What is a lyric essay?

“Writing the lyric essay offers the author a frolic in the pool of memoir, biography, poetry and personal essay mixed with a sprinkling of experimental… and flash fiction. In lyric essay the narrative might break up into sections, evolve and trail away into white space, poetry and often, repetition.The author’s imagination can explode with the possibilities.”

I’m finishing up the umpth version of my memoir and have been inspired to write lyric essays as a way of remembering glimmers of my childhood, especially.
