So basically, what I want to say is something along the lines of, "He begins his story with a rhyme" or, "He tells a poem and begins his story". What's the word for "tell" here? Is there a verb phrase for this in Japanese?
(By "rhyme" or "poem", I mean something like a "言い習わし" (short Japanese saying), but in the form of a poem. The closest word I could find to it was "散文" and that's why I am using it, but I am open to any suggestions.)
Edit: Can I use,
彼は散文で物語を始めます。
???
