Perfect and imperfect rhymes
rhyme which satisfies certain conditions on the phonemes of the words involved
Perfect rhyme (also called full rhyme, exact rhyme, or true rhyme) is a form of rhyme between two words or phrases, satisfying the following conditions:
The stressed vowel sound in both words must be identical, as well as any subsequent sounds. For example, the words kit and bit form a perfect rhyme, as do spaghetti and already in American accents.
The onset of the stressed syllable in the words must differ. For example, pot and hot are a perfect rhyme, while leave and believe are not.
Word pairs that satisfy the first condition but not the second (such as the aforementioned leave and believe) are technically identities (also known as identical rhymes or identicals). Homophones, being words of different meaning but identical pronunciation, are an example of identical rhyme.
Imperfect rhyme
Half rhyme or imperfect rhyme, sometimes called bastard rhyme, near-rhyme, lazy rhyme, or slant rhyme, is a type of rhyme formed by words with similar but not identical sounds. In most instances, the vowel segments are different and the consonants are identical or vice versa. This type of rhyme is also called approximate rhyme, inexact rhyme, imperfect rhyme (in contrast to perfect rhyme), off rhyme, analyzed rhyme, suspended rhyme, or sprung rhyme.
Use in popular music
Rock and punk
