Two lines of the same meter having the same rhyme. Commonly used in simple single rhyme schemes and basic lyric structures. Couplets may be more complex, despite this apparently simplistic basic form. Rhyming couplets are far more common in modern song lyrics than in poetry, where the fact of having the same meter and therefore the same rhythm serves a useful purpose for the lyricist. The rhyming couplets are also common in advertising hook lines, like 'Whiter and brighter', or 'Moon in June'. The intention is to provide a simple, memorable, association of rhyming words in context with theme.
