Accentual verse has a fixed number of stresses per line or stanza regardless of the number of syllables that are present. It is common in languages that are stress-timed, such as English—as opposed to syllabic verse, which is common in syllable-timed languages, such as French. Accentual verse is particularly common in children's poetry – nursery rhymes and the less well-known skipping-rope rhymes are the most common form of accentual verse in the English Language. The following poem, Baa Baa Black Sheep, has two stresses in each line, but a varying number of syllables. (Underline represents stressed syllables, and the number of syllables in each line is noted) [fieldset=Baa Baa Black Sheep]Baa, baa, black sheep, (4) Have you any wool? (5) Yes sir, yes sir, (4) Three bags full; (3) One for the mas-ter, (5) And one for the dame, (5) And one for the lit-tle boy (7) Who lives down the lane.
