Back in March, I transcribed "Thy Body, Given for Me, O Savior" (sung to the tune "Ich sterbe täglich") and noticed a small thing about it.
The third line of the first verse is "These [Christ's body and blood] are my life and strength forever," sung to this phrase:
"Forever" is sung with a melisma (G E D C), and since the word is drawn out, there's something of a sense of that long period of time.
