Rhyme and Rhythm
Rhyme means the recurrence of a similar sound at the closing syllables of different lines in poetry. It is actually the correspondence of the same sound at the terminating syllable or syllables. Two words that end with the same sound are said to rhyme. For example, words like bell and well share the same ending. Thus, they are rhyming words. It is mostly concerned with the words. It is not only helpful to memorize some things, but it is also a pleasure to the ear.
Ex. 1. A sunshiny shower
Won’t last an hour.
2. Twinkle, twinkle, little star,
How I wonder what you are!
Up above the world so high,
Like a diamond in the sky.
This differs from the rhythm which is determined by the periodical recurrence of pauses and accents and serves to produce a harmonious effect. Rhythm is the measured flow of words and phrases as measured by the relation of long and short or stressed and unstressed syllables. Rhythm is concerned with words, phrases, and lines. Rhythm can help to strengthen the meaning of words and ideas in a poem.
