Question

Wide-eyed clowns honk noses,

Toddlers shriek with glee,
A rogue balloon stops with a pop,
A big band blares its harmony.Which words create alliteration in the poem?

Answer 1

"A big band blares its harmony" is the Alliteration here. This is the definition of Alliteration to help with any other questions;
"The occurrence of the same letter or sound at the beginning of adjacent or closely connected words"
