all that is left is the dull suggestion that a sound occurred moments earlier. It's not great and could be expanded on, I'm sure. ETA: Oh dear, my first day here and I'm already spamming the boards.
Wind whispers, a soft sibilant sigh, stirring dry leaves as it caresses the trees with but one word: why?
The violin plays low morbid wail. Screaming solace cationairy tale growing ever higher like a shriek caught in throat The bow moves across strings in an ambient little croak The breaks into life again a sudden dance of hope.
