Silhouette. What determines the silhouette of a poem?

Form?
Sound?
Line breaks?
Repetition and/or call and response?

Is a silhouette how a poem appears on the page? How a poem sounds in the ear? Or how the poem tastes in the mouth? Perhaps, when the constellations align -- all these.


Of the food taken tonight. The lacquer bowl held jasmine rice steeped in green tea, steamed skinny green beans, and wild salmon marinated with soy/wasabi & fresh ginger and then pan fried.
And when the lid removed from the lacquer bowl, silhouettes aplenty and non in opposition.

Same could be said of the tastes herein.
