How did Gerard Manley Hopkins use accentual metre in sprung rhythm?

Gerard Manley Hopkins developed sprung rhythm as an irregular system of prosody based on the number of stressed syllables in a line, while permitting an indeterminate number of unstressed syllables.1

In this system, Hopkins utilized accentual metre—which counts only the number of stresses and allows for a variable number of unaccented syllables—as the foundation for his innovation. Unlike traditional English metres, where a foot typically consists of two or three syllables, a foot in sprung rhythm may be composed of one to four syllables.21

Because stressed syllables often occur sequentially rather than in alternation with unstressed ones, the rhythm is described as "sprung". Hopkins viewed this as the rhythm of common English speech and sought a stronger "rhetoric of verse," resulting in a muscular, flexible, and intense style that bridges the gap between regular metre and free verse.13
