Cantus firmus jumps around between voices. Melody of the chant is always in there somewhere (two small adjustments to accommodate harmonic structure).

Perform wherever, whenever. Please let me know if so, and share any recordings (if available).

Hail, true Body, born of Mary the Virgin; truly suffering, sacrificed on the
cross for man; from Whose pierced side flowed water and blood. Be to us a
foretaste at death’s trial, O sweet Jesus, O loving Jesus, O Jesus Son of Mary.
