How does the poet develop the poem’s tone through the use of alliteration?

(this is the poem):

The truth is, every day we rise is like thunder —

a clap of surprise. Could be echoes of trouble, or blossoms

of blessing. You never know what garish or gorgeously

disguised memories-to-be might rain down from above.

So, look up! Claim that cloud with the silver lining. Our

job, if you ask me, is to follow it. See where it heads.
