A perfect rhyme (night / light) feels closed and final. A near rhyme shares only the vowel (night / time) or only the ending sound — it feels softer and more natural, and gives you many more words to choose from.
- Use tight rhymes where you want things to feel settled — often the chorus — and looser ones elsewhere.
- Keep the rhyme pattern the same from verse to verse, and from chorus to chorus.
- Even numbers of lines, of equal length, feel settled. An odd number of lines, or one longer line, feels restless — good for longing, or for a part that should push forward.
- Put the stressed syllables on the strong beats. Say the line out loud: the words you lean on (nouns, verbs) belong on beats 1 and 3, the little words (the, of, and) in between.
- Keep held notes on open vowels (oh, ah, ay), and keep tongue-twisters out of fast lines.
