A metrical system devised by Gerard Manley Hopkins
composed of one- to four-syllable feet that start with a stressed syllable. The spondee
replaces the iamb as a dominant measure, and the number of unstressed syllables varies considerably from line to line (see also accentual verse
). According to Hopkins, its intended effect was to reflect the dynamic quality and variations of common speech, in contrast to the monotony of iambic pentameter.
His own poetry illustrates its use; though there have been few imitators, the spirit and principles of sprung rhythm influenced the rise of free verse
in the early 20th century.
