How does strophic form connect the verses of a hymn or folk song?

In musical form, strophic form connects the verses of a hymn or folk song by setting different poetic strophes—or stanzas—to the exact same melody.12

While the text changes with each successive stanza, the underlying musical tune remains constant, repeating for every verse of the song. This structure serves as a unifying framework, allowing the listener to focus on the evolving narrative or lyrical content while maintaining a familiar and consistent musical experience throughout the entire piece. This approach is a hallmark of traditional ballads and hymns, providing a simple yet effective way to organize songs that contain multiple verses.12
