No, Gregorian chant is characterized by a specific rhythm known as a non-metric or free rhythm, where the timing of the notes is based more on speech patterns than on a regular beat.
There isn't a requirement of rhythm for a free verse poem.
Free verse has variable rhythm.
Donald Davie's Some Notes on Rhythm in Verse was created in 1972.
a verse
verse is a verse or poem that doesn't rhyme but has a strict rhythm, usually iambic pentameter.
Blank verse is characterized by its regular meter (iambic pentameter) and unrhymed lines. You can tell a poem is written in blank verse by counting the syllables in each line and noticing the natural flow and rhythm without any rhyme scheme present.
This verse is part of the text of the traditional chant "In Paradisum, deducant te angeli" which is part of the traditional Roman Catholic funeral rite. The music can be found in the Liber Usualis and many pre Vatican II hymnals. It can be heard on many Gregorian Chant recordings.
