Todd nailed what I was after: How do we successfully incorporate sound into our poems, along with images?

Verbs are I think the sound in words, and good verbs that come closet to sound is, like you said, onomatopoeias. Syllables accents and unaccents, perhaps in a meter, makes you "hear" in your head a word's sound and the entire sound of a poem, if there is a meter. It's like "Paul Revere's Ride" poem's galloping meter which makes you hear a horse galloping, which has to be heard in the context. Context itself has cultural sounds, like the Spanish phrase, "Ay caruamba!"
