Because Sunday was the Feast of St. Michael and All Angels, one of the hymns in church was "Christ, the Lord of Hosts, Unshaken." I think this was the first time I'd sung it, and I noticed a small feature in it.
The fifth line of the first verse is "Conquers sin and death forever," sung to this phrase from the tune "Fortunatus New":
"Forever" is sung with a melisma (G Bb A A), and because it's stretched out, there's a musical sense of duration.
