Country singer Harper Grace has released a new single, "Underneath the Harvest Moon," a romantic dance track whose chorus line about being in a "knockin'-boots kinda mood" has left her slightly anxious about being misread. The phrase carries sexual connotations in popular culture, drawn from songs by Luke Bryan, Candyman and H-Town, but Grace insists she simply intended it as an image of dancing, prompting her to stress that listeners should understand it as "just a dancing song."

Grace, a Texas native signed to Curb Records, wrote the track in 2021 at age 21 during a session at East Nashville studio The Shed with writer-producers Cameron Jaymes and Steve McEwan. The song developed from unconventional major-seventh guitar chords and a Wurlitzer-driven "yacht-rocky" sound, with the "harvest moon" concept – the full moon nearest the autumn equinox – shaping a storyline about romance under moonlight rather than in a honky tonk, complete with barroom and jukebox imagery to set a sassy tone.
