11. Rhymth :]

Definition: A musical quality created by the repetition of stressed and unstressed syllables.

"The Assyrian came down like the wolf on the fold,
And his cohorts were gleaming in purple and gold;
And the seen of their spears was like stars on the sea,
When the blue wave rolls nightly on deep Galilee."
-"The Destruction of Sennacherib"

Significance: Rhymth is very important in a poem because it creates a musical poem out of a regular one and it is also very easy for readers to memorize.
