Definition: Rhythm is a pattern of stressed and unstressed syllables.
Example: The rain in Spain falls mainly on the plain.
In this phrase, every other syllable is stressed.
Significance: Rhythm is important because it makes poetry sound more song-like and musical. Since poetry is written to be read aloud, poems with rhythm make the poem more uniform and sound nice. Rhythm is even noticeable when read silently since the mind automatically stresses certain syllables.
