That’s a neat find. There’s an old Cornish ballad called “The Witches’ Moon” where the verses line up with waxing and waning—each stanza starts with a word that counts the days. I also stumbled on a 19th‑century Appalachian lullaby, “The Moon’s Secret Waltz,” where the rhythm shifts in sync with lunar crescents, almost like a hidden metronome. And in some Siberian shamanic chants, the syllables are intentionally spaced to mirror the moon’s cycle; the elders called it the “Phase Echo.” I’d wager there are dozens more buried in forgotten hymnals, but I’d need to sift through a few hundred pages before I can claim any of them outright.
