Assonance

Nine Blind Mice

Jack sat on the mat

The Eight Elegant Elephants

Hack the stack

The hiker was swimming

Consonance

Cat in the hat

Smash the Glass

Through the looking glass

Smack the bat

Seashells on the Seashore

Oxymoron

Exit enter

Light darkness

Loud silence

Quiet Noise

Clear fog
