"Harmony" tells the story of a lover's return after a long time apart. The lyrics capture the singer's complex feelings, as he wonders if he's merely a last resort, yet still expresses his unwavering love. While the words convey optimism, the music itself hints at a deeper, possibly fleeting happiness, even being described as a "dirge of despair" that still manages to soar with hope. This song, the final track on the 1973 album Goodbye Yellow Brick Road, explores the fragile balance between hope and underlying doubt in reunion. At its heart, it plays like a bittersweet embrace of love despite lingering uncertainties.
