poetry sounds

At first, I thought rhyme was the sound of music, but I learned that rhyme is the repeating of the sound of the stressed vowel and any sounds that follow.
An example of a poem with end rhyme is below
Little about passion

Passion kills,
Passion thrills,
Passion fills,
with a sense of purpose..........

Passion may chill,
Passion makes ill,
Passion is still,
Pain mistaken as passion........
The title is Passion Kills,and the author is Mahfooz Ali.The rhyme scheme is end rhymes.
On my poetry pretest, I was below grade level.
On my posttest, I hope that I will be above grade level.
