Meaning and Expression. The music twice repeats an earlier passage from measures 16–19, conveying some of the same sense of harmonic, melodic, and motivic confinement in a narrow place. But two features give a greater sense of urgency. First, the two singers have shorter and shorter utterances: Tom sings for sixteen measures, then Anne for eight, and finally Tom for four. Second, the repetition itself, including the fifth and sixth antecedent phrases, creates growing pressure toward a change and a resolution of some kind.
