Last weekend, teaching-writers Chris Martin and Brian Laidlaw presented at the 21st Annual Minnesota Autism Conference. Their presentation, "Turning Perseveration into Creativity," focused on how repetition and so-called "restricted interests" are both crucial to the structure of poetry and song. What would a villanelle be without repetition? Isn't rhyme basically perseverative? And don't these cyclical preoccupations help ground the writing and make its concerns immediately legible for the reader or listener? With all their experience as celebrated poets and songwriters (and teachers) behind them, Chris and Brian gave a definitive answer: yes.
