Song

Gillan Welch uses repetition and internal rhyme in his song "Dark Turn of Mind" to emphasize what he is singing about. He uses repetition to express his senses, "Now I see the bones in the river/ And I feel the wind through the pine/ And I hear the shadows a-calling..." The senses he is expressing is sight, touch, and hearing to show what the mood is like.

Welch also uses internal rhyme to express the mood of the song. He sings, "But oh ain't the nighttime so lovely to see?/ Don't all the nightbirds sing sweetly?" The words "nighttime" and "nightbird" tells that the it is night but they also make the mood of the song more calm.
